Abstract

Sesame webworm (Antigastra catalaunalis) is the major pest, which is causing heavy losses in Humera areas, northern Ethiopia. The present study aims to determine schedule of insecticide application for control of the pest. An experiment with a randomized complete block design (RCBD) was conducted at Humera Agricultural Research Center to evaluate nine insecticide application schedules. Result of the experiment indicated that weekly spray (S9) resulted in lower webworm incidence (19.5%) and better grain yield (536.6 kg/ha); and highest incidence (99.27%) and lowest grain yield (154.9 kg/ha) was recorded from control. Maximum level of leaf and flower was scored on control and once sprayed plots, while the lowest was on the frequently sprayed. In conclusion, twice application of insecticide at 2 and 4 weeks after emergence was found better for controlling A. catalaunalis.
