Ultralow-volume liquid containing metaflumizone and indoxacarb

Abstract

The invention discloses ultralow-volume liquid containing metaflumizone and indoxacarb. The metaflumizone and the indoxacarb are taken as active components, and all the components are as follows in percentage by weight: 0.1-30 percent of the metaflumizone, 0.1-30 percent of indoxacarb, 1-15 percent of a solvent, 1-15 percent of an emulsifier, 1-5 percent of a wetting agent, 1-5 percent of a penetrating agent, and the balance of water. The ultralow-volume liquid disclosed by the invention is suitable for ultralow-volume spraying, low-volume spraying and electrostatic spraying, and has the advantages that the processing is convenient, the effect lasting period is long, the work efficiency is high, drug resistance is unlikely to be caused to a target, the environmental pollution is low, drugs and water are saved and the like; the ultralow-volume liquid is suitable of preventing and treating insect damages of crops such as vegetables, wheat, fruit trees, cotton and rice.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to an ultra-low volume liquid containing metaflumizone and indoxacarb, which belongs to the field of agricultural chemistry. Background technique [0002] Metaflumizone belongs to semicarbazone insecticides. Metaflumizone has a unique mechanism of action, has insecticidal activity itself, does not require biological activation, and has no cross-resistance with existing various insecticides. Metaflumizone has obvious control effects on chewing and biting insect species Lepidoptera and Coleoptera, such as common species include rice leaf borer, beet armyworm, cotton bollworm, cotton pink bollworm, cabbage butterfly, cabbage Noctuid moth, diamondback moth, cabbage borer, cutworm, rice stem borer, etc. have moderate control effects on leaf tortrix; metaflumizone has good control effect on coleopteran leaf beetle such as potato leaf beetle. The control of flea beetles and seed weevils is ...

AI Technical Summary

Problems solved by technology

[0005] 1. The work efficiency of the conventional spraying method is low, and the work efficiency per person is usually only 2-5 mu / day, which is difficult to meet the needs of large-scale planting

[0006] 2. Conventional spraying method requires a lot of water to control diseases and insect pests, usually 450-900L / ㎞ 2 However, in many areas far away from water sources and arid and water-scarce areas, conventional spraying methods are difficult to implement or cannot achieve the desired control effect.

[0007] 3. The medicines used in the conventional spraying method have a short duration of action. Since the dosage forms of the medicines used in the conventional spraying method are usually emulsifiable concentrates, water preparations, wettable powders, suspension concentrates, and water-emulsions, there are certain defects in use: due to the addition of a large amount of water to dilute , the concentration of the liquid medicine is very low, the surface tension is often high, and the adhesion, wettability, and permeability on the surface of the crop or target with a waxy layer are poor, and it is difficult to effectively enter the body of the crop and the target, resulting in a control effect Poor; in the natural environment of light, high temperature and dryness, the water in the liquid medicine is easy to evaporate, causing the medicine to only remain on the surface of the crops, and it is easy to photolyze and fall off from the crops after drying to fail; the droplets of conventional spraying The particle size is large, reaching 200-600 μm, which leads to the easy loss of the liquid sprayed on the surface of crops or targets; for a long time, the single and frequent use of pesticide varieties has made biological targets increasingly resistant to the pesticide itself, which is not conducive to harmful biological control

[0008] At present, the products of metaflumizone and indoxacarb ultra-low volume agent registered in my country have not been reported yet.
