Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of composition pesticide that contains careless ammonium phosphine, be used for controlling weeds.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", namely (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of effective approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Grass ammonium phosphine (glufosinate-ammonium) chemical name: (RS)-2-amino-4-(hydroxymethyl oxygen see base) butyric acid ammonium, molecular formula: C

4P.Grass ammonium phosphine belongs to the acid herbicides of seeing, and is glutamine synthetase inhibitor, has the non-selective contact weedicide of part systemic action.In the short time, disorder is sunk in the ammonium metabolism in the plant corpus after the dispenser, and the cytotoxic agent ammonium ion is accumulated in plant corpus, and meanwhile, photosynthesis is reached the weeding purpose by severe inhibition.
Pyrrole grass ether (pyraflufen-ethyl) chemical name: 2-chloro-5-(4-chloro-5-difluoro-methoxy-1-methylpyrazole-3-yl)-4-fluorophenoxy ethyl acetate, molecular formula: C

2Diflufenican is used the medicine soil layer that can form at the soil table anti-leaching before and after weeds germinate, keep active whole vegetative period crop.When weed germination all can absorb medicament by medicine soil layer young shoot or root system, this agent has the carotenoid of inhibition biosynthesis effect, carotenoid content descends in the weeds plant of absorption medicament, cause chlorophyll destroyed, membranolysis, weeds then show as young shoot decolouring or white, and last whole strain is wilted dead.
Mesotrione (mesotrione) chemical name: 2-(2-nitro-4-mesyl benzene adds acyl) cyclohexane-1,3-diketone, molecular formula: C
14H

7S.Mesotrione suppresses the activity of PHPPA dioxygenase (HPPD), and HPPD can be converted into plastoquinone with amino acid Lip river propylhomoserin.Plastoquinone is the co-factor of phytoene desaturase, is the biosynthetic key enzyme of carotenoid.Use 3-5 days implants meristematic tissue of mesotrione the yellow symptom to occur and cause withered spot thereupon, spread all over whole strain plant behind the fortnight.
The chemical composition of each weed killer herbicide, formation and physic-chemical property all are distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
Along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, extensively is recognized as one of important measures that weed killer herbicide rationally uses, and has worked out a series of Herbicidal compositions, has obtained greater advance.
My company also is devoted to the research and development of Herbicidal compositions.At present, have no report about careless ammonium phosphine with the relevant composite product of pyrrole grass ether, diflufenican, mesotrione.
