PULLMAN, Wash. — Washington State University Cooperative Extension’s “1997 Crop Protection Guide For Tree Fruits in Washington” has just rolled off the press.
This annual guide, which also is available electronically, offers regulatory information for growers, including application rates for chemical pesticides used on apples, pears, peaches, apricots, nectarines, cherries, prunes and plums.
Under each fruit grouping, the guide keys pesticides to specific pest or disease problems. Authors break out application information by bloom or growth stage to help orchardists pinpoint the time when pests are easiest to control. Examples of products available are included.
Efficacy of pesticides monitored in WSU research projects is provided for apples and pears. This 92-page guide also features information on hazards to bees and plants, and chemical compatibility for tank mixing.
Other sections cover weed control, nutrients, growth regulators and vertebrate pest management.
