Pay attention when mixing chemical pesticides
Scientific and rational compounding of pesticides can improve the control effect, expand the control object, delay the resistance, and reduce the cost of prevention. The main types of pesticides are: insecticide plus synergist, insecticide plus insecticide, fungicide plus fungicide, herbicide plus herbicide, etc., but must not be combined arbitrarily, blindly pick "two in one", "Three in one", this should consult or consult the relevant information, or adhere to the principle of mixing and testing first, otherwise it is counterproductive, it may increase toxicity, increase the resistance of disease, insects, and even the harmful effects of vegetable phytotoxicity.
