DuPont TRIVENCE herbicide is a dispersible granule formulation to be mixed with water and sprayed for selective burndown plus residual weed control in soybeans. When applied according to the instructions on this label, it will control many broadleaf weeds and provide partial control of nutsedge and annual grasses. Crop injury may occur from applications made to poorly drained soils under cool, wet conditions. Risk of crop injury can be minimized by not using on poorly drained soils, planting at least 1.5 inches deep and completely covering seeds with soil prior to preemergence applications.
Residual control from TRIVENCE requires rainfall or sprinkler irrigation to activate the herbicide. Degree of control and duration of effect depend on: rate used, weed spectrum, growing conditions at and following time of treatment, soil pH, texture, organic matter, moisture and precipitation.
Best residual control is obtained if TRIVENCE is applied to moist soil and followed by rainfall or irrigation (~1”) before weeds germinate. Several small rainfalls of less than 1/4” each are not as beneficial as one large rainfall of 1/2-1”. On dry soil, more moisture is required for activation (1-2”) before weed emergence. If moisture is insufficient to activate the herbicide, a rotary hoeing or shallow cultivation should be made after emergence of the crop while weeds are small enough to be controlled by mechanical means. Deep cultivation reduces the effectiveness of TRIVENCE and should be avoided.

Do not exceed 6.0 oz/acre per crop season north of State Road 46 in the state of Michigan.
Do not exceed 9.0 oz/acre TRIVENCE on soils with a composite pH greater than 7.0 in the Southern Region.
Do not apply to Black Belt Soils of Alabama and Mississippi with a soil pH greater than 7.0 or history of nutrient deficiency such as iron chlorosis, as injury may occur.
Do not apply TRIVENCE to cracking soybeans or after the soybean crop has emerged as severe injury or death of the crop will occur.
Do not irrigate when soybeans are cracking.
Do not apply TRIVENCE within 14 days before or after an application of an organophosphate insecticide on any soybean variety that is not DuPont STS, STS/RR or soybeans with BOLT technology, as severe crop injury may occur.
Do not apply this product by air within 40 feet of nontarget plants including non-target crops.
Do not apply this product by air within 100 ft. of emerged cotton crops.
Do not apply this product by air within 40 feet of streams, wetlands, marshes, ponds, lakes and reservoirs.
Do not apply by air during a temperature inversion, when wind speed is less than 2 mph or above 10 mph, or when other conditions
could produce poor coverage and/or off-target spray movement.
Do not apply TRIVENCE by air in the state of New York.
Do not apply to land that has been or will be treated with metsulfuron and/or chlorsulfuron-containing herbicides in Nebraska and Kansas without observing the rotational crop intervals for those products.
Do not apply or drain or flush equipment on or near desirable trees or other plants, or on areas where their roots may extend, or in
locations where the chemical may be washed or moved into contact with their roots, or injury to desirable trees and plants may occur.
Do not use on lawns, walks, driveways, tennis courts or similar areas.
Do not contaminate any body of water.
Do not mix/load, or use within 50 feet of all wells including abandoned wells, drainage wells, and sink holes.
Do not apply this product when weather conditions favor spray drift from treated areas.
Do not discharge excess material on the soil at a single spot in the field or mixing/loading station. Graze treated fields or feed treated forage to livestock no sooner than 40 days after application.
Do not use low pressure and high volume hand wand equipment.
Use only in the geographies identified in the "Geographic Use Regions" section of this label.
IMPORTANT USE PRECAUTIONS
Prior to using TRIVENCE herbicide, consideration should be given to crop rotation plans. Crops other than soybeans may be extremely sensitive to low concentrations of TRIVENCE remaining in the soil the next planting season. Choice of rotation crop is restricted following application of TRIVENCE. (See "ROTATIONAL CROP GUIDELINES" for your geographical region). Crop injury may occur from applications made to poorly drained soils under cool, wet conditions. Crop injury may occur if TRIVENCE is used on soils with a history of nutrient deficiency, such as iron chlorosis. If a soybean variety is suspected of being sensitive to metribuzin, check with the soybean seed company before treating a field of that soybean variety with TRIVENCE.
Excessive rainfall received after application but before soybeans germinate may cause soybean stunting. Injury is more prevalent under poor drainage or compacted conditions or when soil is saturated for long periods of time. Excessive rainfall received in a short period of time following the emergence of soybeans treated with a preplant or preemergence application of TRIVENCE herbicide may cause minor leaf burn, crinkling, or defoliation of some lower leaves of the soybean plants. Excessive periods of rainfall and cool, cloudy weather may cause temporary soybean stunting. Seedling disease, nematodes, cold weather, deep planting (more than 2”), excessive moisture, high salt concentration, or drought may weaken soybean seedlings and increase possibility of crop injury. Mechanical incorporation into the soil will reduce residual weed control. Calibrate sprayers only with clean water away from the well site. Make scheduled checks of spray equipment. Ensure that all operation employees accurately measure pesticides. Mix only enough product for the job at hand and avoid overfilling of spray tank. When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix. Thoroughly clean DuPont TRIVENCE from application equipment immediately after use and prior to spraying crops other than soybeans. Failure to remove even small amounts of TRIVENCE from application equipment may result in injury to subsequently sprayed crops. Tank mixtures of TRIVENCE plus organophosphate insecticides applied preplant or preemergence to DuPont STS, STS/RR soybean varieties or soybeans with BOLT technology, may result in minor transient crop response (i.e. stunting and/or chlorosis). Prevent drift of spray to desirable plants. Keep from contact with fertilizers, insecticides, fungicides and seeds during storage. Avoid storage of pesticides near well sites. Injury to soybeans may occur if TRIVENCE is used on soils having a calcareous surface layer or pH greater than 7.5.
