We recommend you use a pyrethoid tag for only one year and a phosphate tag for one to two years. Plan ahead for your fly control strategy. Insects seldom threaten to destroy all the plants in a greenhouse, but they can reduce the number of useable plants produced. Insect pests may also be carried on transplants from the greenhouse to the field, where they are more expensive to control. Slugs may be very damaging especially during cool, rainy springs.
Slugs have soft, legless, unsegmented, gray-brown bodies.
The body glides along on a mucous secretion which gives slugs their slimy appearance. They feed at night, tearing ragged holes in the leaves. They may be found under debris, planks, etc. Cutworms feed primarily at night or on cloudy days. They cut off small plants just above the soil surface and occasionally cut off individual leaves.
