) ( ) -4- 5 FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN CROP INJURY. POOR DISEASE CONTROL. OR ILLE­ GAL RES !DUES. General Information Ridomil 50W is a systemic fungicide for use on selected crops to control certain diseases caused by members of the Oomycete class of fungi. Other fungicides must be used to control diseases incited by other classes of fungi. THIS PRODUCT IS NOT TO BE USED IN FOLIAR APPLICATIONS UNLESS SPECIFIED ON THIS LABEL OR IN SOLUTIONS USED TO DIP PLANTS. DO NOT USE IN NURSERIES. TURF. OR LANDSCAPE PLANTINGS UNLESS SPECI­ FIED IN THIS LABEL. : Ridomil is a systemic fungicide having a specific mode of action and could be subject to development of in­ sensitive strains of fungi. Development of insensitivity cannot be predicted. Therefore, Ciba-Geigy cannot assume liability for crop damage resulting from insensitive strain of fungi. If treatment is not effective following the use of Ridomil as recommended, an insensitive strain of fungi may be present. If the treatment is ineffective due to the presence of a Ridomil insensitive strain of fungi, neither Ridomil nor any other fungicide with similar action will effectively control that disease. Consideration should then be given to the prompt use of othr tyPp.s of suitable fungicides. Consult with your State Agricultural Experiment Station or Extension Service Specialist for guidance on your particular crop and disease control situ­ ation. Do not make foliar applications to field grown tobacco, or other crops unless specified since this practice may en­ courage more rapid development of insensitivity. THIS LABEL IS FOR FIELD USE ONLY AND IS NOT INTENDED FOR USE ON TRANSPLANT TRAYS. GREENHOUSES, LATH HOUSES. OR IN BEDDING PLANT STRUCTURES. Where rate ranges are specified on this label, use the highr. rate when heavy disease pressure is expected and the lower . rate when disease pressure is expected to be light unless otherw i se noted. ., .. ,. To avoid spray drift, do not apply under windy conditions. Avoid spray overlRp, as rrop injury may result. . , . . 37 . , .... , , . ., , .

\ 1 -5- Mixing Instructions Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean spray equipment before using this product. Vigorous agitation is necessary to maintain uniformity of the spray mixture. Maintain maximum agitation throughout the spraying operation. Do not let the spray mixture stand over­ night in the spray tank. Flush the spray equipment thoroughly following each use and apply the rinsate to a previously treated area. Precautions: (1) water soluble bags of Ridomil SOW must be com­ pletely dissolved and dispersed in plain water before any other tank mix partner, including micronutrients or other liquid or dry fertilizers, are added to the spray solution. Boron, espe­ cially in the form of a micronutrient additive, such as 'Solubor®, etc., or as a natural component of the mix water, may prevent water soluble bags from dissolving. (2) When the spray carrier is primarily composed of liquid fertilizers (e.g., 10-34-0 or 9-18-9) soluble bags of Ridomil SOW ~ be slurried in water following the procedre as outlined in Ridomi1 50W in Liquid Fertilizer. Ridomil SOW Aloke: Add 2/3 of the required amount of plain water to the spray or mixing tank. With the agitator running, drop the required number of unopened soluble bags of Ridomil 50W into the lank all at once. Continue agitation while adding the remainder of tht water. Begin application of the spray solution after the bags have dissolved and the material has completely dispersed into the mix water. Maintain agitation until all of the mixture has been applied. BEFORE TANK MIXING RIDOMIL 50W WITH OTHER REGISTERED PRODUCTS FOR ANY USE ON THIS LABEL. REAP THE LABEL OF THE TANK MIX PART­ NER TO BE CERT IT IS LABELED FOR USE ON THE PARTICULAR CROP AND THAT SE PATTERNS ABE :OMPATIBLE WITH THOSE OF RIDOMIL 50W. Ridomil 50W + Tank Mixtures: Ridomil 50W is usually compatible with most commonly used insecticides, fungicides, and spray adjuvants. When using Ridomil SOW in a tank mixture with other pesticides, observe the most restrictive label limitations and precautions of the products being used. Add 2/3 of the required amount of plain water to the spray Gr mixing tank. With the agitator running, drop the required I.um­ ber of unopene soluble bags of Ridomil SOW into the tank aj~ a~ once. Continue agitation while adding the remainder of the water. Allow the bags of Ridomil SOW to dissolve and the prod~ uct to completely disperse into the mix water. Then add th~"':' desired amount of other products recommended for tank mixtup. • and allow them to become completely dispersed. Continue agjtA' tion to maintain a uniform suspension until all of the spray solution has been applied. , )

) -6- Ridomil SOW in Liquid Fertilizex: Slurry Ridomil SOW in water. Add a maximum of 4 unopened soluble bags of Ridomil SOW to S gallons of clean water. Stir the solution until all of the soluble bag material has dissolved and the Ridomil SOW has formed a smooth slurry. Add 2/3 of the required amount of water and/or liquid fertilizer to the spray or mixing tank. With the agitator running, add the Ridomil SOW slurry. If adding other tank mix partners, add the products in the following order: Ridomil SOW slurry, wettable powders or dispersible granul~=, and then emulsifiable concen­ trates. Allow each product to disperse before adding the next one, maintaining agitation the whole time. Triple rinse the slurry container and add to the spray tank. Add the remainder of the water and/or fertilizer and continue agitation. Maintain agitation until all of the mixture has been applied. APplication Instructions Apply Ridomil SOW by ground or air in sufficient water to provide uniform coverage of the soil surface. Apply in a mini­ mum of 20 gals.fA for ground applications and S gals./A by air. Refer to the specific crop directions for use for application recommendations. For banded applications, the area actually is the area covered by the band, not total cropland area planted. Some row-crop recommendations are based on treating in-the-row and these rates generally are specified as amounts of product per certain row length (often 1,000 ft.). Others express rates as amount pe~ treated acre which means the total area treated wi~h the pesti­ cide. If rates are expresged as amount per treated a~~e and banded applications are used, the amount of pesticide used per acre will be proportionately less. The following formula can be used to calculate the amount of Ridomil SOW needed per acre of crop when banded applications are made: band width in inches broadcast rate amount needed row spacing in inches X per acre = ger acre of field Application Through Irrigation Systems Ridomil SOW, alone or in combination with other fungicides which are registered for sprinkler irrigation, may be applied through irrigation systems. Apply this product only through center pivot, solid set, hand­ move, moving wheel, micro-sprinkler, or drip irrigation systems. Do not apply this product through any other type of irrigation system. Crop injury, lack of effectivpness, or illegal pesti­ cide residues in the crop can result from non-uniform distribution of treated water. If yOU have questions aoout calibration, you should c"ntact State Extension Service special- 37 i 7

j I -7- ists, equipment manufacturers, or other experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the pesti­ cide label"prescribed safety devices for public water systems are in place. A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make nec­ essary adjustments should the need arise. Operating Instructions

1. The system must contain a functional che,::k-valve, vacuum relief valve, and low pressure drain appropriately located on the irrigcotion pipeline to prevent water-source contamination from backflow.
2. 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.
3. The pesticide injection pipeline must also contain a func­ tional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
4. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
5. The irrigation line or water pump must include a func­ tional pressure switch which will stop the water pump motor whe~ the water pressure decreases to the point where pesticide distribution is adversely affected.
6. Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effec­ tively designed and ccnstructed of materials that are com­ patible with pesticides and capable of being fitted with a system interlock.
7. Do not apply when wind speed favors drift beyond the area intended for treatment. Ap~lication Instructions Ridomil SOW must be applied on the schedule specified in the specific crop use recommendations, not according to the irriga­ tion schedule. If irrigation schedules are used, ground or aerial applications must supplement chemigation applications to achieve adequate disease control. The f0110wing calibration and application techniques are pro­ vided for user reference, but do not constitute a warranty of 37

Users should check with state and local regulatory agencies for potential use restrictions before applying any agricultural chemical through sprinkler irrigation equipment. Center Pivot Irrigation Equipment Note: (1) Use only with drive systems which provide uniform distribution. (2) Do not use end guns when chemigating Ridomil 50W through center pivot systems because of non-uniform applica­ tion. I . 2 . 3 . 4 . S . Determine the size of the area to be treated. Determine the time required to apply 1/4-1/2 inch water over t~e area to be treated when the system and injection equipment are operated at ormal pressures as recommended by the equipment manufac~~rer. Run the system at 80-95% of the manufacturer's rated capacity. Using water, determine the injection pump output when operated at lormal line pressure. Determine the amount of Ridomil 50W required to treat the area covered by the irrigation system. Add the required number of Ridomil 50W soluble bags and sufficient water to meet the injection time requirements to the solution tank. (See Mixing Instrctions section of this label.) 6. Make sure the system is fully charged with water before starting injection of the Ridomil 50W solution. Time the injection to last at least as long as it takes to bring the system to full pressure. 7. 8. Maintain constant solution tank agitation during the injection period .

Continue to operate the system under the Ridomil SOW solution has cleared the last sprinkler head. Micro Sprinkler or Drip Irrigation Systems General Instructions Each run of the irrigation system must be calibrated sepa­ rately to determine the time it takes water to move through the system and to make sure all emitters in the system are putting out the same amount of water. Only pressure injection or venturi equipment is recommended. Determine the area to be treated in eaCL irrigation run. Measure the output of each of the emitters or drip tubes closest to and farthest from the injector site. Fo~ calibration, SUbstitute a concentrated det~rgent (such as Wisk) for the Ridomil SOW in the injector tank. It is important to use the same volume of soap solution as the planned volume of Ridomil 50W solution when calibrating the syystem. The detergent will bubble as it leaves the emit­ ters. The time period 0ver which bubbles occur should be checked for both the closest and farthest emitters. If these times are not within 2 minutes of each other, adjust the dilution ratio and/or the injection rate. ~p-by-Step Instructions Before starting to calibrate, operate the system until all the emitters are putting out at equal flow rates or until the system is operating at full pressure. Make up an indicator solution of detergent or fertilizer using the same ratio to be used with mixing Fidomil SOw. Set the injector to apply the indicator solution at the injection rate to be used in the actual Ridomil SOw ~pplica­ tion. Attach a 5-inch length of flexible tUbing over the emitter closest to the injection point, another length over the 1 37 /0

. • -10- fl

emitter farthest away. Both emitters should be monitored to

determine the time intervals that the indicator solutions

are observed.

Begin injecting the indicator solution. Direct the flow

from the tubes at the emitters into a small container.

Begin timing when the indicator solution is first detected,

stop timing when the indicator solutions are no longer

detected.

If the period of detection of the indicator solution

between the 2 emitters are within 2 minutes of each other,

comparable coverage will be obtained. If they are not, make

adjustments by increasing the dilution ratio, using more

water per part of Ridomil SOW, or adjust the injector to a

slower flow rate.

Once the system is calibrated, dilute the needed amount of

Ridomil SOW with water using a minimum of 10 parts water to

1 part Ridomil SOW.

Do not begin to inject Ridomil SOW into the system until all

emitters are producing equal flow rates, or until the system

is at full pressure.

Inject the Ridomil SOW into the system at the end of the

irrigation set in 1/2 - 1 inch of irrigation water.

Note: Do not apply Ridomil SOW within 1 day of harvest or pos­ sible illegal residues may result. Ayocados Root Rot - Phytophthora cinnamomi Begin applications at the start of the growing seson or at transplanting. Two additional applications should be made at 3-month intervals. Applications are not needed during the win­ ter months of November through February. Ridomil SOW may be applied as a sleeve drench at the time of transplanting, as a soil surface spray under sprinkler irrigation systems, as a directed spray under drip emitters, or injected into the irriga­ tion water. Sleeve Drench: Mix 1/2 oz. of Ridomil SOW with 18 gals. of water. At the time of transplanting, drench the roots inside the sleeve with 1 qt. of Ridomil SOW solution per tree. e. The sleeve drench will not replace the soil surface applications for long-term control of root rot. Sprinkler Irrigation: Apply as a soil surface spray under the canopy of the tree in sufficient water to obtain uniform cover­ age. See the following table for the amount of Ridomil SOW to use based on the diameter of the tree canopy. Start applica­ tions 2-t the beginning of the growing season or at transplanting and continue at 3-month intervals. Drip IrrigatiQD: Apply the recommended amount of Ridomil SOW (see table) to the soil directly under the drip emitter at each tree. If there is more than one emitter per tree, distribute the total amount of Ridomil SOW needed among the emitters. Injection into Irrigation Water (Sprinkler or Drip Irrigation Only): Inject Ridomil SOW into the irrigation water at a rate of 1-2 oz./l,OOO gals. (3 3/4-7 1/2 ppm active ingredient) at each irrigation. If Ridomil SOW is not appled at each irrigation, use the following table to determine how much Ridomil SOw should be injected into the irrigation water. If Ridomil SOW is to be used more frequently than every 3 months, adjust the rates so that no more than the specified amount is applied during each 3-month period.

NQLe: For best control of blue mold, use Ridomil SOW in the plant bed and follow with an application in the field prior to transplanting. Do not use Ridomil SOW in transpla.lt water on field tobacco because of the potential for crop injury. Do not use Ridomil SOW as a foliar spray to field planted tobacco. Black Shank: Use Ridomil SOW as a broadcast soil application anrl inorpo[ate in the top 2-4 inches of soil before forming beds. Apply Ridomil SOW using conventional ground application ~r!Ulpment in sufficient water to provide uniform coverage. Use

• " -29- the following table to determine the amount of Ridomil SOW needed per acre depending on the black shank severity. Type of Tobacco Flue-Cured Burley and Other·· Disease Level in Field Low to moderate (Less than 6% Disease) High (More than 6% Disease) Low to moderate (Less than 6% Disease) High (More than 6% Disease) Rate of Ridomil SOW Per Acre 2 lbs. 4 lbs.* 4 lbs. 6 lbs. *FL and GA - Use 6 lbs./treated acre of Ridomil SOW in fields with heavy black shank levels (greater than 6%). **PA - Do not use Ridomil SOW for black shank control. For longed control of black shank in field planted tobacco, QUe of the following is recommended: (1) Make a preplant incorporated and a supplemental lay-by application (last cultivation). Apply the supplemental application at last cultivation at the rate of 1-2 Ibs./A as a soil treatment. position the nozzles so that the spray is dposited under the plants and is covered with soil by the cultivator. Do not make this application if more than 2 lbs./A of Ridomil SOW was applied at transplanting; or (2\ Make a preplant incorporated plus two supplemental applications at first cultivation and last cultivation (lay-by). Apply Ridomil SOW at 2 lbs./A just prior to transplanting followed by a second application of 2 Ibs./A at the first cultivation followed by a third application of 2 lbs./A at lay-by or the last cultivation. £recautions: (II For best results against black shank. use RidQffiil.~W with tobacco varieties that have some resistance to bl.QclL,<;;,ha!)~ll';tJ.lse crop rotation.

(3) Failure to adequately control nematodes in fields treated with Ridomil SOW may result in poor control of black shan~ No-till Tobacco: Apply Ridomil SOW to the field before t=ans­ planting for control of black shank and blue mold on all types of tobacco. Apply 1-2 Ibs./treated acre as a preplant, broad­ cast, or banded soil application. For banded applications, use the formula in the General Information section of this label to calculate the amount of Ridomil SOW needed per acre. A supple­ mental lay-by application may be made 30-35 days after planting at 1 Ib./A. Do not make the lay-by application if more than 2 Ibs./A of Ridomil SOW were applied at transplanting or if no Ridomil SOW was applied at transplanting. Tomatoe3 1 ) Soil applications of Ridomil SOw at planting will provide con­ trol of damping-off caused by fythium spp. Soil applications applied 4-12 weeks before harvest under the vines will control fruit and root rot caused by pythium spp. and Phytophthora spp. Damping-Off IPythium spp.): Apply 2-4 Ibs./treated acre in suf­ ficient water to provide uniform coverage at the time of plant­ ing. If rainfall is not expected before the seeds start to germinate, Ridomil SOW should be incorporated mechnJ ically before planting, during the planting operation, or be moved into the seed zone after planting with 1/2 - 1 inch sprinkler irriga­ tion. For banded applications, a 7-inch band is recommended. Use the formula in the General Information section of this label to calculate the amount of Ridomil SOW needed per acre. Root and Fruit Rot IPhytophthora spp and pythium spp.) To aid in the control of root and fruit rot, 1 or 2 additional applications may be made during the growing season, depending on the severity of the conditions for disease infection. Apply 2 Ibs./treated acre beginning 4-6 weeks after planting. A second application may be made as needed up to 4 weeks before harvest, but before the last irrigation. Ridomil SOW may be applied as a directed soil surface spray under the vines or it may be injected into the beds. If less than the full bed is treated, ue the formula in the General Information section to determine ti'2 amount of Ridomil SOW needed per acre. If Ri1o:nil SOW is injected into the beds, base calculations on a 7-inch band. If soil surface sprays are used, the R1domi1 SOW must be incor­ porate into the soil with 1/2 - 1 inch of rainfall or sprinkler irrirJat ion. 37 ~(

(3) Do not use Ridomil SOW for dis­ ease control in greenhouse crops or vegetable bedding plants. Replanting If replanting is necessary, additional applications of Ridomil SOW may be made, provided that the total amount of metalaxyl applied does not excee1 the maximum allowed for the specific crop. -tI'. /1
