摘要

Field and pot experiments were conducted to study the persistence of pyrazosulfuron-ethyl in soil. In pot experiment, maize, soyabean, moong and sorghum were grown in succession upto three sowings at 21 days intervals at different concentrations of herbicide ranging from 0 to 0.2 ppm. Germination count, shoot height and dry weight of crops were drastically reduced at higher concentrations of herbicides in first sowing. However, in the second and third sowings differences for plant height and dry weight were less at different concentrations of herbicide indicating degradation of herbicide to safe levels. In field experiment residual carry over effects of pyrazosulfuron-ethyl applied in rice at 15 and 30 g/ha were studied using wheat, gram and pea as indicator plants. Differences were non-significant for dry matter accumulation in these plants, indicating that there was no residual effect of herbicide in soil after the harvest of rice crop.
