Orchard pesticide mixing precautions

1. pH is an important factor affecting the effectiveness of each component. Under alkaline conditions, dithiocarbamate fungicides such as carbamate, pyrethroid insecticides, thiram, and dexame ring are prone to hydrolysis or complex chemical changes, thereby destroying the original structure. Under acidic conditions, 2,4-D sodium salt, 2 methyl 4-chloro sodium salt, etc. will decompose, thereby reducing the efficacy.

2. Organic sulfur and organophosphorus pesticides cannot be mixed with pesticides containing copper preparations. For example, a dithiocarbamate fungicide and a 2,4-D salt herbicide are mixed with a copper preparation, and are inactivated by complexation with copper ions.

3. Microbial source insecticides and systemic organophosphorus pesticides cannot be mixed with fungicides.

4, emulsifiable or wettable powder mixed, requires no stratification, oil slick, precipitation and so on.

5, should avoid the occurrence of phytotoxicity of the mixture, chemical changes in the composition of the mixture, may cause phytotoxicity, such as stone sulphur mixture mixed with Bordeaux mixture can produce harmful copper sulphide, will also increase the content of soluble copper ions; butachlor Can not be mixed with organic phosphorus, carbamate insecticides.

6, insecticide mixture: a rival powder, enemy powder, enemies emulsifiable concentrate, anti-Qi Ling, complex fruit and so on.

7. The mixed and mixed forms of insecticides and fungicides include: killing pine and adding different rice glutinous rice, dimethoate, and methamidophos, and most of them are currently used.

8. Insecticides, fungicides and herbicides are mixed in a small variety.

9. There are many varieties of fungicides, mainly including double seed dressing, metalaxe carbazide, polysulfide suspension, and antibacterial.

10. There are fewer varieties of plant growth regulators. For example, imipenem is mixed with chlormequat, and gibberellin is mixed with naphthalene acetic acid.
