室内测定表明：益菌Ｂ０１７可抑制褐斑病孢子的萌发；在ＰＤＢＡ平板上可抑制苹果轮纹病、炭疽病、霉心病病菌的菌丝生长，其无菌滤液对苹果轮纹病、炭疽病、霉心病的菌丝生长有抑制作用．在苹果生育前期，适时喷施Ｂ０１７于苹果表面，后期褐斑病发病率下降２０．９１％～２４．７３％，病情指数下降２１．６３％～３９．５６％；苹果轮纹病、炭疽病、霉心病的发病率分别下降２５．１５％～４３．０２％，３０．４９％～６８．４９％，２７．２７％～３６．８８％．苹果的一年生脱毒苗喷施Ｂ０１７后，能促使苗高增加，离嫁接口５ｃｍ处的径粗增大．
Laboratory tests showed that: the bacteria B017 can inhibit the brown spot of spores germination; PDBA plate can inhibit apple ring disease, anthracnose, mycosis fungal pathogen mycelium growth, the sterile filtrate on apple ring disease, anthracnose , Moldy mycelium growth inhibition. In the early stage of apple fertility, B017 was sprayed on the surface of apple in time, the incidence of late brown spot decreased 20.91% ~ 24.73% and the disease index decreased by 21.63% ~ 39.56%. Apple ring disease, anthracnose , The incidence of mold heart disease decreased by 25.15% ~ 43.02%, 30.49% ~ 68.49%, 27.27% ~ 36.88% respectively. Apple annual detoxification vaccine spraying B017, can promote increased seedling height, diameter of 5cm away from the graft interface at the coarse increase.
