TREE HOPPERS AND THEIR CONTROL IN THE ORCHARDS OF THE PACIFIC NORTHWEST (CLASSIC REPRINT)

Excerpt from Tree Hoppers and Their Control in the Orchards of the Pacific NorthwestThe injury caused by the tree hoppers is due to the weakening and devitalizing effects Of their oviposition wounds on the fruit-tree twigs rather than to their feeding, which causes comparatively little damage. Most Of the oviposition scars are found on the upper sur faces Of the twigs growing from the lower branches, especially on those Which hang down into or toward the alfalfa. Little injury is found more than 6 or 7 feet above the ground. The three more harmful species cause rather distinctive types of injury, which are discussed in the order of their importance in the Northwest.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
