It is not advisable to use too much medicine to kill insects
In rural areas, farmers often encounter such a phenomenon: when applying drugs, they do not know what pesticides they use, nor do they know how many times the pesticide should be blended, only know how many caps (pesticide caps) are mixed with a bucket of water. This is a true portrayal of the use of pesticides by most Chinese farmers today. Of course, this situation is related to the low level of education of farmers themselves, and it is also insufficient publicity and popularization of pesticide knowledge, or lack thereof. in the past, farmers were familiar with the names of many pesticides. with the withdrawal of batches of highly toxic pesticides from the market, especially some organophosphorus highly toxic pesticides, many environmentally friendly pesticides and new formulations appeared. farmers knew little or nothing about these new pesticides. including many pesticide dealers, they have not really changed their thinking, have not really realized the significance of banning highly toxic pesticides, and even operate with the mentality of a bystander: farmers love to use whatever medicinal drugs, farmers love to use how they use them, as long as they can sell drugs and earn money. In addition, pesticide dealers own quality is not high, lack of relevant knowledge, do not understand learning, only an irresponsible, take for granted attitude to buy and sell pesticides, think farmers as long as the drug killed insects on the line, so some dealers deliberately let farmers increase the dosage, according to the size of pesticide caps, randomly teach farmers a bucket of water with a few caps of medicine, caps small let farmers against 3 caps, 4 caps, or even against 5 caps 6 caps. many dealers are afraid that farmers will understand, believing that the more farmers do not understand, the more they will believe what they say, which will be more conducive to their random sales promotion. for example, farmers clearly have a drug for aphid control, but the dealer deliberately says that the drug cannot be used and asks farmers to buy another drug he recommends. In this way, one pest sells one pesticide, which makes farmers increase investment and also destroys the environment.

Two key points of insecticide spraying
First, according to the climate characteristics and the law of diurnal activity of pests, the pesticide should be applied in a favorable period of time. The suitable time of application is from 9 am to 10:00 and after 4 pm. Because at 9: 10 in the morning, the dew on the crop leaves is dry, and it is the time when sunrise pests are most active. When the medicine is applied at this time, it will not be because of dew.

In spring and summer, fruit trees are prone to various diseases (physiological diseases, pathogen toxin diseases) before and after flowering. At this stage, in addition to the necessary chemical prevention, timely application of phosphorus and potassium fertilizer is also a better choice. But many fruit growers tend to apply only nitrogen fertilizers (such as urea, high nitrogen) during the Spring Festival.
