The invention belongs to the technical field of pesticide weeding, and discloses a weeding composition and application thereof.The weeding composition comprises an active component A and an active component B. The active component A is isoxafop-butyl, the active component B is any one of metamifop, cyhalofop-butyl, clodinafop-propargyl and pinoxaden, and the active component B is one of isoxafop-butyl, cyhalofop-butyl, clodinafop-propargyl and pinoxaden. The mass ratio of the active component A to the active component B is (1: 12)-(24: 1). The weeding composition disclosed by the invention is wide in weed control spectrum and can be used for comprehensively preventing and controlling various weeds in rice fields and wheat fields.

This invention relates to the field of pesticide technology, specifically to a herbicidal composition containing dichloroisoxane and clodinafop-propargyl and its application in controlling agricultural weeds, wherein the weight ratio of dichloroisoxane to clodinafop-propargyl in the composition is 1:0.03-32. The composition can significantly reduce herbicide damage to crops and has a synergistic effect on weeds, making it an ideal herbicide.

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 discloses a method for preparing a column aromatics-grafted cyclodextrin bicyclic chiral packing material and its application in the separation of chiral pesticides. This packing material separates brominated column aromatics from... β -Aminopropyl cyclodextrin is covalently grafted onto aminopropyl silica gel to form a bicyclic macrocyclic structure with multiple chiral recognition sites. The preparation process includes the catalytic condensation synthesis of brominated columnar aromatics and the bicyclic macrocyclic bonding reaction on the silica gel surface. This packing material exhibits high selectivity, multi-mode compatibility (can be used in both normal and reverse phases), and excellent stability. It is particularly suitable for the enantiomeric resolution of triazoles (propiconazole, triadimefon) and esters (clodinafop-propargyl), providing an efficient separation tool for the environmental behavior study and safety evaluation of chiral pesticides. This invention features a simple process and low cost, solving the problems of insufficient selectivity and narrow solvent applicability of existing chiral packing materials, and has the potential for industrial application.
