Description

Microbicide compositions

One, technical field

The present invention relates to microbicide compositions, refer more particularly to the composition and use thereof that contains methoxy-methyl acrylate compounds ZJ0712 and some interior absorption, contact and soil fungicides.

People know that the bactericide that is used for agricultural and gardening has many variety classeses.But the plant disease kind of preventing and kill off is also many, preventing and kill off in the agricultural production application of reality to various plant diseases, select comparatively ideal sterilization very difficult often, particularly the tillage method of current some crop changes, generally adopt greenhouse gardening as vegetables, melon, flowers etc., the condition of high temperature, high humidity very easily makes the generation of various diseases and popular, causes serious economy loss.As powdery mildew, downy mildew and anthracnose is the The main pathogenic fungi of damage to crops, and some leading products in the past such as triazole type and acid amide fungicides be because the generation of resistance, and consumption strengthens at double, is badly in need of new varieties and substitutes.Therefore, the novel germicide composition of should seek to have high activity, fungicidal spectrum is wide is considered in the new damage by disease and insect aspect that causes for the variation that is adapted to agriculture form.

Two, background technology

The present invention solves the problem of above-mentioned proposition, a kind of microbicide compositions that present inventors invented, (the exploitation code name: ZJ0712), the plant disease that this compound causes sac fungi, mastigomycetes and imperfect fungus etc. has excellent control efficiency to it is characterized in that containing in the composition a kind of methoxy-methyl acrylate compounds ZJ0712.Preparation example shown in this compound general formula is existing narration in Chinese invention patent (application number 03120882.7).The structure and the title of compound are as follows:

(E) 2-[2-(2,5-dimethyl phenoxy methyl)-phenyl]-3-methoxy-methyl acrylate (ZJ0712)

Three, summary of the invention

The object of the present invention is to provide a kind of composition that methoxy-methyl acrylate compounds and known other bactericide are mixed that contains of foregoing invention, its objective is to further improving bactericidal effect, expanding prevention object and delaying service life of compound (I).

At the methoxy-methyl acrylate compounds shown in the general formula (I) (to call compound (I) in the following text) with select more than one bactericide (to call compound (II) in the following text) among suction in some, protection and/or the soil bactericide for use.

Now find after deliberation, with compound (I) and some systemic fungicide, protective fungicide and soil fungicides be mixed use after, their bactericidal activity has tangible raising.

Cucumber variety: precious poplar No. 5

Controlling object: cucumber anthracnose

Test method: the sandy loam of in plastic basin, packing into, sowing cucumber seed (precious poplar No. 5), it is stand-by during one heart stage cucumber seedling to be cultured to two leaves in the greenhouse, to try material places and carries out the blade face medicine liquid spray on the crop sprayer and handle, inoculation cucumber anthracnose spore after 24 hours, postvaccinal examination material place phytotron to cultivate 7 days investigation incidences of disease.

Active substance	Concentration (ppm)	Preventive effect (%)
			Compound (I)	5	48.5
Carbendazim	100	27.4
			Mixture	5+100	91.6

Result of the test shows: it is 91.6% to the preventive effect of cucumber anthracnose that compound (I) 5ppm adds carbendazim 100ppm, apparently higher than the preventive effect of two single agent.
