Problems solved by technology

Leaching has brought many problems to the use of herbicides: 1. Herbicides are leached downwards, resulting in poor weeding effect and easily causing residual groundwater pollution; 2. Through leaching, herbicides enter the soil layer of crop roots and cause Potentially selective herbicides damage crops; 3. Reverse leaching causes herbicides to move to the soil surface and be lost through volatilization
Due to their own physical and chemical properties, many pesticide active ingredients are difficult to process into environmentally friendly water-based preparations, and usually can only be processed into emulsifiable concentrates for sale. The extensive use of organic solvents has brought a great burden to the human living environment.
At the same time, the characteristics of organic solvents such as low flash point and low ignition point bring great inconvenience to storage and transportation.

Embodiment 1

[0035] 0.1% Zhongbuling Microcapsule Suspension Concentrate

[0036] Recipe: 0.1kg of Zhongbuling, 1kg of xylene, 0.1kg of hydrochloric acid, 1kg of Nongru castor oil polyoxyethylene ether, 0.1kg of urea-formaldehyde resin, and make up to 100kg of water.

[0037] Preparation process: In a reaction vessel with heat preservation and stirring, dissolve the active ingredient in a co-solvent, then add the co-agent, solvent and capsule wall material and stir evenly at high speed, then add the initiator, change to normal stirring, and gradually raise the temperature to 60 ℃, and then 6 hours under the condition of 60 ℃ heat preservation, the microcapsule suspending agent containing secbutaline is obtained; the process parameters are: the high-speed stirring speed is controlled at 1000 ~ 1500 rpm, and the normal stirring speed is controlled at 60 ~ 150 rpm.

[0038] According to the same preparation process as in Example 1, the following examples were prepared.

Embodiment 2

[0040] 1% Zhongbutaline Microcapsule Suspension Concentrate

[0041] Recipe: 1 kg of Zhongbuling, 1.5 kg of fatty acid methyl ester, 0.5 kg of triethanolamine, 2.5 kg of nonylphenol polyoxyethylene ether, 1 kg of polyisocyanate, and make up to 100 kg with water.

Embodiment 3

[0043] 5.5% Zhongbuling Microcapsule Suspension Concentrate

[0044] Formula: 5.5kg of butaline, 10kg of methanol, 0.5kg of triethylamine, 5kg of polysorbate-80, 2.5kg of gum arabic, and make up to 100kg with water.

Abstract

The invention discloses a micro-capsule suspending agent containing butralin. The micro-capsule suspending agent comprises butralin or a compound of butralin and a second active component, and a capsule wall material, an initiating agent, an additive, a cosolvent and a solvent, wherein the butralin or the compound of butralin and the second active component serves as an active ingredient, and the capsule wall material, the initiating agent, the additive, the cosolvent and the solvent serve as the balance of the micro-capsule suspending agent. The second active component is randomly one of alachlor, metolachlor, acetochlor, pretilachlor, propisochlor or butachlor and the like. The micro-capsule suspending agent can be used for controlling annual and perennial weeds in sugarcane fields or corn fields and has the advantages of being long in duration, high in work efficiency, synergetic in effect, safe and environment-friendly and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a microcapsule suspension containing secbutaline. Background technique [0002] Zhongbutaline, also known as dichloramine, nifediamine, bibutazone, and budding element, is an aniline herbicide with low toxicity to humans and animals. Zhongbutaline is a herbicide for selective pre-emergent soil treatment. Similar to trifluralin, after the drug enters the plant, it mainly inhibits the cell division of the meristematic tissue, thereby inhibiting the growth of weed sprouts and young roots. It can also be used as a plant growth regulator to control the growth of tobacco axillary buds. The currently registered dosage form is emulsifiable concentrate. [0003] Alachlor, metolachlor, acetochlor, pretilachlor, metolachlor, butachlor, etc. are amide herbicides, which are mainly used for soil treatment and control of grass weeds; currently on the market there are Various dosage forms ...
