Effective ingredients of the composition are isopyrazam (A) and imidazole bactericide (B), wherein B is selected from one of carbendazim, thiophanate methyl, benomyl and thiabendazole; and a mass ratio of A to B is 1:50-50:1. The composition has obvious synergistic effect and good safety, is suitable for controlling agricultural crop powdery mildew, particularly suitable for controlling vegetable, fruit tree and cereal crop powdery mildew.
Description
Technical field
The present invention relates to a kind of bactericidal composition, the application of especially a kind of bactericidal composition containing isopyrazam and control corps diseases thereof, belongs to technical field of pesticide.
Background technology
Powdery mildew is a kind of worldwide disease of extensive generation, is caused by the Erysiphaceae in fungi.In production, main employing chemical pesticide control powdery mildew, mainly relies on benzimidazole, hydroxy pyrimidine class, phenoxyquinolines class, triazole type and methoxy acrylic bactericide at present.These medicaments have created resistance in various degree because of Long-Time Service, and control efficiency reduces.In addition, triazole type medicament has inhibitory action when using dosage is large to the growth of crop, easily causes poisoning.Therefore effective pesticide control that research and development are new is needed badly.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, the following specific embodiment of the present invention is described, but the present invention is limited to absolutely not these examples.
Being undertaken composite by the pesticide active ingredient of different types of structure, is a kind of effective means solving the problem such as cost and resistance in agricultural chemicals single dose application process at present.After the pesticide active ingredient mixing of different types of structure, usually show three kinds of type of action, i.e. summation action, synergistic effect and antagonism, but be specially which kind of effect, unpredictable, only have and just can be known by lot of experiments.Compound synergic is well filled a prescription, and can improve actual control efficiency, and reduce Pesticide use dosage, contributing to the generation of delaying drug resistance, is the important means of integrated control.
The present composition has obvious synergistic function to Powdery Mildew etc., and is not only the simple addition of two kinds of pharmacy effects, is clear that very much this result can tested from following Toxicity Determination.
Assays Example: isopyrazam and imidazoles bactericide (carbendazim, thiophanate-methyl, benomyl and probenazole) the composite Toxicity Determination to cucumber powdery mildew's pathogen
Subjects: cucumber powdery mildew's pathogen (Sphaerothecafuliginea (Sch.) Poll) (pick up from the wild powdery mildew of cucumber bacterial classification in field, and through separating-purifying)
Test method: test, with reference to People's Republic of China (PRC) agricultural industry criteria NY/T1156.11-2008 " farm-chemical indoor determination test rule bactericide the 11st part: method cut out by control cucurbits powdery mildew test basin ", adopts basin method of cutting out to measure.
Sow susceptible cucumber variety, potted plant to grow to 2-4 leaf periods for subsequent use.The former medicine of isopyrazam and carbendazim (or thiophanate-methyl, benomyl, probenazole) former medicine dissolve with dimethyl formamide respectively, then dilute with 0.1% Tween-80 aqueous surfactant solution.Often process 3 basins, repeat for 4 times, 10ml liquid is evenly sprayed on blade face to all wetting, treats that liquid dries naturally for subsequent use.And establish the process only containing solvent and surfactant not containing active ingredient to make blank.24h after chemicals treatment, spray inoculation cucumber powdery mildew's pathogen spore suspension.The process for preparation of spore suspension is as follows: get and cover with Powdery Mildew cucumber leaves, is washed down by spore with the sterile water being added with a small amount of Tween-80 surfactant, and double gauze filters, and is modulated into 1x10 after microscopy
5the suspension of individual spore/milliliter.Inoculation is placed in thermostatic chamber, cultivates 10 days under temperature 20-24 DEG C of condition.When the sick leaf rate of blank reaches more than 80%, classification investigation manages incidence everywhere, calculates disease index and the control efficiency of each process.
Control efficiency is converted into probability value (y), and liquor strength (μ g/ml) converts logarithm value (x) to, calculates virulence equation and concentration EC in suppressing with method of least squares
50, toxicity index and the co-toxicity coefficient (CTC) of medicament is calculated according to the abundant method of Sun Yun.
Actual measurement toxicity index (ATI)=(standard agent EC
50/ reagent agent EC
50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100
When CTC≤80, then composition shows as antagonism, and as 80 < CTC < 120, then composition shows as summation action, and when CTC >=120, then composition shows as synergistic effect.Toxicity Determination is the results detailed in Table 1 to table 4.

As can be known from Table 1, when isopyrazam and carbendazim are between proportioning 1:50 ~ 50:1, co-toxicity coefficient is all more than 122, synergistic effect is shown as to cucumber powdery mildew's pathogen, especially, time between 1:10 ~ 5:1, co-toxicity coefficient is all more than 181, and synergistic effect is the most obvious.
Table 2 isopyrazam and the composite Toxicity Determination result to cucumber powdery mildew's pathogen of thiophanate-methyl
As can be known from Table 2, when isopyrazam and thiophanate-methyl are between proportioning 1:50 ~ 50:1, synergistic effect is shown as to cucumber powdery mildew's pathogen, co-toxicity coefficient is all more than 123, especially, time between 1:10 ~ 5:1, listed proportioning co-toxicity coefficient is all higher than 190, and synergistic effect clearly.
Table 3 isopyrazam and the composite Toxicity Determination result to cucumber powdery mildew's pathogen of benomyl
In table 3, result shows, when isopyrazam and benomyl are between proportioning 1:50 ~ 50:1, shows as synergistic effect to cucumber powdery mildew's pathogen, co-toxicity coefficient is all more than 125, especially, time between 1:10 ~ 5:1, listed proportioning co-toxicity coefficient is all higher than 192, and synergistic effect clearly.
Table 4 isopyrazam and the composite Toxicity Determination result to cucumber powdery mildew's pathogen of probenazole
In table 4, result shows, when isopyrazam and probenazole are between proportioning 1:50 ~ 50:1, shows as synergistic effect to cucumber powdery mildew's pathogen, co-toxicity coefficient is all more than 123, especially, time between 1:10 ~ 5:1, listed proportioning co-toxicity coefficient is all higher than 196, and synergistic effect clearly.

2, 200g/hm
2, 160g/hm
2, 150g/hm
2, 320g/hm
2, 300g/hm
2, 400g/hm
2and 360g/hm
2spraying, has good control efficiency to powdery mildew of strawberry.Control efficiency before second time dispenser is respectively: 82.98%, 88.40%, 86.37%, 80.34%, 90.43%, 87.75%, 78.55% and 81.62%, after second time dispenser, the control efficiency of 10 days is respectively 90.55%, 94.05%, 92.54%, 88.14%, 96.59%, 93.89%, 86.71% and 89.76%, is obviously better than contrast medicament 30% isopyrazam suspending agent by effective ingredient consumption 150g/hm
2preventive effect 68.02% and 79.68%, 50% carbendazol wettable powder is by effective ingredient consumption 450g/hm
2preventive effect 56.08% and 65.54%, 70% thiophanate-methyl wetting powder by effective ingredient consumption 350g/hm
2preventive effect 58.52% and 68.38%, 50% benomyl wetting powder by effective ingredient consumption 300g/hm
2preventive effect 54.95% and 61.40% and 40% probenazole wetting powder by effective ingredient consumption 420g/hm
2preventive effect 63.31% and 70.39%.Under corresponding test dose, reagent agent effectively can control the occurrence injury of powdery mildew of strawberry.Duration of test, reagent agent, to trial crops safety, occurs, to non-target organism safety without poisoning.
