Chapter 16 - The Use of Vermiwash and Vermicompost Extract in Plant Disease and Pest Control

Abstract

Organic approaches of pest and plant disease control using pesticides need to be seriously evaluated to counter the negative impact of high agrochemical input in conventional agriculture. This approach is possible through utilization of vermiwash and vermicompost extract, products derived from vermiculture and vermicomposting process, respectively. The products contain high variation of compounds rich in beneficial microorganisms, nutrients, vitamins, and growth hormones that serve as biofertilizer and biocontrol agents against diseases and pests. Liquid forms of vermicompost derivatives are more efficient compared to solid forms due to its ability to reach the target area on plant above ground through foliar application and rhizosphere part of plant underground through soil drench. Vermicompost derivatives can be solely used or mixed with solid vermicompost, fertilizer, or any organic material in soil to achieve the best result not only for pest and disease control but more importantly for soil health and plant growth.
