Fruit tree spraying

Asked July 1, 2016, 3:57 PM EDT

I have been spraying my apple trees with Malathion at a mix ratio of 2 Tbs/Gl.
What is the correct interval to spray the trees?

Malathion works very well, but it does not last very long on the fruit. So technically, the interval is around 7 to 10 days, repeating throughout the summer so that your last application is 7 to 10 days before Sept. 15. (If you have not already harvested.)

If you have any other questions, you can contact James Barnhill, who is the agriculture agent in your county.
