Problems solved by technology

The grains spoiled by pests and diseases in the world account for 20% to 40% of the total harvest every year. In order to deal with these pests, more than 2 million tons of pesticides are produced in the world every year for prevention and control. Most of the pesticides used in my country are chemical synthetic products. Organic substances containing chlorine and phosphorus can effectively kill pests, but their residues on food, vegetables, and fruits have caused great harm to human health
For a long time, due to the extensive use of chemical pesticides, not only the pollution of the ecological environment has been caused, but also some diseases and insect pests have developed a certain degree of resistance, resulting in a further increase in the use of chemical pesticides. At the same time, when chemical pesticides pollute agricultural by-products and groundwater Occurs and poses a certain degree of threat to human beings

Embodiment 1

[0012] Preparation:

[0013] 1. Take 200g of fresh tea leaves and 300g of tobacco leaves, and cut them into pieces;

[0014] 2. Add an appropriate amount of water and heat it to 80°C in an iron pot, add plant fragments, continue heating, stir while heating, and cook for 30 minutes;

[0015] 3. After cooling the boiled liquid naturally, filter it (the filtered clear liquid maintains a volume of 2L);

[0016] 4. Bottle and package the filtered clarified liquid.

Embodiment 2

[0017] Embodiment 2 The experiment of pesticide control aphid of the present invention

[0018] The pesticide stock solution obtained in Example 1 was diluted, and water was used as a control treatment, and each treatment was repeated 3 times, and 30 aphids were treated each time. The specific method is as follows: put the aphids in each petri dish, spray them with the medicine or clear water of the treatment concentration, then place them for cultivation at room temperature, and check the death of the aphids under a binocular dissecting microscope after 12 hours. As can be seen from Table 1, the stock solution diluted 40 times has the best insecticidal effect.

[0019] The control effect of different stoste dilution concentrations of table 1 on aphids
