Improved horticultural herbicide and preparation method thereof

Abstract

The invention discloses an improved horticultural herbicide and a preparation method thereof. The improved horticultural herbicide is prepared from the following raw materials in percentage by mass: 1to 10 percent of oxyfluorfen, 10 to 30 percent of acetochlor, 1 to 5 percent of an antifreeze agent, 2 to 20 percent of an emulsifier, 10 to 30 percent of a solvent, 0.1 to 0.5 percent of a defoamingagent and the balance of water. The preparation method of the improved horticultural herbicide comprises the following steps: weighing all components according to the mixture ratio, mixing the oxyfluorfen, the acetochlor and the emulsifier with the solvent and stirring to form a uniform oil phase; mixing the water, the antifreeze agent and the defoaming agent and stirring to form an uniform aqueous phase; starting a high speed shearing machine, and pouring the oil phase into the aqueous phase under the condition of high speed shearing to obtain homogeneous O / W type emulsion with good dispersibility and particle size of microns, namely the improved horticultural herbicide. According to the horticultural herbicide disclosed by the invention, the oxyfluorfen is mixed with the acetochlor foruse, so that a weed control spectrum of a single agent is expanded; the improved horticultural herbicide has the advantages that all kinds of weeds in gardening can be prevented and controlled, time and labor are both saved, the use cost is reduced and environment friendliness is achieved.

Description

technical field [0001] The invention belongs to the field of horticultural chemicals, and in particular relates to an improved horticultural herbicide and a preparation method thereof. Background technique [0002] With the construction of modern cities, horticultural vegetation covers more and more land, especially in newly built residential quarters, where the planting of green vegetation is more abundant. Accelerating the construction of greening can obviously purify the air in the city. The weeds in the horticultural green vegetation grow rapidly, not only competing with the green vegetation for nutrients and water, but also the intermediate hosts of various diseases and insect pests. If the control is not timely, it will spread and affect the growth of green vegetation. [0003] Chemical weed control is one of the main means of weed control in horticulture, and the use of a single compound herbicide can easily lead to weed resistance. At the same time, when weeds occur...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that when a single pesticide is used alone, it is easy to produce drug resistance to horticultural vegetation weeds and cannot control various weeds in horticulture at one time, and the actual control effect is relatively poor. Efficient, broad-spectrum, economical, safe, and herbicidal composition that is beneficial to the comprehensive management of weeds
