With the increasing number of pesticides and fertilizers, the combination of the two is very common. Mixed scientific and reasonable, can save labor, improve work efficiency, fertilizer efficiency and efficacy, but if mismatched, it will not only reduce the effect, but even cause unexpected harm. Mix pesticides with pesticides â— Under alkaline conditions, carbamate, pyrethroid vinegar insecticides, thiram, dexame ring and other dithiocarbamate fungicides 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, amitraz and the like will be decomposed, thereby reducing the drug effect. â—Organic sulfur and organophosphorus pesticides cannot be mixed with pesticides containing copper preparations. For example, dithiocarbamate fungicides, 2,4-D salt herbicides are mixed with copper preparations, and lose their activity due to complexation with copper ions. â— Microbial source insecticides and systemic organophosphorus pesticides cannot be mixed with fungicides. â—Alcohol or wettable powders are mixed, requiring no delamination, oil slick, precipitation, etc. â—The chemical changes of the active ingredients in the composition of the mixture may cause phytotoxicity. For example, the combination of the stone sulphur mixture and the Bordeaux mixture may produce harmful copper sulfide, and also increase the soluble copper ion content; the enemy, butachlor and the like cannot be combined with the organic phosphorus and the amino group. Mixed with formate pesticides. â—Insecticides and fungicides are mixed and mixed in the form of chlorpyrifos plus glutinous rice glutinous rice, dimethoate, and methamidophos, and most of them are currently used. There are fewer varieties of conditioners mixed. For example, ampicillin is mixed with chlormequat, and gibberellin is mixed with naphthaleneacetic acid. Fertilizer and fertilizer mix Superphosphate can not be mixed with alkaline fertilizers such as plant ash, lime nitrogen, lime, etc., otherwise it will reduce the effectiveness of phosphorus; phosphate mineral powder, bone powder and other insoluble phosphate fertilizers can not be mixed with alkaline fertilizer such as grass ash, lime nitrogen, lime, etc. Since the organic acid in the soil is neutralized, the poorly soluble phosphate fertilizer is more difficult to dissolve, and the crop cannot be absorbed and utilized. Alkaline fertilizers such as calcium magnesium phosphate can not be mixed with ammonium nitrogen fertilizer, which will increase ammonia volatilization and reduce fertilizer efficiency. Chemical fertilizers cannot be mixed with bacterial fertilizers because they have strong water absorption, corrosiveness and volatility. If they are mixed with bacterial microorganisms such as rhizobia, they will kill or inhibit live bacteria and invalidate bacterial fertilizers. Unfertilized farmyard manure cannot be mixed with ammonium nitrate. If mixed with ammonium nitrate, the unfertilized farmyard manure is damaged by nitrogen during the decomposition and decay process, reducing fertilizer efficiency. Mixing pesticides with fertilizers To identify whether plant growth regulators can be mixed with other pesticides and fertilizers, the simplest method is to mix agricultural plant growth regulators with pesticides or fertilizers in the same container and make a solution, if there is no oil slick, flocculation , precipitation or discoloration, fever, bubble generation, etc., indicating that they can be mixed. Pesticide and fertilizer compounding rules It does not destroy the physical properties and maintains the original physical properties, and does not cause emulsification, suspension rate reduction, delamination, flocculation, precipitation, and crystallization of active ingredients. No adverse chemical reactions such as acid-base neutralization, precipitation, hydrolysis, alkali hydrolysis, acid hydrolysis, salting out or redox occur between the bad chemical reaction mixtures. After adding no toxicity and residual active pesticides, it is required to increase the toxicity to ensure the safety of humans and animals. Generally, moderately toxic pesticides are mixed with low- or low-residue pesticides to reduce toxicity or residue and reduce pesticide residues in fruits. The method of use is as consistent as possible. The components in the mixture are relatively consistent in terms of time of action, site of application, and subject to be used, and can fully exert their respective effects. First try and then promote the test in a small area, and then mix it when it proves that there is no adverse effect. Disclaimer: Some articles on this website are transferred from the Internet.
