Field Crop Pests: Farmers Report the Severity and Intensity

摘要

The extent of pesticide use and the prevalence of pest populations on field crops vary according to the type of pest, crop, region, and survey year. This report estimates the importance of individual pests on selected field crops on a regional and national basis. Surveyed farmers report that the most severe and intense pests were weeds in corn and soybean production, weeds and insects in cotton, and diseases and insects in tobacco. This study relied upon farmers' ability to identify the pest infestations causing economic damage on nine selected field crops. Detailed estimates of the relative importance, severity, and time intensity of target pests are tabulated.
