CABBAGE NEMATICIDE TRIALS

H. L. Rhoades

Cabbage is an important vegetable crop in Florida with a reported value of
$40.74 million in 1983-84 on 11,000 harvested acres. It is produced primarily on
fine sand type soils where it is attacked by several plant nematode species.
Particularly important are the sting nematode,:Belonolaimus longicaudatus; the
root-knot nematodes, Meloidogyne spp.; and in Seminole County, the cyst nematode,
Heterodera schachtii.

Two nematicide trials (one in the fall and winter of 1984-85 and the other
in the winter and spring of 1985) were conducted at the Central Florida Research
and Education Center, Sanford, on Myakka fine sand infested with B. longicaudatus
and H. galeatus. The experiments were designed to compare the efficacy of soil
* fumigants and nonfumigant organophosphorus and carbamate nematicides. The experi-
mental design was a randomized complete block with five replicates for both
experiments. Plot size was 5 feet (2 rows) X 38 feet. The nematicides involved
in the tests were:

1. Telone II (1,3-D), Dow Chemical Co.
2. Busan (SMDC), Buckman Laboratories, Inc.
3. Mocap (ethoprop), Rhone-Poulenc, Inc.
4. Nemacur (fenamiphos), MOBAY Chemical Corp.
5. Furadan (carbofuran), FMC Corp.
6. Counter (terbufos), American Cyanamid Co.
7. Vydate (oxamyl), E. I. DuPont de Nemours & Co., Inc.
8. Standak (aldoxycarb), Union Carbide Agricultural Products Co.

In the fall experiment the soil fumigants were applied on October 10, 1984. "
Telone II was applied.6 inches deep at 10-inch intervals (single line of.injections)
in the center of the row with a hand injector. Busan was applied with two chisels
spaced 10 inches apart and 6 inches deep for each row. The nonfumigants were
applied on October 22. Granular formulations of Mocap, Nemacur, Furadan, and Counter
were applied as 15-inch bands in-the-row and incorporated 2-3 inches with spiked
rotary cultivator wheels. Liquid formulations of Vydate and Standak were applied
in water as a spray in a 15-inch band, then incorporated in the same manner as the
granules. In addition, liquid Mocap was applied at two rates as broadcast treat-
ments incorporated 2-3 inches deep. 'Rio Verde' cabbage was transplanted on
October 23. Normal cultural practices were followed and the cabbage was harvested
three times during January 9 February 13, 1985. Soil samples were collected for
nematode population determinations on January 7, 1985.

The results are presented in Table 1. All treatments reduced B. lonngicaudatus
populations, and the soil fumigants were effective in reducing H. galeatus popu-
lations, whereas the nonfumigants were not. However, even though the yield from
check plots was considerably less than for all treatments, this difference was not
significant because of the high variability among replicates.

In the spring experiment, the soil fumigants, Telone II and Busan, were both
injected as in-row treatments with a hand injector on March 1, 1985. Telone II was
applied as a single row of injections spaced 10 inches apart and 8 inches deep, and
Busan was applied in 2 rows spaced 10 inches apart. The nonfumigants were applied
on March 5 in the same manner as in the fall experiment and 'Rio Verde' cabbage was
transplanted on March 6. Normal cultural practices were followed and the cabbage
was harvested twice (May 16 and 28). Soil samples were collected for nematode
population determination on April 22.

The results are presented in Table 2. All materials greatly reduced
B. longicaudatus populations with the fumigants reducing them to the lowest level
The fumigants were also effective in reducing H. galeatus populations, but the
nonfumiants were not. All treatments, but Furadan at 2 Ib/A and Mocap at both 2
and 3 Ib/A, increased yield significantly.
