葡萄根瘤癌肿病是一种较难治愈的细菌性病害.过去,我们果园巨峰品种患病率为6—25%,玫瑰香患病率为41.7%,给生产造成一定的损失.1988年,我对此病采用刮治和涂药的方法进行防治,收到了治愈率75.5%的效果.刮治葡萄根瘤癌肿病在7月份进行,刮治时,用果树芽接刀(刮刀或修枝剪也可)在好皮与肿瘤之间下刀,切口和剖面要平滑,刮治深度至木质部为止.将肿瘤全部刮除后,立即在伤口处涂上石灰硫磺合剂(波美28度).对刮下来的皮屑要集中拿到园外烧掉,刮治的工具要经常用酒精消毒,以免传染其它植株.感病严重的植株应及时全株刨掉.此外,对外引的插条、幼苗要进行严格的检疫,栽植前进行消毒处理.
Grape root nodule cancer is a more difficult to cure bacterial diseases.In the past, the prevalence of our orchard Kyoho species is 6-25%, the prevalence of Muscat rose 41.7%, resulting in some loss of production.In 1988, I cure this disease with the method of cure and cure, received a cure rate of 75.5% effect. Scrape and cure grape root tumor tumor in July, scraping, the fruit bud pick knife (scraper or pruning shears Can also) between the good skin and the tumor under the knife, the incision and the section should be smooth, cure the depth to the xylem so far.All the tumor after curettage, immediately coated with lime sulfur in the wound mixture (Baume 28 degrees) Scraping the shavings to get concentrated outside the park to burn, scraping the tools to be regularly disinfected with alcohol, so as not to infect other plants.
