title: The residual effect of imazethapyr applied in soybean to barley and winter wheat in Romania.
abstract: Many experiments have been made in Romania in the period 1965-2000 regarding the remnant effect of atrazine herbicide on different plants: barley, wheat, peas, soybean, beans, potatoes, sugar beet, flax, hemp, etc. The remnant effect of imazethapyr herbicide is similar to the effect of atrazine. Selectivity in soybean is attributed to a rapid detoxication via hydroxylation and glycosylation in the course of the days 1-6. The persistence of the imazethapyr herbicide in the soil is very long. By the dates of American Cyanamid Company, soybean, barley and wheat treated with imazethapyr can be cultivated only after 2-3 years, and sugar beet only after 4 years. Based on experiments made on chernozem soils in Romania, the conclusion that after the treatment of the soybean with imazethapyr in doses of 100-150 g/ha barley and winter wheat can be cultivated already in that autumn after the soybean harvesting, has been drawn. The results at barley and winter wheat shall be presented in this study.
