Abstract
The invention discloses a synergistic weeding composition, which is characterized in that the synergistic weeding composition is prepared by using glufosinate and s-metolachlor as active ingredients in a compound way, and the weight ratio of the glufosinate to s-metolachlor is (1-80): (1:80). The synergistic weeding composition has the advantages that the weeds on the ground can be killed, the weed seeds which are about to germinate can also be killed at the same time and the efficacy duration is long; the weeding spectrum is wide and the synergistic weeding composition can be widely used for weeding in dry lands; and the toxicity is low, the sensitization is weak, the toxicity to crops, human and livestock is low, the weeds can be safely removed under the situation that the crops are not damaged, the weeding synergistic effect is obvious and the generation speed of pesticide resisting capacity of the weeds is slowed down.
Description
Technical field
The present invention relates to technical field of pesticide, specifically, relate to a kind of Synergistic herbicide compositions.
Background technology
Crops all need be used a large amount of weed killer herbicides for this reason and carry out weed control to retrieve crop yield loss because weeds harm causes crop yield to reduce every year.In recent years, weeds are more and more serious to the harm on the crops, and because the abuse of weed killer herbicide causes weeds that agricultural chemicals is produced increasing resistance, cause weed control efficacy to reduce year by year.
Current, popular steriland herbicide has three kinds:
(1) paraquat, chemical name are 1-1-dimethyl-4-4-bipyridine cation salt, are a kind of quick steriland herbicides, have action of contace poison and certain systemic action.Be characterized in: 1, can make it withered, the not effect of non-chlorenchyma rapidly by the green plant tissue absorption; 2, in soil, combine and purifying with soil rapidly, invalid to plant root and perennial subterranean stem and perennial root.Because paraquat is very big to people's toxicity, and does not have special efficacy antidote, the oral ingestion lethality can reach more than 90%, has been forbidden by more than 20 countries at present or strict restriction use.
(2) glyphosate, claim again: glyphosate, farming reach (Roundup), careless dried phosphine, the sweet acid of phosphine, are the steriland herbicides of present world sales volume first.Glyphosate is the chronic wide spectrum steriland herbicide of inner sucting conduction type; The main interior enol acetonyl shikimene phosphate synthase of object that suppresses; Thereby suppress the conversion of shikimene, make synthetic being interfered of protein cause plant dead to phenyl alanine, cruel propylhomoserin and tryptophan.But its fatal weakness is exactly the yield and quality that influences crop, and it is slower to eliminate the efficient of weeds, and the time is longer, and is bigger to the harmful effect of soil.
(3) careless ammonium phosphine; Chemical name: 4-[hydroxyl (methyl) phosphono]-DL-high lactamine belongs to broad-spectrum touch-out type weed killer herbicide, and systemic action is not strong; To kill root different with glyphosate; Grass ammonium phosphine kills leaf earlier, can conduct at the plant xylem through the plant transpiration effect, between its quick-acting between paraquat and glyphosate.Since low to people's toxicity, also as safe as a house to crop, so careless ammonium phosphine is the major product of the steriland herbicide of China's emphasis popularization.But careless ammonium phosphine can only kill the grass that we can see, and is invalid to grass seeds, so the lasting period can be not oversize, approximately just about 20 days.
In addition, also having a kind of preemergence herbicide, is exactly essence-isopropyl methoxalamine, and its weeding principle is that weeds killed grass seeds in the budding period, and it does not have effect to the weeds more than three leaves.
Summary of the invention
The purpose of this invention is to provide the Synergistic herbicide compositions that a kind of lasting period is long, have the wider control efficiency of killing grass spectrum and excellence.
For addressing the above problem, the technical scheme that the present invention adopted is:
A kind of Synergistic herbicide compositions is characterized in that: it is formed as active component is composite by careless ammonium phosphine and essence-isopropyl methoxalamine, and the weight ratio of active component is: careless ammonium phosphine: essence-isopropyl methoxalamine=1-80: 1-80.
Say further:
The weight ratio of said active component is: careless ammonium phosphine: essence-isopropyl methoxalamine=2: 3.
The percentage by weight of said active component in Herbicidal combinations is 40～60%.
Further say:
Said Herbicidal combinations be missible oil, micro emulsion, water and milk, suspending agent (comprising: do outstanding, water is outstanding and oil outstanding), all formulations such as pulvis, soluble liquid, wetting powder, granula, soluble powder, water dispersible granules or suspension emulsion.
Owing to adopted technique scheme, compared with prior art, the present invention has the following advantages: when the weeds with ground kill, can also be with killing the grass seeds that will germinate, and the lasting period is long; Broad weed-killing spectrum can be widely used in the nonirrigated farmland management of weeds; Low, the weak sensitization of toxicity, low to crop, people and animals' murder by poisoning, can be under the situation that does not injure crop, the synergistic effect of management of weeds, and weed control safely is remarkable, slows down the generation of weeds to pesticide resistance.
Below in conjunction with embodiment the present invention is further specified.
Embodiment
Embodiment 1:50% grass ammonium phosphine essence-isopropyl methoxalamine missible oil
Take by weighing active component and be dissolved in the solvent, and then add emulsifier, stir, promptly make 50% careless ammonium phosphine essence-isopropyl methoxalamine missible oil.
Embodiment 2:50% grass ammonium phosphine essence-isopropyl methoxalamine missible oil
Take by weighing active component and be dissolved in the solvent, and then add emulsifier, stir, promptly make the 50% careless ammonium essence-isopropyl methoxalamine missible oil of seeing.
Embodiment 3:40% grass ammonium phosphine essence-isopropyl methoxalamine missible oil
Take by weighing active component and be dissolved in the solvent, and then add emulsifier, stir, promptly make 40% careless ammonium phosphine essence-isopropyl methoxalamine missible oil.
Embodiment 4:60% grass ammonium phosphine essence-isopropyl methoxalamine missible oil
Take by weighing active component and be dissolved in the solvent, and then add emulsifier, stir, promptly make 40% careless ammonium phosphine essence-isopropyl methoxalamine missible oil.
Embodiment 5: careless ammonium phosphine essence-isopropyl methoxalamine emulsion
Embodiment 6: careless ammonium phosphine essence-isopropyl methoxalamine emulsion
The test of pesticide effectiveness of Herbicidal combinations management of weeds according to the invention is following:
1, test method
Adopt pot-culture method, select sizeable plastics nutritive cube for use, interior dress is adopted back from the farmland through air-dry topsoil, and soil moisture all is controlled at 20%, and the weed seed of sowing full seed homogeneous is sprayed 450 kilograms/hectare of spray amount to upper soll layer behind the blinding.After two weeks, investigate the strain preventive effect of various weeds.The weeds that are for experiment are barnyard grass grass, eleusine indica, Herba portulacae.More than test all repeats 4-6 time, handles repetition 3-5 basin at every turn.
The test medication is embodiment of the invention 1-embodiment 4 described four kinds of careless ammonium phosphine essence-isopropyl methoxalamine missible oil, and every mu of consumption 100ml carries out indoor bioassay respectively.
2, result of the test sees the following form
Can find out that from last table the present invention is higher to the preventive effect of weeds, wherein best according to the control efficiency of 50% formulated careless ammonium phosphine essence-isopropyl methoxalamine missible oil of embodiment 1 described proportioning.
