It has been found that azoxystrobin is toxic to tomatoes in protected fields, so it should be used with caution within 2 weeks after tomato seedlings are transplanted. It was found that vegetable white spot disease had developed resistance to azoxystrobin, and the effect was obviously reduced after continuous application for more than 2 times.
The original drug and compound of azoxystrobin have passed the patent period. From March 2065438 to March 2003, a large number of domestic manufacturers began to produce and promote single-dose and compound products, which had a great impact on other types of fungicides.
Main dosage forms and contents of China:
25% suspending agent, 50% water dispersible granule, 32.5% azoxystrobin difenoconazole suspending agent, 20%-32% azoxystrobin propiconazole suspending agent and 20%-50% azoxystrobin suspending agent; 10% to 50% azoxystrobin dimethomorph SC/WG, etc. (excluding seed treatment).
Functional characteristics
1. Broad bactericidal spectrum: One medicine can cure many diseases, reduce dosage and production cost.
2, increase disease resistance: less illness, vigorous growth, early birth and early listing.
3. Improve stress resistance: high yield in bad weather.
4. Delay aging: prolong the harvest period, increase the total output and increase the total income.
5. Long duration: specific effect period 15 days, which can reduce drug use times and pesticide residues in vegetables.
6. High efficiency and safety: strong internal absorption and infiltration effect is obvious, natural and low toxicity, safe and pollution-free.
Use of azoxystrobin
The best application time of azoxystrobin is before flowering, after flowering and young fruit stage. The application method is in the early stage of downy mildew, early blight, carbuncle and leaf spot. Generally, 25% azoxystrobin SC is sprayed on the stems and leaves once every 10 day, and crops can use it up to 3 times per season. Please refer to the specific instructions.
Azoxystrobin is a new type of high-efficiency broad-spectrum systemic fungicide, which can be used for stem and leaf spraying, seed treatment and soil treatment. Azoxystrobin has good activity against almost all pathogenic bacteria in the fungal world, and its bactericidal spectrum is wide. Can be used for treating various diseases on crops such as grains, vegetables, fruit trees, peanuts, potatoes, coffee, lawns and the like. Such as white spot disease, rust disease, glume blight, nettle spot disease, downy mildew, rice warm disease, etc. The specific dosage can be adjusted according to different crops and diseases. Generally, 2.5-26 grams of active ingredients can be applied per mu. ..
In addition, azoxystrobin can also increase the disease resistance of plants, with a longer specific effect period, reduce the frequency and cost of drug use, delay crop senescence, prolong harvest period and increase total output. However, it should be noted that azoxystrobin cannot be mixed with emulsifiable concentrate pesticides or silicone synergists.
