Anyone have a ratio of permethrin per gallon of water to knock down army worms? They ate 2 duck holes planted in millet that were 12" tall to the dirt in about 5 days. Still have 3 more they havent got to yet so need to treat them.

Herbicides and pesticides are applied by area. A hand sprayer vs a boom are going to put dramatically different amounts of spray on an area, what matters is how much chemical goes on the plants.

Per chatGPT the label rate for a 36.8% concentrate is 17-34 ounces per acre. So estimate the total area you’re trying to spray, put that many ounces in the sprayer, then fill with water to the top so you can get good coverage.

Is Permethrin labeled for use on millet? I’ve always used lambda cy.

Permethrin is a first gen insecticide. Been used for years and bugs get immunity. Use bifenthrin 7.9. Mix 3 oz per gallon water.
