(seedbed) Baits Results may be erratic.
Adjust dosage for different formulations (2E, 4E, 8E, WP. Etc.)
** Do not apply more than 3 times per season.
*** BIOTROL, DIPEL, THURICIDE: Follow label recommendations. Low rates are for
low to medium infestations. High rates are for large populations.
CUTWORMS: Cutworms are usually present in the soil when cover crops are turned
under. Cabbage transplants are attacked at night following setting. Insecticide
sprays or drenches reduce the amount of injury and treatments can be applied before
plants are set. Several may be necessary for best control.
50 GAL/A: Tests this year showed that insecticides applied at 300 psi (at pump)
in 50 gal. of water per acre and with 3 nozzles per row (2 on drops and 1 overhead)
were as effective as sprays with 100 gal. and 6 nozzles. Cabbage was maintained
almost weed free so that good coverage was possible, especially on the underleaves
where most looper eggs are laid. Insect infestations were a little smaller than
usual so that the test needs repeating before recommendations can be made.
MONITOR: Monitor is now registered on cabbage and potatoes. It has been test-
ed at the ARC, Hastings for 3 years and has given excellent control of worms and
aphids. It is "phosphatic" insecticide and, while not as toxic as parathion, should
be used with care.
WORM CONTROL: Nine species of worms attacked cabbage at Hastings last fall.
Loopers and imported cabbageworm were damaging this spring. Regular preventive
sprays during heading in the fall and late spring usually give the best control as
worm populations are kept low. Control of populations after they become large
usually requires as much or more pesticide use as the regular program and the holes
remain in the plants. Sprays are often not needed during Jan.-Feb. when cool
weather normally keeps worm numbers down.
