Description
Technical field
It is with promazine Sulfometuron Methyl the present invention relates to a kind of Herbicidal combinations containing promazine Sulfometuron Methyl and Oxyfluorfen
It is active ingredient with Oxyfluorfen, for preventing and kill off paddy field weed, especially with Paspalum distichum (Paspalum
Paspaloides), rhizoma alismatis (Alisma plantago-aquatica), short arrowhead (Sagittaria pygmaea) are advantage
The rice terrace annual grassy weeds of weeds.
Background technology
Promazine Sulfometuron Methyl (Propyrisulfuron), it is a kind of selective broad-spectrum herbicide, to resistance to sulfonylurea herbicide
The weeds of agent have preferable preventive effect, effective to above the average age for marriage barnyard grass, nutgrass flatsedge, broadleaved herb, can foliar spray, get rid of and apply.
Oxyfluorfen (Oxyfluorfen), it is contact killing type herbicide.Its activity of weeding is played in the case where there is light.
Mainly entered by plumule, mesocotyl in plant, it is less through root absorption, and there is denier to be transported up by root
Into leaf portion, for before cotton, round onions, peanut, soybean, beet, fruit tree and vegetable fields bud, applied after bud and prevent and kill off barnyard grass, field
Cyanines, downy brome, green bristlegrass, datura, quackgrass, artemisiifolia, thorn chrysanthemum sth. made by twisting, piemarker, charlock unifacial leaf and broad leaved weed.
The present inventor has made intensive studies to promazine Sulfometuron Methyl, Oxyfluorfen mixture, finds promazine Sulfometuron Methyl, second
Oxygen AKH7088 mixture has Synergistic response to rice terrace annual grassy weeds, especially to Paspalum distichum (Paspalum
Paspaloides, PASPA), rhizoma alismatis (Alisma plantago-aquatica, ALIPL), short arrowhead (Sagittaria
Pygmaea, SAGPY) there is the response of significant Synergistic, after further study, complete the present invention.
It is an object of the invention to solve developed immunity to drugs in the prior art to farmland weed problem and actual prevention effect
It is poor, there is provided a kind of efficient, low toxicity, quick-acting are good and the lasting period is grown, and are advantageous to the Herbicidal combination of the farmland weed comprehensive regulation
Thing.
It is another object of the present invention to be used to the Herbicidal combinations prevent and kill off paddy field weed, especially with Paspalum distichum
(Paspalum paspaloides), lady's-grass (Digitaria sanguinalis), bent grass (Agrostis
