Outlined below are the IR-4 Projects underway at the Agricultural Research &
Education Center-Bradenton, dealing with ornamental plants and vegetable crops.

TITLE: Etiology, symptomatology and control of diseases and floral crops

AUTHOR: A. W. Engelhard
ABSTRACT: The 1980 IR-4 fungicide program includes 10 crops (azalea, caladium,
carnation, chrysanthemum, geranium, hydrangea, nasturtium, periwinkle,
poinsettia and statice), and 4 fungicides (iprodione Rovral; chlorothalonil =
Daconil 2787; mancozeb Manzate 200 or Dithane M-45; and the mixture of thio-
phanate methyl + terrazole = Banrot). The chemicals are evaluated for phyto-
toxicity and/or efficacy as drenches or foliar sprays in the greenhouse and/or
field, depending upon what the IR-4 priority needs require.

TITLE: Insecticides on various flowers
AUTHOR: J. F. Price
ABSTRACT: Twenty greenhouse and field experiments involving IR-4 insecticide and
miticide projects have been completed on flowers in 1980. Chemicals tested
were those that appeared to have the most beneficial impact on crops in
Florida and included Bacillus thuringiensis, bendiocarb, pirimicarb, oxamyl,
methomyl, and dienochlor applied as fliar sprays and permethrin and
resmethrin applied as pot drenches. Plant subjects were azalea, snapdragon,
zinnia, salvia, rose, gypsophila and statice.
All specifications of the IR-4 protocols were followed. Materials were
applied at least four times at 1 week intervals. Evaluations of phytotoxicity
to flowers and foliage were made ca. 2 days after each application. Data of
arthropod responses to the chemicals were collected where arthropods were
abundant.
Most of the projects developed data to support the register of the
chemicals for the tested purposes. Pirimicarb occasionally results in
excessive leaf burn.











IR-4 PROJECT NO: 643

TITLE: Clearance of aldicarb for use on eggplant

AUTHOR: A. J. Overman

ABSTRACT: The protocol was initiated in North Carolina for insect and nematode
control using Union Carbide EPA Reg. No. 1016-78 Temik 15G at a 3 lb ai/a
rate. Previous work indicated this rate was too low for nematode control
in Florida's sandy soils so a request was granted to include 10 Ib ai/a
in the project.
Efficacy data and fruit samples for residue analysis were collected
from a test on Myakka fine sand under a full-bed mulch crop management
system. Treatments of 3 and 10 lb ai/a Temik 15G (on gypsum base) were
broadcast, rototilled 2 inches deep, bedded, fertilizer was applied, and
the beds were mulched with 1.0 mil white/black polyethylene film. All
plots were 30 ft. long (harvest from middle 10 feet) and replicated 4
times. On the day of treatment, May 30, containerized transplants of
eggplant 'Jersey King Hybrid' were set 1 foot apart in the row.
At first harvest, 3.0 Ibs fruit per replicate of each treatment were
collected by selecting a one quarter section of each fruit between 6 and 8
inches long. The residue samples were frozen and submitted to the
Gainesville laboratory for analysis.
Harvests were recorded weekly from July 31 through September 12.
Soil samples were collected September 12 for nematode assay by the
Modified Baermann technique.




IR-4 PROJECT NO: 1235

TITLE: Clearance of oxamyl for nematodes for use on okra

AUTHOR: A. J. Overman

ABSTRACT: DuPont Vydate L EPA No. 352 372 AA was incorporated into beds of
Myakka fine sand at 4 and 8 lb ai/a. All treatments were replicated 4
times. Appropriate controls were included. Plots were 30 feet long beds
under a full-bed plastic mulch crop management system.
Treatments were applied and okra 'Clemson Spineless' seeded on
May 30.
Residue samples were collected at harvest (3 Ibs of fruit/plot),
frozen, and submitted to the Gainesville Pesticide Laboratory for
analysis.
Yields were recorded from August 2 through September 12.
Soil samples were collected from each plot on September 12 for
nematode assay.

IR-4 PROJECT NOS: 562, 745

TITLE: Insecticides on strawberries

AUTHOR: J. F. Price

ABSTRACT: Oxamyl and chlorpyrifos were sprayed on strawberry plants prior to
bloom to assess toxicant accumulation in strawberry fruit. This project
was in support of an IR-4 effort to register Vydate and Dursban for
lygus bug control.
Fruit production was recorded for the entire season and fruit
samples were supplied to the IR-4 laboratories for analysis of chemical
residues. There were no phytotoxic effects from oxamyl and chlorpyrifos
at any of the 3 rates of application tested.




IR-4 PROJECT NOS: 620, 690, 738, 1259, 1351

TITLE: Pesticides on eggplant

AUTHOR: D. J. Schuster

ABSTRACT: Five insecticidal and/or miticidal chemicals were evaluated at 2
rates each on eggplant for control of mites, aphids, leafminers and
loopers. Comparisons were made with a chemical (Guthion plus Kelthane)
mixture and water check. Pesticides were applied weekly at 160-320 gal
water/acre and pest evaluations completed as their abundance occurred.
Yields of damaged and undamaged fruit were determined.
Orthene, Plictron, Pydrin, Vendex, and Vydate treatments resulted
in a low population level of Glover's and twospotted spider mites compared
to the water check. Orthene, Pydrin, and Vydate reduced the number of
green peach aphids compared to the water check. Plants sprayed with
Vydate had fewer mines produced by the vegetable leafminer than those
sprayed with water. Orthene and Pydrin reduced foliar feeding injury
due to the cabbage looper while these same compounds plus Plictran
reduced fruit injury relative to the water check. Orthene and Vydate
at rates of 2.0 Ib ai/100 gal produced marginal chlorosis and necrosis
of lower foliage.
