Abstract
The invention discloses application of a fungicidal composition containing prochloraz. The fungicidal composition containing prochloraz can be applied to control over scab of wheat or spike-stalk brown spot of grape. The fungicidal composition contains effective components, and the effective components include prochloraz and prothioconazole in the mass ratio of (1-6):(6-1). For control over scab of wheat and spike-stalk brown spot of grape, an improvement based on the traditional fungicide prochloraz is performed by compounding the traditional fungicide pesticide prochloraz and prothioconazole, and the effects of improving the control effect and retarding resistance are achieved. The control effect of the fungicidal composition with certain matching on scab of wheat and spike-stalk brown spot of grape is far better than that of single components used before compounding; besides, compared with prochloraz, the disease control effect is greatly improved, a remarkable synergistic effect is achieved, and the fungicidal composition plays a significant enlightening role in development of low-toxicity economical pesticides; meanwhile, the problem of pesticide resistance caused when prochloraz is used alone is solved.

Gained Prochloraz, prothioconazoles and its built agent are shown in Table to fusarium graminearum biological activity (virulence) measurement result
1.
1 Prochloraz of table, prothioconazoles and its built agent are to fusarium graminearum biological activity (virulence) measurement result
As shown in table 1, through indoor biological determination of activity and formulation screening test, Prochloraz is with prothioconazoles single dose to Semen Tritici aestivi
The EC of gibberellic hypha mycelial growth suppression50Respectively 0.0510 μ g/mL and 0.3009 μ g/mL, Prochloraz is to fusarium graminearum
The inhibitory activity of mycelial growth is higher than prothioconazoles.
Prochloraz is with prothioconazoles respectively with 1:6、1:3、1:1、3:1 and 6:1 proportioning compounded combination is to wheat scab
Bacterium mycelial growth suppression EC50 be respectively 0.1337 μ g/mL, 0.0553 μ g/mL, 0.0578 μ g/mL, 0.0205 μ g/mL and
0.0424 μ g/mL, the combination of 5 kinds of compound sterilizings is respectively 132.39 to the co-toxicity coefficient (CTC) of fusarium graminearum, 244.55,
150.90,313.97 and 136.47.Result above shows, Prochloraz and prothioconazoles are with 6:1、3:1、1:1、1:3、1:6 proportionings
Compounding, potentiation is showed to fusarium graminearum, wherein 3:1 proportioning activity is most strong, and potentiation is notable.Prochloraz of the present invention
Different from prothioconazoles chemical constitution, the mechanism of action is different, and to wheat scab no interactions resistance, two kinds of composite reagents have
Beneficial to overcoming or delaying the drug-fast development of fusarium graminearum, prevention effect is improved.
2 complex composition of test example is to Spike-stalk Brown Spot of Grape bacterium indoor antibacterial test
With reference to said method, for the pathogen of Prochloraz, prothioconazoles and its different ratio to Spike-stalk Brown Spot of Grape
The mould inhibitory action of Fructus Vitis viniferae life rod method carries out indoor measurement.From Table 2, it can be seen that Prochloraz is with prothioconazoles respectively with 1:
6、1:3、1:1、3:1 and 6:1 proportioning compounded combination exists to the co-toxicity coefficient (CTC) of five proportionings of Spike-stalk Brown Spot of Grape bacterium
Between 166.34～185.25,120 are all higher than, all show as notable potentiation.
2 prothioconazoles of table are with Prochloraz different ratio to Spike-stalk Brown Spot of Grape bacterium biological activity (virulence) measurement result
3 complex composition of test example is to wheat scab and Spike-stalk Brown Spot of Grape field test
This test is carried out for the prevention effect of wheat scab and Spike-stalk Brown Spot of Grape, by above-described embodiment 1, is implemented
The antibacterial that example 2, embodiment 3, the combination sterilization composition of embodiment 4 and embodiment 5 are made respectively each by 30 grams per mu, 40
Gram, 50 grams of different consumptions use, another prepare 50 grams per mu of 50% Prochloraz wettable powder, and 10% prothioconazoles suspend
80 milliliters of per mu of agent, clear water zone is control, and totally 24 process are often processed and are repeated 3 times.Prevent and treat each plot area during wheat scab
20 square metres (kind is Yangmai 13), when Semen Tritici aestivi ears flowering 10%, spray (sprinkling wheat head portion) for the first time, every 7 days again
Spray once, totally 2 times；The sick spike number of each process and disease index, and the disease with check plot is investigated when morbidity shows disease peak in check plot
Feelings Index for Calculation is with respect to prevention effect.
During preventing and treating Spike-stalk Brown Spot of Grape (summer black kind, outdoor pergola cultivation, the age of tree 5 years), 1 plant of tree is often processed, in Portugal
Before grape first flower and after fallen flowers, each spray once spray (sprinkling fruit ear portion), investigates when morbidity shows disease peak in check plot and each processes disease
Fruit ear number (often processes 15 fruit ears of investigation), and calculates fruit ear prevention effect.
As a result as shown in table 3.
3 Prochloraz of table is prevented to the field of wheat scab and Spike-stalk Brown Spot of Grape with prothioconazoles different ratio preparation
Control effect
From table 3 it can be seen that embodiment 1, embodiment 2, embodiment 3, the composite preparation of embodiment 4 and embodiment 5, point
Not under 30g, 40g, 50g consumption, refer to prevention effect (disease refers to preventive effect) to wheat scab field disease all more than 80%, all surpass
Cross unitary agent conventional amount used disease and refer to that (with 80 milliliters, disease refers to preventive effect 74.87% to 10% prothioconazoles suspending agent mu to preventive effect；50%
Prochloraz wettable powder mu is with 40 grams, and disease refers to preventive effect 80.32%), 50 g of formulation of mu are distinguished in five embodiments, disease refers to prevent
Effect is controlled all more than 90%, especially the different amounts in embodiment 4 (A B=3 1) are used with each same preparation of other embodiment
Amount is compared, and its disease refers to that preventive effect is highest, when mu is using 30g preparation, that is, is obtained disease and is referred to preventive effect 86.45%, and mu uses 40g preparation
When, that is, obtain disease and refer to preventive effect 91.47%, and when usage amount reaches 50g, disease refers to that preventive effect reaches 96.85%.
From table 3 it can be seen that embodiment 1, embodiment 2, embodiment 3, the composite preparation of embodiment 4 and embodiment 5, point
Not under 30g, 40g, 50g consumption, to Spike-stalk Brown Spot of Grape field disease fruit fringe prevention effect (fruit ear preventive effect) all 70% with
On, all more than unitary agent conventional amount used disease refer to preventive effect (10% prothioconazoles suspending agent mu with 80 milliliters, fruit ear preventive effect
63.22%；50% Prochloraz wettable powder mu with 40 grams, fruit ear preventive effect 58.47%), in five embodiments, mu uses 50 respectively
G of formulation, fruit ear prevention effect all more than 75%, all significantly beyond unitary agent preventive effect.Especially embodiment 1 (A B=1 6),
Embodiment 2 (A B=1 3) and three different ratio of embodiment 3 (A B=1 1), its different amounts is each with other embodiment identical
Preparation consumption is compared, and its fruit ear preventive effect is all higher, when mu is using 30g preparation, that is, obtains fruit ear preventive effect more than 75%, and mu is used
During 40g preparation, that is, fruit ear preventive effect 80% is obtained, and when usage amount reaches 50g, disease refers to that preventive effect reaches 85%.
