Abstract
The invention provides a plant disease combined fungicide. Especially the pesticide composition with prochloraz manganese salt and propineb as active ingredients, prochloraz manganese salt is prochloraz-manganese chloride, which is a broad-spectrum fungicide of imidazoles, which acts by inhibiting the biosynthesis of sterols. It has a good control effect on a variety of crop diseases caused by ascomycetes and semi-known fungi. Compared with prochloraz, the drug has high safety and is not easy to cause phytotoxicity. It is suitable for mushroom brown rot and brown spot. Mango anthracnose, citrus penicillium, green mold, anthracnose, pedicle rot, banana anthracnose, cucumber anthracnose, etc. Prosenb is a quick-acting, long-lasting, broad-spectrum protective fungicide, which is effective against It has a good protective effect against downy mildew of vegetables, tobacco, hops and other crops, as well as early and late blight of tomatoes and potatoes. It can control cabbage downy mildew, cucumber downy mildew, tomato morning and evening blight, mango anthracnose, and also has a certain inhibitory effect on powdery mildew, rust and diseases caused by Botrytis. It is safe for crops at the recommended dosage.
Description
technical field [0001] The invention relates to a combined fungicide for plant diseases, in particular to a pesticide composition with prochloraz manganese salt and propazine as active ingredients, and belongs to the field of pesticide chemical industry. Background technique [0002] In the actual process of agricultural production, a plant disease is often caused by several pathogens, and it is impossible to achieve the best control effect with only one chemical, and it is easy to produce resistance problems. One of the most cost-effective methods to overcome is to compound the active ingredients of different varieties. According to the actual test effect, it is judged whether the combined fungicide is synergistic, additive, or antagonistic. The compounded and synergistic formula significantly improves the comprehensive control effect and reduces the amount of pesticides used, thereby greatly delaying the emergence of disease resistance and achieving the purpose of one ...
