豌豆立枯病又称豌豆基腐病,是豌豆的一种重要病害。主要发生在苗期。种子发病,造成烂种。子叶染病,产生红褐色近圆形病斑。受害幼苗茎基部产生红褐色椭圆形或长条形病斑,病斑继续扩展到整个幼茎基部时,幼茎逐渐萎缩、凹陷,当扩展到绕茎一周后,病部收缩或龟裂,导致幼苗生长缓慢,最后枯死,有时折倒。湿度大时长出浅褐色蛛丝状霉。防治方法:发病初期,先拔除病苗,带出田外深埋,然后喷铜氨合剂(硫酸铜0.5千克加5升氨水混匀),防止蔓延。或选用5%井冈霉素水剂1500倍液、72.2%霜霉威水剂800倍液、20%甲基立枯磷乳油1200倍液、36%甲基硫菌灵悬浮剂500倍液、
Pea blight, also known as pea-based rot, is an important pea disease. Mainly occurs in seedling stage. Seed disease, causing rotten species. Cotyledonary disease, resulting in nearly brownish red spot disease. The damaged seedling stem base produce reddish brown oval or strip-shaped lesions, lesion continues to extend to the entire base of young stems, young stems gradually shrink, depression, when extended to around the stem a week, the disease shrinks or cracks, resulting in Seedlings grow slowly, finally dead, and sometimes collapsed. When the humidity is long brown spider mites filamentous mold. Prevention and treatment methods: early onset, first remove the disease vaccine, out of the field buried, and then spray copper ammonia mixture (copper sulfate 0.5 kg plus 5 liters of ammonia mix) to prevent the spread. Or choose 5% Jingdongmycin 1500 times liquid, 72.2% Mildew 800 times, 20% methyl triflate EC 1200 times, 36% thiophanate-methyl 500 times,
