随着油菜面积不断扩大,连作比例提高,加上目前推广的一些新品种具有无限开花习性、花期长,易感病时期拉长,发病风险增加,有利于病菌的侵入和发病。因此,油菜菌核病的防治,每年都是一个不容忽视的问题。根据近些年高产单位防病经验,防治该病应注意抓好两点:找准用药时期、选准所用农药。 With the continuous expansion of rapeseed area and the continuous cropping proportion increase, some newly introduced varieties have unlimited flowering habits, long flowering period and prolonged susceptible period, which increases the risk of pathogens and is conducive to the invasion and pathogenesis of germs. Therefore, the prevention and treatment of sclerotinia is a problem that can not be neglected every year. According to the experience of disease prevention in high-yielding units in recent years, prevention and treatment of the disease should pay attention to two points: identify the period of drug treatment, and select the pesticide to be used.
