Rhone-Poulenc Nematicide in Peanut 1995

The trial reported herein was conducted to determine nematicides and rates for

management of Meloidogyne arenaria on peanut.

Materials and Methods

A field trial was conducted in a sandy loam soil infested with the peanut root-

knot nematode, Meloidogyne arenaria. The test site was on the John King farm near

Greenwood, Florida and was prepared by moldboard plowing and discing prior to

treatment applications. Vapam and Telone II were applied with a single chiesel 12"

deep on May 16, 1995. Temik 15 G application was made in the furrow at planting

with a Gandy granular applicator on May 25, 1995. Peanut cv. Southern Runner was

planted in 2-row (36" wide rows) x 20' long plots. Treatments were replicated 5 times

and placed in a randomized complete block design. One treatment received an at-

pegging application of Temik 15 G in a 14" wide band 34 days after planting.

Plants were monitored for phytotoxicity early in the season and harvested on

November 19, 147 days after planting. Peanuts from individual plots were forced

air-dried to 10% moisture and weighed. Pods were rated on a 1-5 scale with 5

representing the combination of worst pod discoloration and highest galling levels. Five

soil cores (1" dia.) were taken on October 25 from each plot and individual plot samples

composite. Second-stage juveniles of M. arenaria were extracted from the 100 cm3

subsamples by a modified centrifugation-flotation technique and counted.

Results and Discussion

Yield of peanut was not significantly increased with any treatment. As

anticipated, however, the Telone II + Temik 15 G and the Temik 15 G + Temik 15 G









(10 lbs. + 10 lbs.) were the highest yielding treatments. Nematode numbers were only

significantly reduced by the Telone II + Temik 15 G treatment over those of the

Thimet 15 G control. Highest nematode number and lowest yield were found in the

Vapam treatment. A combination of factors resulted in few significant differences in

yield. The most important appeared to be uniformly high initial nematode populations,

the very sandy soil, and scattered out breaks of tomato spotted wilt virus. Little

information was established from results of this study. These data, however, may

indicate that root-knot nematodes in such high initial populations overwhelmed these

three nematicides. This further supports conclusions that combinations of rotation and

nematicides for control of the peanut root-knot nematodes is needed.

worst quality.
