Interpretive Summary: Vegetable crops in the southeastern U.S. are commonly grown on plastic mulch with two crop cycles produced on a single mulch application. Field trials were conducted in 2013 and 2014 in two locations to evaluate the efficacy of a new nematicide called fluensulfone when applied through a drip system to the second crop in a double-crop cycle. In the spring tomato crop, the fumigant 1,3-dichloropropene (1,3-D), fluensulfone, and a resistant cultivar significantly decreased root galling from root-knot nematodes by 91%, 73%, and 97%, respectively, compared to the untreated control. Tomato plots from the spring were divided into split-plots for the fall where the main plots were the spring treatment and the subplots were cucumber either treated with fluensulfone applied through drip irrigation or left untreated. The fall application of fluensulfone improved cucumber vigor and reduced gall ratings compared to untreated subplots. Fluensulfone reduced damage from root-knot nematodes when applied to the first crop as well as provided additional protection to the second crop when it was applied through a drip system

Technical Abstract: Vegetable crops in the southeastern U.S. are commonly grown on plastic mulch with two crop cycles produced on a single mulch application. Field trials were conducted in 2013 and 2014 in two locations to evaluate the efficacy of fluensulfone when applied through a drip system to the second crop in a double-crop cycle. In the spring tomato crop, 1,3-dichloropropene (1,3-D), fluensulfone, and a resistant cultivar significantly decreased root galling by 91%, 73%, and 97%, respectively, compared to the untreated control. Tomato plots from the spring were divided into split-plots for the fall where the main plots were the spring treatment and the subplots were cucumber either treated with fluensulfone (3.0 kg a.i. ha-1. via drip irrigation) or left untreated. The fall application of fluensulfone improved (P = 0.006) cucumber vigor and reduced gall ratings (P = 0.002) compared to untreated subplots. Fluensulfone reduced damage from root-knot nematodes when applied to the first crop as well as provided additional protection to the second crop when it was applied through a drip system.
