1.农业防除: 深耕翻埋病菌,及时摘除病粒烧毁,建立无病种子田。田间管理注意合理施肥,氮、磷、钾肥配合施用,有机、无机肥配合,克服偏施氮肥或迟施,以减轻田间阴蔽度。浅水灌溉,干湿交替,增加植株的抗逆力,减轻病害。 2.化学药剂防治: 目前防治效果较好的药剂有复方波尔多、多菌铜粉,30%DT杀菌剂、井冈霉素等。每亩施用复方波尔多粉2.5公斤,防治效果可
1. Agricultural control: deep plowing bacteria, timely removal of particles burned, the establishment of disease-free seed fields. Field management attention to rational fertilization, nitrogen, phosphorus and potassium with the application of organic and inorganic fertilizer, to overcome partial nitrogen fertilizer or late Shi, in order to reduce field shade degree. Shallow irrigation, alternating wet and dry, increase the plant’s resistance to reduce disease. 2. Chemical control: the current good control effect of the drug compound Bordeaux, multifocal copper powder, 30% DT fungicide, Jinggangmycin and so on. Per acre compound Bordeaux powder 2.5 kg, control effect can be
