What is the rate of Permethrin SFR 36.8% to kill sod webworms? I am using a 2 gallon sprayer and my grass is about 3.5-4 inches tall. Do I need to saturate the lawn or water in?

Answer:

Permethrin SFR 36.8% is applied at 0.4 to 0.8 fl oz in 4 to 25 gallons of water per 1000 sq ft for sod webworms. Ensuring you use enough water volume to get the applicaiton into the soil is crucial in getting results as these turf insects are under the soil surface. Use the higher rate for fast knockdown and increased residual control. Dense or excessive (greater than 3 inches) lawn height and arid conditions may require higher volume application rates. Repeat application if necessary. Application in combination with compatible surfactants or wetting agents may enhance penetration. Please view the product label for more information.
