Abstract
Soil carry-over of atrazine following annual applications to a sorghum monoculture was studied by assessing sorghum yield factors as well as yields of a subsequent bioassay crop of oats. Atrazine applications of 3.4 kg/ha or more increased sorghum injury and rates of 4.5 kg/ha and more increased seed weight and decreased stand. Sorghum recovered from early atrazine injury and stand loss and generally maintained yields. Rates of 2.2 kg/ha did not reduce sorghum yields even with repeated annual usage. There appears to be little risk of reducing sorghum yields due to atrazine carry-over in the soil from annual atrazine applications made at normal rates to a clay loam or silty clay loam soil in eastern Nebraska. However, atrazine carry-over will have to be a consideration if the grower plans to rotate to a susceptible crop such as oats. From summary
