Abstract
The invention relates to a weeding composition containing fluorine pyribenzoxim and carfentrazone-ethyl, which has the effective ingredients of the fluorine pyribenzoxim and the carfentrazone-ethyl, wherein the weight percentage of the fluorine pyribenzoxim in the composition is 0.1-80 percent, the weight percentage of the carfentrazone-ethyl in the composition is 0.1-80 percent, and the balance of pesticide auxiliary. The weeding composition containing the fluorine pyribenzoxim and the carfentrazone-ethyl has synergistic interaction respond to target weeds, and is suitable for controlling and eliminating annual weeds of paddy field, especially annual weeds of paddy field with paspalum distichum, eclipta prostrata and scirpus juncoides roxb as dominant weeds.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic response composition pesticide being active ingredient with the phonetic oxime grass ether of fluorine and azoles humulone, be applicable to prevent and kill off paddy field annual weed, especially with Paspalum distichum (Paspalum paspaloides, PASPA), Eclipta prostrata (Eclipta prostrata, ECLPR), firefly Lin (Scirpus juncoides, SCIJU) paddy field annual weed that is advantage weeds.
Background technology
Fluorine phonetic oxime grass ether on the ad-hoc location of pyrimidine salicylic acid compounds, introduces trifluoromethyl replace gained, belong to inhibitor of acetolactate synthetase, it demonstrates perennial and annual gramineous weed and excellent prevents and kill off performance, it is wide spectrum selective post-emergence herbicide, particularly to preventing and kill off paddy field barnyard grass, Paspalum distichum, rice barnyard grass, red pin barnyard grass have special efficacy, mu consumption is 2-6 gram, and fluorine phonetic oxime grass ether has the safety of height to paddy rice
Azoles humulone (Carfentrazone-ethyl) is a kind of contact killing type selective herbicide, under the condition having light, in chlcrophyll biosynthesis process, by the accumulation suppressing proporphyrinogen oxidase to cause poisonous intermediate, thus destroy the cell membrane of weeds, make blade withered, dead rapidly.Namely azoles humulone is absorbed by plant leaf blade in 15 minutes after spray medicine, and it is not drenched with rain affects, and after 3 to 4 hours, weeds just occur poisoning symptom, and 2 to 4 days dead
By test, we have found that the phonetic oxime grass ether of fluorine and azoles humulone are to barnyard grass (Echinochloacrusgalli, ECHCR), Paspalum distichum (Paspalum paspaloides, PASPA), Leersia Sw (Leersia hexandra, LEEHE), ditch millet (Paspalum thunbergii, PASTH), Hunan barnyard grass (Echinochloa frumentacea, ECHFR), false loosestrife (Ludwigia prostrata, LUDPR), cyperus iria (Cyperus iria, CYPIR), difformed galingale herb (Cyperus difformis, CYPDI), wild water chestnut (Heleocharis plantagineiformis, HELPL), firefly Lin (Scirpusjuncoides, SCIJU), arrowhead (Sagittaria trifolia, SAGTR), Alternanthera philoxeroides (Alternanthera philoxeroides, ALTPH), Eclipta prostrata (Eclipta prostrata, ECLPR), etc. there being synergistic function.
