Some farmers' friends, when applying pesticides and fertilizers, are prone to enter the following misunderstandings due to lack of corresponding knowledge, resulting in loss of agricultural production.
First, the pursuit of quick-impact. Many vegetable farmers always like to choose quick-acting when they choose fertilizer. The reason is that the effect will be obvious soon after use, but it is also easy to cause the plant to grow. The correct approach is to rationally select the fertilizer variety based on the plant's overall developmental needs. The serious consequence of the rapid effect of vegetable farmers in controlling pests and diseases is that the use of highly toxic, high-toxic and high-residue pesticides in some places still exists, and the pesticide residues in the products produced exceed the standard.
The second is to blindly pursue new differences. At present, there are many types of pesticides and fertilizers on the market, and the quality is not good. Taking pesticides as an example, many new pesticides introduced on the market are mainly compounding agents. When used, farmers will blindly increase the amount of use and cause phytotoxicity. Sometimes some pesticide and fertilizer products have not been widely tested and tested. The problems in the use effect have not been discovered in time, and they are prone to problems when used.
The third is to believe too much about the efficacy of certain pesticides and fertilizers. Many pesticides and fertilizers have a scope of application. When buying, they often see that they are bought and used as long as they are marked with more control effects. If some pesticides indicate that they can cure many diseases such as fungi, bacteria, viruses, etc., they will be purchased as good pesticides, and their actual control effect is often poor.
The fourth is excessive application. Excessive application of pesticides can cause phytotoxicity, and excessive application of chemical fertilizers often causes fertilizer damage, which leads to crop root burning affecting yield. It also causes salinization of the soil.
The fifth is improper use. When applying fertilizer, choose the appropriate method of use, such as spraying or spraying fertilizer at different growth stages, and whether the organic fertilizer is fully decomposed. If not applied in a proper way, it will cause fat damage.
Sixth, it is impossible to prescribe the right medicine and unreasonable fertilization. This is a common problem in the current vegetable production. Sometimes blindly using micro-fertilizers, there will be cases where vegetables lack certain elements and supplements are another element. Not only can the problem not be solved, but it may aggravate the condition.
Seven is a mixture of a variety of pesticides. Many vegetable farmers' fungicides are mixed with several varieties such as insecticides and micro-fertilizers, which not only affect the efficacy of the drugs, but also easily cause phytotoxicity and cause large losses.
