Abstract
Reniform nematode (Rotylenchulus reniformis) currently infests 36% of Mississippi cotton acreage causing economic losses of $130 million annually. With Temik 15G being removed from the market, there is a need to better understand nematode management programs centered on Nematicide Seed Treatments (NST). Economic threshholds for R. reniformis in Mississippi on medium-textured soils range from 1,000 to 5,000 R. reniformis/500 cm3 of soil depending on season. This study aimed to determine effects of R. reniformis and efficacy of NST compared to Temik 15G on cotton growth. In greenhouse studies, all plants treated with NST had greater root and shoot biomasses compared to the untreated control within nematode populations. For treatments inoculated with a range of R. reniformis/500 cm3 soil (Pi), greatest shoot biomass occurred in plants treated with Temik 15G at 2,500 Pi, and greatest root mass occurred in plants treated with Temik 15G whether Pi was 2,500, 5,000, or 7,500. Plants treated with Aeris® alone provided suitable root and shoot growth at 2,500 Pi, but became less effective at 5,000 Pi. Plants treated with Aeris® + Votivo® at 2,500 Pi produced greater root and shoot biomass compared to plants grown in soils with 5,000 or 7,500 Pi.
