Problems solved by technology

The use of prochloraz began in the 1970s. With the popularization and promotion of prochloraz in the field of fungicides in recent years, the problem of resistance has become more and more obvious. The amount of active ingredients used in the prevention and treatment of plant diseases has been increasing year by year, which gives crops and soil residues bring severe challenges, but in the field of plant sterilization, prochloraz still has an irreplaceable position

Embodiment 1

[0033] Embodiment 1, water dispersible granule (the total weight portion of preparation is 100 parts)

[0034] 30.0 parts by weight of prochloraz copper salt

[0035] Dimethomorph 3.0 parts by weight

[0036] 5.0 parts by weight of polyvinyl alcohol

[0037] Sodium lauryl sulfate 7.0 parts by weight

[0038] Lignosulfonate 11.0 parts by weight

[0039] Kaolin balance

[0040] The above-mentioned substances are uniformly mixed, ground, mixed with an appropriate amount of water, granulated, and dried to obtain the preparation. Wherein the prochloraz copper salt is N-propyl-N[2-(2,4,6-trichlorophenoxy)ethyl]-1-H-imidazole-1-carboxamide-copper chloride.

Embodiment 2

[0041] Embodiment 2, water dispersible granules (the total weight portion of preparation is 100 parts)

[0042] 8.0 parts by weight of prochloraz copper salt

[0043] Dimethomorph 67.0 parts by weight

[0044] 4.0 parts by weight of methylcellulose

[0045] Saponin 5.0 parts by weight

[0046] 2.0 parts by weight of polyvinyl alcohol

[0047] Kaolin balance

[0048] Grinding the above raw materials in water to obtain the required particle size, adjusting its concentration and viscosity to obtain a slurry for spraying, and then quantitatively sending the slurry into a drying tower for spray drying to obtain the product. Dilution of this concentrate with water gives dilute emulsified liquids of any concentration used in plant protection. Wherein the prochloraz copper salt is N-propyl-N-[2-(2,4,6-trichlorophenoxy)ethyl]-1-H-imidazole-1-carboxamide-copper chloride.

Embodiment 3

[0049] Embodiment 3, wettable powder (the total weight portion of preparation is 100 parts)

[0050] Prochloraz manganese salt 36.0 parts by weight

[0051] Dimethomorph 2.0 parts by weight

[0052] Alkyl polyoxyethyl ether sulfonate 5.0 parts by weight

[0053] Sodium lignosulfonate 4.0 parts by weight

[0054] Polyoxyethylene octylphenyl ether (8-9 moles of ethylene oxide) 3.0 parts by weight

[0055] Kaolin balance

[0056] The active ingredient is thoroughly mixed with the auxiliary agent, and it is thoroughly ground in a suitable mill, and the obtained wettable powder can be diluted with water to form a suspension of the required concentration. Wherein the prochloraz manganese salt is N-propyl-N-2-(2,4,6-trichlorophenoxy)ethyl]-1-H-imidazole-1-carboxamide-manganese chloride.

Abstract

The invention provides a bactericidal composition, which comprises active synergistic components of dimethomorph and prochloraz or agriculturally acceptable salt compounds thereof, wherein the weight ratio of the dimethomorph to the prochloraz amines is 1:0.01-50, and preferably 1:0.05-30. The bactericidal composition also comprises a carrier, a surfactant or an auxiliary agent. When the dimethomorph and the prochloraz amines are applied together, the bactericidal composition has obvious synergized action, and enlarges the bactericidal spectrum and reduces the applied times at the same time, and the dimethomorph and the prochloraz do not have cross resistance.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, in particular to a fungicidal composition with improved properties, in particular to an agriculturally acceptable salt compound comprising dimethomorph and prochloraz or prochloraz bactericidal composition. Background technique [0002] The application of chemical agents is the most effective means of controlling plant-damaging fungi. However, long-term continuous high-dose application of a single chemical fungicide is likely to cause problems such as drug residues, environmental pollution, and the development of drug-resistant fungi. Reasonable compounding or mixing of chemical fungicides has positive effects such as expanding the bactericidal spectrum, improving the control effect, prolonging the application period, reducing the dosage, reducing the injury, reducing the residue, and delaying the occurrence and development of fungal drug resistance and drug resistance.
