Title: Studies on safety of sulfonylurea herbicides to maize and degradation dynamics in soil
Abstract: Studies on the methods of indoor modeling addition and pot culture showed that there was different sensitivity of different maize varieties to 3 kinds sulfonylurea herbicides. The concentration of 3 kinds of sulfonylurea herbicides beyond ED 10 had obvious effect on length of roots, height of plant, area of leaves in maize seedling. The half life of tribenuron, thifensulfuron methyl and bensulfuron methyl was 3.6 d, 6.3 d,15.4 d respectively. Under the application dose that used in the wheat field,only the tribenuron methyl among 3 kinds of sulfonylurea herbicides resulted in damage to the next maize crop.
