The ultralow-volume liquid disclosed by the invention is convenient to process, long in lasting period and high in work efficiency; a target is unlikely to generate resistance to insecticide; environmental pollution is low; the insecticide and water are saved; the utilization rate of the insecticide is increased; by adopting ultralow-volume spraying, low-volume spraying or ultralow-volume electrostatic spraying, various insects of rice, wheat, corn, vegetables, tobaccos, tea trees, fruit trees and sugarcane are prevented and treated.

The invention discloses a mixed insecticide of tea saponin and a carbamate insecticide. The mixed pesticide preparation comprises the components in percent by weight: 0.01% to 80% of tea saponin, 0.5% to 80% of carbamate insecticide and the balance of assistant agent. The mixed pesticide preparation can be prepared into missible oil, wettable powder, microemulsion, a suspension agent, a suspension emulsion or a water emulsion. The carbamate insecticide and the tea saponin are selected for mixing, therefore, the mixed insecticide has obvious synergy; compared with a single agent, insecticidal activity is obviously enhanced; and the mixed insecticide has multiple treating effects on various pests, thereby reducing manpower and material utilization in the processes of controlling the pests and enhancing production benefits. At the same time, on the premise of ensuring medical effects, the invention remarkably reduces the cost. The mixed insecticide has various preparations, simple preparation method and high popularization value.

The invention discloses a mandrel which is used in electrothermal liquid preparation. The mandrel is loaded with biological activity components which can volatile when being heated; the biological activity components comprise one or some of the pyrethroid insecticides, organic phosphorus insecticides and carbamate insecticides. By means of the mandrel of the above scheme, the loaded biological activity components can be quickly volatilized when heated at the first time; therefore, the mandrel can solve the problem that existing electrothermal liquid preparations have small volatilization quantity in the first hours of heating at the first time so that the biological pesticide effect is poor; thus, newly bought electrothermal liquid preparation can quickly come into play without the need of preheating in advance, which shortens the time for the electrothermal liquid preparation coming into play and therefore the electrothermal liquid preparation is more convenient for use. The invention also discloses a preparation method of the mandrel and an electrothermal liquid preparation.

The invention discloses an insecticidal composition having a synergism. The invention provides the sterilization composition. The composition comprises two effective components A and B, wherein the active component A is methoxyfenozide, the active component B is selected from one of carbamate insecticides comprising carbosulfan, benfuracarb and fenobucarb, and the weight ratio of the two components is 1:30 to 30:1. The invention also provides a preparation method and an application of the composition. Test results show that the composition provided by the invention has obvious synergism, can reduce the use amount, and reduces the prevention and control cost. The insecticidal composition can effectively prevent and control various pests of paddy rice, vegetables and other crops. Through compounding of the insecticides having different action mechanisms and action modes, the composition effectively reduces the application amount of each single agent, and has quite good effects in expanding the insecticidal spectrum, delaying the pest drug resistance and improving the prevention and control effect and other aspects.

The invention belongs to the field of insecticides, and relates to an insecticidal and acaricidal composition containing a carbamate insecticide. The composition contains an active component A and an active component B, a weight part ratio of the component A to the component B is 1:99-99:1, the active component A is a compound I represented by a structural formula shown in the invention, and the active component B is selected from carbamate insecticides. The composition has the advantages of obvious synergy and resistance delaying, and can be used for controlling various insects.

A system that can assess red blood cell AChE activity to provide warning of exposure and possibly inform treatment with medical countermeasures is disclosed. A portable, ideally hand-held, in vitro diagnostic point of care system capable of electrochemically-based detection of red blood cell acetylcholinesterase (AChE) activity from an undiluted whole blood sample provides a real-time pre-symptomatic warning of exposure to organophosphorus nerve agent or other poison, such as a pesticide, which informs treatment with medical countermeasures. One preferred version of the invention provides a system that uses highly stable test strips and a lightweight, low power hand-held potentiostat detector. The disclosed invention provides a real-time quantitative assessment of cholinesterase (ChE) enzymatic activity directly from a small whole blood sample for indication of exposure to ChE inhibiting substances (i.e., chemical warfare nerve agents or carbamate pesticides), thereby allowing immediate assessment of a blood sample in the field during the pre-symptomatic window.

The invention belongs to the technical field of pesticides, and particularly relates to an ultra-low volume liquid containing cycloxaprid and a carbamate pesticide.
