Significance of Pesticide reduction

Pesticides are more or less used in the process of planting fruit trees, vegetables, or saplings, but because pesticides are highly polluting and seriously affect the growth of water and other crops, it is necessary to reduce the use of pesticides. What is the significance of pesticide reduction?

What is the significance of pesticide reduction?

1. Improve the quality and safety of agricultural products. Pesticide pollution and excessive residues of agricultural products is an important factor affecting the quality and safety of agricultural products in China. To achieve the scientific reduction of the use of pesticides will, to a certain extent, reduce the pollution of pesticides on agricultural products, and will also effectively control the excessive pesticide residues of agricultural products, which will greatly improve the quality and safety level of China's agricultural products and enhance the international competitiveness of agricultural products.

2. Protect the agricultural ecological environment. Pesticides are an important aspect of agricultural and rural non-point source pollution. For a long time, the extensive use of pesticides not only caused serious pollution to farmland, but also caused damage to agricultural water ecological environment as well as pesticides into soil, water and atmosphere. The scientific reduction of pesticide use will reduce the impact of pesticides on the environment from the source, which is of great significance for the protection of agricultural ecological security.

3. Reduce the occurrence of drug damage and drug resistance of crops. If pesticides are irrationally used, especially excessive use, it is easy to cause crop drug damage. In recent years, the unreasonable use of herbicides and other pesticides has led to frequent crop drug damage accidents. At the same time, the misuse, abuse and overuse of pesticides are the main causes of drug resistance of Cordyceps sinensis. The scientific reduction of pesticide use will effectively prevent the occurrence of crop drug damage and delay the development of drug resistance.

4. Promote the increase of farmers' income. The scientific reduction of pesticide use can not only ensure the increase of agricultural production, but also reduce the cost of pesticide use, so it is also conducive to agricultural efficiency and farmers' income.

Second, how to use pesticides?

1. Powder. Powder is insoluble in water, generally can not be sprayed with water, low concentration powder can be used for powder spraying, high concentration powder is mostly used for the preparation of poisonous soil, poison bait, seed dressing and soil treatment. Powder should be used in the morning and evening when there is no wind or the wind is weak.

2. Wettable powder. It has strong hygroscopicity, can be dispersed or suspended in water after adding water, and can be used as spray, poison bait and soil treatment.

3. Soluble powder. This kind of pesticide can be sprayed or poured directly with water.

4. Emulsion. After adding water, it will turn into emulsion, which can be used for spraying, splashing, seed dressing, seed soaking, poisonous soil, stem coating and so on.

5. Oil. It is a chemical that can be directly used for spraying. It belongs to a special matching pesticide for ultra-low volume spray and cannot be added with water when in use.

6. Granules and granules. The pesticide dosage form made of pesticide raw drugs and fillers is not easy to produce drug damage, and it is mostly used for heart leaf filling, sprinkling, spot application, seed dressing, ditch application and so on.

7. Sustained-release agent. The slow release of pesticides during use can effectively prolong the efficacy period; this pesticide has a longer residual period and can reduce pollution and toxicity, and its usage is the same as that of granule pesticides.

8. Smoke agent. It is a fine powder or ingot made of pesticides, fuels, oxidants, combustion aids, etc. When heated, this kind of pesticide will vaporize and condense into solid particles in the air to form smoke, which is mainly used to control forest, facility agricultural diseases and pests and warehouse pests.
