Can azoxystrobin and organosilicon be mixed? See clearly. Don't make mistakes again!


Azoxystrobin has a wide range of bactericidal spectrum. It is soluble in methanol, acetonitrile and other solvents except for emulsifiable oil, and has good activity for almost all fungal pathogens. However, although there are many advantages, it is worth mentioning that the use of azoxystrobin should pay attention to the prevention of drug harm.


Azoxystrobin, as a highly effective and broad-spectrum Fungicide of Methoxyacrylate, can not only treat multiple diseases with one drug, but also increase the disease resistance and stress resistance of plants, especially its long specific period, reduce the times and cost of drug application, delay the aging of crops, lengthen the harvest period and increase the total yield. It is understood that azoxystrobin has a good activity on almost all fungal pathogens, so up to now, domestic and foreign enterprises take azoxystrobin as the main effective component, aiming at the diseases such as powdery mildew, rust, glume blight, reticulosis, downy mildew and rice blast caused by mycosis such as Ascomycetes, basidiomycetes, flagelliformes and seminiflora, which are caused by China's agriculture The pesticide Inspection Institute registered 348 pesticide formulations, including leaf spray, seed and soil treatment. It can be used for crops such as cereals, rice, peanuts, grapes, potatoes, fruit trees, vegetables and lawns.


In addition to not mixed with milk oil, azoxystrobin has another problem that must be controlled is drug damage. Viscosity, solubility and permeability are important indexes of azoxystrobin, and there is a close relationship among them. Especially because of its strong internal absorption and cross layer conductivity, it is very easy to produce drug damage without the aid. In this case, the plant protection industry has a common sense that azoxystrobin pesticide cannot be mixed with organosilicon synergist. Because it needs to be controlled in the first place, further aggravation is counterproductive. From this point of view, the more prominent these properties are, the more dangerous they are. Therefore, in the production process, the general manufacturers will consciously and unconsciously emphasize the safety of drug use, and realize the function of performance "brake" through relevant auxiliaries to prevent drug harm.


Azoxystrobin has been widely developed and applied, which has brought real disease prevention and control benefits to agricultural production, but also from time to time heard the voice of drug damage from all over the country. For example, in the protected tomato or orchard, there have been drug damage caused by the unreasonable use of azoxystrobin. Therefore, in the product promotion, overemphasizing the performance index of azoxystrobin, exaggerating some of them, and not paying attention to the scientific and safe use of drugs, may cause the risk of drug harm due to improper use.


Precautions for use of azoxystrobin:


(1) azoxystrobin should not be used too many times and should not be used continuously. In order to prevent drug resistance, it is strictly prohibited to use it more than 4 times in a growing season, and should be used alternately with other agents according to the disease type. For example, when the climate is particularly conducive to the occurrence of disease, the vegetables that have used azoxystrobin will also suffer from mild disease. Other fungicides can be selected for targeted prevention and treatment.


(2) it can be used before the occurrence of crop diseases. It can also be used in the critical period of crop growth, such as leaf expansion, flowering and fruit growth. It is necessary to ensure that sufficient liquid volume is sprayed and the mixture should be well mixed and sprayed.


(3) it is forbidden to use on apples and pears. When using on tomatoes, it is forbidden to use drugs in cloudy days, and it should be used in sunny morning.


(4) pay attention to the safety interval, 3 days for tomato, pepper, eggplant, 2-6 days for cucumber, 3-7 days for West (sweet) melon and 7 days for grape. Source: Xuchang agricultural technology station
