This book was released on 2017-10-29 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Laboratory-Field Method for Testing Codling Moth Insecticides For the main experiments Grimes and Jonathan trees 19 to 23 years old have been employed. Enough trees (usually 4 to 8) are employed to provide plenty of fruit for sampling. This may run up to apples on certain plots where both biological and chemical data are to be obtained. Sprays are applied with equipment and at pressures which represent average conditions for the area, and all parts of the trees are sprayed to or slightly beyond the point where run-off begins. Spraying is done by personnel of the Division of Fruit Insect Investigations, and the man in charge actively participates. Obviously, the risk of errors in mixing and of anything less than thorough Spraying (which might introduce extreme or uncontrolled variation, thereby endangering the accuracy of all biological and chemical data subsequently collected) is somewhat lessened when he does his share of the spraying. He is then better able to interpret unexpected developments, of which there are many. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Experiments and Suggestions for the Control of the Codling Moth in the Grand Valley of Colorado Arsenate Of lime, both homemade and commercial, as used in plats VII and VIII, gave comparatively poor results. The unsprayed or check trees, plat X, were very Wormy, giving but 13. 51 per cent Of fruit free from larvae. The sprayed fruit was well protected against the calyx entrance worms except in plat VIII. With this exception, the percentage Of wormy apples infested. At the calyx in the sprayed plats varied from to The unsprayed plat produced per cent Of wormy fruit infested at the calyx.
