** 3IOTOL, DIPEL, THURICIDE: Follow label recommendations. Low rates are for
low to medium infestations. High rates are for large populations.
FAIL ,OR!r,9S: 10-12 worm species attack fall cabbage. Some cutworms antd ar. Tyorms,
coming from sunner cover crops, tend to feed in the bud or head. Regular inspect-
ion and treatment of cabbage during budding to heading will reduce worm injury.
WINTETR WORMS: Cool temperatures from Jan. to "ar. reduce worm species, numbers, and
feeding. Insecticide applications can be reduced if regular inspections show low
worm numbers or recent damage.
SPRITNG WORMS: Cabbage loopers and imported. cabbage worms are the predominant worms
on cabbage from Har. to June. Cabbage loopers are very difficult to control and
develop high populations on cruciferous crops. Weekly insecticide applications
are necessary to produce damage-free cabbage.
WRAPPER LEAVES: Pesticide residues, cut off interval before harvest, insect damage,
and shipping costs could be reduced with fewer wrapper leaves on the head.
50 GAL/A: 3 year's tests show that insecticides applied at 300 psi in 50 gal. of
water per acre and with 3 nozzles per row, 1 overhead and 2 drops, were nearly as
effective as sprays with 100 gpa and 6 nozzles. Sprays should be put on regularly
when worms are present. Heavy weed growth will limit best coverage of the under-
leaves where most insect eggs and small larvae are found.
COVERAGE: For best insect control, sprays should contact both sides of the leaves
with an even deposit. Check equipment by spraying 50 feet of row, then, inspect
the plants and make nozzle adjustments as necessary.
PESTICIDE SHORTAGE: Some pesticides may be unavailable this season. Growers should
test different pesticides on a small areaato obtain firsthand knowledge of the effec-
tiveness of a material as used under their particular method of application. Keep
records of pesticides used, application rate, insect damage, weather conditions,
yields, etc. Use only pesticides registered for the crop.
