Abstract
The present invention relates to a kind of Herbicidal combinations, active ingredient is benzobicylon, pyriftalid, and the ratio of weight and number of benzobicylon and pyriftalid is 60:1~1:15.The present invention substantially, improves herbicidal effect to barnyard grass, bog pondweed synergy, expands herbicide controlling spectrum, it is adaptable to prevent and kill off rice terrace annual grassy weeds.
Description
Technical field
The invention belongs to agriculture weeding technique field, and in particular to it is a kind of using benzobicylon, pyriftalid for it is effective into
The Herbicidal combinations divided, it is adaptable to prevent and kill off rice terrace annual grassy weeds.
Background technology
With high-toxic pesticide be phased out, it is necessary to efficiently, low toxicity, safety, environment amenable pharmaceutical preparations, while agriculture
The resistance to the action of a drug for making disease pest and weed of medicine is produced, the also more and more higher of the requirement to pesticide control, and this is accomplished by agricultural chemicals and ground
Hair staff development goes out the pharmaceutical preparations of highly effective and safe, meets preventing and treating and requires.Because China's pesticides discovery is at the early-stage, with autonomous
The pesticide species of intellectual property are not met by needs, therefore the new pesticide mixed preparation of exploitation, are current Agrochemicals
Only way.
Benzobicylon is researched and developed for SDS bioscience Co., Ltd. of Japan, and compound patent expires in January, 2014, mainly
For preventing and treating rice terrace barnyard grass, annual broadleaf weed and sedge weed, have very well to the weeds that sulfonylurea produces resistance
Preventive effect, the paddy field weeds such as barnyard grass, firefly Lin, Monochoria vaginalis, bog pondweed, fake rice can effectively be prevented and kill off by soil treatment, to short kind
Aunt's high dose can be only achieved preferable preventive effect, and the lasting period, the compound was that only one can be on paddy rice in the world at present up to 6 weeks
Using and to the effective medicament of fake rice.
Pyriftalid is potential difference selective agent, and the rice safety after being turned green to transplanting or rice transplanting has spy to barnyard grass before 3 leaf phases
Effect,, there is certain preventive effect to sedge weed to young age moleplant seed, lady's-grass effectively to the part such as chickweed broad leaved weed effectively.Ring
Ester grass ether is mainly moved by root absorption and to leaves and stemses, there is absorbability, also can cauline leaf absorb, the lasting period is long, in moistening bar
Or so part next month.
Rationally compounding is to improve preventive effect to herbicide, expands herbicide controlling spectrum or widens use time, delays weed community to drill
The speed replaced, reduction agricultural chemicals is single using the resistance risk brought, mitigates the pollution to environment, and reduction use cost and reduction are removed
A kind of effective ways of careless agent residual.The present inventor has made intensive studies to the mixture of benzobicylon, pyriftalid, big
On the basis of the formula indoor screening test and field medicine effect test of amount, it is found that benzobicylon, pyriftalid carry out mixture,
Synergistic function is shown to barnyard grass, bog pondweed in the range of certain mixed ratio, it is adaptable to prevent and kill off rice terrace annual miscellaneous
Grass, after further study, completes the present invention.
The content of the invention
It is an object of the invention to when solving that herbicide is single to be used it is not enough there is provided it is a kind of efficiently, low toxicity, low cost,
Quick-acting is good, and the lasting period is long, is conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
The technical scheme is that：A kind of Herbicidal combinations, by active ingredient benzobicylon, pyriftalid and appropriate
Insecticides adjuvant composition, the weight ratio of weight and number of benzobicylon and pyriftalid is 60:1~1:15.
The suitable formulation agriculturally used such as described Herbicidal combinations excipient wettable powder, water dispersible granules.
Above-mentioned Herbicidal combinations are processed into water dispersible granules, and each component percentage by weight is：Benzobicylon 0.1%~
80%, pyriftalid 0.1%~80%, surfactant 1%~20%, remaining is carrier.
Above-mentioned Herbicidal combinations are processed into wettable powder, and each component percentage by weight is：Benzobicylon 0.1%~
80%, pyriftalid 0.1%~80%, surfactant 1%~20%, remaining is carrier.
Described Herbicidal combinations are processed into water dispersible granules, wettable powder, and surfactant is detergent alkylate sulphur
Sour sodium, lauryl sodium sulfate, lignosulfonates, aliphatic alcohol sulfate, aliphatic alcohol polyethenoxy, sodium butylnaphthalenesulfonate, naphthalene
The one or more of sulfonate and formaldehyde condensation product and polycarboxylic acid；Carrier is kaolin, attapulgite, bentonite, diatomite, cunning
One or more in stone flour, precipitated calcium carbonate, urea, white carbon.
The production technology of the various application forms of described Herbicidal combinations belongs to existing known technology, will not be repeated here.
The Herbicidal combinations that the present invention is provided, it is adaptable to prevent and kill off rice terrace annual grassy weeds.
The Herbicidal combinations that the present invention is provided have the advantages that：
1st, the Herbicidal combinations that the present invention is provided, a kind of economic, environmental protection, efficient solution are provided for rice terrace chemical weed control
Certainly scheme.Composition expands the herbicide controlling spectrum of benzobicylon and pyriftalid single dose, in mixed ratio 60:1~1:15 scopes
Interior that obvious synergistic function is shown to barnyard grass, bog pondweed, the prevention effect of composition has been improved than single dose, reduced
The dosage of agricultural chemicals, reduces the risk that drug cost and agricultural chemicals are adversely affected to ecological environment.
2nd, the present invention provide for Herbicidal combinations, the single benzobicylon of long-term use or pyriftalid production can be reduced
Raw resistance risk, extends the service life of medicament, to the comprehensive regulation important in inhibiting of Weed Resistance.
