Book excerpt: Excerpt from European Corn Borer Investigations: Experiments With Insecticides on Early Sweet Corn This is a progress report of investigations that are not complete in all phases. The preparations employed were largely experimental, designed for use against the European corn borer, and had not been used previously in field experiments. Several of the preparations obviously lack physical properties that are highly desirable in corn borer insecticides, but some of these materials may Show considerable improvement with further develop mental research. This is particularly true Oi some of the preparations Of fixed nicotine. Preparations of derris, phenothiazine, and nicotine tannate in spray form and a dual-fixed nicotine dust provide sufficient reduction in borer populations to warrant their use in field tests to ascertain their value under commercial conditions and practice. Severe tests of weathering capacity and wash-resistance were imposed upon the materials used in these experiments. During the field experiments conducted in 1935, residues were subjected to frequent rains or light showers, and in 1936 they were again affected by the frequency and also the beavi ness of the rainfall.

Book excerpt: Excerpt from Investigations on the Control of the European Corn Borer When the eggs are deposited upon corn plants which have reached the tassel stage, the newly hatched larvae usually do not attack the tas'sel, nor do they feed to any extent upon the surface of the leaf blades; under these Circumstances they enter the stalk directly, or the thick midrib of the more tender leaf blades. If the plant has developed an ear, the newly hatched larvae frequently feed upon the tender tips of the husks and upon the silk, or work: their way down between the silks into the ear and feed upon the grain and cob.
