| 摘 要： | 本文简明报道了苎麻炭疽病防治的研究结果:头麻收获后,结合中耕复土,每亩施用石灰75公斤,防效达57.42％～76.98％。在供试的农药中,以40％拌种双可湿性粉剂防效最好,70％甲基托布津可湿性粉剂和40％多菌灵可湿性粉剂次之,瑞枯霉防效较差,拌种双的防效随浓度的增加而提高,以250～500倍液为宜。在当季苎麻生长初期(苗高30cm左右)应开始施药,此时炭疽病尚处于发病初期,以后每隔7～8天施用1次,每季麻以施用2～3次药即可获得理想效果。40％拌种双防治苎麻炭疽病,在大田防治示范中,与小区试验防效基本一致。

Studies on the Control of Ramie Anthracnose |

| Abstract: | This paper deals with the control of ramie anthracnose. The results from plot trials showed, it gave a control effect of 57.42% that 75kg/ mu of lime was dusted to fields during intertiliage practice after reaping ramie. Of the fungicides evaluated, Banzhongshuan showed the highest activity against the diseases, and 70% Wp Mildothane and 40% Wp Bavistin were the next. Ruigumei was not good as the control agent. Benefit was achieved with the increase if Banzhongshuan concentration. The concentration sprayed should be from 800 to 1600 ppm a.i. At the early stage of ramie growth (plant height about 30 cm) when the ramie began to be infected with the disease, the fungicide should be used , and then sprayed 2-3 times at a 7-8 days interval. Banzhongshuan was also tested to be highly effective for the disease control in field trials . |
