How to Use Agrochemicals Scientifically?

What Are Agrochemicals?

Agrochemicals refer to the inputs in agricultural production such as fertilizers, pesticides, veterinary drugs, and growth regulators. Their use can promote the production of edible agricultural products and play an important role in the sustained and rapid development of agriculture.
Agricultural chemicals can be divided into three categories: fertilizers, pesticides, and agricultural films. Chemical fertilizer is the abbreviation of chemical fertilizer, which refers to the fertilizer containing one or several nutrients required for the growth of crops made by chemical and (or) physical methods. It is mainly used to improve soil fertility and increase crop yield per unit area. The most common are nitrogen fertilizers, phosphate fertilizers, and potash fertilizers, which are chemical fertilizers that plants need more. Pesticides refer to various sterilization, insecticide, weed control, and other drugs used to promote and protect the healthy growth of crops. The agricultural film is mainly used for mulching cultivation technology, which makes a huge contribution to increasing agricultural production and income and producing off-season crops.

Scientific Use of Agrochemicals

1. Increase the publicity of scientific use of agrochemical knowledge
   In view of the current situation that the majority of farmers lack knowledge of agrochemicals, it is necessary to vigorously publicize relevant scientific knowledge, enhance people's understanding of agrochemicals, achieve scientific farming, accurate and timely control of pests and diseases, and make farmers fully aware of the best use of agrochemicals. Application timing and application techniques.

2. Carry out research on new agrochemicals
   Efforts will be made to develop new products, increase recycling of recyclable products, and advocate green and sustainable agriculture on the premise of low toxicity, high efficiency, greenness, and safety. At present, slow/controlled release fertilizers are favored as a new type of chemical fertilizers and are known as ideal fertilizers in the 21st century. They have the characteristics of less environmental pollution, good fertilizer effect, and high economic benefits. The development of new pesticides has turned in the direction of low toxicity, low residue, high specificity, and no collateral damage; botanical pesticides, microbial pesticides, and sanitary pesticides have begun to be used in agricultural production. In view of agricultural film pollution, the concept of "degradable plastic" proposed by the United States and Japan has become a research hotspot since the 1970s and has achieved remarkable results and put it into the application, such as photodegradable agricultural film, biodegradable agricultural film, cellulose Agricultural film, etc.
