Problems solved by technology

However, the dissolving effect of biodiesel is not as good as that of toluene and xylene when making bromthalonil EC, and the stability of the preparation is poor
The technicians of scientific research institutes and enterprises are constantly exploring and researching, hoping to find a more advanced method to manufacture bromothalonil emulsifiable concentrate. Although some progress has been made, there are still technical problems that have not been overcome in practical application.

Abstract

The invention relates to bromothalonil missible oil and a preparation method thereof, and belongs to the technical field of chemical engineering. The bromothalonil missible oil is composed of the following components in percentage by weight: 1-45% of bromothalonil raw reagent, 1-15% of ethanol, 10-30% of an emulsifier, 1-5% of a synergist and the balance of biodiesel. The preparation method comprises the following steps: fully stirring the ethanol, the biodiesel and the bromothalonil raw reagent in a stirrer until the raw reagent is completely dissolved, then adding the emulsifier and the synergist, feeding the mixture into a homogenizing machine, carrying out heating to 55 DEG C, carrying out stirring at a constant temperature for 45 minutes to obtain a uniform transparent oily liquid, standing the liquid at a high position for 4-6 hours, and carrying out filling to obtain the bromothalonil missible oil. The biodiesel is a renewable energy source and has good biodegradability; and solubility of the bromothalonil raw reagent in the biodiesel is increased by adjusting the ratio of the ethanol to the bromothalonil raw reagent, and the defect that stability of a preparation is poor isovercome by compatibility with the specific emulsifier; and the synergist is added, so that penetrability of the bromothalonil missible oil is enhanced, rainwater washing resistance is improved, themetabolism speed of the bromothalonil missible oil in prevention and treatment objects is delayed, and therefore, the biological prevention effect is improved. The bromothalonil missible oil preparedby using the formula and the method disclosed by the invention is low in toxicity, is environmentally friendly, and has good social and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bromothalonil emulsifiable concentrate and a preparation method thereof. Background technique [0002] Since the reform and opening up, my country's agricultural science and technology have developed rapidly, and farmers' demand for pesticides has also increased year by year. However, the increase in agricultural use has also caused prominent environmental problems. With the increasingly stringent environmental protection requirements, the development of environmentally friendly and low-toxic pesticides Pesticides are imminent. Bromothalonil is a broad-spectrum, high-efficiency, and low-toxic fungicide, which can inhibit and eradicate the growth of fungi, bacteria, and algae. It has a good preventive effect on crop diseases and has special effects on anthracnose. It is widely used in various economic crops such as fruit trees, grapes, vegetables, cotton, tobacco, and flowers...
