Embodiment 3

[0016] Formulation Example 3 : 60% propaneamidine·fluazinam water dispersible granules.

[0017] Propanamidine 5%, fluazinam 55%, wetting agent sodium lauryl sulfate 6%, dispersant lignosulfonate 4%, disintegrant urea 2%, binder polyethylene glycol 3%, Stabilizer soluble starch 3%, kaolin supplemented to 100%. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 60% propaneamidine·fluazinam water dispersible granules.

Embodiment 4

[0018] Formulation Example 4 : 50% propaneamidine·fluazinam water dispersible granule.

[0019] Propanamidine 3%, fluazinam 47%, wetting agent saponin powder 6%, dispersant sodium naphthalenesulfonate formaldehyde condensate 4%, disintegrant bentonite 2%, binder cyclodextrin 2%, stabilizer Soluble starch 3%, kaolin supplemented to 100%. The above formula is dry pulverized, granulated, dried and sieved according to the proportion to prepare 50% propaneamidine·fluazinam water dispersible granules.

[0020] Formulation Example 5 : 50% propaneamidine·fluazinam wettable powder.

[0021] Propanamidine 1%, fluazinam 49%, wetting agent pull-off powder 3%, dispersant lignosulfonate 6%, filler talc 15%, filler kaolin make up to 100%. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 50% propaneamidine·fluazinam wettable powder.

Embodiment 2

[0027] Bioassay Example 2 : Field efficacy test on lettuce sclerotinia.

[0028] This test was carried out in Futian Town, Boluo County, Huizhou City, Guangdong Province in March 2012. The spray was uniformly sprayed with 45 kg of water per mu, and the pesticide was applied once. The control effect after 7 days of spraying is shown in Table 2.

[0029] Table 2. Results of field efficacy tests on lettuce sclerotinia.

[0030]

[0031] As can be seen from Table 2, the bactericidal composition mixed with propaneamidine and fluazinam has a good control effect on lettuce sclerotinia. It was found in the test that the composition is safe to lettuce, and it can reach 7 days after the medicine. Ideal control effect.

Abstract

The invention discloses a bactericidal composition of propamidine and fluazinam. The bactericidal composition comprises commonly used auxiliary agents, propamidine and fluazinam. Mass part ratio of propamidine and fluazinam in the composition is 5:1-1:45, and preferably 3:1-1:25. When propamidine and fluazinam are compounded, a substantial synergetic effect is provided. Effective component dose of the compounded agent is substantially reduced than that of separate use. The composition provided by the invention is suitable to be used against crop gray mold caused by botrytis pathogen and crop stalk break casued by sclerotinia pathogen.

Description

technical field [0001] The fungicidal composition of the present invention uses propaneamidine and fluazinam as active ingredients, and is suitable for preventing and treating botrytis cinerea caused by botrytis and crop sclerotinia caused by sclerotinia. Background technique [0002] Propanamidine, English common name propamidine, 1,3-bis(4-amidinophenoxy) propane. Propanamidine is a broad-spectrum fungicide with protective and therapeutic effects, and has outstanding control effects on crop gray mold caused by botrytis and sclerotinia caused by sclerotinia. [0003] Fluazinam, English common name fluazinam, chemical name 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-dinitrate base-p-toluidine. Fluazinam is a protective fungicide. The current commercial dosage form is suspension concentrate, and the main method of use is to spray stems, leaves and soil. [0004] Sclerotinia sclerotiorum mainly causes sclerotinia of various crops; Botrytis cinerea ...
