CONTROL OF INSECT PESTS OF CRUCIFERS IN THE HASTINGS AREA.
Ralph B. Workman

For the best results in producing insect-damage free cabbage and other crops
the following should be kept in mind:
1. Use spray or dust equipment which will give insecticide coverage over the
entire plant, especially, to the lower part and to the undersurfaces of the leaves
where most of the insects are found. Coverage may be determined by inspection of
the leaves after application. Insecticide application to the soil about the
plants is necessary for mole cricket and cutworm control.
2. Begin weekly applications before insect damage appears. Cabbage loopers
become increasingly difficult to control with increase in size. By the time holes
appear in the leaves, loopers are many times more difficult to kill.
3. Agitate liquid insecticides in the container by shaking or rolling before


using.

The minimum recommended dosage is adequate if properly applied.
If spreader-stickers are used, add just enough for complete coverage
appreciable runoff.
Read and observe the safety precautions printed on the insecticide label.
