单分子膜物质防治植物病害研究简报

多年来,国内外主要研究和发展化学药剂防治植物病害。随着科学研究工作的深入,公害问题越来越引起人们的重视,因此,综合防治植物病害研究逐渐发展起来,尤其是生物防病和物理防病方面已取得一定进展。七十年代以来,我们在研究园艺植物病害过程中,也开展了有关物理法防治植物病害的研究,如:树皮更新(简称重刮皮)法防治苹果腐烂病,热处理法获得果树、花卉无病毒苗(木),地面铺草法防治苹果疫腐病等。现将新近试验成功的单分子膜物质防病法简要介绍如下:

A PRELIMINARY REPORT ON THE USE OF MONOMOLECULAR FILM-FORMING SUBSTANCE TO CONTROL PLANT DISEASES

The present paper briefly reports the use of a substance which forms a continous monomolecular film when applied on to the aurface of a plant part.Such film permits the exchange of gases and has a considerable elasticity,but it prevents the infection of centain plant pathogens snch as the anthracnose of apple fruits,apple rust on leaves and powdery mildews of several plants,including roses.The effectivity of such physical treatment has been demonstrated for several times in orchards and gardens in the vicin...
