The compounding and mixing of pesticides means mixing two or more kinds of pesticides together to prepare a preparation or mixing them before use. At present, compound pesticides are rapidly developed and have many varieties, showing certain superiority and vitality. So what do you need to pay attention to when compounding pesticides?
1. The mixed pesticides cannot be chemically changed. The chemical structure and chemical properties of the active ingredients of the pesticides are the basis of their biological activities. Therefore, when using the pesticides, special attention should be paid to whether the active ingredients and emulsification properties after mixing change. Because this directly affects the efficacy of the drug. Therefore, the mixing of pesticides is not a simple mixing, but a scientific way of chemical structure and properties, through verification to ensure the safety of humans and animals, the environment, to prevent or delay the emergence of resistance to pests.
2. The physical properties of pesticides mixed in the field should remain unchanged. If delamination, flocculation and precipitation occur after mixing or the suspension rate is lowered or even crystallized, it cannot be mixed.
3. After compounding and mixing, the toxicity to human and livestock, poultry and fish, and the damage to natural enemies and other beneficial organisms should be reduced. Some pesticides have improved efficacy after mixing, but the toxicity has also increased. For example, malathion is safe for humans and animals and is easily decomposed by biological enzymes in humans and animals. However, when used in combination with dichlorvos and trichlorfon, dichlorvos and trichlorfon inhibit the activity of the enzyme but produce higher toxicity. Therefore, this situation cannot be mixed.
4. After compounding and mixing, it must have different modes of action and control targets to achieve the effect of expanding the insecticidal spectrum. For example, pesticides are mixed with fungicides, disease prevention and pest control, insecticides and ovicidal agents are mixed, and eggs are treated.
5. The pesticide residue in agricultural and sideline products after compounding and mixing should be lower than that of single pesticide.
6. After compounding and mixing, farmers should reduce the cost of use.
In short, as long as the above points are guaranteed, the pesticides can be combined to achieve better results.
