Embodiment 1

[0058] Preparation of 1.0% chlorpyrifos ultra-low volume liquid

[0059]

[0060] Preparation process: In a mixing kettle with agitator, first use a part of the solvent to dissolve the active ingredient chlorpyrifos, then add the surfactant and the remaining solvent ingredients, stir and mix well to obtain 1% chlorpyrifos ultra-low volume liquid; The process parameters are as follows: the stirring speed is controlled to be 60-150 revolutions per minute, the stirring time is 15 to 60 minutes, the temperature is normal temperature, and the pressure is normal pressure.

[0061] According to the same preparation process steps as in Example 1, the following examples can be prepared.

Embodiment 2

[0063] Preparation of 30.0% chlorpyrifos ultra-low volume liquid

Abstract

The invention provides an ultra low volume concentrate containing chlorpyrifos. The concentrate is characterized in that chlorpyrifos or the compound of chlorpyrifos and an active ingredient II is taken as an active ingredient; an aid and a solvent are added till 100%; and the active ingredient II is any one of pymetrozine, clothianidin, spirotetramat, thiacloprid, buprofezin, tolfenpyrad, thiamethoxam, flubendiamide and chlorantraniliprole. The concentrate has the following advantages: the concentrate is convenient to process, has long acting time and high work efficiency, ensures that the targets do not have drug resistance easily, is low in environmental pollution, saves pesticides and water, improves the utilization rate of the pesticides and can be used for controlling various pests on rice, wheat, corn, vegetables, tobaccos, tea trees, fruit trees and sugarcanes through ultra low volume spraying, low volume spraying or ultra low volume electrostatic spraying.

Description

Technical field [0001] The invention relates to the field of pesticides, in particular to an ultra-low-volume liquid agent containing chlorpyrifos, which mainly realizes effective control of crop pests through ultra-low-volume spray, low-volume spray or ultra-low-volume electrostatic spray. Background technique [0002] At present, the main method for the prevention and control of pests that are easy to produce resistance in agriculture is to develop new ingredients that are not cross-resistant with existing varieties or to mix existing pesticide varieties. The former requires high development costs and long cycles. Moreover, the current development speed is far less than the speed of pest resistance. Therefore, it is the best choice to mix existing pesticide varieties with different mechanisms of action. If the ratio is reasonable, a significant synergistic effect can be produced, and the field control effect is significantly better than that of each single agent. Insecticides...
