50%苯噻.苄对稗草具有较高的生物活性,共毒系数达135.43。田间除草50%苯噻.苄750 g/hm2,在江西省良种繁殖场药后15 d防效可达98%以上,在扬州对稗草防效为99%,对阔叶草防效为93.8%,总草防效为96.7%,可以看出其对田间多种杂草具有很好的杀灭效果。建议生产上应用50%苯噻.苄750 g/hm2于抛秧后5~7 d拌化肥或拌土撒施,可达到单双子叶杂草兼治、全程控草的目的。
50% Phenylthiobenzyl had higher biological activity against barnyardgrass with a co-toxicity coefficient of 135.43. Field herbicides 50% benzthiazole benzyl 750 g / hm2, in Jiangxi Province seed breeding field 15 days after the control effect of up to 98%, in Yangzhou barnyard grass control effect was 99%, broad-leaved grass control effect was 93.8 %, Total herbicidal efficacy was 96.7%, we can see its a variety of weeds on the field has a very good killing effect. Proposed production of 50% phenylthiobenzyl 750 g / hm2 5 to 7 days after throwing seedlings with fertilizer or mixed soil sprinkling Shi, weeds can be achieved single and double cotyledons, the whole purpose of grass control.
