Frequently Asked Questions

Q. How effective is Mustang® insecticide?
A. Research conducted at leading universities and by FMC demonstrates that Mustang has excellent efficacy and residual against adult rice water weevils, chinch bugs and other labeled pests. In fact, Mustang controls a broader range of insects than conventional and biological rice insecticides. And it makes a terrific partner for other insecticides in your integrated pest control program.
 
Q. How will Mustang affect my yields?
A. When you control damaging insect pests, one of the primary stresses to your crop is eliminated. Insect control, weed control and a good fertility program ensure that you've provided the best scenario for high-quality rice. And you don't have to worry about Mustang injuring sensitive young rice seedlings.
 
Q. What is Hydro-Formulated Technology™ ?
A. Hydro-Formulated Technology, or HFT™, formulations are made by an innovative process which delivers the active ingredient in submicron size. This improves performance and product stability, so the effectiveness of Mustang is less susceptible to variables in water hardness, temperature, pH or tank residues. The process improves tank-mix compatibility and eliminates the need for petroleum distillates, making Mustang less likely to cause skin irritation.
 
Q. What is the active ingredient?
A. Mustang contains zeta-cypermethrin, a highly recognized insecticide widely used throughout the United States. Mustang is labeled for use on alfalfa, corn, soybeans, wheat, sorghum, sugar beets and more than 60 vegetable crops.
 
Q. How environmentally friendly is Mustang?
A. Rates of application are very low, so less chemical is introduced into the environment. What's more, when used according to directions, the active ingredient in Mustang has low potential risk to birds, earthworms, mammals or people. As with any insecticide, label directions, application precautions and requirements for worker and handler protection must be followed carefully.
 
Q. How should I scout for rice water weevil adults
A. Dry seeded rice - Begin scouting fields after the permanent flood has been established. Examine plants throughout the field and continue scouting every three or four days. Treat when at least 60 percent of the youngest mature leaves on the plant have adult feeding scars. For dry-seeded rice, an application is usually timed within ten days after permanent flood establishment. Water seeded - Begin scouting when seedlings emerge from the flood. An application is recommended when 50 percent of the plants have adult feeding scars. In water-seeded rice, an application usually begins when rice has emerged ½ inch above the waterline.
 
Q. What is the life cycle of the rice water weevil?
A. Rice water weevils overwinter as adults in bunch grasses and in leaf litter. The adults fly into flooded fields where they feed and the females lay eggs in the leaf sheath that hatch in four to nine days. The larvae initially feed on the leaf sheath before burrowing into the soil where they feed on the roots. Pupation occurs in a watertight cocoon and lasts five to seven days. There may be more than one generation per season depending on the location. The adults fly to overwintering sites.
 
Q. How long will Mustang continue to control insects after an application?
A. Mustang has a longer residual than many other foliar products. This may allow you to reduce applications of insecticide while maintaining insect control.
 
Q. Are there rotation restrictions?
A. Rotational crops may be planted 30 days after the last application of Mustang.
 
Q. How long should I wait before harvesting?
A. Applications can be made up to 14 days of harvest.
 
Q. Will Mustang cause skin irritation?
A. Unlike other insecticides, Mustang doesn't use petroleum distillates to deliver its active ingredient. That means Mustang won't burn or speckle sensitive crops, and it's less likely than other products on the market to irritate your skin.
 
Q. Is Mustang expensive?
A. No. In fact, Mustang typically costs less per acre than other competitive products. Plus, you get better insect control. That makes Mustang a truly exceptional value.
