Abstract

Addition of organic matter reduced the effectiveness of 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine) to oats in Regina heavy clay soil. At high moisture levels, changes in the relative amounts of clay in the soil did not affect the toxicity of simazine. Toxicity of simazine decreased as the soil moisture level was reduced.
