2024 Guidelines for Whitefly / CYSDV Management on Fall Melons

Abstract

This IPM short provides comprehensive guidelines for managing sweetpotato whitefly (Bemisia tabaci) and Cucurbit yellow stunting disorder virus (CYSDV) in fall melon production systems of the desert Southwest. Based on nearly two decades of monitoring and field research, the publication outlines trends in whitefly populations and virus incidence across Arizona growing regions and presents a three-stage insecticide program integrated with cultural practices such as crop isolation, sanitation, and use of row covers. Special attention is given to minimizing pollinator risk during bloom, making this a vital tool for sustainable melon production.
