Abstract
The pyrrole Alert® (AC303,630) has been evaluated against citrus mite Phyllocoptruta oleivora (Ashmead), in Florida citrus on 9 occasions since 1989. Formulations, rates/acre, tank mix compatibility and spray volume/acre were investigated in an attempt to elucidate its capabilities as a potential miticide for citrus rust mite management. A 2 lb.AI/ gallon suspension concentrate (2SC) formulation was eventually selected for evaluation. It was compatible in tank mixes with chlorpyrifos, a shotgun nutritional mix, tribasic copper, and in oil emulsion sprays. Other mixtures were not tested. It was effective in spray volumes of 100 to 500 gallons and successful rates in those volumes ranged from 0.1 to 0.3 lb. AI pyrrole. Results with lower rates were inconsistent.
