1964年河南省农业科学院植保所和许昌专区农科所合作,在河南省农业厅的大力支持下,进行了药剂防治小麦条锈病的大田示范。 这个示范设计主要针对以往小区试验已经确定成效的对氨基苯磺酸,进行大面积防治,以期进一步肯定它在生产上的应用价值。同时结合观察常州氟钡、醋酸镍、闽衣五号三种农药的实际效果。 1964年条锈病在河南省各地是继1959年和1960年大发生后的再一次猖獗,在碧码一号小麦上发病普遍率大部为100％。严重度达65—80—100％,病情指数达80％左右,这对测定药剂效果是比较可靠的。
In 1964, Henan Academy of Agricultural Sciences plant protection and Xuchang area of agricultural cooperation, with the strong support of the Department of Agriculture in Henan Province, carried out pesticide stripe rust wheat field demonstration. This demonstration design mainly aimed at the sulfanilic acid, which has been confirmed in the previous plot test, has been carried out in large scale to further confirm its application value in production. At the same time observe the actual effect of three pesticides Changzhou fluorine barium, nickel acetate, Fujian Yi on the 5th. In 1964, stripe rust was once again rampant in various parts of Henan Province, following the great occurrences of 1959 and 1960, with the prevalence rate of 100% prevailing in Bi-yi-1. The severity of 65-80-100%, the disease index of about 80%, which determine the effect of agents is more reliable.
