Mancozeb is not easy to produce resistance, the control effect is obviously better than other similar fungicides, and it has the effect of increasing yield and protecting crops. Mancozeb is a multi-site fungicide, which can effectively inhibit the oxidation of pyruvate in the bacteria, and elements such as manganese and zinc have obvious effects on crop growth and yield increase. Mancozeb is often mixed with systemic fungicides to achieve the purpose of improving the control effect and delaying pathogen resistance.
Mancozeb can be used alone or in combination with a variety of systemic fungicides, all of which can achieve ideal control effects and are not easy to produce resistance. Mancozeb can meet the needs of farmers and the market in many ways, reduce the cost of medication, and solve the problem of pathogen resistance. Broad bean red spot disease: Through field trials, the effects of different treatments such as mancozeb seed dressing and spraying on stems and leaves at five-leaf, eight-leaf, and nine-leaf phases on the spatial distribution of corn brown spot disease and the control effect were studied. The results show that the spray treatment of mancozeb at the 5-9 leaf stage of maize can effectively inhibit the expansion of corn brown spot disease from the lower leaves to the upper leaves, especially the 8-leaf stage spray treatment can control the diseased leaves at the sixth expanded leaf Within, the control effect reached 88.9%, and the yield increase rate reached 31.5%. The eight-leaf stage is the best medication period for the prevention and treatment of corn brown spot.
This product is a broad-spectrum foliar protection fungicide. It is widely used in fruit trees, vegetables and field crops. It can prevent and control a variety of important leaf fungal diseases, such as wheat rust, corn leaf spot, potato phytophthora, and fruit trees. Scab, anthracnose, etc. The dosage is 1.4-1.9kg (active ingredient)/hm2. Because of its wide application and good efficacy, it has become an important species in non-systemic protective fungicides.
