For different diseases of rice, it is necessary to use medicine scientifically and to use drugs. China Pesticide Network Xiaobian introduces you in detail:
Rice blast: 100 grams of 20% tricyclazole wettable powder per acre, or 40% rice glutinous rice (Fuji 1) 60-70 ml, or 40% virulence suspension 200 g, 30 kg of water spray. Keqisan and carbendazim can also be used to prevent rice blast, but the control effect is not as good as the above agents. Sheath blight: 5% Jinggangmycin water 150 ml per mu or 10% Jinggangmycin powder 50 g, 50 kg spray with water. For heavy illness, if you need to fight 2 times, the interval is 7-10 days.
Bacterial blight, bacterial stripe disease: use 25% leaf sulphate (also known as Chuanhua 018) or yeqing double wettable powder, 100 grams per acre, add 50 kilograms of water spray. Hybrid rice ear disease: such as rice leaf blight, rice smut, cloud disease, sheath rot, granule black powder and leaf black swollen disease, etc., 25% powder rust WP can be used 50 grams per acre, or 40 % He Ku Ling WP can be 40-50 grams per acre, plus 50 kilograms of water spray control.
Rice planthopper: use 25% of chlorpyrifos WP for 30 grams per mu, or use 10% insecticide imidacloprid WP for 15-20 grams per mu, or use 10% leaf è‰ WP for 200-mu per acre 250 grams, or 10% fast-acting WP can be 150-200 grams per acre, spray 30-40 kilograms of water. The field should have a shallow water layer of 3-7 cm when applied.
Locust: use 18% insecticidal double water agent 200-250 ml per mu, or 90% insecticidal single 40-50 grams per acre, or 50% Bataan wettable powder 100 grams per acre, or 18% insecticidal double water 150-200 ml per mu plus 100 ml of Bt emulsion per acre, 30-40 kg of water spray control. Rice leaf roller: use 18% insecticidal double water agent 250ml per mu, or 50% Bataan wet powder 100g per acre, or 18% insecticidal double water agent 150-200ml per acre Bt emulsion per acre 100 ml, spray control of 30-40 kg of water. It is forbidden to use pyrethroids and their mixed pesticides in rice fields. It is strictly forbidden to use high-toxic pesticides such as methamidophos in the later stage of rice. In the early stage of rice, the use of organophosphorus pesticides such as triazophos to control aphids will lead to the outbreak of rice planthoppers in late rice. Therefore, the use of organophosphorus agents should be used cautiously in the early stage.
Metal Chelating Affinity Chromatography is widely used in purification of His-tagged recombinant protein. The immobilized metal affinity chromatography resin provides exceptional binding capacity and performance for recombinant His-tagged Protein Purification. UniNi affinity resin consisting of chelating resins charged with nickel ions is specifically designed to capture and purify histidine containing proteins.
UniNi affinity chromatography resin is based on monodisperse rigid porous polymer beads coating with a highly hydrophilic intermediate layer, following by attached with an optimized density of chelating ligands. The resulting metal affinity resins have low non-specific bindings and high capacity for histidine containing proteins.
