Description
Technical field
The invention belongs to preventing and controlling weed in rice field field, and in particular to be a kind of active component Bao Hanyou oxazoles acyl grass
Amine, the Herbicidal combinations of cyhalofop-butyl and the different monooctyl ester of fluroxypyr and its application.
Background technology
Paddy rice is one of China staple crops, with the continuous expansion of its cultivated area, and rice field crop smothering is constantly expanding
Production in also increasingly expand, can harm be also increasingly serious, and effectively control crop smothering in rice terrace, and stabilization of rice high yield turns into
One of major subjects of modern agricultural herbicide research.To there is herbicide controlling spectrum in current herbicide for paddy field narrow mostly, it is impossible to right
The grassy weed of Tanaka and broad leaved weed and sedge weed play extraordinary effect simultaneously, and general peasant needs secondary apply
Medicine even three dispensers can be only achieved preferable preventive effect, and chemical method weeding is agriculturally to control one of Main Means of weeds.
In recent years, because some herbicide kind large area are used alone, many weeds is already led to and are developed immunity to drugs.Meanwhile, weeds
Grass during generation is mutually complicated, and grassy weed, broad leaved weed, the mixing of nutgrass flatsedge multiclass weeds occur, and single variety herbicide is used
Farmland weed can not be solved, defect and limitation in a certain respect can be shown.Variety classes herbicide mixture, with weeding
Spectrum is wide, the characteristics of lift actual effect, delay herbicide resistance, time and labour saving.
Metamifop is aryloxyphenoxypropanoates class herbicide, and it, can as a kind of acetyl-CoA carboxylase inhibitor
Fabulous prevents and kill off most of annual gramineous weeds, from , Evil metamifops unlike most of such herbicides to water
Rice safety, can effectively prevent and kill off rice terrace main weeds, such as barnyard grass.Metamifop can effectively prevent and kill off grassy weed, but to wealthy
Leaf weeds and sedge weed preventive effect are poor, but weeds in field be often grassy weed, broad leaved weed and sedge weed simultaneously
In the presence of therefore, in order to make up the deficiency of single dose, it is necessary to which the weeds of itself and other species are carried out into compounding use.
Cyhalofop-butyl is the only kind to paddy rice with tight security in fragrant phenoxy phenoxy propionic acid herbicide, be also in
Inhale systemic herbicides.Absorbed by the blade and leaf sheath of plant, bast conduction accumulates the meristem zone in plant,
Resist acetyl-CoA carboxylase（ACCase）, make aliphatic acid synthesis stopping, the growth division of cell can not be normally carried out, membrane system
The destruction of the structures containing fat such as system, finally results in Plant death.Cyhalofop-butyl prevents and kill off the malignant weed of rice terrace especially to moleplant seed etc.
There is the effect of brilliance.But it is slower to be absorbed into weeds Mortality Ratio from cyhalofop-butyl, generally requires 1-3 weeks.Time length, list
One produces resistance seriously using cyhalofop-butyl, causes dosage increasing, and cyhalofop-butyl is poor to preventing and kill off broad leaved weed effect,
It is especially poor to broad leaved weed effect, while to part grassy weed effect also poor such as above the average age for marriage barnyard grass, lady's-grass.Therefore we need
Need to look for an outstanding herbicide of rice terrace to carry out mixture, increase herbicidal effect, reduction cyhalofop-butyl resistance make up cyhalofop-butyl
It is not enough.
Fluroxypyr is absorbed by plants quickly after inner sucting conduction type herbicide after seedling, medicine, goes out sensitive plant
The reaction of existing classical hormones class herbicide, plant deformity, distortion are final withered, have special efficacy to preventing and kill off broad leaved weed;Such as eye
Dish, Monochoria vaginalis effect are good, can effectively make up the deficiency of cyhalofop-butyl.
