随着易感染稻曲病品种的推广,加上不良气象及不合理的高肥水栽培管理的影响,致使稻曲病发生逐年严重(我县21万亩水田,发病面积达7.02万亩),成为水稻生产上的一个主要病害之一。它不仅影响产量,而且对人、畜健康为害甚大。去年,我们从沈阳化工研究院引进了40％薯瘟锡在大田、大刘、夹河、莲山等乡(镇)农科站进行防治稻曲病试验,各点试验效果一致,防治效果为87—98.8％,平均防效为92.5％。而多菌铜防治效果为
With the popularization of varieties of susceptible to smut and coupled with the adverse weather and irrational high-fertilization cultivation and management, the incidence of smut was year by year serious (21 million mu of paddy fields in our county with a disease area of 7.02 million mu) One of the major diseases in rice production. It not only affects production but also causes great harm to human and livestock health. Last year, we introduced 40% of potato plague tin from the Shenyang Chemical Research Institute to prevent and treat rice false smut in the agricultural stations of Datian, Daliu, Jiahe, Lianshan and other towns (towns), and the results of the tests were consistent at all points. The control effect was 87-98.8%, the average control effect was 92.5%. The bactericidal effect of copper control
