The influence of soil organic matter on the initial and residual phytotoxicity of thirteen s-triazine herbicides was investigated in greenhouse experiments using three Horotiu sandy loam soils with organic matter levels of 9.8, 15.5, and 20.6%. The amount of herbicide required to reduce the growth of oats (Avena sativa L.`Mapua') by 50% (GR 5 0) when compared with the control was determined for cach herbicide and each organic matter level. Results showed that the GR 5 0 values for all herbicides were highly and positively correlated with the soil organic matter. In general, the phytotoxicity of compounds of high water solubility was less influenced by soil organic matter than those having low water solubility. The chloro-triazines persisted longer in soil thandid the methoxy- or methylthio-triazines. Simazine [2-chloro-4,6-bis(ethylamino)-s-triazinel] and atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazinel were the most persistent of the chloro-triazines. |
