柑桔溃疡病自1955年以来,先后在我省泸州、永川、巴县、重庆、江津、宜宾、南溪、富顺等地发现,成为柑桔生产发展的严重威胁。以往,国内外采用波尔多液、链霉素等进行药剂防治,但因效果较差,成本高、来源困难、有药害等原因,未能广泛应用。1972年在有关单位的支持下,我们对敌枯唑等63种药剂进行了室内筛选,以期寻找出一种更高效、持效期长、无药害的化学或抗菌素新农药。在此基础上,同年6月于富顺怀德果
Citrus canker disease has been found in Luzhou, Yongchuan, Baxian, Chongqing, Jiangjin, Yibin, Nanxi and Fushun in our province since 1955 and has become a serious threat to the development of citrus production.

In 1972, with the support of the relevant agencies, we conducted an indoor screening of 63 pesticides such as imazamil to find a new chemical or antibiotic pesticide that is more efficient, long-lasting and free from injury. On this basis, in June the same year in Fu Shun Hing Tak-fruit
