Foliar fertilizer and pesticides need to be careful not to mix and mix
Foliar fertilizer has quick effect, good effect and convenient use, and is popular among the farmers. However, it is not appropriate to add foliar fertilizer every time you spray. Although foliar fertilizer is a good thing, it can not be used in large quantities. Foliar fertilizer should be used as the auxiliary for base fertilizer and top dressing. Root absorption is the main source of crop nutrients. Therefore, foliar fertilizer can not be used or abused, and unreasonable use may have serious consequences. Special caution should be taken when mixing foliar fertilizers. For example, mancozeb (including zinc and zinc) is the main type of fungicide. In the process of disease prevention, manganese-zinc foliar fertilizer is applied to the crop inadvertently, so the situation of manganese-zinc poisoning often occurs. For example, the leaves of the middle and lower leaves of the eggplant are yellow, the red and brown rust spots on the back of the tomato leaves, and the leaves are prematurely aged and brittle. In addition, most foliar fertilizers are compound type, and there are at least 5-6 kinds of 16 elements. In addition, amino acids, alginic acid, and hormones are added, and the active ingredients are complicated. Most fungicides and insecticides cannot add foliar fertilizer, because the metal elements in the foliar fertilizer often react with pesticides, as long as they appear turbid, precipitated, clear, and insoluble after mixing, and the pesticides fail. If the crop is damaged, there is no harm in it. It is recommended that the foliar fertilizer should not be mixed as much as possible. Another is to pay attention to the order of the pesticide and foliar fertilizer. Foliar fertilizers, especially nutrient foliar fertilizers, are mostly in the form of ions. However, if the ion concentration is too high, it is easy to cause the pesticide to react with it, and precipitation may occur, which may affect the drug effect. Therefore, when pesticides and foliar fertilizers are used together, the foliar fertilizer should be diluted with water, and then the other pesticides should be mixed in the order of wettable powder, suspending agent, water agent and emulsifiable oil to reduce the reaction such as precipitation. The possibility is less risky. The second dilution before the pesticide is added can further reduce the risk. When foliar fertilizer is mixed with pesticides, it should be used as needed, and should not be retained before use.
