| abamectin + cyantraniliprole (Minecto Pro) 33023 | 6 + 28 | 496 mL | 201 mL | 12 h | 28 | Apply against egg (to control new hatch) and early sap feeder stages of first and second generation tentiform leafminers when locally established thresholds have been reached.

| Notes: The leafminer parasite is an effective biological control agent. 30% parasitism of first generation tissue-feeder larvae in the spring will provide control of leafminers for the rest of the season. If chemical control is needed rotate products for resistance management. Avoid using Group 4 products more than twice/season for all registered uses to prevent mite problems. | ||||||
