PRODUCT INFORMATION
Cobra Herbicide is a selective, broad spectrum herbicide for preemergence and postemergence control of susceptible broadleaf weeds. Cobra Herbicide is formulated as an emulsifiable concentrate containing 2 lbs of active ingredient per gallon. In the Midwest, postemergence application of Cobra Herbicide to soybeans (at or just before 1st bloom) has resulted in suppression of the soybean disease white mold caused by Sclerotinia sclerotiorum.
Cobra Herbicide works primarily through contact action. Good coverage of young, actively growing weeds is essential for maximum weed control. The use of a spray adjuvant is usually required. Refer to the label section on ADJUVANTS AND ADDITIVES for specific recommendations.
When Cobra Herbicide is applied postemergence, a portion of the spray solution may contact the soil surface. If soil moisture conditions are favorable for preemergence activity following the application, suppressed germination of small-seeded broadleaf weeds, such as nightshade and pigweed species (including waterhemp and Palmer amaranth) may be expected for a 2 week period with rates of 10 fl oz/A or greater. The presence of excessive crop or weed foliage at the time of application will reduce the amount of herbicide spray contacting the soil surface and will reduce the level of soil activity.
A temporary crop response should be expected following a postemergence application of Cobra Herbicide. Leaves which are open at the time of application will show some burn, bronzing and speckling. Leaves which have emerged but are unopened at the time of application may appear cupped at the tip and/or crinkled along the edges of the leaf.
Labeled crops quickly outgrow all initial herbicide effects. When Cobra Herbicide is used as directed yields will not be adversely affected.

RESTRICTIONS
Do not apply this product through any type of irrigation system.
Do not make more than two applications per acre per season.

ENVIRONMENTAL CONDITIONS AND BIOLOGICAL PERFORMANCE
For best results, apply Cobra Herbicide to actively growing weeds within the growth stages indicated in this label. Applying Cobra Herbicide under conditions that do not promote active weed growth will reduce herbicide effectiveness. Do not apply Cobra Herbicide when the crop or weeds are under stress due to drought, excessive water, extremes in temperature, disease or low humidity. Weeds under stress tend to become less susceptible to herbicidal action. Cobra Herbicide is most effective when applied under sunny conditions at temperatures above 70o F.
