The invention provides a preparation method of a quick-wetting carboxylic acid copolymer thickening agent, which comprises the following steps: adding an organic inert solvent containing at least 55wt% of a hydrocarbon solvent, 15wt%-20wt% of a monomer as well as an initiator, a dispersant and a cross-linking agent which are required by reaction into a reaction vessel, and performing reaction at 45-55DEG C for 30-60min; mixing an organic inert solvent containing at least 55wt% of an ester solvent, the rest of the monomer and the initiator, the dispersant and the cross-linking agent which are required by reaction, and adding the mixture into the reaction vessel within 3-6h and reacting under the same reaction temperature; and after all the reactant is dropwise added, raising the temperature to 55-75DEG C, adding the initiator again, performing heat preservation for 1-4h so that the monomer in the reaction system is reacted completely, ending the reaction, and discharging a product. The invention aims to provide the quick-wetting carboxylic acid copolymer thickening agent with quick wetting and dispersing properties and high bulk density, and meanwhile the invention further provides the preparation method of the quick-wetting carboxylic acid copolymer thickening agent.

The invention discloses wettability fungus powder capable of effectively degrading cypermethrin and 3-phenoxy benzoic acid and a preparation method. The wettability fungus powder comprises the raw materials of composite fungus liquid, diatomaceous earth, sodium lignin sulfonate, tween 80, skim milk powder and trehalose; and the composite fungus liquid consists of bacillus licheniformis B-1 fungus liquid and sphingomonas SC-1 fungus liquid. The method comprises the following steps: (1) the diatomaceous earth is added in the composite fungus liquid to obtain a carrier-fungus liquid mixture; the tween 80, the sodium lignin sulfonate, the skim milk powder and the trehalose are added in sterile water having the same volume with the composite fungus liquid to obtain auxiliary solution; and the auxiliary solution and the carrier-fungus liquid mixture are uniformly mixed to obtain fungicide mixed liquid; and (2) the fungicide mixed liquid obtained in the step (1) is dried by the following process parameters in sequence: a temperature from -46 to -48 DEG C is kept by 1.0-3.0 h; a temperature from -36 to -40 DEG C is kept by 1.0-3.0 h; a temperature from -26 to -30 DEG C is kept by 1.0-3.0 h; a temperature from -15 to -20 DEG C is kept by 1.0-3.0 h; a temperature from 0 to 4 DEG C is kept by 10-14 h; a temperature from 8 to 12 DEG C is kept by 1.0-3.0 h; a temperature from 30 to 40 DEG C is kept by 2.0-6.0 h; a temperature from 15 to 25 DEG C is kept by 20-24 h; and the wettability fungus powder is obtained.

The invention provides a quinclorac solid preparation. The quinclorac solid preparation comprises 30-70wt% of quinclorac, 2-10wt% of a synergist, 1-3wt% of a thickener, 2-8wt% of a wetting agent, 2-10wt% of a dispersant, and the balance of a filler. The quinclorac solid preparation is obtained through the steps of mixing all above components and crushing. The quinclorac solid preparation prepared in the invention has the advantages of short wetting time, high suspension rate, easy spray, uniform dispersion, difficult generation of local phytotoxicity in practical use; and the quinclorac solid preparation also has the advantages of small dosage, no phytotoxicity to crops, and environmental protection on the basis of meeting of crop weed injury control requirements.
