| الوصف: | Field research was conducted in Berrien County, Michigan, during the summer of 1967 on several aspects of oat productivity effected by feeding damage of a large population of Oulema melanopus (L.). Various degrees of population control were achieved with granular carbofuran applied as a broadcast soil-surface treatment before egg hatching started and single or double sprays of malathion applied at time of peak larval numbers. A 3 lb per acre rate of carbofuran maintained cereal leaf beetle-free plants. Untreated plots showed a grain yield reduction of 48.8%, or 4.7% per larva per stem for each of the 10.4 larvae per stem. Other maximum reductions were an additional 3.3% in 1/13 inch screening losses. 14.6% in plant height, 14.2% in kernel weight, 40.9% in kernel number, and 30.2% in straw weight. Early application of 1 or 3 lb of carbofuran per acre provided seasonlong control. |
