The pyrethroid pesticides (quick killing, enemy killing, kung fu, etc.) are mixed with various organophosphorus insecticides (malathion, dimethoate, omethoate, etc.), have synergistic effects, and can Delay pests to produce drug resistance.
Mixed application of bacterial species. The results of the study showed that systemic fungicides, such as carbendazim, thiophanate-methyl, thiophanate-methyl, and natural protective agents (sulfur, etc.) or artificially synthesized protective agents, can be used to avoid resistance to pathogenic bacteria.
Mixed herbicide varieties. If there are many species of weeds in the field, in order to increase the herbicidal range of herbicides, two or more herbicides may be mixed and applied according to the needs of crops, weed species, and farming systems. For example, the combination of diterpenoid and isoproturon can increase the control effect of wild oats and broadleaf weeds; the combination of herbicides and dimethyl tetrachlorine can expand the range of herbicides.
