Interpretive Summary:

Technical Abstract: The influence of bahiagrass, corn, and cotton in rotation with peanut and chemical treatments with and without aldicarb, or flutolanil, or aldicarb + flutolanil was studied for 3 years. Peanut yields following either 1 or 2 years of bahiagrass, corn, or cotton were higher than those of continuous peanut. Peanut yield means across cropping sequences were highest in the aldicarb + flutolanil-treated plots (5,270 kg/ha), intermediate in aldicar (4,060 kg/ha) and flutolanil-treated plots (4,590 kg/ha), and lowest in untreated-plots (3,690 kg/ha). The increases in peanut yields obtained in response to cropping sequences and chemical treatments resulted from suppression of Meloidogyne arenaria, thrips, Sclerotium rolfsii, and Rhizoctonia solani population densities. Our data demonstrate the sustainable benefits and yield increase from using corn, cotton, or bahiagrass in integrated systems with chemical treatments for multiple-pest tmanagement in peanut production.
