Abstract

This study aimed to evaluate the efficacies of pesticides Cypercal 50 EC®, K-OPTIMAL 35 EC® and K-TOTAL 35 EC® on the number and damage of D. hyalinata on cucumber in Man locality. Cucumber seeds were sown on January 25, 2021 (dry season) and May 16, 2021 (rainy season) in half-hectare divided into 4 equal parts. Cucumber plants damaged and the fruits attacked were higher during the dry season. The plant damage in the treated plots ranged from 16 to 26% and the fruit damage ranged between 12 to 21%. The lowest number of D. hyalinata larvae was recorded in the plots treated with Cypercal 50 EC®.
