1955年室內和大田噴撒石灰粉的防治試驗結果說明,在雨后天晴的情况下噴撒石灰粉有一定的防治效果。 1958年春曾进行了1007亩(其中对照239亩)种子消毒的防治試驗。用0.5％的西力生或賽力散燜种3小时,或用0.2％西力生浸种12小时,种子发芽率不受影响,苗期发病率显著降低,大田发病日期稍为延迟,发病严重度大为減輕。 1956—1957年早晚季連續四次(每次試驗面积100亩以上)进行换用无病田种子及剷除李氏禾杂草的大田防治試驗,防治結果都很好。1958年春季在从化县街口公社国星大队成功地完成了大面积(3600亩)的防治示范試驗,全部不发病。但是,李氏禾是否本病的野生寄主,剷除李氏禾在防治上是否必要,尚有不同看法,有待进一步研究。
1955 indoor and field spray limestone prevention and control test results show that in the case of fine spray after spraying a certain lime control effect. In the spring of 1958, 1007 mu of which (control 239 mu) seed disinfection prevention and control tests. Seeds were sowed for 3 hours with 0.5% silymarin or salamander, or soaked with 0.2% silymarin for 12 hours. The seed germination rate was not affected, the seedling incidence was significantly reduced, the onset date of the field was slightly delayed, and the severity of the disease Greatly reduced. 1956-1957 early morning and late season for four consecutive times (each test area of more than 100 acres) to switch to disease-free field seeds and eliminate Lee weeds grass field control test, the control results are good. The spring of 1958 in Conghua County Jiekou commune brigade successfully completed a large area (3600 acres) prevention and control demonstration pilot, all without disease. However, Lee Wo whether the wild host of the disease, the elimination of Lee Wo Wo in the prevention and control is necessary, there are different views, pending further study.
