Abstract
An experiment was conducted to test the efficacy of Landa-Cyhalothrin Pesticides against Onion Thrips, Thrips Tabaci L. (Thysanoptera: Thridae) on Onion at Gudera area Toke Kutaye district and Holeta area in Walmera district during 2019 cropping season, using randomized complete block design with four replication at both locations. The result of Bartlett’s test confirmed the homogeneity of variance for all collected which allowed applying combined data analysis and the analysis of variance (ANOVA) of combined data of the two locations revealed highly significant difference among the treatments after spraying of day 1, day 3, day 5, day 7, total mortality percentage, yield, and yield loss. In the present study, the maximum mortality rate percentage of onion thrips was manifested for Lamda-Cyhalothrin than Diazinon60% EC, and zero yield loss was recorded for Lamda-Cyhalothrin treated plot, while 25.95 yield loss was manifested for Diazinon60% EC. Therefore, Lamda-Cyhalothrin 100g/lt is efficient for onion producers to control onion thrips and it can be replaced or comparable to other insecticides
