Embodiment 1

[0021] Embodiment 1 Preparation of an aqueous agent containing polyhexamethylene biguanide hydrochloride and octoprodil

[0022] Components include: polyhexamethylene biguanide hydrochloride 1%, octocalid 5%, propoxyquine 5%, methanol 5%, OP-103%, water supplement 100%.

[0023] The preparation process is as follows: Weigh the materials according to the above mass percentage, thoroughly dissolve polyhexamethylene biguanide hydrochloride and octoprodil with methanol and water, and mix well with OP-10 to obtain 6% polyhexamethylene biguanide Cyclostatin hydrochloride aqueous solution.

Embodiment 2

[0024] Example 2 Preparation of wettable powder containing polyhexamethylene biguanide hydrochloride and octoprodil

[0025] Components include: polyhexamethylene biguanide hydrochloride 2%, octoprodil 4%, alkyl naphthalene sulfonate formaldehyde condensate 4%, sodium isopropyl naphthalene sulfonate 3%, white carbon black 6%, Sorbic acid 3%, kaolin topping 100%.

[0026] The preparation process is as follows: Weigh the materials according to the above mass percentage, mix polyhexamethylene biguanide hydrochloride, octoprodil, alkyl naphthalene sulfonate formaldehyde condensate, sodium isopropyl naphthalene sulfonate, white carbon black, sorbic acid Acid and kaolin were put into a mixer and mixed evenly, and jet-milled to below 800 mesh to obtain 6% polyhexamethylene biguanide hydrochloride octocalid wettable powder.

Embodiment 3

[0027] Example 3 Preparation of water-dispersible granules containing polyhexamethylene biguanide hydrochloride and octoprobin

[0028] Components include: polyhexamethylene biguanide hydrochloride 3%, octoprodil 3%, aryl sulfonate 2%, phosphate ester 3%, ammonium sulfate 15%, citric acid 3%, cornstarch 20%, kaolin 100%.

[0029] Preparation method: Weigh the material according to the above mass percentage, mix polyhexamethylene biguanide hydrochloride, octocalid, aryl sulfonate, phosphate ester, ammonium sulfate, citric acid, corn starch, kaolin in a mixer Evenly, carry out jet crushing, then add to a fluidized bed granulator for boiling granulation, after drying, sieving, sampling and analysis to obtain 6% polyhexamethylene biguanide hydrochloride octocalid water-dispersible granules.

Specifically, the bactericidal composition contains the effective components: polyhexamethylene biguanide hydrochloride and Xinjunan, wherein the mass ratio is 1: 40-40: 1, and the composition can be prepared into water aqua, wettable powder, water dispersible granules, soluble powder and soluble granules. The bactericidal composition has a good effect of controlling rice blast and stripe disease.

Description

technical field [0001] The invention relates to the field of agricultural disease prevention and control, in particular to a fungicidal composition containing polyhexamethylene biguanide hydrochloride and octoprodil and application thereof. Background technique [0002] Polyhexamethylene guaidine hydrochloride (Polyhexamethylene guaidine hydrochloride) has a broad-spectrum bactericidal; Polyhexamethylene guaidine hydrochloride can produce ionization in aqueous solution, and its hydrophilic part contains strong positive charge, and the adsorption is usually All kinds of negatively charged bacteria and viruses enter the cell membrane, inhibit the synthesis of liposomes in the membrane, and cause cell apoptosis. Polyhexamethylene biguanide hydrochloride is easily soluble in water, has the characteristics of colorless, odorless, non-toxic, non-corrosive, non-flammable, non-explosive, safe to use, and can be used at room temperature; polyhexamethylene biguanide Hydrochloride can...
