为了寻找防治小麦条锈病的经济安全有效的新农药,近两年来,我们利用过磷酸钙磷肥厂副产物氟硅酸及其与脲素复合制成的氟硅脲,开展了防治小麦条锈病的多点药效试验和大面积示范。根据29个县、130万亩的试验示范结果,氟硅酸、氟硅脲防治条锈病的效果是完全可以肯定的。氟硅酸、氟硅脲的来源广,凡是生产过磷酸钙磷肥厂的地方,都可进行回收,就地利用,有利于减轻排放酸硅胶及含氟尾气对环境和水域的污染。成本很低,每亩次平均氟硅酸成本不到0.10元,氟硅脲不到0.20元,而敌酸钠则需0.40元多。残效期长,一般在10—15天。还有一定的肥效作用,氟硅脲尤其明显,比对照增产3%以上。经过现场评比,开会总结,一致认为应当作为我省近期内防治小麦条锈病的当家农药,大力抓好推广使用:
In order to find a new safe and effective pesticide against wheat stripe rust in the last two years, we have used fluosilicic acid, a by-product of the superphosphate fertilizer plant, and flufenoside, a compound of urea and silicate, to control wheat stripe rust Multi-point efficacy test and large-scale demonstration. According to the results of the pilot demonstration of 130 mu in 29 counties, the effect of fluosilicate and flusesudil against stripe rust is completely certain. Fluorosilicic acid and fluvaluron are widely sourced. Wherever they are produced, they can be recycled and used locally to reduce the environmental and water pollution caused by the discharge of acid silica gel and fluorine-containing tail gas. The cost is very low. The average cost of fluorosilicic acid per acre is less than 0.10 yuan, less than 0.20 yuan for fluroxysureas and 0.40 yuan for sodium peroxides. Long residual effect, usually 10-15 days. There is also a certain effect of fertilizer, fluvastatin is particularly evident, more than 3% increase compared with the control. After on-site appraisal, the meeting concluded that they agreed that the province should be as early as the control of wheat stripe rust pesticides, vigorously promote the use of:
