Mite Control and Integrated Pest Management: Tree Nut, Pome, Grape, and Strawberry Crops [2025]

OVERVIEW

This course discusses mite control in major crops and is sponsored by BASF. Mites are small arthropods in the class Arachnida and the subclass Acari. Although they are related to insects, mites are in the arachnid class and are closely related to spiders and ticks. They are common pests in agriculture, landscapes, and gardens. Mite species are estimated to number nearly 50,000. They live in diverse habitats; in soil, water or plant matter. They eat living and dead plant material as well as fungi, lichens, and even carrion. Some are parasites on animals and others feed on mold. This course will focus on the mites that threaten nut trees, pome fruit, grape, strawberry, tomato, and citrus crops.
