稻曲病是我县水稻产区的主要病害之一。近几年来,我们开展了防治稻曲病的研究工作,为了进一步提高防治效果,探索准确的防治时期,我们在筛选出防治稻曲病的高效农药基础上,进行防治稻曲病的适期试验,取得了显著防治效果。去年我们在本县邵二台乡青堆子村和大河南乡前二台子村进行了稻曲病的防治,采用辽化宏伟化工厂生产的10％胶铵铜溶剂,水稻品种是辽粳5号。试验结果表明,8月3日施药的防效最佳,穴防效为78.2％,穗防效为93.6％,粒防效为96.1％。通过去年的试验和近几年防治稻曲病的经验,我们认为:
False germ is one of the major diseases in the rice producing area of our county. In recent years, we conducted a research work on the prevention and control of rice false smut in order to further improve the control effect and explore the exact period of prevention and control, we filter out the control of smut based on efficient pesticides on the control of smut , Achieved a significant control effect. Last year, we conducted prevention and control of rice false smut in Qingdaizi Village, Sha’er Taitai County, and Qian’erzitai Village, Dahe Nan’en Township. We used 10% ammonium gluconate as solvent in Liaowu Hongwei Chemical Plant. The rice variety is Liaojing 5 number. The test results showed that the best anti-drug effect was applied on August 3, with 78.2% of control points, 93.6% of spike prevention and 96.1% of control effect. Through the experiments of last year and the experience of prevention and control of rice false smut in recent years, we think:
