GENERAL INSTRUCTIONS AND INFORMATION 
Boa is a contact herbicide used to control or suppress a broad spectrum of emerged weeds. Boa controls most 
small annual weeds--both broadleaves and grasses, and suppresses perennial weeds by destroying green foliage. 
Boa can also be used as a crop desiccant at harvest. 
Boa is formulated as a liquid which contains 2'12 pounds of active ingredient per gallon. The formulation is 
green in color and contains a nontoxic odor, and an emetic (an agent which will induce vomiting if the product 
is swallowed). The green color and odor are included in the formulation to help prevent accidental ingestion of 
Boa. 
Boa is rapidly absorbed by green plant tissue and interacts with the photosynthetic process to produce 
superoxides which destroy the plant cells. Boa requires actively growing green plant tissue to function. 
Thorough coverage of all green foliage is essential for effective weed control. Boa is not as effective on drought 
stressed weeds, weeds with little green foliage (i.e. mowed or cut weeds), or mature woody bark of trees and 
Griffin L.L.c. EPA Reg. No 1812·420 Filenamel812·420 Boa USA 09120lamendment Date 091201 Page 4 of 43

• .. 5 ;- 7'3 vmes. 
Clay and organic matter rapidly tie up Boa. As a result, Boa has no residual soil activity to affect late-planted 
crops or later-germinating weeds. 
Do not apply this product through any type of irrigation system. 
When Boa is applied at less than 10 gallons per acre finished spray volume, a drift control or spray deposition 
additive SHOULD be used. Refer to the additive label for use directions. 
AERIAL DRIFT REDUCTION ADVISORY INFORMATION 
A voiding 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 off-target drift movement from aerial 
applications to agricultural field crops. These requirements do not apply to forestry applications, public health 
uses or to applications using dry formulations. 
I. The distance of the outer most nozzles on the boom must not exceed % the length of the wingspan or 
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 shall be observed. 
The applicator should be familiar with and take into account the information covered in the Aerial Drift 
Reduction Advisory Information. 
INFORMATION ON DROPLET SIZE 
he 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 environmental 
conditions (see Wind, Temperature and Humidity, and Temperature Inversions). 
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 recommended 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 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 nozzle type that is designed for the intended application. With most nozzle types,

• • G l- '13 
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. 
BOOM LENGTH 
For some use patterns, reducing the effective boom length to less than '14 of the wingspan or rotor length may 
further reduce drift without reducing swath width. 
APPLICATION HEIGHT 
Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a 
greater height is required for aircraft safety. Making application 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 up 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 drift potential (higher wind, smaller 
drops, etc.). 
WIND 
Drift potential is lowest between wind speeds of2 to 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 application 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. Temperature 
inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated 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 movement of smoke from a ground source or an aircraft 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 potential for drift to adjacent sensitive areas (e.g. residential 
areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g. 
when wind is blowing away from the sensitive areas).

ROTATIONAL CROPS 
All rotation crops may be planted immediately after the last application of Boa. 
RAINFASTNESS 
Because Boa is rapidly absorbed by the weed foliage, rain occurring 30 minutes or more after application will 
have no effect on the activity of Boa 
APPLICATION 
Since Boa is a contact-type herbicide, it is essential to obtain complete coverage of target weeds to get good 
control. Improper application technique and/or application to large, stressed, or mown weeds will usually result 
in unacceptable weed control. Good coverage is also essential for proper performance in harvest-aid 
applications. See details below for specific application instructions. 
USE A NONIONIC SURF ACT ANT OR CROP OIL CONCENTRATE 
ALWAYS ADD ONE OF THE FOLLOWING: 
Failure to add one of the following will result in reduced performance of Boa herbicide. 
Nonionic Surfactant: Add nonionic surfactant containing 75% or more surface-active agent at 0.125% v/v (l 
pint per tOO"galions) OR add a nonionic surfactant containing 50% to 74% surface-active agent at 0.25% v/v (2 
pints per tOO gallons), of the finished spray volume for ground applications. For aerial applications, add a 
nonionic surfactant at 0.25% v/v (2 pints per 100 gallons) of the finished spray volume 
Crop Oil Concentrate: Add a nonphytotoxic crop oil concentrate containing 15% to 20% approved emulsifier, 
at 1.0% v/v (1 gallon per 100 gallons) of the finished spray volume for ground applications. For aerial 
applications, add 1 pint of crop oil concentrate per acre. Do not use crop oil concentration when using Boa for 
"ot\on harvest aid. 
NOZZLE SELECTION 
The use of flat-fan nozzles will result in the most effective application of Boa herbicide. Flood nozzles are 
generally not as good as flat fans since they produce large uneven droplets. The use of flood nozzles may result 
in reduced weed control due to inadequate coverage. 
WHEN SPRAYING LESS THAN 20 GALLONS OF SPRAY CARRIER PER ACRE, USE ONL Y FLAT­
FAN NOZZLES AS RECOMMENDED IN THE CHART BELOW.

Maximum Speed 10 mph 10mph 
Spray overlap (at each edge) 30% 50% 
Using nozzles, pressures or setups different from the above chart will result in reduced control. 
SPRAY CARRIER 
Always use clean water (free of mud or clay), clear liquid nitrogen, or complete clear liquid fertilizers as the 
carrier when spraying Boa herbicide. Muddy water, or suspension-type fertilizers containing clay, can inactivate 
Boa. Never use suspension-type fertilizers containing clay as the spray carrier. If using a complete clear liquid 
fertilizer containing high phosphate levels as the spray carrier, always use the higher rate of Boa and surfactant. 
NOTE: When using liquid fertilizers such as 28% N as a carrier, it is important that nonionic surfactant still be 
used with Boa herbicide. Liquid fertilizer carriers cannot substitute for surfactant. 
RATES OF Boa 
Follow recommended rates listed with each use of Boa herbicide. Use the high label rates when weeds are dense 
or large. Also, use higher label rates for harvest aid when crop vegetation is dense.For broadcast applications of 
Boa with backpack sprayers, the application rate should not exceed 0.50 pounds ail A in a minimum of 30 
gallons of spray solution per acre. 
SPRAY VOLUME 
Follow recommended minimum spray volumes listed with each use of Boa herbicide. These are minimum 
volumes only, and spray volumes should be increased as necessary to obtain complete coverage of the target 
weed or plant without runoff from the foliage. 
WHEN SPRAYING LESS THAN 20 GALLONS OF SPRAY CARRIER PER ACRE, TARGET WEEDS 
SHOULD NOT EXCEED 6 INCHES IN HEIGHT. 
-\PPLICATION TIMING 
Boa should be applied to emerged weeds when they are small. Weeds 1 inch to 6 inches in height are the 
easiest to control. Larger weeds may be more difficult to control. When weeds have been grazed or mowed, 
thus removing much of the green foliage, allow the weeds to regrow to a height of 2 to 4 inches before spraying 
if possible. Similarly, when forage or grain crops have been harvested prior to spraying, weeds present in the 
field will also have been cut. To allow for adequate green foliage to remain on weeds in this situation, raise 
cutter bars as high as possible from the ground to cut stubble and weeds at a greater height. 
BURNDOWN OF GRASS COVER CROPS OR VOLUNTEER CEREALS 
When using Boa for control of grass cover crops or volunteer cereals, best results are obtained when Boa is 
applied prior to tillering or after boot stage. This is especially important with a wheat cover crop or volunteer 
wheat. Treatments made between tillering and boot stage will generally not provide complete control. Do not 
expect complete control of perennial cover crops.

• • 
Boa is active over a wide range of envirorunental conditions. Cool weather (below 55°F) will slow the activity 
of Boa, as will cloudy, overcast weather, but will not affect performance. 
SPOT SPRAYING 
When only small areas are to be sprayed with labeled applications, it is advantageous to mix small quantities of 
Boa herbicide. To aid in mixing small quantities, the following table should be consulted. 
If the Broadcast rate per acre for Boa herbicide is: Add the Following Amount of 
Boa Herbicide to 1 Gallon 
of Water 
1 \I, pints 113 fl. oz. 
2 pints 3/8 fl. oz. 
2\1, pints \I, fl. oz 
3 pints 2/3 fl. oz. 
Always add 113 to 'h fluid ounce of a nonionic surfactant for each gallon of spray. When spot spraying in this 
manner, spray to thoroughly wet the foliage, but not to the point of runoff. 
TANK MIXING FOR IMPROVED BURNDOWN OF DIFFICULT WEEDS AND RESIDUAL WEED 
CONTROL 
Photosynthetic Inhibitor Herbicides 
Difficult weeds can often be controlled by tank mixing Boa with other herbicides. The addition of herbicides 
which are also photosynthetic inhibitors (PSI) will slow the activity of Boa, allowing Boa to thoroughly 
distribute itself within the treated leaf. The resulting level of control is usually greater than if Boa was applied 
alone. 
Joa herbicide may be applied in tank mixture PSI herbicides including the following: 
.. 
AatreX®, Atrazine, Bicep®, Bicep Lite®, Canopy®, Direx® 4L, Gemini®, Karmex DF, Lariat®, Lexone®, LineX® 
4L, Lorox®, PrevieW®, Princep® and Sencor®. 
Refer to respective product label(s) for rates of application, directions for use, limitations, precautions, and a list 
of weeds controlled. 
Improved Weed Control with PSI's 
Control of difficult weeds listed below and annual grass control will be enhanced by the addition of a PSI 
herbicide. For best results a second application is needed. 
Marestail, Pennsylvania Smartweed, Velvetleaf, Malva (Cheeseweed), Fall Panicum, Giant Ragweed, Kochia, 
Cocklebur, Tansymustard, Prickly Lettuce, Lambsquarter, Momingglory, Cheatgrass, Knotweed, Volunteer 
Wheat, Perennial Weeds (suppression only), Barnyardgrass, Broadleaf Signalgrass and Sedges.

When perennial broadleafweeds such as Canada thistle, bindweed, dandelion, etc., or difficult to control annual 
broadleaf weeds such as giant ragweed or momingglory are present, tank mixes with 2,4-0 ester (Low Volitile), 
2,4-0F or Banvel®, where labeled, will help improve control. Tank mixing the amine formulation of 2,4-0 with 
Boa may result in reduced grass control. 
Order of Tank Mixing 
In general, Boa tank mixes with other products should be mixed as follows: 
I. Fill spray tank V. full with clean water or other approved carriers such as clear liquid fertilizer. 
2. Begin tank agitation and continue throughout mixing and spraying. 
3. Add dry formulations (WP, OF, etc.) to tank. 
4. Add liquid formulations (SC, EC, L, etc.) to tank. 
5. Add Boa to tank. 
6. Add nonionic surfactant to tank. 
7. Fill remainder of spray tank. 
Always refer to labels of other pesticide products for mixing directions and precautions which may differ from 
those outlined here. 
Since many of the herbicides listed on this label are available in several types offormulations, it is advisable to 
perform a jar test to check physical compatibility. 
GENERAL PRECAUTIONS AND RESTRICTIONS 
EQUIPMENT/CONTAINER: Flush all spray equipment with water after use each day. Boa is corrosive to 
aluminum. Aluminum spray equipment and aluminum aircraft structures that are exposed to spray solution or 
spray drift should be flushed thoroughly with water immediately after use. 
In dry areas, dust stirred up by high winds or equipment tires can coat weed leaves and reduce Boa activity. 
I\void applying Boa in extremely dusty conditions. 
LIMIT A TIONS, PRECAUTIONS AND WARNINGS 
• Do not use around home gardens, schools, recreational parks or playgrounds. 
• In preplant and preemergence (to the crop) uses, do not apply to soils lacking clay minerals, i.e., peat, muck, 
pure sand, artificial planting media. 
• Seedbeds and plantbeds should be formed as far ahead of planting and treatment as possible to permit 
maximum weed and grass emergence prior to treatment. 
• Seeding or transplanting should be done with a minimum amount of soil disturbance. 
• Boa used for preplant weed control over the top of plastic mulch may damage transplants which come in 
contact with the plastic. Sufficient rainfall or sprinkler irrigation to cause wash-off prior to planting may be 
needed to prevent damage to the crop. 
• Weeds and grasses emerging after application of Boa will not be controlled or suppressed. 
• Unless otherwise indicated, crop plants emerged at time of application may be severely injured or killed if 
contacted by sprays of Boa.

RESIN SOAKING 
Pines (Loblolly, Shortleaf, Longleaf, Slash, Virginia, Pond, Pitch, and Spruce Pines). 
Tree Selection - Select trees to be treated from stands on sites not subject to periods of extreme drought stress as the 
desiccating effect of Boa to pines is accentuated during such periods, causing a reduction in the amount of oleoresin 
deposited in the xylem. Select trees to be treated from vigorous, non-stagnated stands, either natural or planted. In 
stagnated stands or commercial timber stands, plan treating with Boa herbicide not sooner than three years after a 
commercial thinning. 
Application Directions - Apply Boa diluted in water to a suitable wound in the tree trunk to bring the treatment into 
contact with the xylem (sapwood). 
Bark Streaks or Cuts: This type of wound is made using a standard or rotary bark hack or a chainsaw chipping tool 
employed in naval stores work to remove a single one-inch wide streak of bark about 1 to 2 feet from the ground level. The 
total length should not exceed 1/3 of the tree circumference. Multiple streaks or cuts can result in serious girdling of the 
trunk and premature death of the tree. A course spray (about 2 to 6 mI.) of Boa solution (1 % to 5 % cation, wt.lwt. basis) 
Griffin L.L.C. EPA Reg. No 1812-420 Filename1812-420 Boa USA 09120lamendment Date 091201 Page 37 of43

depends on tree circumference and the length of cut or streak (1/3 of circumference). For a 9-inch diameter tree, 3 ml. Of 
spray will cover the 1-inch wide streak. Using 3 ml. Of a 2 % or 4 % Boa solution will result in application of 60 or 120 mg 
Boa per streak. 
Time of Treatment: Resin soaking can occur from treatments made any time of the year; however, cool season 
treatments under nondrought conditions usually result in less severe pine beetle infestations and longer tree life. 
Interval Between Treatment and Tree Harvest: The interval between application of Boa and tree harvest should be a 
minimum of 6 months and preferably from 12 to 24 months. Intervals of over 6 months may not be possible under 
conditions of drought or serious pine beetle attacks, which may make early harvest necessary. The Boa treatment may 
encourage beetle attack. Or may cause premature death of the tree. Desiccation of the xylem tissue, rather than the 
desired resin soaking, may occur, and is more likely at higher dosage rates. 
Effect On Stem Growth: 
Boa herbicide treatment can result in reduced stem growth during the interval between treatment and tree harvest.
