CABBAGE INSECT CONTROL IN THE HASTINGS AREA
R. B. Workman, Assistant Entomologist /

Tests of 13 insecticides at the Potato Investigations Lab last season showed that
the best treatments for cabbage loopers were parathion at 8 oz. and parathion at 4
oz. plus toxaphene at 16 oz. actual per acre. When loopers are numerous, especially
when the cabbage is heading, insecticides must be applied weekly for effective
control. During the colder part of the season, insecticide applications every 2
weeks or when insects are present will give adequate protection. Application is
very important. Thorough coverage is a must with particular attention to the under-
sides of the bottom leaves and to the inner leaves when cabbage is heading. Six
nozzles per row are recommended--2 overhead, 2 laterally, and 2 below the plants.
Double dosages are not necessary with good application. If dosages are increased,
the interval before harvest must he extended to eliminate residues. Enulbible
insecticides only are listed in the table. If other concentrations or formulations
are substituted, adjust the amount specified accordingly.
Follow the safety precautions on the insecticide label at all times. Do not leave
insecticides within reach of irresponsible persons.

Do not apply endrin or toxaphene to broccoli or cauliflower after edible parts
begin to form.
