Problems solved by technology

Over the years, a large number of chemical synthetic products have been used, many organic substances containing chlorine and phosphorus, although they can effectively kill pests, but the residues on the fruit have caused great harm to human health
The long-term use of chemical pesticides has also caused the resistance of pests, and the pesticides contain heavy metal elements such as chlorine and copper, which seriously pollute the environment and agricultural products

Embodiment 1

[0014] Preparation:

[0015] 1. Take 150g of fresh pepper leaves, 200g of tomato leaves, and 200g of tobacco leaves, and cut them into pieces;

[0016] 2. Add 3L 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;

[0017] 3. After cooling the boiled liquid naturally, filter it;

[0018] 4. Bottle and package the filtered clarified liquid.

Embodiment 2

[0019] Example 2 Experiments on the control of persimmon scale by the pesticide of the present invention

[0020] The concentration of the pesticide stock solution obtained in Example 1 was diluted, and water was used as a control treatment. Each treatment was repeated 3 times, and 20 persimmon scales were treated each time. The specific method is: put the cotton scale in each culture dish, spray the medicine or clear water of the treatment concentration to it, then place it at room temperature for cultivation, and after 12 hours, check the death situation of the cotton scale under the binocular dissecting microscope (using The dissecting needle touches the persimmon scale lightly, and the person who does not move is considered dead). As can be seen from Table 1, the stock solution diluted 20 times has the best insecticidal effect.

Abstract

The invention relates to a pesticide prepared from plants and used for controlling persimmon tree pests. The pesticide is prepared from one or several main materials selected from plant pepper, potato, tomato, tobacco, and Solanum nigrum, and the above materials are subjected to a special boiling process to prepare the pesticide. The plant pesticide is low in toxicity and safe in usage, has no side-effects on human, livestocks, fruits and branches when the liquid pesticide is sprayed, and is wide in raw material sources and low in cost. Moreover, the pesticide can effectively control persimmon tree pests, and has substantial effects on controlling persimmon woolly coccid.

Description

technical field [0001] The invention relates to a biological pesticide, specifically, it is a pesticide for preventing and controlling persimmon tree insect pests made of one or more of plant chili, potato, tomato, tobacco and black nightshade as main materials, and has a certain effect on the prevention and control of persimmon scale Significant effect. Background technique [0002] Persimmon tree is one of the main fruit tree species in my country and has a long history of cultivation in China. Persimmon trees are highly adaptable, especially suitable for planting in vast mountainous areas. They are very popular due to their long age and high fruit yield. However, the occurrence of insect pests in the production process has a great impact on the quality and yield of fruits. Persimmon cotton scale is a kind of insect pest, which is widely distributed and harms the twigs, young leaves and fruits of persimmon trees. Nymphs and adults like to cluster under the fruit and in ...
