Plant the garden in full sun and make sure that plants have adequate moisture, nutrients, and spacing for maximum growth and production. Insect Control Insects are always a threat to home vegetable gardens. The gardener must check plants frequently to detect the presence of injurious insects and be ready to control them as soon as damage is evident. When checked frequently, many garden insects can be controlled successfully without the use of insecticides. No single chemical will protect plants from all of these pests.
Many insecticides are available today.
Insecticides should be selected with care and chosen with a specific pest in mind. Common insecticides for home garden use are available in synthetic, botanical, biological, and mineral-based formulations. Biological controls are a good option, particularly for caterpillar pests. Other materials homeowners may use for insect control include diatomaceous earth, oils, and soaps. Insects that live in the soil and damage roots and underground portions of the stems cannot be effectively controlled by treating the above ground portions of plants.
