Evaluation of Synergized Pyrethrum for the Protection of Stored Wheat and Shelled Corn From Insect Attack - Softcover
Synopsis
Excerpt from Evaluation of Synergized Pyrethrum for the Protection of Stored Wheat and Shelled Corn From Insect Attack<br/><br/>The studies were conducted on wheat and shelled corn stored on Commodity Credit Corporation, U. S. Department of Agriculture bin sites in rectangular, wooden bins of a rated capacity of 3, 200 bushels, and in standard circular metal bins of a rated capacity of 3, 250 bushels. After the protective treatments were applied, the grain was sampled monthly to determine levels of insect population and moisture content, and quarterly for chemical residue analyses, bioassay tests, and commercial grade. Various formulations of pyrethrins and a synergist were applied to wheat and shelled corn. The pyrethrins content of these formulations ranged from 0. 89 to 2. 50 p. P.m. (parts per million), with the synergist usually in the ratio of 1 to 10. Tests were also made with the ratio 1 to 5, with the synergist alone, and with pyrethrins alone.
