[market forms of]:70- and 80- mancozeb Wettable powder 80- grams, spray, The students M-45 , mancozeb wettable powder.
: physicochemical properties for maneb and zineb. Complex compound 20-, manganese, zinc containing 2.55-. Original gray powder, melting point 192 ℃ ~ 204 ℃ (decomposition). Solubility: insoluble in water and most organic solvents, soluble in strong chelating agent in solution. The generally stable in dry environment, heating, and humid environment in slow decomposition, acid alkali decomposition, can cause burning.
The most fierce zinc Mainly used for the control of vegetable Downy mildew , anthracnose, Cercospora leaf spot Etc.. At present is to prevent and cure Tomatoes Early blight and Potato Late blight ideal agents, control effect were 80- and 90-. Yes Carbendazim Produce Resistance The disease, to most fierce zinc can receive the good effect of prevention and cure. For the general Leaf Spray, spray 1 times every 10-15 days.
(1) control of tomato, Eggplant , potato Epidemic disease , Anthracnose , Leaf spot , WP 400-600 times liquid with early onset 80-. Spray The way, 3-5 times.
(2) control of vegetable seedling Damping off , Damping off disease 80-, use the Wettable powder , according to Seed The weight of the 0.10.5- dressing.
(3) control of downy mildew of cucurbits, Anthracnose , brown spot, with 400-500 times liquid spray, 3-5 times you.
(4) control Chinese Cabbage , cabbage Downy mildew , celery Spot disease 500, with a 600 times liquid spray, 3-5 times you.
(5) control Bean anthracnose , leaf spot, 400-700 times liquid spray, even 2-3 times.
(1) during storage, care should be taken to prevent high temperature, and to keep dry, in order to avoid high temperature, humid conditions makes the chemical decomposition, reduce the effect.
(2) in order to improve the control effect, and various Pesticides Chemical fertilizer, mixed use, but not with alkaline pesticides, fertilizers and solution containing copper mix.
(3) chemical stimulation of the skin, mucous membrane, pay attention to protect the use.
(4) not with alkaline or copper containing mixed medicament. Toxic to fish, do not contaminate water.
Mancozeb is an excellent protection Bactericide , low toxicity pesticides. Because of its sterilization range, not easy to produce resistance, prevention is better than other similar bactericidal agent dosage, so in the world has been the large tonnage products. At present, the majority of domestic compound bactericide with mancozeb and compounding, manganese, zinc trace element is promoting strong, obvious yield increasing effect on crop, through years of field application, on the prevention and control of Pear scab , Alternaria leaf spot of apple Phytophthora blight, downy mildew, vegetables, field crops Rust Results are obvious, without any other fungicides can effectively control the disease, stable quality, reliable.
The main control object: pear scab, Citrus Scab disease, ulcer disease, alternaria leaf spot of apple, Grape Downy Mildew , litchi downy mildew, Phytophthora blight, pepper phytophthora blight, Cucumber Watermelon, muskmelon, downy mildew, Tomato Disease, cotton boll rot, Wheat rust , powdery mildew, Corn Big spot, leaf blight, Phytophthora nicotianae, Yam anthracnose , brown rot, root rot, leaf spot disease.
(1) control Jujube tree Apple, pear, etc. Fruit tree Leaf spot, rust, Scab , downy mildew and other diseases, begin spraying 800 times 80- mancozeb wettable powder on early onset (Aino Ai Sheng +1000 times)" Tianda 2116 "(fruit special type), 1 times per day 10-15, continuous spray 2-3 times. Attention and Bordeaux mixture Alternate use of.
(2) control of vegetable diseases, downy mildew, anthracnose, use 600-800 times 80- mancozeb wettable powder (Aino Ai Sheng) +600 (2116 times the Tianda melon eggplant fruit), once every 7-14 days, alternating between other pesticide spraying.
(3) control of downy mildew, powdery mildew, crop leaf spot disease, Root rot And so on, wettable powder 700-1000 times 80- mancozeb in early onset (Aino Ai Sheng) +600 2116 times the Tianda Zhuang Miao Ling, once every 7-14 days, alternating between other pesticide spraying.
Mancozeb preparation process is the use of organic solvents and mancozeb wet product mixture distillation dehydration, especially in the solvent as carrier after injection heating or after film evaporator heating distillation dehydration, can make the dehydration process and wet grinding, modulation, packaging processes of continuous operation, the maneb zinc complexation with * in organic solvents and dehydration crystallization process at the same time, reduce product decomposition, reduces the harmful impurities and dust pollution, avoiding the occurrence of fire accidents product drying process. The invention of the solvent dehydration speed fast, production safety and high efficiency, and simplifies the production process.
