近年来,防治小麦白粉病多采用特效药粉锈宁。但因药源不足、成本较高,在生产上不易被普遍接受。1984—1986年,本所及有关县11个点的室内及田间试验示范结果均表明,粉锈宁与氟硅脲减量混用的防治效果与粉锈宁常量单用时相仿,而持效期有所延长。其中“10％氟硅脲膏剂250克/亩+20％粉锈宁乳油10毫升/亩”是一种防治小麦白粉病较理想的混用配方。
In recent years, the prevention and treatment of wheat powdery mildew and more use of special medicine powder rust Ning. However, due to lack of sources of drugs, the higher the cost, it is not easy to be generally accepted in production. In 1984-1986, the indoor and field pilot demonstration results at 11 points in both the Stock Exchange and the relevant counties showed that the preventive and curative effect of the combination of triadimefon and flufenoside was similar to that of triadimefon at a single dose, and the persistence period was prolonged. Among them, “10% fluosilicate paste 250 g / mu + 20% triadimefon 10 ml / mu” is a kind of mixed wheat powder mildew prevention ideal combination formula.
