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。
This article concisely reports the results of ramie anthracnose prevention and control research. After the harvesting of the first crop of tamarind, combined with land reclamation, 75 kilograms of lime was applied per acre and the control efficiency reached 57.42% -76.98%. Among the tested pesticides, the control effect of 40% double-wettable powder was the best, followed by 70% thiophanate-methyl wettable powder and 40% carbendazim wettable powder, Seed dressing double effect increased with the increase of concentration to 250 to 500 times the liquid is appropriate. In the initial ramie season growth (height 30cm or so) should begin spraying, anthrax at this time is still in the early stages of disease, after every 7 to 8 days to apply 1, 2 to 3 times a quarter of linen to apply 2 to 3 times the drug can be obtained Ideal effect 40% seed dressing ramie double prevention and treatment of anthrax, field control in the demonstration, and the plot test control effect is basically the same.
