This invention belongs to the field of novel pesticides and provides a dispersible oil suspension for weed control in wheat fields, comprising a herbicidal active ingredient and adjuvants. The herbicidal active ingredient is diflubenzuron and triclopyralid butoxyethyl ester. The adjuvants consist of an emulsifying dispersant, a synergist, a thickener, an antifreeze agent, and a dispersion medium. The synergist is composed of lauryl alcohol and panthenol, with a weight ratio of lauryl alcohol to panthenol of 1:5-5:1, and its dosage is 5-10% of the total weight of the composition. By adding lauryl alcohol and panthenol as synergist, the moisturizing properties of the diflubenzuron and triclopyralid butoxyethyl ester solutions can be significantly improved, preventing the droplet volume from rapidly decreasing and facilitating the absorption of the pesticides, thereby achieving a synergistic effect.

This invention belongs to the field of agricultural chemistry and relates to a biphasic herbicidal dispersible oil suspension and its preparation method. The formulation consists of an oil phase A and a nano-aqueous phase B. Oil phase A contains a ternary compound herbicide of mesosulfuron-methyl, diflubenzuron, and clodinafop-propargyl, as well as safener A. Nano-aqueous phase B contains safener B, a hydrophilic co-solvent, and an aqueous phase adjuvant, ensuring that safener A is primarily distributed in the oil phase and safener B is primarily distributed in the aqueous phase, synergistically with a specific oil phase solvent, emulsifier, and polymer dispersion system. A pre-dispersion and sand milling process is used to obtain a biphasic fine-particle structure of oil droplets and nano-aqueous phase, maintaining good dilution and storage stability under high active ingredient loading conditions, while significantly reducing phytotoxicity to wheat and improving the control efficacy and duration of action against grasses and broadleaf weeds in wheat fields.

This invention relates to the field of pesticide technology, specifically to a herbicidal composition based on bentazon and its preparation method. The invention involves compounding bentazon, diflubenzuron, microspheres, functional adjuvants, defoamers, and other adjuvants to prepare a herbicidal composition with good herbicidal effect under low-temperature conditions. The microspheres are prepared from hydrophobically modified lignin, bentazon, sodium octenyl succinate starch, and maltodextrin. The hydrophobically modified lignin has good ultraviolet absorption and photothermal conversion capabilities, increasing the temperature of weed leaf surfaces and thus enhancing the physiological activity of weeds. This allows the herbicidal composition to be effectively absorbed by the weeds and exert its herbicidal effect. Sodium octenyl succinate starch and maltodextrin improve the chemical stability of bentazon, preventing its photodecomposition and demonstrating broad application prospects.
