Description

A kind of composition pesticide containing fluorine phonetic oxime grass ether
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of with fluorine phonetic oxime grass ether, 4-ammonia The chloro-5-of base-3 fluoro-6 (the chloro-2-of 4-fluoro-3-methoxyphenyl)-pyridine-2-carboxylic acids benzene methyl is The Synergistic response composition pesticide of effective ingredient, it is adaptable to prevent and kill off rice terrace annual miscellaneous Grass, especially with Semen Euphorbiae (Leptochloa chinensis, LEPCH), Herba Ludwigiae Prostratae (Ludwigia prostrata, LUDPR), Leersia Sw (Leersia hexandra, LEEHE) Rice terrace annual grassy weeds for advantage weeds.
Background technology
Fluorine phonetic oxime grass ether is introducing fluoroform on the ad-hoc location of pyrimidine salicylic acid compounds Base replaces gained, belongs to inhibitor of acetolactate synthetase, and it is to perennial and annual standing grain originally Section weeds demonstrate excellent prevents and kill off performance, is wide spectrum selective post-emergence herbicide, particularly To preventing and kill off rice terrace barnyard grass, Paspalum distichum, rice barnyard grass, red foot barnyard grass have specially good effect, mu consumption to be 2-6 Gram, fluorine phonetic oxime grass ether has the safety of height to Oryza sativa L.,
The chloro-5-of 4-amino-3 fluoro-6 (the chloro-2-of 4-fluoro-3-methoxyphenyl)-pyridine-2-carboxylic Acid benzene methyl is novel aromatic yl pyridines first acid herbicides, belongs to growth regulator class herbicide Member, to grassy weed such as barnyard grass, Semen Euphorbiae, sedge weed such as cyperus iria, wafts Stroking grass etc., broad leaved weed such as Rhizoma Alismatis, Rhizoma sagittariae sagittifoliae, Monochoria korsakowii etc. are respectively provided with activity of weeding, to water Rice safety.
By test, we have found that fluorine phonetic oxime grass ether and the fluoro-6 (4-of the chloro-5-of 4-amino-3 Chloro-2-fluoro-3-methoxyphenyl)-pyridine-2-carboxylic acids benzene methyl is to Semen Euphorbiae (Leptochloa Chinensis, LEPCH), barnyard grass (Echinochloa crusgalli, ECHCR), Paspalum distichum (Paspalum paspaloides, PASPA), Leersia Sw (Leersia Hexandra, LEEHE), ditch millet (Paspalum thunbergii, PASTH), Hunan Carex baccans Nees (Echinochloa frumentacea, ECHFR), Herba Ludwigiae Prostratae (Ludwigia Prostrata, LUDPR), Alternanthera philoxeroides (Alternanthera philoxeroides, ALTPH), Eclipta prostrata (Eclipta prostrata, ECLPR), Rhizoma sagittariae sagittifoliae (Sagittaria Trifolia, SAGTR), short Rhizoma sagittariae sagittifoliae (Sagittaria pygmaea, SAGPY), duck The sole of the foot grass (Commelina communis, COMCO), cyperus iria (Cyperus iria, Etc. CYPIR) there is synergistic function.
Fluorine phonetic oxime grass ether and fluoro-6 (the chloro-2-of the 4-fluoro-3-methoxyphenyls) of the chloro-5-of 4-amino-3 -pyridine-2-carboxylic acids benzene methyl compounding to Semen Euphorbiae (Leptochloa chinensis, LEPCH), Herba Ludwigiae Prostratae (Ludwigia prostrata, LUDPR), Leersia Sw (Leersia hexandra, LEEHE) there is the response of significant Synergistic.
