花生病毒病是影响我国花生生产的重要病害,自七十年代初以来趋于严重。由于我国三种主要花生病毒均为种传病毒,其传毒介体蚜虫在田间发生早、发生量大,致使我国花生病毒病具有发生早,发病率高的特点,而且流行范围广,造成损失严重。近年来花生种植面积扩大,估计常年花生病毒病流行为害面积约3000万亩左右,年损失花生25万吨以上。
Peanut virus disease is an important disease that affects peanut production in our country and has tended to be serious since the early 1970s. As the three major peanut viruses in our country are virus-type viruses, the aphids of the virus-mediated mediators occur early and occur in the field, resulting in the occurrence of peanut virus diseases in our country with high incidence and early peanut virus disease, and the widespread epidemic caused losses serious. In recent years, the peanut planting area has expanded. It is estimated that perennial peanut virus disease epidemic area is about 30 million mu and annual peanut loss is over 250,000 tons.
