PRODUCT INFORMATION 
 
HMO-1601 is an excellent disease control agent when used according to label directions for control of a 
broad spectrum of plant diseases. HMO-1601 is recom mended for use in programs which are compatible 
with the principles of Integrated Pest Management (IPM), which include the use of disease resistant crop 
varieties, cultural practices, pest scouting and disease forecasting systems which reduce unnecessary 
applications of pesticides. 
 
HMO-1601 is effective for strategic use in programs that attempt to minimize disease resistance to 
fungicides. Some other fungicides which are at risk from disease resistance exhibit a single-site mode of 
fungicidal action HMO-1601 with a multi-site mode of action, may be used to delay or prevent the 
development of resistance to single-site fungicides. Consult with your Federal or State Cooperative 
Extension Service representatives for guidance on the proper use of HMO-1601 in programs which seek 
to minimize the occurrence of disease resistance to other fungicides. 
 
HMO-1601 can be used effectively in dilute or concentrate sprays. Thorough uniform coverage is 
essential for disease control. 
 
Precautions and Restrictions 
 
DO NOT use on greenhouse-grown crops except as dire cted in the ORNAMENTAL PLANTS section of 
this label. 
 
Do not apply when wind speed favors drift beyond the target area. Observe all spray drift precautions for 
ground, aerial, and chemigation applications. 
 
Do not combine HMO-1601 in spray tank with pesticides, surfactants or fertilizers, unless your prior use 
has shown the combination physically compatible, effective and noninjurious under your conditions of 
use. Do not combine HMO-1601 with Dipel®, Latron B- 1956® or Latron AG-98® as phytotoxicity may 
result from the combination when applied to the crops on this label.

Filename: HMO-1601 Fungicide (5905-602) 103118 STK.docx ~ 5 ~ 
 
This product must not be applied within 150 feet for aerial applications, or 25 feet for ground applications 
of marine/estuarine water bodies unless there is an untreated buffer area of that width between the ar ea 
to be treated and the water body. 
 
Spray Drift Precautions 
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many 
equipment and weather related factors determine the potential for spray drift. The applicator and the 
grower are responsible for considering all these factors when making decisions. The following drift 
management requirements must be followed to avoid o ff target drift movement from aerial applications to 
agricultural field crops. These requirements do not apply to conifer applications, public health uses or 
applications using dry formulations. 
 
 
1. The distance of the outer most nozzles on the bo om must not exceed 3/4 the length of the wingspan o r 
rotor. 
 
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards 
more than 45 degrees. 
 
Where states have more stringent regulations, they should be observed. 
 
The applicator should be familiar with and take into account the information covered in the Aerial Drift 
Reduction Advisory Information. 
 
Aerial Drift Reduction Advisory Information 
 
[This section is advisory in nature and does not supersede the mandatory label requirements] 
 
Information on Droplet Size 
The most effective way to reduce drift potential is to apply large droplets. The best drift management 
strategy is to apply the largest droplets that provide sufficient coverage and control. Applying larger 
droplets reduces drift potential but will not prevent drift if applications are made improperly or under 
unfavorable conditions (See Wind, Temperature) 
 
Controlling Droplet Size 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher 
rated flows produce larger droplets. 
• Pressure - Do not exceed the nozzle manufacturer's recommen ded pressures. For many nozzle types, 
lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles 
instead of increasing pressure. 
• Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage. 
• Nozzle Orientation - Orienting the nozzles so that the spray is released parallel to the airstream 
produces larger droplets than other orientations and is the recommended practice. Significant deflection 
from horizontal will reduce droplet size and increase drift potential. 
• Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, 
narrower spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles 
oriented straight back produce the largest droplets and the lowest drift potential. 
 
Boom Length 
For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length 
may further reduce drift without reducing swath width.

Filename: HMO-1601 Fungicide (5905-602) 103118 STK.docx ~ 6 ~ 
Application Height 
Applications should not be made at a height greater than 10 ft above the top of the largest plants, un less 
a greater height is required for aircraft safety. Making applications at the lowest height that is safe 
reduces exposure of droplets to evaporation and wind. 
 
Swath Adjustment 
When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the 
upwind and downwind edges of the field, the applicator must compensate for this displacement by 
adjusting the path of the aircraft upwind Swath adjustment distance should increase with increasing dr ift 
potential (higher wind, smaller drops, etc.). 
 
Wind 
Drift potential is lowest between wind speeds of 2-10 mph. However many factors, including droplet size 
and equipment type determine drift potential at any given speed. Application should be avoided below 2 
mph due to variable wind direction and high inversion potential. 
 
NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind 
patterns and how they affect spray drift. 
 
Temperature and Humidity 
When making applications in low relative humidity, set up equipment to produce larger droplets to 
compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 
 
Temperature Inversions 
Applications should not occur during a temperature inversion because drift potential is high. Temperat ure 
inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentr ated 
cloud. This cloud can move in unpredictable directions due to the light variable winds common during 
inversions. Temperature inversions are characterized by increasing temperatures with altitude and are 
common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and 
often continue into the morning. Their presence can be indicated by ground fog, however, if fog is not 
present, inversions can also be identified by the m ovement of smoke from a ground source or an aircraf t 
smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind 
conditions) indicates an inversion while smoke that moves upward and rapidly dissipates indicates good 
vertical air mixing. 
 
Sensitive Areas 
The pesticide should only be applied when the poten tial for drift to adjacent sensitive areas (e.g., 
residential areas, bodies of water, known habitat for threatened or endangered species, nontarget crops) 
is minimal (e.g., when wind is blowing away from th e sensitive areas). 
 
RESISTANCE MANAGEMENT 
For resistance management, AmTide Propiconazole 41.8% EC Fungicide contains a Group 3 fungicide/bactericide. 
Any fungal/bacterial population may contain individuals naturally resistant to AmTide Propiconazole 41.8% EC 
Fungicide and other Group 3 fungicides/bactericides. A gradual or total loss of pest control may occur over time if 
these fungicides/bactericides are used repeatedly in the same fields. Appropriate resistance-management strategies 
should be followed. 
To delay fungicide/bactericide resistance, take one or more of the following steps: 
• Rotate the use of (name of product) or other Group (mode of action group number) fungicides/bactericides 
within a growing season sequence with different groups that control the same pathogens. 
• Use tank mixtures with fungicide/bactericides from a different group that are equally effective on the target 
pest when such use is permitted. Use at least the minimum application rate as labeled by the manufacturer. 
• Adopt an integrated disease management program for fungicide/bactericide use that includes scouting, uses 
historical information related to pesticide use, and crop rotation, and which considers host plant resistance,

Filename: HMO-1601 Fungicide (5905-602) 103118 STK.docx ~ 7 ~ 
impact of environmental conditions on disease development, disease thresholds, as well as cultural, 
biological and other chemical control practices. 
• Where possible, make use of predictive disease mod els to effectively time fungicide/bactericide applications. 
Note that using predictive models alone is not sufficient to manage resistance. 
• Monitor treated fungal/bacterial populations for r esistance development. 
• Contact your local extension specialist or certifi ed crop advisor for any additional pesticide resistance-
management and/or IPM recommendations for specific crops and pathogens. 
• For further information or to report suspected res istance contact Helena Agri-Enterprises, LLC at 901-761-
0050 or at Helenaagri.com. You can also contact your pesticide distributor or university extension specialist 
to report resistance. 
 
APPLICATION 
Dosage rates on this label indicate pints of HMO-1601 per acre unless otherwise stated. Under conditions 
favoring disease development the highest rate specified and shortest application interval should be used. 
 
NOTE: Slowly invert container several times to assure uniform mixture. 
 
The required amount of HMO-1601 should be added slo wly into the spray tank during filling. With 
concentrate sprays, pre-mix the required amount of HMO-1601 in a clean container and add to the spray 
tank as it is being filled. Keep agitator running when filling spray tank and during spray operations. 
 
Apply HMO-1601 in sufficient water to obtain adequa te coverage of foliage. Gallonage to be used will 
vary with crop and amount of plant growth. 
 
For turf, field and row crops spray volume usually will range from 20 to 150 gallons per acre for dilute 
sprays and 5 to 10 gallons per acre for concentrate ground sprays and aircraft applications. 
 
For tree and orchard crops apply HMO-1601 in suffic ient water and with proper calibration to obtain 
uniform coverage of tree canopy. For fruit and nut bearing crops the maximum volume is 300 gallons per 
acre unless indicated otherwise in the specific use directions. For conifers the maximum volume is 100 
gallons per acre. 
 
Application and Calibration Techniques for Chemigat ion 
Apply this product only through center pivot, motorized lateral move, traveling gun, solid set and portable 
(wheel move side roll, end tow, or hand move) irrigation system(s). Do not apply this product through any 
other type of irrigation system. 
 
Crop injury lack of effectiveness or illegal pesticide residues in the crop can result from non-unifor m 
distribution of treated water. 
 
If you have questions about calibration, you should contact State Extension Service specialists, 
equipment manufacturers or other experts. 
 
Do not apply this product through irrigation system s connected to a public water system. “Public water 
system” means a system for the provision to the public of piped water for human consumption if such 
system has at least 15 service connections or regul arly serves an average of at least 25 individuals daily 
at least 60 days per year. 
 
Controls for both irrigation water and pesticide injection systems must be functionally interlocked, s o as to 
automatically terminate pesticide injection when the irrigation water pump motor stops. A person 
knowledgeable of the irrigation system and responsible for its operation shall be present so as to 
discontinue pesticide injection and make necessary adjustments, should the need arise. 
 
The irrigation water pipeline must be fitted with a functional automatic, quick-closing check valve to 
prevent the flow of treated irrigation water back toward the water source. The pipeline must also be f itted

Filename: HMO-1601 Fungicide (5905-602) 103118 STK.docx ~ 8 ~ 
with a vacuum relief valve and low pressure drain located between the irrigation water pump and the 
check valve, to prevent back-siphoning of treated irrigation water into the water source 
 
Always inject HMO-1601 into irrigation water after it discharges from the irrigation pump and after 
it passes through the check valve. Never inject pes ticides into the intake line on the suction side 
of the pump. 
 
Pesticide injection equipment must be fitted with a functional, normally closed, solenoid-operated valve 
located on the intake side of the injection pump. Interlock this valve to the power system so as to pr event 
fluid from being withdrawn from the chemical supply tank when the irrigation system is either 
automatically or manually turned off. 
 
The pesticide injection pipeline must contain a functional, automatic quick-closing check valve to pre vent 
the flow of fluid back toward the injection pump. 
 
The irrigation line or water pump must include a functional pressure switch which will stop the water pump 
motor when the water pressure decreases to the point where pesticide distribution is adversely affecte d. 
 
Spray mixture in the chemical supply tank must be a gitated at all times otherwise settling and uneven 
application may occur. Do not apply when wind speed favors drift beyond the area intended for treatment. 
 
Systems must use a metering pump, such as a positiv e displacement injection pump (e.g., diaphragm 
pump), effectively designed and constructed of mate rials that are compatible with pesticides and capab le 
of being fitted with a system interlock. 
 
HMO-1601 may be used through two basic types of spr inkler irrigation systems as outlined in Sections A 
and B below. Determine which type of system is in place then refer to the appropriate directions provided 
for each type. 
 
A. Center Pivot, Motorized Lateral Move and Traveling Gun Irrigation Equipment 
For injection of pesticides, these continuously moving systems must use a positive displacement inject ion 
pump, of either diaphragm or piston type, constructed of materials that are compatible with pesticides and 
capable of being fitted with a system interlock and capable of injection at pressures approximately 2 to 3 
times those encountered within the irrigation water line. Venturi applicator units cannot be used on these 
systems. 
 
Fill chemical supply tank of injection equipment with water. Operate system for one complete revolution or 
run across the field, measuring time required, amou nt of water injected, and acreage covered. Thoroughly 
mix recommended amount of HMO-1601 for acreage to b e covered into same amount of water used 
during calibration and inject into system continuously for one revolution or run. Mixture in the chemi cal 
supply tank must be continuously agitated during the injection run. 
Shut off injection equipment after one revolution or run, but continue to operate irrigation system un til 
HMO-1601 has been cleared from last sprinkler head. 
 
B. Solid Set and Portable (Wheel Move, Side Roll, E nd Tow, or Hand Move) Irrigation Equipment 
With stationary systems, an effectively designed in-line venturi applicator unit is preferred which is 
constructed of materials that are compatible with pesticides however a positive-displacement pump can 
also be used. 
 
Determine acreage covered by sprinkler Fill tank of injection equipment with water and adjust flow to use 
contents over a 30 to 45 minute period. Mix desired amount of HMO-1601 for acreage to be covered with 
water so that the total mixture of HMO-1601 plus water in the injection tank is equal to the quantity of 
water used during calibration and operate entire system at normal pressures recommended by the 
manufacturer of injection equipment used for amount of time established during calibration. Agitation is 
recommended HMO-1601 can be injected at the beginni ng or end of the irrigation cycle or as a separate

Filename: HMO-1601 Fungicide (5905-602) 103118 STK.docx ~ 9 ~ 
application. Stop injection equipment after treatme nt is completed and continue to operate irrigation 
system until HMO-1601 has been cleared from last sp rinkler head.

Apply HMO-1601 in sufficient water and with proper calibration to obtain uniform coverage of tree cano py. 
For fruit and nut bearing crops, the maximum volume is 300 gallons per acre unless indicated otherwise 
in the specific use directions. For conifers, the maximum volume is 100 gallons per acre. 
Application with ground equipment is preferable to aerial application, because ground applications 
generally give better coverage of the tree canopy. If application with ground equipment is not feasible, 
HMO-1601 may be applied with aircraft using at least 20.0 gallons of spray per acre. The minimum 
volume for application by aircraft to conifer stands and Christmas trees is 10.0 gallons per acre.

• Stem Rust: Puccinia graminis 
• Dichondra Leaf Spot: Alternaria spp. 
• Gray Snow Mold: Typhula spp. 
• Pink Snow Mold, Microdochium Patch: Microdochium nivale 
 
 
Gray Snow Mold caused by Typhula spp.: 
 
Group A and B Turf: Apply in sufficient water to obtain adequate coverage (2 to 4 gallons per 1,000 sq 
ft). Apply one application of 15.1 pints/acre (5.5 fl oz/1000 sq. ft) of HMO-1601 (11.3 lb a.i./acre). 
Application must be made before snow cover in autum n. 
 
Group B Turf: If snow cover is intermittent or lacking during the winter, a second application of HMO-
1601 at 15.1 pints/acre (5.5 fl oz/1000 sq. ft) may be applied one month after the first application. 
 
Pink Snow Mold, Microdochium Patch caused by Microdochium nivale : 
 
Group A and B Turf: In areas where pink snow mold is likely to occur, apply HMO-1601 at 15.1 
pints/acre (5.5 fl oz/1000 sq. ft) (11.3 lb a.i./acre) in combination with products containing iprodione at 88 
oz a.i./acre (2 oz a.i./1000 sq ft) of turf area. Read and observe all label directions for products c ontaining 
these active ingredients. For control of Microdochium patch only in areas where snow cover is intermit tent 
or lacking during the winter, apply 15.1 pints/acre (5.5 fl oz/1000 sq. ft) of HMO-1601 (11.3 lb a.i./acre). 
Make application in late autumn. 
 
Group B Turf: Apply a second application of 15.1 pints/acre (5.5 fl oz/1000 sq. ft) of HMO-1601 21 to 28 
days after the first application unless conditions favorable for disease development no longer prevail. 
 
Algae: 
 
Group A and B Turf: For prevention of algae on turfgrasses, apply HMO-1601 at the rate of 5.5 to 9.75 
pints/acre (2.0 to 3.6 fl oz/1000 sq. ft) (4.1 to 7.3 lb a.i./acre) on a 7- to 14-day schedule. Under severe 
algae conditions use the 9.75 pints/acre (3.6 fl oz/1000 sq. ft) rate and apply on a 7-day schedule.

When algae is well established, every attempt should be made to dry out the afflicted area. Once dry, 
spiking or verticutting should be done to enhance turfgrass recovery in conjunction with a HMO-1601 
application at the rate of 11 to 15.1 pints/acre (4.0 to 5.5 fl oz/1000 sq. ft). 
 
Group B Turf: A second application of HMO-1601 at the 15.1 pints/acre (5.5 fl oz/1000 sq. ft) rate may 
be made 14 days after the first application. 
 
Group A and B Turf: Following application of the 15.1 pints/acre (5.5 fl oz/1000 sq. ft) rate, several 
applications of HMO-1601 at a rate of 5.5 to 9.75 pints/acre (2.0 to 3.6 fl oz/1000 sq. ft) (4.1 to 7.3 lb 
a.i./acre) on a 7-to 14-day interval may be necessary for turfgrass recovery. Only a preventive spray 
program with HMO-1601 will prevent a recurrence of the algae when environmental conditions are 
favorable. 
 
ORNAMENTAL PLANTS 
 
Apply HMO-1601 at a rate of 1 3/8 pints (1.0 lb a.i.) per 100 gallons of water unless other directions are 
given in the tables below. 
 
DO NOT apply more than 48.5 pints HMO-1601 (36.4 lb a.i./acre) per growing season to field-grown 
ornamentals. 
 
HMO-1601 should be applied to plants when both foliage and flowers are dry, or nearly dry. 
 
Apply in a spray to run-off when conditions are favorable for disease development. Repeat applications at 
7 to 14 day intervals until conditions are no longer favorable. During periods when conditions favor severe 
disease incidence, generally cloudy or wet weather, apply HMO-1601 at 7 day intervals. 
The minimum re-treatment interval is 7 days. 
DO NOT combine HMO-1601 in the spray tank with pest icides, surfactants or fertilizers, unless your prior 
use has shown the combination to be physically comp atible, effective and non-injurious under your 
conditions of use. 
 
HMO-1601 may be used in greenhouses. DO NOT use mis t blowers or high pressure spray equipment 
when making applications of HMO-1601 in greenhouses . 
 
Knock Out® and Double Delight roses can be sensitiv e to HMO-1601 applications, resulting in damage to 
foliage under certain growing conditions. 
 
Use of HMO-1601 is recommended for control of funga l diseases referred to by numbers in parentheses 
following each ornamental. Ornamentals listed on th is label have been tested and found to tolerate 
applications of HMO-1601 at the recommended rates. The user should test for possible phytotoxic 
responses, using recommended rates on ornamental pl ants on a small area prior to commercial use. 
Applications made during bloom may damage flowers a nd/or fruits.
