番茄在整个生长发育过程中可发生多种病虫害,传播速度快,发生规律复杂。近年,由于番茄产品产值高,近几年栽培茬次增多,使用农药频繁,病虫害产生了耐药性和抗药性,增大了防治难度。如果不及时防治,将会导致减产甚至绝收。因此,采用合理的防治技术对番茄生产来说至关重要。一、番茄主要病虫害1、苗期主要病虫害有猝倒病、立枯病、沤根、早疫病等。苗期虫害有潜叶蝇、蚜虫、白粉虱、烟粉虱、棉铃虫等。2、生长结果期主要病虫害
Tomato in the growth and development process can occur a variety of pests and diseases, spread fast, complex law of occurrence. In recent years, due to the high output value of tomato products, the number of cultivated stubbles has increased in recent years. Frequent use of pesticides has led to resistance and drug resistance of pests and diseases, increasing the difficulty of prevention and treatment. If not timely prevention and control, will result in reduced production or even surrender. Therefore, the use of sound control technologies is crucial for tomato production. First, the main pests and diseases of tomatoes 1, the main pests and diseases at seedling damping-off disease, damping-off, scallion root, early blight and so on. Seedling pests have leaf miner, aphids, whitefly, whitefly, cotton bollworm and so on. 2, the main growing pests and diseases results
