How to use fungicide better Caution Drug mix:
Many fungicides for alkaline pesticides, so it can not be mixed with alkaline substances easy to decompose failure of pesticides, such as Bordeaux liquid, stone sulfur mixture and so on alkaline can not be mixed with 1605, Dimethoate, dichlorvos, otherwise it will cause damage to both.
There are some fungicides such as carbendazim, Beauveria bassiformis and so on can not be mixed with Bordeaux liquid, stone sulfur mixture, tolbuzine and other fungicides, will also cause insecticidal (bacteria) microbial loss of physiological activity and insecticidal (bacteria) ability and failure.
In addition, some mixed to produce chemical reactions and drug damage should not be confused. Of course, not all fungicides can not be mixed with other pesticides, a few fungicides mixed with pesticides can also play a synergistic role. For example, dimethoate mixed with acidic bactericidal properties such as Dyson zinc or wettable sulfur or colloidal sulfur will not affect the effect of drug efficacy, but also enhance the effect of drug efficacy.
How to use fungicides better pay attention to avoid resistance:
The use of fungicides also has the problem of resistance to crop diseases. Long-term use of a single agent (mainly internal fungicides) will lead to resistance to the pathogen, even if repeated drug use is of no use, and even worse. In order to avoid disease resistance, it is necessary to use different types of drugs alternately (alternately) on the basis of scientific selection of pesticides, and it is strictly prohibited to use one pesticide alone for a long time.
