Can different pesticides be mixed? Many people think that different types of pesticides can be mixed. In fact, not all pesticides can be mixed. The following points should be noted when mixing pesticides:
(1) pH is an important factor affecting the effectiveness of each component. Under alkaline conditions, carbamate, pyrethroid vinegar insecticide , thiram, dexame ring and other dithiocarbamic acid fungicides are easy. Hydrolysis or complex chemical changes occur, destroying the original structure. Under acidic conditions, 2,4-D sodium salt, 2 methyl 4-chloro sodium salt, amitraz and the like will be decomposed, thereby reducing the efficacy.
(2) Organic sulfur and organophosphorus pesticides cannot be mixed with pesticides containing copper preparations. For example, dithiocarbamate fungicides, 2,4-D salt herbicides are mixed with copper preparations, and lose their activity due to complexation with copper ions.
(3) Microbial-derived insecticides and systemic organophosphorus pesticides cannot be mixed with fungicides .
(4) Mixing of emulsifiable concentrate or wettable powder requires no delamination, oil slick, precipitation, etc.
(5) The chemical changes of the active ingredients in the composition of the mixture may cause phytotoxicity. For example, the combination of the stone sulphur mixture and the Bordeaux mixture may produce harmful copper sulfide, and also increase the soluble copper ion content; the enemy, butachlor and the like cannot be combined with the organic phosphorus. Mixing with carbamate insecticides.
(6) Insecticide mixture includes: enemy powder, enemy powder, enemies, anti-mite, complex fruit and so on.
(7) Insecticides and fungicides are mixed and mixed in the form of chlorpyrifos plus glutinous rice glutinous rice, dimethoate, and methamidophos, and most of them are currently used.
(8) There are fewer varieties of insecticides, fungicides and herbicides .
(9) There are many varieties of fungicides, mainly mixed with double seed, metalaxyl manganese sulfate, polysulfide suspension, and antibacterial.
(10) Plant growth regulators are mixed in a small variety. For example, imipenem is mixed with chlormequat, and gibberellin is mixed with naphthalene acetic acid.
