With drugs to prevent and control rice pests
The transplanting of rice with medicine is a prevention and treatment of insect pests, the migration of the gateway, and cost-effective macro-control measures, which can reduce the pressure of pest control in the middle and late stages of rice and fight for active prevention and control. In order to effectively prevent rice leaf mites, control rice water weevil, and treat rice generation mites, the township (township) agricultural service centers must intensify the promotion and promotion of rice seedlings with drugs for transplanting and ensure the safety of rice production.
In our district, we discovered rice water weevil in 2012. The main areas that we have occurred are Minjiang, Fulong, Lingjia, Yong'an and other towns (the area of ​​rice water weevil occurred in 2016 was 5,800 mu). This year, 5you39 high quality rice was planted in a concentrated area2 More than 10,000 yuan, in order to effectively prevent and control rice rice water weevil, reduce the spreading spread of pests, treat a generation of aphids, prevent rice leaf blast, require the full implementation of rice with medicine transplanting, take the combined control of defense and farmers self-defense.
Control methods: In the area of ​​rice water weevil, paddy field (including dry nursery) was sprayed once in full coverage 2-3 days after the film was uncovered, and mu (200 g/l) of chlorantraniliprole (Kang wide) suspension was used. 10 ml, or 10% tetrachlorfencamide suspension (trade name 9080) 10 g, or 48% chlorpyrifos (fish farm banned) EC 60 ml watered 45 kg conventional spray, rice 2-3 days before transplanting, mu With 75% tricyclazole wettable powder 30g + (200g/L) Chlorantraniliprole (Kang) suspension 10ml, or 75% tricyclazole wettable powder 30g + 10% Tetrachlortetracide suspension ( Product name 9080) 10g, watered with 45kg conventional spray, evenly sprayed to the seedlings drip, can effectively prevent leafhoppers, control rice water weevil adults, and at the same time treat the rice generation of aphids.
Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
