Abstract
In two field trials conducted on tomatoes, Nimitz (MCW-2, fluensulfone) was evaluated (P≤0.05) for management of root-knot nematode (RKN) (Meloidogyne javanica). Each trial was a randomized complete block with 5 replicates per treatment.
Treatments in the first trial were Nimitz at 2, 3, 4, 6, and 8 kg ai/ha, oxamyl (Vydate), metam sodium (MS), 1,3-dichloropropene (1,3-D, Telone II) and untreated control.
At harvest, 4 kg Nimitz had a greater weight of fruit plus foliage.
MS had a greater weight of fruit plus foliage and a greater weight of fruit. 3, 4, and 8 kg Nimitz and 1,3-D had a lower root gall rating (RG). 4 and 8 kg Nimitz and 1,3-D had fewer RKN. Treatments in the second trial included combinations of Nimitz, methyl bromide/chloropicrin (MBrCP), 1,3-D, chloropicrin (CP), metam postassium (KPam), oxamyl, azoxystrobin (Quadris), metalaxyl (Ridomil), halosulfuron-methyl (Sandea), metribuzin (Canopy), metolachlor (Parallel), an untreated control, and a hand weeded control.
The herbicides tested exhibited a range of weed control from low (1,3-D, 65% overall control at 2 or 4 kg) with some differences on particular weed species.
Nimitz at 2 and 4 kg when used in combination with CP and KPam had greater yields than untreated control.
MBrCP and all treatments containing Nimitz had lower RG at harvest than untreated control.
Based on the results of these trials, Nimitz shows promise for use in IPM programs for managing root-knot nematode on tomatoes.
