Disease Control Squash is subject to damage from nematodes and diseases. The most destructive insects on summer squash are cucumber beetles, squash bugs, and squash vine borers. Pickleworms, melonworms, and aphids can also become problems if not controlled. Consult Extension Publication 554 for control measures. Spray for insects when bee activity is minimal.
Bees are essential for pollination.
Pollination Bees transfer pollen from the male flowers to the female flowers. The first several flowers are male, so do not expect fruit from them. One hive per acre placed near the squash field will furnish enough bees for pollination. Harvest before the glossy appearance is lost. Harvest zucchini when fruits are 6 to 8 inches long.
