abstract

The Pacific spider mite and the Willamette spider mite are the most common mite pests on grapevines. A single-season study of a vineyard near Madera showed that regular sulfur applications for powdery mildew control can exacerbate spider mite problems in vineyards by suppressing populations of predatory thrips and predatory mites.
