苹果树腐烂病(Valsa mali)发病因素复杂,病原菌具有潜伏侵染特性,很难杜绝。目前对病树大多采用“刮治”办法,虽有一定的防治效果,但技术要求严格,稍有疏忽,可造成病疤复发,而且工效很低。 为了寻求高效低毒农药和简便易行的防治方法,用“11371”发酵液(一种微生物抗生素,辽宁省微生物研究所提供),采取“割条”涂药的方法,收到了较好的效果。 大田防治试验用“11371”原液,以砷平波作为对照药剂;施药方法采用“割条”涂药, Apple tree rot disease (Valsa mali) complex pathogenesis, pathogens have latent infection characteristics, it is difficult to eliminate. At present, most of the disease tree “scraping” approach, although a certain control effect, but the technical requirements of a little negligence can cause scar recurrence, and the work efficiency is very low. In order to seek efficient and low toxic pesticides and easy control methods, using “11371” fermentation broth (a microbial antibiotic, provided by Liaoning Institute of Microbiology) . Field control test with “11371” stock solution, arsenic flat wave as a control agent; application method using “cutting bar” coating,
