1.农业防治选择适合当地生产的高产、抗病虫、抗逆性强、品质好的优良胡萝卜品种。在田间管理上,实行包括豆科作物或绿肥在内的至少两种作物进行轮作倒茬。在地下水位高、雨水多的地区采用深沟高畦,利于排灌,保持适当的土壤湿度,对防止和减轻病害具有较好的作用。清洁田园,消除病株残体、病胡萝卜和杂草,予以集中销毁或深埋,以切断传播的途径。采取深翻晒土、床土消毒、种子消毒、合理密植、配方施肥等农业措施,提高植株的抗病能力。高温季节,利用换茬时期覆盖塑料地膜进行土壤消毒,能有效杀灭部分病虫害。2.物理防治采用物理诱杀或驱避害虫,如用黄板诱杀
1. Agricultural control Choose suitable for local production of high yield, pest resistance, resistance, good quality good carrot varieties. In field management, at least two crops, including leguminous crops or green manures, are cropped and rotated. In the high groundwater level, rainy areas with deep ditch talus, irrigation and drainage, maintaining proper soil moisture, to prevent and reduce disease has a good effect. Clean the garden, eliminate diseased plants, sick carrots and weeds, to be destroyed or buried deeply in order to cut off the route of transmission. To take the deep turning the soil, bed soil disinfection, seed disinfection, reasonable close planting, fertilization and other agricultural measures to improve plant disease resistance. Hot season, the use of stubble cover plastic film for soil disinfection, can effectively kill some pests. 2. Physical control using physical or kill trapping insect pests, such as the yellow board to kill
