Description
Technical field
Field of pesticide preparation of the present invention, specifically a kind of Bactericidal composite containing ZEN 90160 and bromothalonil
Thing, for preventing and treating watermelon anthrax, banana freckle.
Background technology
The resistance problem of agricultural disease is a global problem, is always the emphasis class of agricultural science and technology worker concern
Topic.With the continuity year in year out of disease chemical prevention, the increase of Pesticide use amount and not scientifical use agricultural chemicals, germ
Resistance getting worse, the germ species for producing resistance are on the increase.Meanwhile the use agricultural chemicals of high intensity, cause agricultural product agricultural chemicals
Exceeded, environmental pollution and the increase of peasant's drug cost etc. are remained, is unfavorable for agricultural sustainable development.Therefore, research and development efficiently,
Low toxicity, the bactericide agricultural chemicals of environmental protection have positive effect to agricultural sustainable development.
ZEN 90160 is controlling object wide spectrum, systemic fungicide, be mainly used in preventing and treating wheat class foliage disease such as leaf blight,
Leaf rust, glume blight, brown spot, powdery mildew, melon disease such as anthracnose, blight dis-ease, sigatoka, scab etc..
Bromothalonil is a kind of wide-spectrum bactericide, there is preferably treatment and eradicant action to various bacteria, fungal disease, right
Anthracnose germ special efficacy.
The mixture of different pesticide species, it is the common methods for preventing and treating agricultural pest.Screened, filtered out by formulation of pesticide
Rational formula, can effectively improve actual prevention effect, reduce dosage, reduce cost, delay the drug-fast generation of pest and disease damage,
It is the important means that agricultural synthesis is administered.The present inventor has made intensive studies to the recipe determination of ZEN 90160 and bromothalonil,
Have substantially to watermelon anthrax, banana freckle in certain mixed ratio scope it was found that ZEN 90160 and bromothalonil carry out mixture
Synergistic effect, after further study, complete the present invention.
The composition and application of ZEN 90160 and bromothalonil there is no report at present.
The content of the invention
The purpose of the present invention is to be compounded the different ZEN 90160 of the mechanism of action and bromothalonil, there is provided it is a kind of efficiently,

Illustrate, but the present invention is only limitted to absolutely not these embodiments.As described below is only the preferable embodiment of the present invention, is used only for
The description present invention, it is impossible to be interpreted as limiting the scope of the present invention.It is it should be pointed out that all in the spirit and principles in the present invention
Within all any modification, equivalent and improvement done etc., should be included in the scope of the protection.Therefore, this hair
The protection domain of bright patent should be determined by the appended claims.
Content described in embodiment is weight percentage.
Preparation method embodiment 1：30% ZEN 90160 bromothalonil wettable powder.
It is well mixed entering after above-mentioned material in proportion coarse crushing in blender, then 30% is made after air-flow crushing
ZEN 90160 bromothalonil wettable powder.
Preparation method embodiment 2：20% ZEN 90160 bromothalonil water dispersible granule.
By above-mentioned formula, dry pulverization process, granulation, drying, screening preparation system produce 20% ZEN 90160 bromothalonil in proportion
Water dispersible granules.
Preparation method embodiment 3：20% ZEN 90160 bromothalonil suspending agent.
Above-mentioned material is crushed in advance in proportion, adds in sand mill and grinds, system is allocated after high shear mixing
Obtain 20% ZEN 90160 bromothalonil suspending agent.
Assays Example 1：Indoor bioassay is tested.
Standard method NY/T1156.2-2006 is surveyed with reference to raw, using pastille culture medium method：Take each single dose and mixture series dense
The decoction 6mL of degree, add in the PDA culture medium for the 54mL for being cooled to 45 DEG C, the pastille culture medium of final concentration is put down required for being made
Plate.Then 6mm diameter mycelia blocks are produced from the object bacteria colony edge of culture 7 days, moved in each serial pastille culture medium, mycelia
Down, each 4 repetitions of processing.It is disposed, is placed in 25 ± 1 DEG C of constant temperature biochemical cultivation case and cultivates.
Culture medium flat plate is taken out after 3 days, each processing colony diameter is measured with crossing method, calculates the mycelia life of each processing
Long inhibiting rate.It is independent variable x according to the logarithm value of drug concentration (mg/L), using the probit value of corrected mortality as dependent variable y, point
Virulence regression equation is not established, the EC of single dose and each proportioning mixture is calculated using DPS softwares50And its mixture co-toxicity coefficient.Altogether
Malicious coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficients
(CTC) ＜ 120 shows as summation action.Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100。
Theoretical toxicity index (TTI)=(A percentage composition in A toxicity index × mixture)+(the hundred of B in B toxicity index × mixture
Divide content).Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100
The indoor joint toxicity measuring result of table 1, ZEN 90160 and bromothalonil to watermelon anthrax bacteria
