Flonicamid-containing ultralow volume liquid agent

Abstract

The invention discloses a flonicamid-containing ultralow volume liquid agent. The ultralow volume liquid agent consists of flonicamid or active ingredient compounded by using the flonicamid and an active ingredient II, and the balance of aids and solvent; and the active ingredient II is any one of ethiprole, etofenprox, tolfenpyrad, chlorantraniliprole, flubendiamide, ivermectin, abamectin and emamectin benzoate. The ultralow volume liquid agent can be used for preventing and controlling the pests such as rice planthopper, cnaphalocrocis medinalis, nilaparvata lugens, sogatella furcifera and the like, and has the advantages of low water consumption, high effect, long acting time, synergy and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an ultra-low volume liquid containing flonicamid. Background technique [0002] Flonicamid (flonicamid), molecular formula: C 9 h 6 f 3 N 3 O, chemical name: N-cyanomethyl-4-(trifluoromethyl) nicotinamide, a pyridine amide compound, its structural formula: [0003] [0004] Flunicamid acts by hindering the sucking action of pests. According to the analysis of electronic insect sucking behavior (EMIII), this agent can prevent the stylet tissues of sucking pests such as aphids from inserting into plant tissues and cause effects. The pests stop sucking soon after ingesting the potion, and finally die of starvation. It is effective against various piercing-sucking mouthparts pests and has good penetration. It can penetrate from roots to stems and leaves, but the penetration from leaves to stems and roots is relatively weak. Flunicamid has a unique mechanism of action and...

AI Technical Summary

Problems solved by technology

[0008] (1) The work efficiency of the conventional spraying method is low, and the work efficiency per capita is usually only 2 to 5 mu / day, which is difficult to meet the needs of large-scale planting; with the implementation of my country's land transfer policy, the land presents a trend of intensive management, and more and more There are many large agricultural growers, and the continuous planting area of ​​crops is increasing; and with the aging of my country's population and the emergence of labor shortages, labor is gradually becoming a scarce resource, labor costs continue to increase, and agricultural production costs continue to increase; agricultural production is seasonal Obviously, pests and diseases often require a lot of manpower to control in a short period of time

[0009] (2) The conventional spraying method needs a lot of water to control diseases and insect pests, usually the water consumption reaches 450-900L / hm2, but in many areas far away from water sources and arid and water-deficient areas, the conventional spraying method is difficult to implement or cannot achieve the ideal control effect

[0010] (3) The duration of the medicament used by the conventional spray method is short, because the dosage form of the medicament used by the conventional spray method is usually emulsifiable concentrate, water, wettable powder, suspending agent, water emulsion, etc., there are certain defects in use; on the one hand, due to Add 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 target , resulting in poor control effect; on the other hand, 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 the crops after drying Third, the droplet size of conventional spraying is relatively large, reaching 200-600 μm, or even larger, resulting in the easy loss of liquid medicine sprayed on the surface of crops or targets.

[0011] (4) For a long time, the single and frequent use of pesticide varieties has increased the resistance of biological targets to the pesticide itself, which is not conducive to the prevention and control of harmful organisms
