Aphid extinguishing liquor and electrothermal aphid extinguishing method employing same for preventing and controlling aphid of facility crops

Abstract

The invention relates to an aphid extinguishing liquor and an electrothermal aphid extinguishing method employing the same for preventing and controlling aphid of facility crops. The method comprises the following steps: preparing an electrothermal aphid extinguishing liquor; disposing the electrothermal aphid extinguishing liquor; performing electrothermal aphid extinguishing; judging whether to stop aphid extinguishing. The aphid extinguishing liquor comprises the following components by weight percent: 1-2 percent of chlorpyrifos-methyl, 1-30 percent of dimefluthrin, 1-5 percent of a stabilizer, 1-5 percent of a synergistic agent, 1-5 percent of a volatile modifier and 53-95 percent of a solvent. The electrothermal aphid extinguishing method is simple, convenient and safe, is easy to operate, and has a good control effect; effective components of the aphid extinguishing liquor are quick in diffusion, strong in penetration and uniform in distribution and can produce an excellent prevention and cure effect.

Description

technical field [0001] The invention relates to a method for killing aphids and the liquid used for killing aphids, in particular to an electric method for killing aphids with electric heat for preventing and controlling aphids of facility crops and the solution for killing aphids, which can effectively kill aphids of facility crops and belongs to the compounding and Field of application technology. Background technique [0002] Aphids are pests of the family Aphididae of the order Homoptera. They often gather in the leaves, tender stems, flower buds, terminal buds and other parts of plants to pierce and suck juice, causing the leaves to shrink, curl, and deform. The honeydew secreted by aphids can also induce soot, viral diseases and attract ants. With the adjustment of agricultural planting structure, the planting area of ​​facilities is expanding year by year, and the occurrence and damage of aphids and viral diseases transmitted by them are becoming more and more seriou...

AI Technical Summary

Problems solved by technology

[0003] For the increasingly serious occurrence of aphids in facility agriculture, people have to rely on spraying chemical pesticides to maintain production, but this is very inconsistent with the development of green agriculture, and the existing spray control technology itself has many problems, and the expected control effect cannot be obtained

There are mainly the following problems in the existing technology: ①The traditional large-capacity spraying control technology increases the humidity in the facility environment, resulting in more serious plant diseases; Drops cannot be well distributed and deposited on the back of plant leaves, stems and other sheltered areas, resulting in poor control effects; ③Due to the serious occurrence of plant diseases and insect pests under the facility conditions and overlapping generations, frequent control operations are required. On the one hand, it increases Labor costs, on the other hand, lead to excessive use of pesticides, excessive pesticide residues and frequent occurrence of personnel poisoning

Since the patented Chinese medicine liquid is directly diluted by the preparation and then added to the heating device, it does not use a preparation system specially supplied with heat to volatilize, the active ingredients of the medicine cannot be released continuously and evenly, and it is difficult to achieve the ideal control effect
