Where field corn is continuously grown in a field, potential problems with corn rootworms exist. If information on corn rootworm is available to aid in making a control decision, a soil insecticide as counter or lorsban should be used at planting. If soil insects are potential problems, homeowners should consider applying diazinon granular or liquid in furrow or broadcast incorporated for their control. Soil insects may include white grubs, wireworms, corn rootworms, seedcorn maggots and cutworms. See labels for usages and precautions.
Aphids give birth to living young and populations build up rapidly.
They suck plant juices from underneath leaves and young terminals causing leaves to curl and turn yellow. These insects can build up to very high numbers and secrete honeydew causing black sooty mold to develop. They will attack most any plant grown in a garden. Insecticides as malathion or diazinon should control them. Read label restrictions.
