Embodiment 1

[0051] Embodiment 1 control wheat powdery mildew test

[0052]The potted two-leaf stage wheat seedlings of "Liaochun 15" were sprayed with an aqueous solution of active components (concentration of the active ingredients is as follows), and after 24 hours, the wheat powdery mildew fungus spores were shaken off on the wheat leaves. After culturing in the greenhouse, the degree of development of the fungus infection on the leaves was measured after 7 days.

[0053] See Table 1 and Table 2 for the activity data of each individual active component and the composition of the present invention for controlling wheat powdery mildew.

[0054] The results show that the observed potency values ​​of the composition are all greater than the calculated potency values, and the composition exhibits a synergistic effect within the test proportion range.

Abstract

The invention belongs to the field of agricultural fungicides, and particularly relates to a fungicidal composition and application thereof. The composition comprises two active components including an active component A and an active component B with the weight ratio being (1 to 99)-(99 to 1); the active component A is selected from a compound shown by a following general formula I; and the component B is selected from strobilurin fungicides. The fungicidal composition provided by the invention is particularly suitable for preventing and treating various plant pathogenic fungi diseases, suchas prevention and treating plant powdery mildew, venturia inaequalis, rust disease, scab, leaf mold, tarspot, sheath blight or seedling blight. (The general formula I is described in the following description.).

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to a fungicide composition containing pyrazole amide compounds and methoxyacrylate fungicides and an application thereof. Background technique [0002] Patent CN104649973A1 discloses a pyrazole amide compound and its use, wherein it is reported that the compound represented by the following general formula I has good activity against various fungal diseases. [0003] [0004] Among them, the compound with R1=CH3 and R2=n-Pr (compound 5 in CN104649973A1) has very good activity on various diseases. [0005] Methoxyacrylate fungicides are another type of new agricultural fungicides with great market vitality after triazole fungicides. They have protective, therapeutic and penetrating effects, and can control most oomycetes, ascomycetes and basidiomycetes. and fungal diseases such as fungi. [0006] In the practice of fungicide application, people often find that a kind of pe...
