Fertilizers, pesticides and hormones are the main production materials for fruit production. With the development of society, technological progress and people's requirements for safe foods, producers will mix and apply two or more of chemical fertilizers, pesticides and hormones. Improving efficiency, saving costs, and increasing revenue are new trends in the future. The mixture of pesticides is mixed according to the scope of expanding prevention and control, eliminating the drug-resistant type and increasing the efficacy of the drug. However, it is necessary to grasp whether there is synergy or antagonism between the mixed drugs, and blind mixing will invalidate or even cause harm.
First, the principle of mixing 1. Do not destroy physical properties. After mixing, it can ensure normal efficacy or synergism, and maintain the original physical properties, so as to avoid emulsification, decrease in suspension rate, stratification, flocculation, precipitation, and crystallization of active ingredients. Powders cannot be mixed with wettable powders or soluble powders.
2. No adverse chemical reactions occur. No adverse chemical reactions such as acid-base neutralization, precipitation, hydrolysis, alkali hydrolysis, acid hydrolysis, salting out or redox reaction occur between the mixtures.
3. No reduction in toxicity and residual activity. The mixture does not cause toxic effects on fruit trees and products. After mixing pesticides, it is required not to increase toxicity, to ensure the safety of humans and animals, moderately toxic pesticides mixed with low-toxic or low-residue pesticides, which can reduce toxicity or residue and reduce pesticide residues in fruits.
4. Use the method as consistently as possible. The components in the mixture are consistent in the efficacy time, the application site and the object of use, and can fully exert their respective effects.
5. Try it first and then promote it. Tests are carried out in a small range and can only be mixed when it proves that there is no adverse effect.
Second, the combination of fertilizer and fertilizer 1. Superphosphate, phosphate rock, bone meal and human and animal manure and other farmyard fertilizer can not be mixed with grass ash, lime nitrogen, lime and other alkaline fertilizers. Otherwise, because the organic acid in the soil is neutralized, the poorly soluble phosphate fertilizer is more difficult to dissolve, reducing the effectiveness of phosphorus, and the fruit trees cannot be absorbed and utilized.
2. Alkaline fertilizers such as calcium, magnesium and phosphate fertilizers cannot be mixed with ammonium nitrogen fertilizer. Because alkaline fertilizers mixed with ammonium nitrogen fertilizers such as ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride, etc., will increase ammonia volatilization and reduce fertilizer efficiency.
3. Chemical fertilizers cannot be mixed with bacterial fertilizers. Because the fertilizer has strong water absorption, corrosiveness and volatility, if it is mixed with bacterial microorganisms such as Rhizobium, it will kill or inhibit the living cells and invalidate the bacterial fertilizer.
4. Unfertilized farmyard manure cannot be mixed with ammonium nitrate. If mixed with ammonium nitrate, the unfertilized farmyard manure will lose nitrogen during the process of decomposition and decay, otherwise the nitrogen will be damaged and the fertilizer efficiency will be reduced.
Third, the use of drugs and drugs 1. pH is an important factor affecting the effectiveness of each component. Under alkaline conditions, dithiocarbamate fungicides such as carbamate, pyrethroid vinegar insecticide, thiram, and dexame ring 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, etc. will decompose, thereby reducing the efficacy.
2. Organic sulfur and organophosphorus pesticides cannot be mixed with pesticides containing copper preparations. For example, a dithiocarbamate fungicide and a 2,4-D salt herbicide are mixed with a copper preparation, and are inactivated by complexation with copper ions.
3. Microbial source insecticides and systemic organophosphorus pesticides cannot be mixed with fungicides.
4. Mixing of emulsifiable or wettable powder requires no delamination, oil slick, precipitation, etc.
5. The mixture should be avoided. Chemical changes in the composition of the mixture may cause phytotoxicity. For example, the combination of stone sulphur and Bordeaux mixture can produce harmful copper sulphide and increase the content of soluble copper ions. Butachlor can not be combined with organic phosphorus or urethane. Mix pesticides.
6. Insecticide mixture: A enemy powder, B enemy powder, enemies emulsifiable concentrate, anti-Qi Ling, complex fruit and so on.
7. Insecticides and fungicides are mixed and mixed in the form of: killing pine, adding rice glutinous rice, dimethoate, methamidophos, and other rice, most of which are currently used.
8. Insecticides, fungicides and herbicides are mixed in a small variety.
9. There are many varieties of fungicides, mainly mixed with double seed, metalaxyl manganese sulfate, polysulfide suspension, and antibacterial.
10. Plant growth regulators are mixed with fewer varieties. For example, imipenem is mixed with chlormequat, and gibberellin is mixed with naphthalene acetic acid.
4. Mixed use of fertilizers and fertilizers Solid pesticides and fertilizers can generally be mixed directly. Solid-liquid mixing or liquid-liquid mixing should first consider the changes that may occur after mixing. After mixing, the application time and the depth of application must take into account the full effect of fertilizer efficiency and efficacy. The medicine and fertilizer mixture should be applied as base fertilizer. After the fertilizer and pesticide are mixed, the requirements for fertilizer application and the disease prevention, pest control and herbicide elimination of pesticides are often not completely unified. Therefore, the pesticides based on chemical fertilizers are mainly herbicides with less insecticides and fungicides. less.
1. Alkaline pesticides such as Bordeaux mixture, stone sulphur mixture, and rosin mixture cannot be mixed with ammonium nitrogen fertilizer or ammonium superphosphate such as ammonium carbonate, ammonium sulfate, ammonium nitrate or ammonium chloride to avoid ammonia volatilization or precipitation, thereby reducing Fertilizer effect.
2. Alkaline fertilizers such as ammonia, lime, grass ash, etc. cannot be combined with trichlorfon, dimethoate, acesulfame, methamidophos, methyl thiophanate, jinggangmycin, carbendazim, leaf mites, and pyrethrum Mix pesticides such as ester insecticides, otherwise it will reduce the efficacy. Because most organophosphorus pesticides are prone to decomposition failure under alkaline conditions.
3. Fertilizers cannot be mixed with microbial pesticides because chemical fertilizers are volatile and corrosive. If they are mixed with microbial pesticides such as acaricidal bacteria and green worms, they are easy to kill microorganisms and reduce the control effect.
4. Arsenic-containing pesticides cannot be mixed with potassium salts or sodium salts. For example, if calcium arsenate or aluminum arsenate is mixed with potassium salts or sodium salt fertilizers, soluble arsenic may be produced and phytotoxicity may occur. In all the mixed use of fertilizers, the most mixed fertilizers and herbicides, followed by pesticides, and less fungicides.
5. Plant growth regulators and fertilizers, especially high-yield, spray Shibao, foliar treasure, micro-fertilizer mixed, the effect is significant. For example, triacontanol is mixed with urea, potassium dihydrogen phosphate, ammonium molybdate, borax, and the like.
5. Before mixing the hormone with the medicine and fertilizer, put the agricultural hormone and the pesticide or fertilizer into the same container to make a mixed solution. If there is no oil slick, flocculation, sedimentation or discoloration, heat, bubble generation, etc. Mixed use.
6. Mixed water preparation, dilution of chemical fertilizers, pesticides and hormones should use clean, neutral soft water (refers to fresh water such as river water, river water, lake water, less calcium, magnesium ions, hardness of about 7.5 degrees), will not Chemical changes in pesticides and water, pesticide components are protected from damage, and the efficacy and control effects of pesticides are ensured to avoid phytotoxicity. If hard water (refers to water containing more calcium, magnesium, etc., such as well water, salt water, sea water, etc., the hardness is 18-20 degrees), the pesticide is diluted, and the calcium and magnesium ions in the water can reduce the suspension rate of the wettable agent. Or synthesizing calcium and magnesium precipitates with emulsions in emulsifiable concentrates, destroying the emulsifying properties of emulsifiable concentrates, reducing the control effect of pesticides, easily causing phytotoxicity to crops, and easily clogging the nozzles.
