Description
Technical field
The present invention relates to wheat diseases preventing and treating, and in particular to a kind of composition pesticide of fluorine-containing azoles bacterium acyl azanol and Prochloraz
And its application.
Background technology
Wheat scab (the Fusarium Head as caused by fusarium graminearum (Gibberella zeae)
Blight), it is a disease generally occurred in the world.Wheat scab not only results in serious economic loss,
Also food security is seriously threatened because producing mycotoxin.Because Disease Resistance of Wheat Varieties is generally poor, chemical control is always
Mitigate the key of head blight occurrence degree.In China, since the seventies in last century, carbendazim is in wheat scab control and application
It is upper to have more than 40 years.
Since 1992, since resistant strain of Haining City discovery Gibberella zeae bacterium in Zhejiang Province's to carbendazim, in river
There is the generation of carbendazim resistance population in various degree with spreading in Su Sheng, Shanghai City and Anhui Province.Due to Gibberella zeae bacterium
Generation to carbendazim-resistance, in multiple areas such as Jiangsu Province after 1998, carbendazim is anxious to the preventive effect of wheat scab
Play declines.As the development of resistant population is with spreading, once the weather condition of wheat heading flowering period is suitably fallen ill, you can causes
Resistance to the action of a drug plant disease epidemic, then may result in the forfeiture of carbendazim preventive effect.In recent years, wheat scab the middle and lower reach of Yangtze River, Yangze river and Huai river,
The Yellow River and Huai He River south area of wheat is very popular, the Yellow River and Huai He River the north area of wheat lay particular stress on it is popular, occurring area and preventing and treating area 100,000,000 mu and 200,000,000 mu it is secondary with
On, and have the trend of the Huaihe River for progressively spreading to northern China and the Huanghe valley.
Fluorine azoles bacterium acyl azanol is a kind of new butanedioic acid deoxidation enzyme inhibitor class first just researched and developed up to (China) Co., Ltd

A kind of rare new medicament of wheat scab is prevented and treated in global range.
Prochloraz for efficiently, wide spectrum, low-toxicity imidazoles bactericide, mainly by suppressing the biosynthesis of cause of disease fungisterol
And drug effect is played, with multiple actions such as prevention, protection and treatments, for multiple diseases preventive effect caused by sac fungus and Fungi Imperfecti
It is splendid.In recent years, the medicament is to prevent and treat the emphasis medicament that carbendazim is substituted in wheat scab, and controlling for the property of medicine is resisted in production
Significant role has been waved in haircut.

By 20% fluorine azoles bacterium acyl azanol Prochloraz SC (fluorine azoles bacterium acyl azanols obtained by embodiment 5:Prochloraz=1:2),
And the 20% Prochloraz SC for preparing Prochloraz active compound by embodiment 5 and 20% fluorine azoles bacterium acyl azanol SC [first just have up to (China)
Limit company] single dose contrast is done, while using 50% carbendazim WP (Yangnong Chemical Co., Ltd., Jiangsu) as comparison medicament, opening
Exhibition prevents and treats the field control effectiveness test of wheat scab.
Test process method：Test site is located at the agricultural technology renovation of Jiangsu Hilly Ground Zhenjiang Agriculture Science Research Institute
Experimental plot in the garden of center, soil is horse liver soil, middle fertility, the content of organic matter 1.75%.Wheat breed is town wheat No. 10,
Field management conventional during experiment.Experiment sets 6 processing, is respectively：The Hes of 20% fluorine azoles bacterium acyl azanol Prochloraz SC 600
900g/hm2, 20% fluorine azoles bacterium acyl azanol SC 900g/hm2, 20% Prochloraz SC 900g/hm2, 50% carbendazim WP 1500g/
hm2(recommended dose) and clear water blank control.Each processing is repeated 3 times, totally 18 cells, and plot area is 30m2, cell sets guarantor
Shield row and random district's groups arrangement.(on April 25th, 2017) dispenser 1 time when wheat flowering 10%, spouting liquid is 750L/hm2, it is empty
White check plot sprays equivalent clear water.Other bactericide are no longer sprayed during experiment, field management is routinely carried out.Wheat scab
Incidence is investigated after generation is stable, respectively handling wheat scab using 5 sampling surveys of diagonal, a situation arises, often handles
About 500 fringes are investigated, and calculate disease index and prevention effect.Disease index and prevention effect calculation formula are respectively：The state of an illness refers to
Number=[Σ (sick spike numbers at different levels × corresponding sick the value of series)/total spike number × superlative degree typical value of investigation] × 100；Prevention effect=
[(control disease index-processing disease index)/control disease index] × 100%.
Result of the test is drawn, preventive effect is referred to from high to low for 5 medicament applications, the 1 sick fringe and disease to wheat scab of examination
It is followed successively by 20% fluorine azoles bacterium acyl azanol Prochloraz SC 900g/hm2, 20% fluorine azoles bacterium acyl azanol SC 900g/hm2, 20% fluorine azoles
Bacterium acyl azanol Prochloraz SC 600g/hm2, 20% Prochloraz SC 900g/hm2With 50% carbendazim WP 1500g/hm2.20%
Fluorine azoles bacterium acyl azanol Prochloraz SC 900g/hm2Preventive effect to wheat scab is above the fluorine azoles bacterium acyl azanol SC of single dose 20%
With 20% Prochloraz SC 900g/hm2And the carbendazim WP 1500g/hm of comparison medicament 50%2Preventive effect and significant difference (table
2).This shows that the pesticide combination of fluorine-containing azoles bacterium acyl azanol and Prochloraz is preferable to the preventive effect of wheat scab, the field compared with single dose
Between drug effect also synergy is obvious；Preventive effect when being applied under doses is significantly better than conventional dose carbendazim and applied under recommended dose
Preventive effect, the results are shown in Table 2.
Field efficacies (dispenser 1 time) of the fluorine azoles bacterium acyl azanol Prochloraz SC of table 2 20% to wheat scab
Note:Significant difference (P is represented with different lowercase persons are indicated after column data<0.05).
