近年来,随着柑桔生产的发展,柑桔锈壁虱也大量发生,不仅影响果实的质量,而且影响产量。过去常用石硫合剂防治,总是不能很好地控制它的危害。今年,湖南邵阳地区园艺场的革命职工和科技人员,在伟大领袖毛主席“同病虫作斗争”的教导下,用代森锌防治锈壁虱,获得了良好的效果。 In recent years, with the development of citrus production, citrus rust ticks also occur in large quantities, not only affecting the quality of the fruit, but also affect the yield. Stone sulfur mixture used to control the past, always can not properly control its harm. This year, revolutionary workers and scientists and technicians from the horticultural market in Shaoyang, Hunan, under the guidance of Chairman Mao’s “fight against pests and diseases”, took control of rust ticks with dexmedetans and achieved good results.
