Book Description
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.
