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

Insecticide recommendations change frequently. Use the latest information
available. Discard old reports. Follow the safety precautions on the insecticide
label at all times. Make sure that agricultural poisons are not taken for home use.

Insecticide coverage is as important as the chemical used. Thorough coverage
means better control at less cost. Check it frequently. High dosages may leave
illegal residues on the harvested crop.

Cabbage aphids and loopers are difficult to control on older plants. Large
leaf surfaces protect aphids from sprays and systemic insecticides do not trans-
locate readily. Large leaf surfaces protect eggs, larvae, and moths of the cabbage
looper. Best coverage is needed at the inner and lower leaf area. Tro nozzles
overhead are essential.

Green peach aphids are found on the bottom leaves. Sprays for cabbage aphids
and worms will give control. Disc cabbage under after the last cutting to prevent
migration to potatoes.
