First, the soybean virus disease Soybean virus disease is a viral disease, diseased plants dwarfed, mosaic, less pods, brown particles, affecting soybean yield and quality. Prevention and control measures: (1) do a good job in quarantine of seed, it is forbidden to transfer the poisoned seeds to the disease-free zone; (2) use resistant varieties such as Wannu 16, Hendou No. 1 and Zhongdu 20; (3) Effective control of aphids; Second, soybean cyst nematode Disease Cysticercosis is a devastating disease, commonly known as Soybean victims, less pods, beans are not full, the general cut 10% -20%, a serious cut 50% or more, or even lost. Prevention and control measures: (1) rotation. And grasses crop rotation for 3-5 years have a better disease control effect, water, drought rotation effect is better; (2) the selection of resistant and resistant varieties such as wu beans No. 16, Lu Dou 4
