Description
Technical field：
The invention belongs to agriculture herbicide field, be related to a kind of containing quinmerac, fluroxypyr and florasulam
Composite wheat field herbicide, prevents and kill off broad leaved weed for wheat paddock after seedling cauline leaf process.
Technical background：
Quinmerac (Quinmerac), is quinmerac, chemistry is entitled, and (the chloro- 8-Quinoline Carboxylic Acid of 3- methyl -7-, is Seedling again
The hormone like herbicide that front or after seedling uses, can be absorbed by the root of plant and leaf, then shifts to the top of plant and base portion.Quinoline
Oxalic acid is the quinoline carboxylic acid herbicide developed by BASF AG it is adaptable to cereal crop, Semen Tritici aestivi and Radix Betae, prevents and kill off pig calamity
Calamity, Herba veronicae and other weeds, wherein umbellate form section crop is very sensitive to it.
Fluroxypyr (fluroxypyr), No. CAS is:69377-81-7, fluroxypyr is inner sucting conduction type
Herbicide after seedling, is absorbed by plants after medicine quickly, makes sensitive plant the reaction of classical hormones class herbicide, plant deformity,
Distortion, finally withered.It is applied to the ground such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Semen Maydiss, Fructus Vitis viniferae, orchard, pasture, forest land, lawn and prevent and kill off broad leaved weed,
As Herba Galii Teneri, volume stem smartweed, Herba Portulacae, Herba Solani Nigri, Herba seu Flos Convolvuli arvensves, knotweed, Herba Amaranthi tricoloriss etc..
Florasulam (Diclosulam), CAS registration number：145701-21-9, structural formula is as follows：
Florasulam is the triazolopyrimidine sulfonamides herbicide developed by Dow Agrosciences LLC, can be used to
Preventing and treating broad leaved weed such as Herba Galii Teneri, Herba stellariae mediae, Polygonum weeds, compositae weeds etc..
After the herbicide of single-activity component is used for controlling weeds for a long time, the resistance of weeds can be made to strengthen, make the quick of weeds
Perception declines, and can increase formulation rate, thus causing the pollution of environment.And the development difficulty of new herbicide is increasing, expend
Time and financial resources also increasing, therefore rational mixture herbicide is to improve a kind of selection that herbicidal effect becomes current.
Herbicide rational mixture not only can expand herbicidal spectrum, delays the generation of Weed Resistance, and good compounding can also improve weeding effect
Really, play potentiation it will be apparent that improving the effect of herbicide.
Content of the invention：
It is an object of the invention to provide the low herbicidal composition of drug cost, the broad leaved weed of wheat paddock is had relatively
Good prevention effect, can be used for wheat paddock after seedling cauline leaf process, prevents and kill off broad leaved weed.The technical solution adopted in the present invention
