Description
Technical field
The present invention relates to the Herbicidal composition for rice field containing furans sulphur humulone and pyraclonil, be with furans sulphur humulone and
Pyraclonil is effective ingredient, for preventing and kill off rice terrace annual grassy weeds, belongs to composition pesticide field.
Background technology
Chemical method weeding is agriculturally to control one of Main Means of weeds.In recent years, due to some herbicide kinds
Large area is used alone, and already leads to many weeds and develops immunity to drugs.Meanwhile, grass when weeds occur is mutually complicated, not only 1 year
The mixed life of raw and perennial weeds, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, and low age, advanced age are miscellaneous
Grass staggeredly occurs, so during the exclusive use of herbicide kind, can show defect and limitation in a certain respect.
Furans sulphur humulone is the benzene first by Bayer and the enterprise such as Bei Xing KCCs and Zennoh of Japan joint development
Acyl group cyclohexyl diketone herbicide.Furans sulphur humulone mainly acts on 4- para (ortho)-hydroxybenzoic acetone acid dioxygenase (HPPD)s, so as to suppress miscellaneous
The synthesis of careless pigment.Awns cyperus iria is belonged to extensively for herbicide controlling spectrum and the weeds of resistance to sulfonylurea herbicide have excellent preventive effect,
Available for preventing and kill off for rice terrace annual grassy weeds.
Pyraclonil belongs to proporphyrinogen oxidase (PPO) inhibitor, by German Schilling company (be afterwards Sanofi-Aventis, after
And by Beyer Co., Ltd) develop, it is introduced by Japanese eight continents chemical company, therefore Japanese eight continents chemical company mainly pays attention to this removes
The application study of careless agent.It is general to be carried out handling with pyraclonil in paddy field barnyard grass early period of origination and effectively be prevented and kill off, while right
A variety of annual grassy weeds and perennial weeds are also effective.In addition, the herbicide has resistance to some to sulfonylurea herbicide
Weeds also have good effect.Rice terrace annual gramineous weed, nutgrass flatsedge and some broad leaved weeds etc. mainly are prevented and kill off, wherein wrapping
Include：Difformed galingale herb, rice barnyard grass, barnyard grass, moleplant seed, waterwort, needle spikesedge herb, Procumbent Falsepimpernel, Monochoria vaginalis and mexicana etc..It is used for water after bud
Behind rice field, medicament is mainly by the root system and cauline leaf basal sink of weeds, generally after medication in 2 days, weeds cauline leaf chlorisis, hair
It is red, necrosis, final dead, the lasting period is up to 50d.
Furans sulphur humulone and pyraclonil are single in use, there is certain defect and limitation.
The present inventor has made intensive studies to the mixture of furans sulphur humulone and pyraclonil, in substantial amounts of formula indoor sieve
On the basis of choosing experiment and field medicine effect test, it is found that furans sulphur humulone and pyraclonil carry out mixture, in certain mix ratio
Obvious synergistic effect is shown to paddy field weed in the range of example, after further study, the present invention is completed.
The mixture and application of furans sulphur humulone and pyraclonil there is no report at present.
The content of the invention
Technical problem to be solved：It is an object of the invention to solve the deficiency in above-mentioned herbicide actual use, carry
It is good for a kind of efficient, low toxicity, low cost, quick-acting, and the lasting period is long, is conducive to the Herbicidal combination of the weeds in paddy field comprehensive regulation
Thing.
It is a further object of the present invention to provide be applied to the Herbicidal combinations to prevent and kill off rice terrace annual grassy weeds.
Technical scheme：To achieve the above object, the present invention provide it is a kind of using furans sulphur humulone and pyraclonil for it is effective into
The ratio of weight and number of the Herbicidal combinations of part, furans sulphur humulone and pyraclonil is 10：1~1:10.

Assays Example one：Furans sulphur humulone is determined with pyraclonil mixture to the synergy of paddy field weed
To further appreciate that furans sulphur humulone and synergy of the pyraclonil mixture to paddy field weed, the present inventor couple
Furans sulphur humulone has carried out formula indoor screening test with pyraclonil mixture：
Test material：
Chickweed [Stellaria media (L.) Cyrillus] (field collection Seed storage).
Barnyard grass [Echinochloa crusgalli (L.) Beaw Setaria] (field collection Seed storage).
Test apparatus：
Controllable illumination box；POTTER precision laboratory spray towers；Electronic balance (sensibility reciprocal 0.1mg)；Micropipette rifle
Deng.
Test method：
The purity for first weighing certain mass is 98% furans sulphur humulone active compound, and purity is 96% pyraclonil active compound, is added
Acetone is diluted after fully dissolving with the 0.1% Tween 80 aqueous solution, and single dose mother liquor is configured to respectively, system is set according to mixture purpose
Row proportioning, each proportioning sets 5~7 concentration gradients.Representative susceptible weeds seed is selected according to single dose herbicide controlling spectrum,
Culture is standby to the heart of 1 leaf 1.By after the weeds cauline leaf process for selecting numbering, incubated at room temperature 5 days in illumination box are placed on, are calculated
Prevention effect (fresh weight), then calculates dense EC in suppressing with least square method50(95% confidence limit), then calculated altogether with the abundant methods of Sun Yun
Malicious coefficient (CTC).
Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜
Co-toxicity coefficient (CTC) ＜ 120 shows as summation action.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100
Theoretical toxicity index (TTI)=(A percentage composition in A toxicity index × mixture)+(B toxicity index × mixed
B percentage composition in agent)
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100
Measurement result shows (see Tables 1 and 2) that furans sulphur humulone is with pyraclonil in mixed ratio 10:1~1:10 it
Between, with obvious synergistic effect, co-toxicity coefficient is more than 120.
The synergy of table 1, different ratio furans sulphur humulone and pyraclonil to nutgrass flatsedge is determined
The synergy of table 2, different ratio furans sulphur humulone and pyraclonil to barnyard grass is determined
