Description
Technical field
The invention belongs to technical field of pesticide, the rice terrace relating to a kind of herbicide, particularly pinoxaden compounding removes
Grass compositions.
Background technology
China's rice cultivation is with a long history, and region is wide, is one of View of World Rice main product state.In the 70-80 age in 20th century
Chemical herbicide enters China, prevents and kill off work to the farmland weed of China and brings Gospel, and substantial amounts of labour force is able to from heavy
Artificial weeding work in free.But the development of anything the most all has dual character, between 25 years of past, sulfonylureas
The rapid of the selective herbicide of the similar mechanisms of action such as class, amide-type and synthetic hormone class is promoted and uses year after year, and some are right
The weeds strain of all class medicaments sensitivity is eliminated, the drug resistance that less sensitive drug resistance plant produces due to gene Selection effect
Property biotype starts to rise rapidly to spread.Paddy field occurred in that after 2000 the biotype barnyard grass to dichloroquinoline acid resistance, right
Sulfonylurea resistant biotypes Monochoria korsakowii, to penoxsuam resistant biotypes barnyard grass, to cyhalofop-butyl resistant biotypes a thousand pieces of gold
Son etc..Wherein, barnyard grass, shaven head barnyard grass resistance are come with barnyard grass population Chinese and Western especially prominent, to existing mostly except barnyard grass herbicide product
Planting insensitive, become the dominant population in some areas, preventing and controlling are arduous.It is reported and measure barnyard grass pair with pot-culture method under the pool, Zhejiang
The resistance index of dichloro quinolinic acid is 123.47, this resistant biotypes weeds use individually kill barnyard grass agent such as dichloro quinolinic acid,
Bispyribac-sodium, penoxsuam, pretilachlor etc. are extremely difficult to the purpose prevented and kill off, and this kind of biotype resistant weed can slowly develop into excellent
Gesture population, strives water with Oryza sativa L. and strives fertilizer, have a strong impact on paddy growth when density is big, causes the Oryza sativa L. underproduction in various degree, threatens
The stability and development of China's Rice Production.
Pinoxaden (Pinoxaden) is by the neophyl pyrazolines of Xian Zhengda crop protection company limited of Switzerland exploitation
Herbicide, is currently used for wheatland and prevents and kill off annual gramineous weed.To upland weeds wild oat, rye grass, Herba Setariae Viridis, hard grass,
The grassy weeds such as grass, amur foxtail, Alopecurus, caput grass have good preventive effect, especially to pernicious grassy weed open country swallow
Wheat, rye grass, the most careless, careless preventive effect are close to 100%.
Summary of the invention
The invention aims to solve the technical problem that existing rice terrace resistant weed prevention effect is poor, it is provided that
A kind of rice terrace Herbicidal combinations.To this end, the present invention is by the following technical solutions:
A kind of rice terrace Herbicidal combinations, it is characterised in that: in its effective ingredient, the first effective ingredient is oxazoline grass
Ester, the second effective ingredient is pretilachlor, mefenacet, penoxsuam, cyhalofop-butyl, dichloro quinolinic acid, ethoxysulfuron, benzyl
Sulfometuron Methyl, pyrazosulfuron, different grass pine, azoles oxadiazon, bispyribac-sodium, pyribenzoxim, azoles acyl grass amine, bentazone in any one
Kind, the weight ratio of the first effective ingredient and the second effective ingredient is (1:10)～(10:1).
Further, possibly together with safener in described compositions, the mass ratio of effective ingredient and safe level is: 5～60:2
～8.
For solving above-mentioned technical problem, the present invention also can be by the following technical solutions:
A kind of rice terrace Herbicidal combinations, it is characterised in that: in described herbicide, each component is wrapped by weight percentage
Include: effective ingredient 5～60%, safener 2～8%, auxiliary agent 5～30%, solid packing or liquid diluent 5～80%, wherein
First effective ingredient is pinoxaden, the second effective ingredient be pretilachlor, mefenacet, penoxsuam, cyhalofop-butyl, two
Chloro-quinolinic acid, ethoxysulfuron, bensulfuron-methyl, pyrazosulfuron, different grass pine, azoles oxadiazon, bispyribac-sodium, pyribenzoxim, azoles acyl
Grass amine, bentazone in any one, the weight ratio of the first effective ingredient and the second effective ingredient is (1:10)～(10:1).
Pinoxaden there is no report at present for the grassy weed application preventing and kill off rice terrace, and the present inventor is to pinoxaden
Application on Oryza sativa L. conducts in-depth research, on the basis of substantial amounts of formula indoor screening test and field medicine effect test,
Find that pinoxaden, after adding safener, substantially increases the safety to Oryza sativa L., with pretilachlor, mefenacet, five fluorine
Sulphur grass amine, cyhalofop-butyl, dichloro quinolinic acid, ethoxysulfuron, bensulfuron-methyl, pyrazosulfuron, different grass pine, azoles oxadiazon, bispyribac-sodium,
After pyribenzoxim, azoles acyl grass amine, bentazone are compounding, the barnyard grass in rice terrace, rice barnyard grass, blue or green barnyard grass, shaven head barnyard grass, west are come barnyard grass,
The Weed-control effect such as Herba Digitariae, Semen Euphorbiae, Paspalum distichum, Herba Setariae Viridis, Herba Cyperi Difformis, Eclipta prostrata, short Rhizoma sagittariae sagittifoliae are excellent.And there is significantly increasing
Effect effect, expands weed control spectrum.After further study, the present invention is completed.
The invention has the beneficial effects as follows, economical and efficient, safety is high, improves the barnyard grass in rice terrace, rice barnyard grass, green grass or young crops
Barnyard grass, shaven head barnyard grass, that the grass family such as barnyard grass, Herba Digitariae, Semen Euphorbiae, Paspalum distichum, Herba Setariae Viridis, Herba Cyperi Difformis, Eclipta prostrata, short Rhizoma sagittariae sagittifoliae are carried out in west is miscellaneous
Grass, broad-leaved section weeds and the prevention effect of sedge weed, especially the preventing and treating potentiation to grassy weed are very notable, widen
Weed control spectrum, improves the degree of safety to Oryza sativa L., compounding after can reduce medication by the potentiation between different effective ingredient
Amount, saves cost accounting, slow down the generation of herbicide resistance, reduce the pollution to environment simultaneously.Meet country's decrement to use
The policy of medicine.
