Abstract
The invention relates to an acibenzolar-containing sterilizing composition, which comprises the following active ingredients: the acibenzolar (A) and a quinoline bactericide (B). The quinoline bactericide is selected from proquinazid or quinoxyfen; the mass ratio of A to B is 100:1-1:100; and the active ingredients account for 10 to 80 mass percent of the composition. The composition can be prepared into a suspension agent, a wettable powder, a water dispersible granule and other formulations. The sterilizing composition can be applied to farmlands, gardens and other places, and is used for preventing and controlling various plant diseases of crops such as grains, vegetables, flowers and the like, particularly powdery mildew.
Description
Technical field
The present invention relates to a kind of bactericidal composition, especially contain the bactericidal composition of Acibenzolar and a kind of quinolines bactericide, belong to the disinfectant use in agriculture field.
Background technology
Powdery mildew is the plant disease that is caused by the Erysiphaceae in the fungi (Erysiphacesae).Powdery mildew distributes extensively in the whole world, and the dicotyledon of causing harm is particularly general.The main powdery mildew of China has the cereal class powdery mildew that is caused by standing grain powdery mildew (Ery-siphe graminis); The powdery mildew of various plants such as melon, the beans that causes by Siberian cocklebur monofilament shell (Sphaerothecafuliginea), crudefiber crop; The grape powdery mildew that causes by grape snag shell (Uncinula necator); The powdery mildew of more than 80 kind of trees such as the mulberry that causes by hazel ball pin shell (Phyllactinia corylea), pears, persimmon, walnut, chestnut, lichee, papaya papaw; Powdery mildew of the Rosa flowers that cause by rose monofilament shell (Sphaerotheca pannosa) etc.
Blade produced yellow point when powdery mildew just took place, and then enlarged to develop into circle or oval scab, and the mould layer of adularescent powdery is given birth on the surface, is conidiophore and the conidium of germ, and back scab flavescence brown is the cleistothecium of germ.Mildew is early stage disperses separately, after be unified into a big mildew, even can cover full leaf, have a strong impact on photosynthesis, eubolism is interfered, cause early ageing, output incurs loss.
In the control of powdery mildew, mainly rely on medicaments such as benzimidazole, triazole type.These medicaments are because long-term use has produced pesticide resistance in various degree, and control efficiency reduces.A large amount of uses of medicament have simultaneously increased residue of pesticide, and the harm food security has increased the weight of environmental pollution.
Acibenzolar: English name acibenzolar, chemical name benzo (1,2,3) thiadiazoles-7-carbothioic acid-S-methyl esters, test code number CGA245704 is called for short BTH.Molecular formula C

Acibenzolar is a diazosulfide carboxylic acid esters plant disease-resistant activator.Acibenzolar makes plant obtain resistance through the defense response that activates crop self, thereby resists diseases such as powdery mildew, downy mildew, rust.Suitable crop has paddy rice, wheat, vegetables, banana, tobacco etc.
Pesticide active ingredient Combination application with Acibenzolar and other structure type; There is the composition of synergistic effect not only can obviously improve actual preventive effect; Reduce dosage and cost; Also help to avoid the generation and the suspension of pesticide resistance generation speed of germ resistance, can solve problems such as resistance and cost in the present agricultural chemicals list agent application process.
Summary of the invention
The object of the present invention is to provide that a kind of new resistance risk is little, cost is low, good drug efficacy, long bactericidal composition of lasting period.
The inventor is through a large amount of indoor biometrics and field control effectiveness tests, find that unexpectedly Acibenzolar and a kind of quinolines bactericide are mixed in certain proportion after, diseases such as powdery mildew are had significant synergistic effect.
Said quinolines bactericide is selected from the third oxygen quinoline or benzene oxygen quinoline.
The said third oxygen quinoline, English common name proquinazid, chemical name 6-iodo-2-propoxyl group-3-propyl group quinazoline-4 (3H)-ketone.Molecular formula C

Embodiment
Different pesticide active ingredients shows three kinds of type of action: summation action, synergistic effect and antagonism after mixing usually.But be specially which kind of effect, unpredictable, have only through a large amount of tests and just can know.Compound synergic is well filled a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, thereby delayed the drug-fast generation speed of germ widely, and be the important means of scientific prevention and cure disease.
The inventor has carried out a large amount of indoor bioassay test and field control effectiveness test; Find that Acibenzolar and the third oxygen quinoline or the combination of benzene oxygen quinoline afterwards have remarkable role in synergy to white powder germ etc., and be not only the simple addition (seeing biologicall test instance 1 for details) of two kinds of medicaments.
Biologicall test embodiment 1: the Acibenzolar and the third oxygen quinoline or the composite Toxicity Determination of benzene oxygen quinoline to wheat powdery mildew
Subjects: wheat powdery mildew (pick up from the field, indoor live body is cultivated and preserved)
Test method: with reference to " the agricultural industry criteria NY/T1156.4-2006 of the People's Republic of China (PRC) ".Choose the consistent potted plant 3-4 leaf phase wheat seedling of growth potential, 5 basins are selected in each processing for use, number subsequent use.Under 50PSI pressure, spray every basin 5mL with the Potter spray tower.Test is handled referring to table 1, table 2, table 3, and each medicament is provided with 5 concentration gradients.Inoculum density is 3 * 10 behind the 24h
5The wheat powdery mildew conidial suspension of individual spore/mL.With the wheat seedling that sprays the equivalent clear water is blank.After the inoculation wheat seedling being put into the greenhouse cultivates.Behind the 10d,, and calculate wheat powdery mildew state of an illness grade scale according to the morbidity grade scale complete stool investigation disease index of wheat powdery mildew:
0 grade: blade does not have scab;
1 grade: lesion area accounts for the area of whole blade below 5%;
3 grades: lesion area account for whole blade area 6%～10%;
5 grades: lesion area accounts for 11%～25% of whole blade area;
7 grades: lesion area accounts for 25%～50% of whole blade area;
9 grades: lesion area accounts for more than 50% of whole blade area.
The expection effectiveness of mixture of active principles (be theoretical control efficiency, %) use Colby formula is confirmed and is compared with observed effectiveness:
Colby formula: E=X+Y-X*Y/100
