How to use Paecilomyces pubescens on strawberries?

Control scope of Pythium Shaoxiong on strawberry: strawberry powdery mildew, strawberry gray mold, strawberry snake eye disease and other fungal diseases: strawberry powdery mildew: pathogen Alternaria maculata strawberry gray mold: pathogen Botrytis cinerea human strawberry snake eye disease: also known as strawberry white spot disease, strawberry leaf spot disease. Pathogenic fungus strawberry soft rot pathogen: pathogenic fungus Rhizopus strawberry Phytophthora: pathogenic fungus Phytophthora strawberry brown spot pathogen: pathogenic fungus Phomophilum murrayum. Usage: 1 Root irrigation: Three days after strawberry transplanting, root irrigation with "Pythium Leviathan" 10000 times dilution can effectively kill soil-borne pathogenic fungi, promote strawberry root development and cultivate strong seedlings. 2. Spraying: About 2 weeks after strawberry transplanting, the strawberry leaves were sprayed with the diluted solution of Penicillium plumbum with the concentration of 7500- 10000 times, and it was used continuously for 2-3 times with the interval of 15 times, which could improve the stress resistance of strawberries and effectively reduce the invasion of diseases. 3. After the strawberry bears fruit, the leaves and fruits are sprayed with Pythium olivaceum diluted 7500 times, focusing on the fruits, which can effectively prevent and control fungal diseases such as downy mildew, anthracnose and powdery mildew of strawberry. It is recommended to spray once every 0/5-20 days. The application effect is 1. It can effectively control seedling diseases, promote seedling root growth and improve seedling survival rate. 2. It can effectively kill harmful fungi invading strawberries, improve plant immunity and effectively reduce replantation hazards. 3. Promote the growth of strawberry root system, make plants grow fast, grow vigorously, resist high temperature, and promote photosynthesis and nutrient absorption. 4. Improve the fruit setting rate, which can generally be increased by more than 50%, with less deformed fruits, large fruits and neat shapes. 5. Extend the harvest period. Generally, the fruit-bearing period can be extended by 20-25 days, and the yield will generally increase by 30%-50% to increase farmers' income. 6. Replace the use of chemical pesticides. Because this product is a pure natural biological preparation, there is no residue problem and it is safe to the environment. Precautions 1. This product is an active fungal spore and cannot be mixed with chemical fungicides. After spraying chemical fungicides, it is forbidden to use this product during the efficacy period; Containers using chemical fungicides should be thoroughly cleaned before using this product. 2. In sunny days without dew and wind, spray before 9 am and after 4 pm; When spraying, the liquid should make the whole plant wet, including the front and back sides of leaves, stems, flowers and fruits, and penetrate down to the roots. 3. This product can be mixed with other fertilizers and pesticides. 4. This product should be stored in a dry, cool, ventilated, rain-proof place with a shelf life of 2 years. Experimental report on control of strawberry anthracnose by Pythium oligosaprophyticum Experimental unit: donggang city Strawberry Research Institute, Liaoning Province: Diao Yufeng and Du Yubin. As the main strawberry producing area in China, donggang city has serious anthrax in daily production, which is caused by fungi. It can be divided into two symptoms: local lesion and whole plant wilting. Local lesions are most likely to occur on stolons. The lesions on stems and leaves are reddish brown at first, then black, slightly depressed and ulcerated, and finally die above the lesions. Wilt-type diseased plants, at first brown-red spots appear on the edge of diseased leaves, and then turn brown or black. When the illness is mild, the leaves wither during the day and recover at night. When the illness is serious, they die a few days later. Anthracnose affects the growth of strawberry, reduces the quality of strawberry fruit, seriously leads to the large-scale death of strawberry plants and affects the income of fruit farmers. In order to control anthracnose in strawberry solar greenhouse production, we tested a variety of chemicals in strawberry solar greenhouse production season from 2008 to 2009, and found that Penicillium had good control effect. 1. Materials and Methods 1. 1 The test reagent "pythium oligoandrosum" is produced by Beijing Bairui Biotechnology Co., Ltd., and its main component is pythium oligoandrosum. Clove apigenin bactericide was produced by Dalian wesen Chemical Co., Ltd., and agricultural streptomycin (24% soluble powder) was produced by Shanghai Nongle Biological Products Co., Ltd., and the experimental place was in the sunlight greenhouse of the original seed demonstration field of donggang city Strawberry Research Institute. The greenhouse covers an area of 424m2, with brown soil and medium fertility. The tested variety is Hongyan (No.99), with two rows of big ridges, the ridge spacing is 0.85m, the north-south direction, the plant spacing is 15cm×20cm, and the ridge length is 7m. It was planted on September 3rd, 2008, and the film was buckled on June 6th, 5438+00. 1.2 experimental design experiment * * * was designed with four treatments, namely, pythium shaoxiong 7500 times solution, syringin 600 times solution, agricultural streptomycin 600 times solution and control (clear water). Every three ridges are a plot, arranged randomly and without duplication. The experiment was carried out on September 28th, 2008 (after the slow-release seedlings were planted), and the leaves were sprayed once every15th day, with a total of 6 times. After each application, 100 plants were randomly investigated in each plot to investigate the incidence and control effect of anthracnose. 2. Results and Analysis It can be seen from the table 1 that the control effect of pythium parvum is more obvious than that of syringol and agricultural streptomycin, and the control rate is 4% higher than that of syringol and agricultural streptomycin. As can be seen from Table 2, the biological and economic characteristics of the three drugs have been improved in different degrees compared with the control, but the differences among the three drugs are not obvious. 3. Summary Through this experiment, it can be seen that Pythium shaoxiong and eugenol have better control effect on strawberry anthracnose in solar greenhouse, and the control effect of Pythium shaoxiong is more prominent. It is suggested to continue to apply it in the next production season and observe the effect. Table 1. The control effect of different chemicals on strawberry anthracnose: the number of diseased plants (per kloc-0/00) before treatment and the number of diseased plants (per kloc-0/00) after six times of application, the control rate is 7,500 times of levofloxacin solution and 600 times of syringol solution, 4,0/0.90% of agricultural streptomycin. % clear water (CK) 417-Table 2.
