To prevent powdery mildew, ensure adequate air circulation around the plants by providing enough space between them. Additionally, avoid watering the foliage and instead focus on watering the base of the plants.

Squash Vine Borer

The squash vine borer is a destructive pest that can cause extensive damage to zucchini plants. The adult moth lays eggs on the stems, and the larvae tunnel into the plant, causing it to wilt and eventually die. To deter squash vine borers, protect the base of the plants with row covers or use biological controls, such as beneficial nematodes or parasitic wasps.

Cucumber Beetle

Cucumber beetles are common pests that can transmit bacterial wilt and cause damage to zucchini plants. They feed on the foliage, flowers, and fruit of the plants. To control cucumber beetles, introduce natural predators like ladybugs and lacewings to your garden. You can also use floating row covers to physically exclude the beetles from the plants.
