The weather in this month is often rainy and hot, and the weather is conducive to the occurrence of diseases and insect pests, which is not conducive to proper drug control. The prevention and control of the following pests and diseases should be mainly done. 1. Insect pests: Continue to do a good job of prevention and control of aphids (including flowers, seedlings), thrips, diamondback moth, cabbage caterpillars, Liriomyza sativae, aphids, flea beetles and underground pests. Pay attention to the prevention and treatment of corn mash on vegetable corn and bean pods during the flowering period of cowpea. Corn borer can be used for drug control in young instar larvae, and the agent can be used with 5% Ruijinte SC1500-2000 times. Bean curd control principles: Treating flowers and leaving no one, combining plant flowers with floor-to-ceiling flowers, should be applied when the bean blossoms are open at 6-9 in the morning. At this time, the liquid is easy to contact with the worms and spray on the flowers, buds and landing flowers. on. From buds, buds and flowers are sprayed every 10 days. Pharmacists can choose 5% rigorous SC1500-2000 times, 1% avermectin EC (ecencide) 3,000 times, 48% Lost EC 800-1000 times and so on. Second, the disease: In addition to continuing to do a good grasp of downy mildew, disease, powdery mildew, anthrax, virus disease and bacterial angular spot disease prevention and control (control methods can refer to the previous "plant protection soil fertilizer garden"), should also focus on Good prevention of wilt, rust, root rot, corn, and leaf spot diseases. Fusarium wilt: It can be killed during the whole growth period, but it suffers the most during the period of squashing. Soil disinfection before sowing: 50% carbendazim WP 500 times, until the liquid infiltration after sowing, and then covered with soil. In the early stage of disease, it is possible to use thiophanate-methyl 700-fold, chlorothalonil 800-fold, "agricultural 120" 300-fold, carbendazim 500-fold, medicated tannin 500-800 times, and 98% mycophenolate WP 3000-fold. 40% root rot Ning WP 500 times Irrigation, 250 ml/plant. 5-7 days once, continuous 2-3 times. Rust: In the early stage of disease, 15% triadimefon WP1000-1500 times, 40% Fuxing EC9000 times, 30% Goodrich SC5000 times, 1 time every 15 days, and spray 1-2 times. Root rot: The severity of the disease is related to the sowing date and sowing depth. Sowing too early or too deep is caused by low soil temperature and slow emergence of seedlings. In addition, the incidence of clay, poor drainage, heavy ploughing, and extensive farming is heavy. In the early stage of disease, 70% of dexamethasone WP1000 times, 72.2% of fluoxamers WC750 times, 72.2% of prophymidone WC750 times, 5% of Jinggangmycin WC1500 sprays or thirams or chlorothalonil and other chlorothalonil agents can be used for prevention and treatment. Every 7-10 days, depending on the condition of the disease and prevent 2-3 times. Maize big and small spot disease: comprehensive prevention and treatment measures should be taken to use disease-resistant seed varieties, strengthen cultivation management, reduce bacteria sources, and combine with chemical control. After corn is harvested, it should be ploughed in time to remove the diseased leaves at the bottom and be cleared out of the field to reduce the amount of re-inoculated bacteria in the field to prevent the disease from spreading to the middle and upper leaves, and to improve the field microclimate and delay the occurrence of diseases. With popularity. In addition, the implementation of large-scale rotation of 1-2 years can also effectively reduce the source of bacteria. The use of appropriate early sowing, reasonable interplanting, reasonable close planting, scientific fertilization, ditch drainage, weeding and other cultivation management measures can reduce the incidence of disease. Drug control can be used as an important measure to eliminate the disease center in the field, reduce the source of bacteria, and reduce the incidence. Before and after corn picking, the spraying began before the disease spread, spraying once every 7-10 days for 2-3 consecutive times. The agent can be used 50% carbendazim WP500 times or 90% mancozeb WP500 times or 75% Dakkonin (chlorothalonil) WP500 times.
Plasma Sterilizer
Plasma sterilizer is to sterilize by hydrogen peroxide low-temperature plasma.Through sterilization,a certain method is used to inactivate various microorganisms on medical instruments and surgical instruments,thereby achieving the purpose of sterilization.
1,Medical plasma sterilizer: sterilization temperature of 50°C± 5°C,low temperature and no humidity,no damage to the sterilization articles and equipment,can extend the life of precision instruments.
2.Medical plasma sterilizer green and environmental protection:hydrogen peroxide solution is used as sterilizing agent,no toxic substance remains,no drainage or exhaust is required,no damage to the operator's body,and special filters for high efficiency can be applied to the air intake and exhaust ports.Absorption of H2O2 from the process of vacuum rejection will result in zero pollution to the environment.
3.Medical plasma sterilizer sterilization stability:The sterilization chamber is made of aluminum or stainless steel,which has advantages of anti-corrosion and thermal conductivity,which makes the temperature of the sterilization chamber more balanced and effective, and ensures that H2O2 maintains 100% of the gas throughout the process.The hydrogen peroxide low temperature storage system ensures that the hydrogen peroxide concentration is stable and effective and does not volatilize.
4.High sterilizing efficiency:The design of a rectangular sterilization chamber makes it possible to load more instruments at a time and make the use of the sterilization chamber more convenient.
