Misunderstanding 1: blindly chasing new and seeking different farmers like to use new pesticides and fertilizers. Taking pesticides as an example, although the use of new pesticides can prevent the resistance of certain pests and diseases, many pesticides are mainly used as a compounding agent, which will increase the amount of use and cause phytotoxicity. At the same time, some pesticides and fertilizer products have not been promoted, and their effects are not well understood, and problems are prone to occur.
Misunderstanding 2: Pursuit of quick-acting Some farmers like to choose quick-acting fertilizers and pesticides to pursue rapid effects. For example, some foliar fertilizers contain hormones or nitrogen-based fertilizers, which are effective after a few days of spraying, and are highly respected by some vegetable farmers. However, this rapid growth is sometimes only prolonged, and it is highly likely to cause dystrophic growth and reproductive growth, resulting in a decline in yield. Another example is that some biological pesticides such as avermectin insecticides and Bt, etc., are not easy to show obvious effects because they only kill eggs or inhibit insects, and are often not recognized by vegetable farmers. Many vegetable farmers hope that the pests will die when they are in contact with the drugs. However, the serious consequence of pursuing the quick-acting effect is that the pesticide residues in the products exceed the standard.
Misunderstanding 3: Excessive application of many pesticides, the use of pesticides, the application of organic fertilizers and chemical fertilizers is several times or even dozens of times of the applicable amount, often causing phytotoxicity and fertilizer damage, which not only increases production costs, but also seriously affects the quality of vegetables. And the yield, while the excessive application of one or several fertilizers can also cause salinization of the soil.
Misunderstanding 4: It is impossible to prescribe the right medicine and rational fertilization. This is a common problem in current production. Many vegetable farmers cannot diagnose correctly because of lack of plant protection and soil and fertilizer knowledge, but blindly use drugs and fertilizers. Especially when vegetables lack certain nutrients, it is often wrong to apply another fertilizer, which not only cannot supplement nutrition, but may cause single salt damage.
Misunderstanding 5: Mixing a variety of pesticides Many vegetable fungicides are mixed with micro-fertilizers, insecticides , and viricides, which not only affects the efficacy, but also causes phytotoxicity and affects crop growth.
