Azoxystrobin and chlorothalonil, the main pesticide dosage form: 56% suspension agent, Ami colorful developed by Swiss Syngenta, containing chlorothalonil + azoxystrobin 500 + 60 g / liter (active ingredient).
Mechanism of action: Prevent spore germination, azoxystrobin is an energy inhibitor, inhibit spore germination and mycelial infection by inhibiting the respiratory process of pathogenic bacteria; chlorothalonil is an inhibitor of enzyme activity, by deactivating phosphate in fungal cells Hydrogenase activity leads to fungal death. Ami colorful has both contact and systemic activity, can kill the infected bacteria, and is applied to the diseased plants with cucumber brown spot and downy mildew.
Product features: It has an ultra-wide sterilization spectrum, which regulates plant growth, improves yield and improves quality. Because of high-tech additives and advanced synthetic technology, the bactericidal activity is stronger than the single drug, and the bactericidal spectrum is more extensive. It has good control effects on fungal oomycetes, basidiomycetes, deuteromycetes, ascomycetes, and zygomycetes. Delays the emergence of drug resistance in a single drug crop.
Usage: According to the pesticide network , Ami colorful is defined as a broad-spectrum bactericidal protective agent. It can be used in the crop seedling stage and in the late growth stage or when the disease is mild. It can effectively prevent downy mildew and leaf blight of melon. , powdery mildew, anthracnose, brown spot, etc., can prevent early blight, late blight, leaf mold, white powder, gray mold disease of solanaceous vegetables, and can control almost all fungal diseases of various crops, 1000 ~ 1500 times spray, using this dose to root, can prevent dead trees caused by fungi.
1 Prevention and treatment of tomato early blight, 75 ~ 120 ml / mu.
2 control cucumber brown spot disease, downy mildew, spray the diseased plant with 56% Ami colorful suspension agent 600 ~ 800 times solution, have good therapeutic effect in the early, middle and late stages of the disease, especially in cucumber brown spot, downy mildew The effect is obvious in the early and middle stages of the disease, the treatment effect is good, the effect period is long, the dosage is reduced, the leaves are bright and soft after application, and the photosynthesis is enhanced, thereby increasing the yield and improving the quality of the cucumber.
3 control pepper anthracnose, 80 ~ 120 ml / mu.
4 control watermelon blight, 75 ~ 120 ml / mu.
5 Prevention and control of Phytophthora capsici Phytophthora, 500-1000 times liquid leaf even spray, application interval 7 to 10 days. On the lychee, continuous rainy days are encountered in the period before flowering, young fruiting, fruit expansion and coloring. It is necessary to focus on protection, spray the water uniformly and uniformly, and rotate with other agents.
Precautions:
1 The sooner the drug is used, the better it will be. If it can be used before the disease occurs, it will have a good protective effect on the plant and enhance immunity. Shake well before use before taking the medicine.
2 In the case of continuous rainfall, or conditions of high disease, or in the rapid growth period of the crop, it is recommended to use a higher dose, or to reduce the application interval appropriately.
3 Azoxystrobin in Ami colorful is sensitive to apple trees. It is recommended to avoid using this product near the apple orchard; chlorothalonil is sensitive to certain varieties of grapes, so Ami Colorful is not recommended to apply near the vineyard.
4 In order to reduce the occurrence and development of resistance, it is recommended to use methoxy acrylate-based fungicides no more than 3 times during the whole crop growth period, and rotate with other drugs with different mechanisms of action.
5 This product has a wide spectrum of sterilization, and the Chinese pesticide network is recommended to be used alone. In order to avoid phytotoxicity, it should not be mixed with any emulsifiable pesticide products or surfactants.
