Brood X of the 17-year cicada are set to emerge this year and if they didn’t go extinct like the last brood did, young fruit trees are in for a world of hurt. Pesticides are not effective Cicada control and I do not personally want to end them like I do other pests. But the females will be damaging any limb about pencil thick.
Theory 1, cicada damage to an established tree will promote flowering and fruit production next year.
Theory 2, cicada damage to an established tree will promote blacknot, firelight and other fungal infections
Theory 3, young trees 1-2 years in the ground need protection.
I plan to be extra diligent with Kocide treatments this year. Any ideas for possible cicada repellents please post your theories and results.
