The composition in the invention has the advantages of reducing dosage and cost. The composition specifically has better prevention effects on rice blast, leaf blast and spike blast.
Description
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, be specifically related to a kind of bactericidal composition and application thereof take fluazinam and Isoprothiolane as main active.
Background technology
Fluazinam (fluaziname) is a kind of efficient, wide spectrum, novel bactericide.Molecular formula is:
The mechanism of action and characteristics: sprout by resisting plane, mycelia breaks through, growth and plane formation and resist the course of infection in all stages.The fungicidal spectrum of fluazinam is very wide; its effect is better than the GPF (General Protection False bactericide. and it is to interlink spore genus; Botrytis; Phytophthora; Plasmopara; Sclerotinia and black property Pseudomonas germ are very effective; Botrytis cinerea to anti-benzimidazole type and dihydroxy carboxylic acid imide fungicides also has good effect; resistance of rainwater washing against; lasting period is long; have the effect of good control phytophagous mites concurrently, cross words section plant club root is also had good preventive effect, to by the microbial paddy rice damping off of head mold good preventive effect being arranged also.
Isoprothiolane (Isoprothiolane) is a kind of systemic fungicide.Molecular formula is:
Isoprothiolane has special efficacy to rice blast, and rice plant can suppress the germ intrusion after absorbing, and has especially suppressed phosphide N-methyltransferase, thereby suppresses pathogen growth, plays preventive and therapeutic action.This medicament also has the effect that suppresses brown plant-hopper, white-backed planthopper density concurrently.Control leaf pest, fringe pest.The long-pending rice blast of control also can be used for the large and small leaf spot of control of maize, stripe disease of barley, moire disease in cut phase and each dispenser of full heading time 1 time.
Present Isoprothiolane preparation mostly is greatly missible oil, wetting powder, has good bactericidal activity, can very fast degraded in environment, but this bactericide is unstable, and the processing formulation is less, consumes a large amount of organic solvents, can cause the pollution to environment.
Summary of the invention
The objective of the invention is for above-mentioned technical problem provide a kind of applied widely, cost is low, to the effective containing fluazinam of crop disease control and the bactericidal composition of Isoprothiolane.
A further object of the invention provides the purposes of above-mentioned bactericidal composition.
The objective of the invention is to realize by following measures:
The bactericidal composition of a kind of containing fluazinam and Isoprothiolane, the active component in the said composition is comprised of fluazinam and Isoprothiolane, and wherein, the mass ratio of fluazinam and Isoprothiolane is 30: 1～1: 20, is preferably 20: 1～1: 15.
In the described bactericidal composition, fluazinam and Isoprothiolane become any one formulation that allows on the agricultural chemicals with known additive compound.These known auxiliary agents can be dispersant commonly used, diffusant, defoamer, wetting agent, disintegrant etc.
The formulation of described bactericidal composition can be pulvis, wetting powder, emulsifiable concentrate or granule.
The application of described bactericidal composition in the bactericide of preparation control corps diseases, the particularly application in the bactericide of preparation control rice crop disease, the more preferably application in the bactericide of preparation control rice blast, leaf seasonal febrile diseases and tassel blast.
Beneficial effect of the present invention: what the present invention was used is to inhale strong selectivity heterocyclic nitrogen-group fungicide in the Isoprothiolane, and fluazinam is 2,6-dinitroaniline series bactericidal agent bactericide, and both mutually are mixed and can not produce low touching, but Synergistic reduces dosage, reduces cost.Control rice blast, leaf seasonal febrile diseases and tassel blast there is favorable effect.

Application Example 1: control rice blast test.
Test is processed: field trial is chosen in the plot of morbidity over the years and carries out, this test medicine consumption is established respectively three concentration for the treatment of according to the difference of each composition, but the contrast medicament is respectively commercially available agricultural chemicals 40% Isoprothiolane wet-milling and 50% fluazinam suspending agent SC and the test of blank clear water.
Each residential quarter 100m of test method
2, repeat 3 times; Investigation method behind the Investigation and Prevention, random searching 5 points in the test treatment region, 10 clumps every, investigate the disease number of sheets by 5 grade standards, calculate disease index and preventive effect.
Annotate: a is illustrated on α=0.05 level remarkable, and b is illustrated on α=0.05 level variant, and it is not remarkable that c is illustrated in α=0.05 level.
Field efficacy is the result show, fluazinam and Isoprothiolane composition have good control efficiency to rice blast, and control efficiency all is better than the single dose kind.
Application Example 2: rice blast indoor pharmacodynamic test
By a large amount of Seiving Tests, co-toxicity coefficient method analysis synergistic effect is between the two asked in utilization, finds in certain ratio range, and fluazinam and Isoprothiolane combination antagonism Pyricularia oryzae have obvious synergistic function, rather than simple summation action, specifically test as follows:
Test material: the sick leaf of rice blast that picks up from the field
Test method: choose the rice seedlings of 2～3 consistent leaf leaf periods of growing way, with the processing of spraying of the drug concentration for preparing, each medicament arranges 5 concentration, and each processing arranges three repetitions.Chemicals treatment connect bacterium after 24 hours, suspension is made in the germ extraction of picking up from the sick leaf of rice blast in field inoculated, and then placed in the greenhouse and cultivated.Check the blade disease index after 7 days, calculate the EC of each proportioning
50And co-toxicity coefficient (CTC).
Analytical method: when CTC＜100, then the composition performance is antagonism; When CTC=100, then composition performance is summation action, and when CTC＞100, then the composition performance is synergistic effect.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (the ATI)/theoretical toxicity index (TTI) of mixture] * 100
ATI=(standard medicament EC
50/ reagent agent EC
50) * 100
The percentage composition of B in the percentage composition of TTI=A medicament toxicity index * mixed concentrated A+B medicament toxicity index * mixture
Measurement result shows, fluazinam and Isoprothiolane have obvious synergistic effect in proportioning between 30: 1～1: 20, and especially between 20: 1～1: 15, synergistic effect is more remarkable.
Result of the test sees the following form:
The indoor biometrics result shows that fluazinam and Isoprothiolane complex preparation have than single component makes the preventive effect of making good use of, and both mix rear co-toxicity coefficient greater than 120, has obvious synergistic effect.Above-mentioned each test all refers to the consumption of active ingredient in each preparation with dosage.
