Insecticidal management of lucerne leafroller merophyas divulsana walker lepidoptera tortricidae on lucerne in queensland


Insecticidal management of lucerne leafroller merophyas divulsana walker lepidoptera tortricidae on lucerne in queensland



Plant Protection Quarterly 7(1): 17-18



Three trials were conducted to find chemical alternatives to carbaryl and methidathion, for the management of lucerne leafroller Merophyas divulsana (Walker), on lucerne in Queensland (Australia). Chlorpyrifos at 300 ga.i. ha-1 gave better control than the recommended treatments of carbaryl at 840 a.i. ha-1 or methidathion at 350 g a.i. ha-1. At the low rate of 100 g a.i. ha-1, chlorpyrifos provided satisfactory control. Its use is discussed in relation to effects on key aphid pests and their natural enemies.
