花生线虫病是我区花生生产上的一种毁灭性病害。据不完全统计,我区发病面积达一百多万亩,历年因病减产花生果达一亿斤左右。因此,消灭这一病害,是花生生产上的重大问题。 通过一九六四年至一九七二年试验示范推广,证明二溴氯丙烷是防治花生线虫病的特效药。一般每亩施药四斤,其防治效果在百分之九十五左右,每亩增产荚果一百斤以上。这两年我区共用二溴氯丙烷二百六十吨,防治面积达十五万亩,增产花生果一千五百万斤,该药剂在实践应用中深受贫下中农欢迎。但据我们调查了解,各地在使用二 Peanut nematode disease is a devastating disease in peanut production in our district. According to incomplete statistics, the disease area in our district reached more than 1 million mu and peanut fruit up to one billion kilograms was reduced over the years. Therefore, the eradication of this disease is a major issue in peanut production. Through pilot demonstration and promotion from 1964 to 1972, it was proved that dibromochloropropane is a cure for peanut nematode disease. The general application of four pounds per mu, its control effect in about 95 percent, more than one pound per acre yield pods. In the past two years, our district shared two hundred and sixty tons of dibromochloropropane, with a control area of ​​150,000 mu and an additional peanut fruit yield of 15 million kg. The pesticide was welcomed by poor and middle peasants in practical applications. However, according to our investigation, two are used everywhere
