1983年,在全国药效网专题协作组的统一组织下,我们在文水县开栅大队进行了粉锈宁乳油防治小麦白粉病的试验示范,同时参加试验的药剂还有45—50%硫磺胶悬剂和石硫合剂.试验结果如下.一、小区试验1.材料和方法小麦品种为晋麦8号(原名晋中849),小区面积0.02亩,随机排列,重复3次,小区间隔0.5米。粉锈宁分为每亩有效成份4克和8克两种,硫磺胶悬剂100倍,石硫合剂波美1度,每亩次喷稀释液120斤。粉锈宁设喷1次和2次两种处理.喷1次的在小麦孕穗期进行,喷2次的为拔节末期和孕穗期;已硫合剂和硫磺胶悬剂各喷3次,分别在拔节末期、孕穗期和抽穗期.以同时喷清水作为对照.药效调查在末次效药后第10天进行,施药前调查发病基数,每处理定100株,每株查上部3片叶.
In 1983, under the unified organization of the national collaborative team of the efficacy net, we carried out demonstration trials of triadimefon against wheat powdery mildew in the open-gate brigade in Wenshui County. At the same time, 45-50% Agents and lime sulfur mixture.The test results are as follows.Area test 1.Materials and methods Wheat varieties Jinmai 8 (formerly known as Jinzhong 849), the plot area of 0.02 acres, randomly arranged, repeated 3 times, the interval of 0.5 meters. Triadimefon is divided into active ingredients per acre 4 grams and 8 grams of two, 100 times the sulfur suspension, stone sulfur mixture Bomei 1 degree per mu diluted spray 120 pounds. Triadimefon was sprayed once and twice in two treatments, sprayed once in wheat booting stage, sprayed 2 times for the last stage of jointing and booting stage, sulfurous agent and sulfur suspension were sprayed for 3 times, respectively, at the end of jointing , Booting stage and heading stage.At the same time spraying water as the control.Pharmacological efficacy survey was carried out on the 10th day after the last dose, and the incidence of disease was investigated before application, with 100 plants per treatment and 3 leaves per plant.
