Embodiment 1

[0050] Preparation of 8% Pymetrozine Ultra-Low Volume Liquid

[0051]

[0052] Preparation process: In a reaction vessel with electric stirring, the active ingredient pymetrozine is stirred and dissolved with a solvent according to the proportion of the formula, and then the auxiliary ingredients are added, and the ingredients are fully stirred and mixed evenly to obtain 8% pymetrozine ultra-low volume liquid agent; the process parameters are: the stirring speed is controlled at 60-150 rpm, the stirring time is 15-60 minutes, and the temperature is normal temperature.

[0053] Application method: The prepared ultra-low volume liquid agent is used for pest control by ultra-low volume spray, low-volume spray or ultra-low-volume electrostatic spray.

[0054] Following the same steps as in Example 1, the following examples can be prepared.

Abstract

The invention provides a pymetrozine-containing ultralow volume liquid agent, and belongs to the field of pesticides. The ultralow volume liquid agent consists of pymetrozine or active ingredient compounded by using the pymetrozine and an active ingredient II, and the balance of aids and solvent; and the active ingredient II is any one of bifenthrin, beta-cypermethrin, lambda-cyhalothrin, cyfluthrin, fenpropathrin, deltamethrin, etofenprox, triazamate, tolfenpyrad, chlorantraniliprole, flubendiamide, ethiprole, abamectin, emamectin benzoate, ivermectin, sec-butyl phenyl-N-methyl carbamate, buprofezin, hexaflumuron, flufenoxuron, chlorbenzuron, diafenthiuron, indoxacarb, 1,2-Dibenzoyl-1-tert-butylhydrazine and tebufenozide. The ultralow volume liquid agent is used for preventing and controlling multiple pests on paddy, wheat, corn, vegetables, tobacco, tea trees, fruit trees and sugarcane by ultralow volume spraying, low volume spraying or ultralow volume electrostatic spraying. The ultralow volume liquid agent 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 field of pesticides, in particular to an ultra-low volume liquid containing pymetrozine. Background technique [0002] At present, for the control of pests that are prone to resistance in agriculture, the main method is to develop new ingredients that have no cross-resistance with existing varieties or the compounding of existing pesticide varieties. The former is due to the high development cost and long cycle required. And the current development speed is far behind the speed of pest resistance. Therefore, it is the best choice to mix existing pesticide varieties with different action mechanisms. If the ratio is reasonable, it can produce a significant synergistic effect, making the field control effect significantly better than the effect of each single agent. Insecticides containing a single active ingredient often have certain defects in the control of agricultural pests. Continuous use for multiple times not only ma...
