Fall and spring fumigation rates of Telone II were compared to Temik 15G at planting for their effectiveness against reniform nematodes (Rotylenchulus reniformis) over a two-year period. The two nematicides increased yield over the untreated check both years. Yields in Telone treated plots were significantly higher than Temik treated plots. Temik’s failure to properly activate under extremely dry conditions at planting in 1999 and 2000 growing seasons could account for the nematicide’s poor performance.
