Fertilizers and pesticides are indispensable production materials for modern agriculture. In order to increase the output and quality, the number and types of chemical fertilizers applied by farmers are increasing. Among them, fertilizer spraying on leaves has become a technical measure frequently adopted by farmers, especially fruit growers and vegetable farmers, due to their small amount of fertilizer and quick results.

On the other hand, farmers must also regularly spray pesticides to control pests and diseases. Many people try to mix drugs and fertilizers and spray them together. The purpose is to save labor and improve work efficiency. For example, the “one spray, three sprays” technique popularized in the northern wheat heading stage is to mix triadimefon (or diniconazole), imidacloprid (or acetamiprid), and potassium dihydrogen phosphate in one spray. It can not only control wheat rust, powdery mildew and wheat aphids, but also reduce the incidence of lodging and dry hot winds, and has achieved good results in saving labor and increasing production and income. The reason why the “one spray and three defenses” technology is worthy of recognition and promotion is that the timing is appropriate. Because the wheat ear stage is exactly the critical period for preventing and controlling “two diseases and one insect” and supplementing panicle fertilizer and increasing grain weight, it is necessary to mix medicinal fertilizers. If it is changed in other periods, no targeted compounding may become a waste. As far as the scientific use of pesticides is concerned, the use of clean water to configure the liquid can best guarantee the efficacy.

The key to blending is that the chemical reaction between fungicides and insecticides and between drugs and fertilizers cannot affect the physical properties of drugs and fertilizers, such as solubility, suspension, emulsification, etc. . Of course, no chemical reaction will increase the toxicity of pesticides to humans, animals, plants, and decomposition of pharmaceutical fertilizers. From the perspective of maintaining efficacy, we already know that some pharmaceutical agents cannot be used in combination with alkaline pesticides (lithium-sulfur cocktails, Bordeaux mixture), such as flufenoxuron, diflubenzuron, acetamiprid, triazoni, and other pesticides. Manganese zinc, aluminum triethyl phosphate, caustic soda, metalaxyl, triadimefon, diniconazole, iprodione, kasugamycin, polyoxin, and cinnamidine. Reasoning, they can not and ammonium bicarbonate, grass ash, calcium magnesium phosphate fertilizer, diammonium phosphate, borax and ammonium molybdate and other alkaline or weakly alkaline fertilizer mix.

Some plant growth regulators, such as gibberellin, chlormequat, and ethephon, cannot be mixed with alkaline pesticides or fertilizers, otherwise they will break down. If herbicides are used in soil treatment, they are safe in most cases, especially when they are mixed together first and then finely moist (or water) and then mixed together before use. However, if it is used for stem and leaf treatment, it must be very careful. When it is used alone, a slightly larger dose or uneven spraying may incur phytotoxicity, so generally do not mix it with fertilizer. If the mixture is used, the herbicide must also be formulated as a mother liquor, and the fertilizer must be first mixed with water before mixing with the mother liquor.

Biological pesticides cannot be mixed with chemical fertilizers or bactericides, because chemical fertilizers and fungicides can kill the beneficial microorganisms and reduce the control effect. In addition, we must pay attention to the special provisions for the use of certain drugs, such as a bactericide known as bromo isocyanuric acid. It can treat both fungi, bacteria, and viruses. It is a rare good medicine, but it is also not suitable for mixing with other pesticides. Regulations and reasoning should not be mixed with chemical fertilizers.
