Description

The Fungicidal mixture of control pathogenic agents of rice
The present invention relates to prevent and treat the Fungicidal mixture of pathogenic agents of rice, this mixture comprises following compound as active component with cooperative effective quantity:
1) triazolopyrimidine derivative of formula I:
Figure C20048002843300041
With
2) the oxime bacterium ester (trifloxystrobin) of formula II:
Figure C20048002843300042
In addition, the invention still further relates to the method for the mixture control pathogenic agents of rice that uses Compound I and Compound I I, Compound I and the Compound I I purposes in such mixture of preparation, and the composition that comprises this mixture.
Compound I, i.e. 5-chloro-7-(4-methyl piperidine-1-yl)-6-(2,4, the 6-trifluorophenyl)-[1,2,4] triazols [1,5-a] pyrimidine, its preparation and known by document (WO98/46607) to the effect of harmful fungoid.
Compound I I, i.e. (E)-methoxyl group imido grpup-{ (E)-α-[1-(α, α, α-trifluoromethyl-m-phenyl) ethyleneimino oxygen base]-o-tolyl } methyl acetate, also (EP-A 460575 by document in the effect of its preparation and opposing harmful fungoid thereof; Common name: oxime bacterium ester) known.Oxime bacterium ester is sold on market, mainly as the fungicide of the opposing that is used for the cereal class by Ascomycetes (Ascomycetes) or fungus-caused mildew of Basidiomycetes (Basidiomycetes) and rust.
The mixture of triazolopyrimidine derivative and oxime bacterium ester (CGA-279202) is known by EP-A 988790 with general fashion.Compound I be included in the generality of this publication open in, but clearly do not illustrated.Therefore, the combination of Compound I and oxime bacterium ester is new.
Be described as various diseases to cereal class, fruits and vegetables by EP-A 988790 known Synergistic mixtures, for example mildew on wheat and the barley or the gray mold on the apple have Fungicidally active.
Because the special cultivation condition of rice plants, the requirement that rice need be satisfied with fungicide significantly is different from the required satisfied requirement of the fungicide that uses in cereal class or the fruit growing.Difference is being arranged: except the foliage applying method of using under many circumstances, in modern rice class plantation, fungicide is directly put on the soil on the application process in the sowing process or in the later short time of sowing.Fungicide is absorbed in the plant by root, and is transported to plant part to be protected in the juice of plant.On the contrary, in cereal class or fruit growing, fungicide is applied on leaf or the fruit usually; Therefore, the systemic action of reactive compound is obviously not too important in these crops.
In addition, pathogenic agents of rice is different from the pathogene in cereal class or the fruit usually.(Cochliobolus miyabeanus) is with Bamboo grass wood photovoltaicing leather bacteria (Corticium sasakii, synonym: be disease pathogene the most general in the rice plants Rhizoctonia solani Kuhn (Rhizoctonia solani)) for Pyricularia oryzae (Pyricularia oryzae), palace portion cochliobolus.Rhizoctonia solani Kuhn is the unique pathogene with agriculture importance from Agaricomycetidae subclass.Different with other fungies of great majority, this fungi is not by spore but is infected and encroached on plant by mycelium.
For this reason, the discovery of the Fungicidally active in relevant cereal class or the fruit cultivation can not be used for rice class crop.
The agricultural practice experience has shown in the control of harmful fungoid and to repeat and use the quick selection that the single-activity compound causes fungal bacterial strain in many cases separately that this bacterial strain has produced natural or adaptive pesticide resistance to described reactive compound.Thereby can not effectively prevent and treat these fungies with described reactive compound again.
In order to reduce the selection danger of pesticide resistance fungal bacterial strain, adopt the mixture of different activities compound to prevent and treat harmful fungoid now usually.By the reactive compound that combination has the different mechanisms of action, can guarantee the successful control of long period.
In order pathogenic agents of rice to be carried out effective pesticide resistance management and effectively to prevent and treat, the purpose of this invention is to provide the mixture that has improved anti-harmful fungoid effect under the total amount minimizing of using at reactive compound with the little rate of application of trying one's best.
We find that this purpose realizes by the mixture of beginning definition.In addition, we find to compare with using the issuable effect of unification compound, simultaneously, i.e. and associating or administered compound I and Compound I I or administered compound I and Compound I I can prevent and treat pathogenic agents of rice better successively respectively.
When this mixture of preparation, preferably adopt pure reactive compound I and II, as required can be to other reactive compound that wherein adds opposing harmful fungoid or other insect such as insect, spider or nematode, perhaps weeding or growth regulating-activity compound or fertilizer.

Application Example 1-is to the protection activity of the microbial rice blast of rice blast
With aqueous suspension cultivar is sprayed to the drip point for the leaf of the potted plant rice sprouts of " Tai-Nong67 " with following activity compound concentration.Second day, with the spore aqueous suspension inoculation plant of Pyricularia oryzae.Then test plants is placed 22-24 ℃ with the climatic chamber of the relative atmospheric humidity of 95-99% 6 days.Naked eyes are measured the development degree that infects on the leaf then.
Estimate by determining the percentage that infects plant.These percentages are changed into effectiveness.
Use the Abbot formula to render a service (E) by following calculating:
E=(1-α/β)·100
α corresponding to the fungal infection percentage of handling plant and
β is corresponding to the fungal infection percentage of (contrast) plant of being untreated.
Effectiveness is that 0 expression is handled the level that infects of plant corresponding to untreated check plant; Effectiveness is that 100 expression processing plants are infected.
Use the Colby formula to determine the expection effectiveness (R.S.Colby, Weeds (weeds), 15, the 20-22 pages or leaves, 1967) of the mixture of reactive compound, and compare with the effectiveness of observing.
Colby formula: E=x+y-xy/100
Expection when the E working concentration is the mixture of the reactive compound A of a and b and B is renderd a service, represents with % with respect to untreated control,
Effectiveness when the x working concentration is the reactive compound A of a is represented with the % with respect to untreated control,
Effectiveness when the y working concentration is the reactive compound B of b is represented with the % with respect to untreated control.
