新化合物ZJ10361的除草活性研究
Study on herbicidal activity of innovative compound ZJ10361
摘要
Abstract
In order to investigate the potential application value of a novel compound ZJ10361 [1,3-dimethyl-4-(2-methyl-4-methylsulfonyl-3-(2-p-tolyloxy)ethoxy)benzoyl-1H-pyrazol-5-yl ethyl carbonate], the herbicidal activity, safety, selectivity, spectrum of weed control and field trial were studied. The result of greenhouse tests showed that ZJ10361 was safe to maize at the dosage of 150 g/hm2. However, there were some hazard to other crops. There was different safety in three maize varieties, the safety to waxy corn(Kenuo 986) was highest, that to hybrid corn(Yedan13) was the second highest, and that to sweet corn(Huazhen) is the lowest. The selectivity coefficient of ZJ10361 between maize(Zea mays) and Amaranthus retroflexus and Eclipta prostrata was 4.0-4.5, which showed that the compound had good selectivity. ZJ10361 had good herbicidal activity to broadleaf weed, and it's weeding spectrum was wider. However, it was less effective to grassy weeds and sedges. The field test results showed that at the dosage of 300 g/hm2, the compound is safe, and the total weeds controlling efficacy was 86.9%. The weed controlling was roughly equivalent to mesotrione at dosage of 225 g/hm2. The compound had potentials to be used as maize herbicide for controlling broadleaf weed.关键词
