Embodiment 1
[0047] A 0.5% mass percent ultra-low volume liquid formulation of tebufenpyrad includes the following ingredients:
[0048] Tebufenpyrad 0.5kg
[0049] N,N-Dimethylformamide 10.0 kg
[0050] Calcium dodecylbenzene sulfonate 1.5 kg
[0051] Castor oil polyoxyethylene ether 1.8kg
[0052] Second-line oil, make up to 100 kg
[0053] Preparation process: In a mixing kettle with a stirrer, first use part of the solvent to dissolve the active ingredient tebufenpyrad, then add the surfactant and the remaining solvent components, stir and mix well, and then get 1% pymetrozamide ultra-low Capacity liquid agent; process parameters are: the stirring speed is controlled at 90 rpm, the stirring time is 30 minutes, the temperature is normal temperature, and the pressure is normal pressure.
[0054] According to the same preparation process steps as in Example 1, the following examples can be prepared.

Abstract
The invention belongs to the field of pesticide, and mainly discloses an ultra-low volume liquid containing tebufenpyrad, wherein the ultra-low volume liquid is used for effective preventing and controlling of crop injurious insects via ultra-low volume spraying, low volume spraying or electrostatic spraying. The ultra-low volume liquid comprises an active component, a surfactant, and a solvent; the active component is tebufenpyrad, or a mixed material prepared by mixing tebufenpyrad with an active ingredient II. The ultra-low volume liquid is characterized in that: tebufenpyrad is taken as the active compound, and the balance is the surfactant and the solvent; 100% of the ultra-low volume liquid comprises 0.5 to 20% of tebufenpyrad by mass, 1 to 10wt% of the auxiliary agent, and the balance the solvent. Preparation of the ultra-low volume liquid is convenient, cost is low, drug effect is excellent, effect lasting period is long, synergistic effect is excellent, water consumption and environmental pollution are reduced, pesticide utilization ratio is increased, and pesticide application amount is reduced.
Description
technical field [0001] The invention relates to the field of pesticides, and mainly relates to an ultra-low-capacity liquid formulation containing tebufenfen which can effectively control crop pests through ultra-low-capacity spraying, low-capacity spraying or ultra-low-capacity electrostatic spraying. Background technique [0002] The ultra-low-capacity liquid agent screens out solvents with low volatility, high flash point, good solubility to the original drug, low phytotoxicity to crops, and low viscosity. When spraying, do not add water, but use ultra-low-capacity spray equipment, low Direct application with volumetric spray or ultra-low volume electrostatic spray. Since the ultra-low-volume spray does not contain highly volatile components in the droplets, its size and mass do not change significantly when it leaves the spray device and reaches the target, which reduces volatilization and drift. The mist droplets are fine and uniform, which meet the requirements of "...
