Abstract: Influence of soil environmental factors on herbicidal activity of ZJ1835 N-(2-chlorine-6-(4,6-dimethoxy pyrimidine-2-oxygroup) benzyl) aniline was carried out by traditional bioassay methods. The results showed that all the factors have an effect on activity of ZJ1835, including soil texture, pH value, organic matter content, moisture and temperature. ZJ1835 had higher activity in sand soil and clay soil than in loamy soil. The activity would enhance with increasing of the organic matter content, pH value and moisture of soil. There was no obvious positive or negative correlation between activity of ZJ1835 and temperature. It would be suggested that the reasonable range of temperature for the herbicidal activity of ZJ1835 was 15 ℃ to 25 ℃.
