Description
Technical field
The present invention relates to a kind of Compositional type Herbicidal combinations and application thereof, be specifically related to a kind of Herbicidal combinations and application thereof containing sulfentrazone and piperazine humulone, belong to technical field of pesticide.
Background technology
Sulfentrazone, English common name: Sulfentrazone, chemical name: N-(the chloro-5-of 2,4-bis-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl) phenyl) Methanesulfomide.Sulfentrazone is sepia solid, fusing point 121-123 DEG C, vapour pressure 1.3 × 10-4 MPa (25 DEG C), proportion is 1.21g/ml (20 DEG C), in water, solvability is 0.11 (pH 6), 0.78 (pH 7), 16 (pH 7.5) (mg/g, 25 DEG C).Sulfentrazone is to belong to proporphyrinogen oxidase inhibitor, by suppressing proporphyrinogen oxidase, makes to produce in plant cell excessive protoporphyrin IX, the latter is sensitising agent, causes producing active oxygen in cell, finally causes cell membrane, vesicular membrane etc. to break, cell Dissolve things inside oozes out, withered dead.The processing of sulfentrazone cauline leaf, soil treatment all can, can be used for 1 year raw broad leaved weed, grassy weed and the nutgrass flatsedges etc. such as the Tanaka such as corn, Chinese sorghum, soybean, peanut control is led a cow, Amaranthus retroflexus, lamb's-quarters, lady's-grass, green foxtail, Siberian cocklebur.
Piperazine humulone, English name: metribuzin, chemical name: 4-amino-6-(1,1-dimethyl ethyl)-3-methyl mercapto-1,2,4-triazine-5-tetrahydrochysene ketone.Piperazine humulone sterling is colourless crystallization, 125.5 DEG C-126.5 DEG C of fusing points.20 DEG C of solvability 1.2g/L in water, are 120g/L in toluene, are 450g/L in methyl alcohol.Piperazine humulone belongs to interior suction selective herbicide, conducted to top with transpiration current by weeds Root Absorption, main by suppressing the photosynthesis performance removing activity of sensitive plant, after dispenser, each susceptible weeds sprouting is emerged unaffected, the rear blade chlorisis of emerging, last nutrition is exhausted and dead, is applicable to the multiple annual broadleaf weeds of field crops such as soybean, potato, tomato, sugarcane, corn.
The single dose of piperazine humulone and sulfentrazone all can be used for preventing and treating the annual broadleaf weed in soybean and corn field, but along with the increase of the medication time limit, exist the shortcomings such as herbicide resistance, herbicide spectrum is narrow, consumption is large, the longevity of residure is long, not only increased cost, environmental pressure also increases.If by sulfentrazone and the composite of piperazine humulone are addressed the above problem, to practical application by significant.
