Problems solved by technology

[0002] Most of the conventional preparations of profenofos are emulsifiable concentrates, and the droplet diameter (200-300 μm) of conventional spraying mainly uses water as the carrier, which has poor adhesion and is not resistant to rain washing, which affects the efficacy of the medicine. In addition, aromatic hydrocarbons are usually used as solvents. Certain toxicity, easy to pollute the environment

Embodiment 1

[0038] Preparation of 40% profenofos ultra-low volume liquid

[0039]

[0040] Preparation steps:

[0041] (1) Put the above components into the preparation kettle according to the proportioning ratio;

[0042] (2) Open the preparation kettle, the rotating speed is 90rpm, stir for 2h, and carry out preliminary stirring and mixing under normal temperature and pressure;

[0043] (3) Turn on the high-shear pump, carry out shearing and mixing under normal temperature and pressure, the rotating speed is 1500rpm, and mix for 4 hours, so that the system is fully sheared, dispersed, milked and homogeneous, and becomes a stable homogeneous liquid, and finally packed , that is, 40% profenofos ultra-low volume liquid.

Abstract

The invention discloses an ultralow volume liquid agent of profenofos and a preparation method of the ultralow volume liquid agent. According to the liquid agent, the profenofos is selected as an active component, and additives, such as glycol ether, methyl oleate, epoxy soybean oil, an emulsifying agent and the like are added. The preparation method of the ultralow volume liquid agent comprises the following steps of preliminarily stirring and mixing the raw materials according to a compounding ratio, and starting a high-shear pump for shearing and mixing so that a system can sufficiently perform shearing, dispersion, milking and homogenizing, and stable homogeneous liquid is obtained. The ultralow volume liquid agent disclosed by the invention is convenient to process, low in cost, good in drug effects, long in persistent effect and high in coordination and synergism, and water resources can be saved; and environmental pollution can be reduced, the utilization rate of pesticides can be increased, and the application quantity of the pesticides can be reduced. Compared with a preparation method of a conventional ultralow volume liquid agent, the preparation method disclosed by the invention has the advantages that the ultralow volume liquid agent prepared by the preparation method is stabler in properties and longer in persistent effect periods.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an ultra-low volume liquid formulation of pesticides. Background technique [0002] Most of the conventional preparations of profenofos are emulsifiable concentrates. The diameter of conventional spray droplets (200-300 μm) mainly uses water as the carrier. Certain toxicity, easy to pollute the environment. [0003] Compared with the prior art, the present invention has the following advantages after making profenofos into an ultra-low volume liquid: [0004] (1) Less spraying volume and high work efficiency: The amount of liquid medicine sprayed per unit area by ultra-low volume spraying is usually 900-4950mL / hm 2 , only one percent of the conventional spray. Generally, drift cumulative spraying (such as aircraft spraying) is used, which is dozens of times more efficient than conventional targeted spraying. [0005] (2) High concentration: The liquid concentration of ultra-low volu...
