玉米丝黑穗病(Corn head Smut)是由病菌(Sphacelotheca reiliana Ckhu)Clinton 系统.侵染的病害.它的侵染期很长,自种子萌芽至幼苗长到7张叶片,均能发病,因此用常规杀菌剂拌种保护无效.我国自1979年之后,曾大力筛选内吸杀菌剂,如:多菌灵、托布津、萎锈灵、拌种灵、禾穗胺及三唑类内吸杀菌剂;在80年代初确认粉锈宁和羟锈宁拌种效果较好,是当时防治此病有效的措施,并于1983年建议在生产中推广每百公斤玉米拌粉锈宁有效成份80克的措施.据多年试验、示范和生产使用证明,粉锈宁拌种的效果在重病田较差;随年度、地点、
Corn head Smut is a disease caused by the infection of the Clinton system of Sphacelotheca reiliana Ckhu and has a long period of infestation, which can occur from seed germination to seedling growth up to 7 leaves. With conventional fungicide seed dressing protection is invalid in our country since 1979, has strongly screened endotrophic agents, such as: carbendazim, Topazin, atrophy rust, seed dressing spirits, Woosui amine and triazole fungi In the early 1980s, it was confirmed that the combination of triadimefon and trimethoprim was effective, which was an effective measure to prevent and treat the disease at that time. In 1983, it was suggested to promote the production of 80 grams of the active ingredient of trimetazidine Years of testing, demonstration and use of production proved that the effect of powder rusting seed dressing worse in severe disease; with the annual, location,
