I need help, folks.

I looked up the label for Permethrin SFR, which is 36.8% active ingredient.

The label states 1/4 to 3/4 tsp. of permethrin per gallon of water for peaches. One gallon of spray solution is supposed to treat 436 sq. ft. of peaches, which is a peach tree with roughly a 20ft. spread (a large peach tree). If you have heavy pressure, use the higher rate (3/4 teaspoon/gal).

Curculio starts to hit peaches here when they are out of the shuck. So I would advise you to make your first spray soon after shucks are off.

Thank you, olpea! I must have a different brand of Permerthrin SFR that you have, since the label on mine has nothing about mixing one gallon. I just sprayed all my plum trees since they have fruit over 1/8" in diameter today. Peaches have not appeared yet.

Thanks again!
