I have about 100 Scots Pines that are infested with Zimmerman Tree Moths. How much would you recommend I buy? How many tablespoons per gallon should I use?
Hi-Yield 38-Plus Insect Control - 38% Permethrin would be mixed at 0.04 to 0.08 fl. oz per gallon of water per the product label. Each gallon will cover approx 1000 sqft. Timing is key, per the label to control Webbing Coneworm make first application just prior to peak pollen flight. To control other Coneworms and Seed Bugs, make application 30 days prior to flower closure.
