**BIOTROL, DIPEL, THURICIDE, OTHERS: Follow label directions. Low rates are for
low to medium infestations. High rates for large popuLations.
FALL WORMS: 10-12 worm species attack fall cabba.ge. Cutworms from summer cover
crops will attack cabbage as soon as it is set. Worns from corn crops tend to
bore into the head. Diamondback moth larvae and cabbrage webworms feed in the buds.
Inspect cabbage regularly. Worm damage is usually low during cold months (Jan.-Mar.)
SPRING WORIMS: imported cabbage worm and cabbage looper increase heavily during Mar.
to June. Treat weekly for best control.
50 GAL/A: Insecticides applied in 50 gpa with 1 overhead and 2 drop nozzles/row
gave an average of 15% more worm damage than 100 gpa (6 nozzles) in 4 tests. The
cabbage treated with recommended insecticide dosages in 50 gpa was marketable.
APHIDS: 2 species of aphids attack cabbage. The cabbage aphid is waxy-blue and
causes the leaves to yellow and curl. The green peach aphid is found on the under-
surface of the lowest leaves. It is light-green in color. It is the one which also
attacks potatoes. Both aphids are parasitized and killed by a small wasp which
causes them to become straw-colored and swollen. The wasp has been very numerous
the p?,t few years. Chop cabbage after harvest to slow aphid movement to potatoes.
CABBAGE SEEDBED: Chop under unneeded seedbeds to prevent aphid and worm buildup and
movement to other fields.
WRAPPER LEAVES: These leaves contain the most pesticide residues and insect damage.
Do not use an excess of them to fill out the pack.
WEEDS: Weeds interfere with insecticide coverage.
EARWIGS: These forked-tail insects are effective predators of aphids, insect eggs,
* and small insects. They are most numerous during the summer and fall. Low numbers
are present during the winter and early spring.
BAITS: Molecrickets and cutworms are most active at night. Apply baits in the late
afternoon so that it will not dry up and blow away.
