稻曲病在我区自1980年以来逐年加重,已遍及全稻区,不仅使水稻减产,菌粉还污染稻谷,降低商品价值。稻糠含菌粉量高,对牲畜发育也有一定影响。1983～1985年进行了药剂防治试验。筛选出高效农药多菌铜粉剂。找出了最佳施药期和经济用量。在小区试验的基础上,又做了大面积示范,取得了显著防治效果。一、试验处理小区面积为20～30平方米,3次重复,顺序排列。选上年发病重,排灌方便的田块。品
STD has been increasing year by year in our region since 1980 and has spread throughout the whole rice region. It not only reduces the output of rice, but also pollutes the rice and reduces the value of the commodities. Rice bran containing high amount of bacteria, livestock development also has a certain impact. 1983 ~ 1985 conducted a chemical control test. Filter out highly effective pesticide multifungi copper powder. Find out the best application period and economic usage. Based on the plot test, a large-scale demonstration was made and significant prevention and control effects were achieved. First, the experimental area of 20 to 30 square meters, 3 times repeated, in order. Select the incidence of the previous year, irrigation and drainage convenient plots. Product
