花生叶斑病是花生的一种常见病。近几年由于花生种植面积的扩大,重茬面积逐年增加,加剧了该病的扩散、蔓延,1985年我县种植23万亩,发病田达90％以上。但近几年来我县群众对此重视不够,误认为该病发生在花生生长后期,对产量影响不大,因此防治面积甚小。为此,我们于1985年搞了3万亩花生叶斑病防治示范试验,获得了一定的防治效果,现总结如下。 Peanut leaf spot is a common peanut disease. In recent years due to the expansion of peanut planting area, stubble area increased year by year, exacerbating the spread of the disease, spread, in 1985 my county planted 230,000 mu, the incidence of more than 90%. However, in recent years, our county people did not pay enough attention to this, mistakenly believe that the disease occurred in the late peanut growth, little impact on the yield, so the control area is very small. To this end, we engaged in demonstration of peanut leaf spot disease prevention and control of 3 million mu in 1985, obtained a certain control effect, are summarized as follows.
