1. Cucumber disease prevention and testing sites were hybrid cucumbers at the third generation of Shichengliang Greenhouse Greening, Tangsan Village, Hushitai Town, Xinchengzi District, Shenyang City. The test agent is 65% Sterling Aqueous, 40% Bacteriostasis wettable powder, plant gene activator. The control was 75% chlorothalonil wettable powder and 10 million units of agricultural streptomycin sulfate. On March 20, 50% of plants in the greenhouse were found to have a mixture of downy mildew and angular spot disease. Use 65% Sterling 25 ml plus bacterial fasting 20 grams plus gene activator 10 grams of 15 kilograms of water to spray the entire plant positive and negative, spraying 60 kilograms per acre. The control was sprayed with water in the same manner as described in 25 parts of chlorothalonil 25g plus 7.5g of streptomycin and thiophanate-methyl 20g. Spray once every 7 days, and spray 3 times. After spraying, 70% of the plants that sprayed the biological pesticides were controlled, while only 40% of the plants in the control area were controlled. After 10 days of investigation, the cure rate of biopesticides sprayed was 100%, and the quality of cucumbers became better, while the control spraying plants only controlled about 70%. The yield of cucumber sprayed with biological pesticides is about 30% higher than that of the control drug, and it is welcomed by consumers after being listed. 2. The prevention and treatment of eggplant disease was conducted in Qiujingtao Greenhouse Xi'an Lvqiu, Dagu Village, Hushitai Town, Xinchengzi District. The test agent was 65% Streoxin, Kecongang and gene activator; the control was PT fungicide and multi-bacterial. spirit. On June 2nd, 30% of the eggplant plants had burping and yellow-green interphase lesions. After mixing 15 grams of gene activator and 15 grams of stimulant 20 ml plus Stirling, 15 kilograms of water was irrigated. 250 grams of liquid medicine. The PT fungicide 20 g plus carbendazim 20 g was mixed with the PT fungicide and water was poured in the same manner. After spraying, 80% of the eggplants fed with biopharmaceuticals after 5 days of irrigation were returned to normal, whereas only 50% of the diseased plants recovered in the control area; after 7 days, 100% of the eggplants filled with biopharmaceuticals had returned to normal, whereas the control area had only 70% returned to normal and there were dead strains. During the collection period, the eggplants that were fed with biopharmaceuticals were investigated with large oil output, and the yield was about 25% higher than that in the control area. 3. Summary Use of Sterling, Bacteria and other biological agents, can kill pathogens to make crops grow well; spray gene activator can make crops enhance immunity, significantly improve the resistance to disease resistance, so as to obtain high quality and yield, produce additional High value of pollution-free green food.
