Abstract
In field trials conducted on carrots, cucumber and cantaloupe, Nimitz (MCW-2, fluensulfone 480EC) 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 all trials were Nimitz at 2, 3, 4, and 8 kg ai/ha, oxamyl at 4.7 L/ha, metam sodium at 589 L/ha, 1,3-dichloropropene (Telone II, 1,3-D) at 84 L/ha and an untreated control (UC). 1,3-D was injected 14 days preplant.
Metam sodium, Nimitz and oxamyl were applied 7-days preplant followed by tilling to 10 cm, and sprinkler irrigation.
Evaluations were conducted at harvest.
The 3 and 8 kg rates of Nimitz had a higher percent of marketable carrots.
All Nimitz rates and 1,3-D had fewer RKN. On cucumbers, 4 and 8 kg Nimitz had a greater number and weight of fruit.
Nimitz at 8 kg had a lower root gall rating (RG). All treatments except 2 kg Nimitz had fewer RKN. On cantaloupe, 2 and 4 kg Nimitz, 1,3-D, and metam sodium had a greater fruit weight.
Nimitz at 4 kg and metam sodium had a larger number of fruit.
Nimitz at 3 kg had larger fruit.
At 2 and 8 kg, Nimitz had a lower RG. All treatments had fewer RKN than UC. Based on the results of these trials, Nimitz shows promise for use in IPM programs for managing RKN on annual crops.
