Abstract

Effectiveness of vermicompost with additives of various botanical pesticides in controlling Plutella xylostella and their effects on the yield of cabbage (Brassica oleracea L.var. Capitata)

Highlights

  • The horticultural plant cabbage (Brassica oleracea L.) has been an economic role in Asia and Africa (Grzywacz et al, 2010)

  • The organic fertilizers can increase the populations of beneficial microorganisms in the soil that act as the natural enemies of P. xylostella

  • Effect of vermicompost in combination with various botanical pesticides on attack intensity of Plutella xylostella Vermicompost in combination with various botanical pesticide additives significantly affected the intensity of pest attacks on cabbage in all observations

Summary

Introduction

The horticultural plant cabbage (Brassica oleracea L.) has been an economic role in Asia and Africa (Grzywacz et al, 2010). The population of P. xylostella is influenced by abiotic and biotic factors such as rainfall, temperature, host plant, natural enemies and cultural methods, especially in vegetable crops. Their presence can cause high production losses leads to a decrease in income earned by farmers, threatening the sustainability of small farmers whose income is entirely dependent on their production (Sow et al, 2013). Chemical pesticides used to control P. xylostella populations can introduce undesired side effects on the environment, such as environmental pollution and the reduction of natural enemies of P. xylostella. This study aimed to illustrate the effect of vermicompost with additives of various botanical pesticides on the attack intensity of diamondback moth and the cabbage yield
