You can check with Sevin to see if your fruit is on their list....wait for the sun to pass and the tree is cooled off.................keep children & pets away until it is dry...........to prevent this for next year.........in the fall spray it with dormant oil................that smothers any eggs.........and again in the spring........read the label carefully. Wear old long clothes, goggles, mask, hat & gloves. Don't spray if it is going to rain....or if it is windy. Good luck with your tree.
