Cultural Practices Key to Whitefly and Virus Management in Fall Melons

Abstract

This IPM short highlights the importance of cultural practices in managing whiteflies (Bemisia tabaci) and Cucurbit Yellows Stunting Disorder Virus (CYSDV) in fall melons in the desert Southwest. While insecticide-based programs are effective, reliance on chemical control increases costs, disrupts beneficials, and drives resistance. This publication outlines key preventative practices such as crop isolation, sanitation, optimized crop management, and use of row covers to reduce virus risk. Emphasis is placed on managing whitefly migration and suppressing virus reservoirs, providing a holistic strategy for virus mitigation and sustainable melon production.
