Pheromone traps in southern and southwestern Illinois have begun capturing codling moths in significant numbers. Remember that cover sprays for codling moth control should be applied by 240 DD after traps first catch an average of 3 moths. Be sure to scout for this insect at petal fall. If WALH control is warranted, adding Provado to the petal fall spray is effective and will give some control of spotted tentiform leafminer. Provado is low in toxicity to predaceous mites.

It also gives some control of spotted tentiform leafminer. Pheromone traps in southern and southwestern Illinois have been catching lesser peachtree borer moths for at least a week.
