abstract

Not available – first paragraph follows:

Control of spider mites attacking the foliage of apples and pears is one of the most important pest control problems that confronts the northern California orchardist. Though much attention has been given to this problem by field research men and many new acaricides have been available for field tests, a satisfactory control has not been obtained in many orchards.
