Daisenlian product features:
1 Wide spectrum of bactericidal, it is a multi-effect complexing contact fungicide , which can effectively control a variety of diseases; seed treatment can prevent seed and root diseases such as squatting disease and root rot.
2 It has a nutritive effect and contains 18% zinc, which is conducive to the synthesis of chlorophyll, increases photosynthesis, can improve the color of fruits and vegetables, makes fruits and vegetables brighter, and leaves greener.
3 Improve crop yield and improve quality; compared with various types of mancozeb, the control effect on melon downy mildew is obvious, and the killing effect on beneficial predatory mites can be reduced.
4 It is not easy to produce resistance. The drug is a multi-enzyme inhibitor, which interferes with the multiple enzyme sites of the bacteria cells, and thus is not easy to produce resistance.
5 It has good safety and wide application range. It is suitable for all periods of most crops, and many crops can also be used.
6 The dosage form is advanced. The dry suspension dosage form has finer particles in the water, higher suspension rate and more stable solution, thus showing better safety and effect and higher utilization rate.
7 It has a preventive effect on the main diseases of crops such as downy mildew, early blight, late blight, scab, anthracnose, rust and leaf spot.
8 Daisenlian is often compounded with bactericidal agents such as pyraclostrobin and cymoxanil.
Daisen zinc product features:
Dyson zinc is a protective organic sulfur fungicide. Dyson zinc is safe for plants, chemically active, and easily oxidized to isothiocyanate in water. It has a strong inhibitory effect on the enzyme containing -SH group in the pathogen, and can directly kill the spores and inhibit the spore germination. It prevents the invading of the plant, but it has less killing effect on the pathogenic mycelium that invades the plant.
Control objects: cabbage, cucumber downy mildew, tomato anthracnose, potato late blight, grape white rot, black spot, apple, pear scab and so on.
Mancozeb product features:
Mancozeb is a highly effective, low toxicity, broad spectrum protective fungicide. The mechanism of action is to bind to the sulfhydryl group in the dithiooctanoate dehydrogenase involved in the pyruvate oxidation process, thereby inhibiting the oxidation of pyruvate in the bacteria. Can be used in combination with systemic fungicides to delay the development of drug resistance. The so-called protection is to provide Zn element for plants. In addition to solving the symptoms of zinc deficiency, the plant is enhanced in its ability to resist disease, thereby playing a relatively bactericidal effect.
Control objects: pear black scab, citrus scab, ulcer disease, apple spotted leaf disease, grape downy mildew, litchi downy mildew, Phytophthora, green pepper blight, cucumber, melon, watermelon downy mildew, tomato blight, cotton Rotten bell disease, wheat rust, powdery mildew, corn spot, streak, tobacco black shank, yam anthracnose, brown rot, root neck rot, spotted leaf disease.
The difference between Daisenlian, Daisen Zinc and Mancozeb:
The difference is that the smell is different.
Mancozeb - the smell of rotten eggs
Desen zinc - sulfur smell
Daisenlian - fishy flavor
Distinguish the structure of the two molecules is different
Figure 1 Dyson zinc structure
Figure 2 Daisenlian structure
Figure 3 Mancozeb structure
Distinguish three zinc levels differently
Mancozeb has a zinc content of 2.55%, a zinc content of 8%, and a zinc content of 18%.
The difference between the four effects is different
The manganese ion in mancozeb was proposed and evolved into daisen zinc. However, it is proved that the sensitized zinc has no bactericidal spectrum, and the protective ability is general and has no killing effect on the fungus. The amount of zinc is a little higher than that of mancozeb, and the market is preparing to eliminate the variety.
The zinc ion and manganese ion in the common manganese zinc are fused together, and it is not a single manganese ion, and there is almost no phytotoxicity. This is the complex state mancozeb. The advantage of complex state mancozebide is that it is safer and more efficient than ordinary manganese zinc. Ordinary mancozeb (non-complexed) easily decomposes manganese ions, which can cause phytotoxicity.
Daisenlian has higher zinc content, better protection effect, and obvious brightening effect of foliage greening fruit surface. Improve crop yield and improve quality; compared with various types of mancozeb, the control effect on melon downy mildew is obvious, and the killing effect on beneficial predatory mites can be reduced.
The difference between the five holding periods is different.
Daisenlian has good quick-acting effect, long-lasting effect, safe use, and no phytotoxicity even during flowering.
Dyson zinc is sterilized and supplemented with zinc. Both bactericidal and zinc supplementation are quick-acting, and the efficacy is short, usually 5 to 7 days.
Manganese in mancozeb can control the release rate of zinc, making the effect last longer. The general efficacy lasts for 10 to 15 days, which is longer than that of zinc.
