The use of fungicides provides horticultural protection against diseases and high yields. The drug Quadris is one of the most effective ways to combat fungal infections. It is used for preventive treatments, as well as to get rid of existing diseases.
Features of the fungicide
Quadris is a fungicide produced in Switzerland. The drug acts against fungal diseases. Quadris has the form of a concentrated suspension, which is packaged in 5 or 6 ml ampoules. The drug can be purchased in plastic containers with a volume of 1 liter.
The active substance is azoxystrobin, which belongs to the class of strobilurins. The drug has a destructive effect on the fungus. Then azoxystrobin breaks down into safe components: oxygen, carbon, hydrogen and nitrogen.
As part of Quadris, there are no traditional substances that are found in pesticides: sulfur, phosphorus, metal ions. The decay products are safe, do not have a harmful effect on plants, soil and atmosphere, do not accumulate in fruits and shoots.
If the dosage is exceeded, then as a result, the growth of crops will slow down and the yield will decrease. It will also increase the resistance of the fungus to the fungicide. When the dosage is underestimated, the effect of using the drug is significantly reduced.
The main analogues are the drugs Consento, Prozaro, Folikuo, Strobi, which have a similar effect on fungal infections.
