83增抗剂是在植物病理专家裘维蕃教授指导下研制成功的第一例植物耐病毒诱导剂。是根据植物诱导抗性的原理,采用人工免疫的方法,以提高植物抗病力为主,兼有促进植物生长,抑制介体传毒的一种多功能的防治病毒病制剂。对蔬菜、烟草、瓜类、果树、糖料、人参等多种植物病毒病有防病增产效果,平均防效59%左右,增产效果瓜菜平均为20%,烟草为10%。每亩投入4—6元,增收12倍以上。83增抗剂无毒、无公害、无污 83 enhancer is the first case of plant virus-resistant inducer successfully developed under the guidance of Prof. Vivian Chiu, a plant pathologist. Is based on the principle of plant-induced resistance, the use of artificial immune approach to improve the plant disease-resistance-based, both to promote plant growth, inhibit mediator poisoning a multi-functional anti-virus disease agents. On the vegetables, tobacco, melons, fruit trees, sugar, ginseng and other plant disease virus disease prevention and increase production, the average control effect of about 59%, yield an increase of melon average 20%, tobacco 10%. 4-6 yuan per mu, an increase of 12 times more. 83 enhancers non-toxic, pollution-free, non-polluting
