Field efficacy of bio foliar formulations for control of mulberry sucking pests

Abstract

Utilization of organic formulations in pest management is a cheap, environmentally friendly alternative to chemical pesticides. This study was designed to investigate the effects of organic formulations on sucking pests damage to mulberry leaves. A field experiment was conducted with irrigated V1 mulberry variety, Department of Sericulture, Forest College and Research Institute, Mettupalayam during 2017-2018 which was laid out in Randomized Block Design with five treatments and four replications. The applications of bio foliar formulations were given thrice at 15, 30 and 45 days after pruning using knapsack sprayer and data on pest population was counted weekly for two seasons. Analysis of variance revealed significant differences between the treatment groups at 5% probability level. The results revealed that the minimum damage by different pests viz., Pseudodendrothrips mori and Aleurodicus dispersus were observed in EM and panchagavya applied plants. Thus, the foliar spray of panchagavya at 3 per cent on 15, 30 and 45 DAP is ideal for magnify the mulberry sucking pests.
