Abstract:

Chrysanthemum cultivars grown for pot flower production in greenhouses exhibited various and potentially useful levels of resistance to Liriomyza trifolii (Burgess). Leafminer control with insecticides was significantly (P <0.05) enhanced when applied to resistant varieties. Evaluations of insecticides showed an initial tolerance of the South Carolina population to permethrin and moderate control (71%) by foliar treatment with encapsulated methyl parathion. Permethrin regained efficacy after a 6-month period during which pyrethroid sprays were withheld. Methamidophos, cypermethrin, and permethrin treatments resulted in 90 +% control in subsequent tests, but methamidophos was phytotoxic to foliage of most cultivars at standard application rates. Tank mixes of pyrethroids and encapsulated methyl parathion gave greater efficacy than either chemical used alone. Fenvalerate treatments provided moderate control. Oxydemeton methyl showed no efficacy against the leafminer.
