Spider mites (Tetranychus spp.)
Their feeding causes tiny yellow or white speckles, eventually leaves become yellowish and may drop, and may led to complete defoliation. Heavily infested plants may become stunted. A heavy infestation might also cause vine dieback and shrivelling and dropping of immature fruit.
- Field hygiene is important for the management of spider mites. Old crops or weeds infested with mites can cause infestation of new crop.
- Natural enemies such as predatory mites are important for control of spider mites.
