日前,中国农业科学院植物保护研究所成功研制出我国第一个可防治植物病毒病的蛋白质生物农药——“6%寡糖·链蛋白可湿性粉剂”。该药剂对环境和植物本身安全、无污染,有助于农业可持续发展。植物病毒病是目前生产上危害较大、损失严重、防治困难的一类病害。据了解,该药剂通过诱导植物自身抗性,激发植物生长代谢和自身免疫系统。田间试验结果表明,该药剂对水稻条纹叶枯病的防治效果为65%,对番茄黄化曲叶病毒病的防治效果为68%。
Recently, the Institute of Plant Protection, Chinese Academy of Agricultural Sciences successfully developed China’s first protein biopesticide - “6% oligosaccharides and streptavidin WP” that can control plant virus disease. The agent on the environment and plants themselves safe, pollution-free, contribute to the sustainable development of agriculture. Plant virus disease is currently the production of a greater hazard, serious loss, prevention and treatment of a class of diseases. It is understood that the agent stimulates plant growth and metabolism and the autoimmune system by inducing plant self-resistance. The results of field trials showed that the agent had a control effect of 65% against rice stripe disease and 68% against tomato leaf curl disease.
