Abstract
The invention belongs to the field of pesticide, relating to a hybrid weeding composite containing Bispyribac-sodium and cyclosulfamuron. The weeding composite takes the Bispyribac-sodium and the cyclosulfamuron as main effective ingredients with the mass ratio of (0.1-80):(0.1-80). In the weeding composite disclosed by the invention, different surfactants, thickeners, solvents or solid fillers and the like can be added to be processed into various dosage forms, such as missible oil, a suspending agent, water dispersible granules, wettable powder and the like. The compound weeding prearation can be used for preventing and removing paddy field grass family weeds, broad leaf weeds and cyperaceae weeds. On the premise of improving pesticide effect, the weeding composite can delay weed resistance, has the advantages of wide weeding spectrum and long effect lasting period if being compared with a single agent, is safe to the paddy and next batch of crop and is an ideal paddy field herbicide.
Description
Technical field
The invention belongs to technical field of pesticide, especially the weed killer herbicide field relates to the binary built agent of two careless ethers and AC322140.This Herbicidal combinations can be used the paddy field postemergence weed control.
Background technology
Two careless ethers have another name called Nong Meili, the salicylic acid Sulfadiazine Compound, and chemical name: 2, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of 6-.Belong to phenoxy carboxylic acid herbicides, mainly hindered aminoacid biosynthesis side chain is selective herbicide through the acid of root leaf absorption inhibition vinegar milk is synthetic, uses rice direct-seeding Tanaka, and herbicidal spectrum is wide.Its structural formula is following:
This medicament is to belong to benzoic acid derivative, is highly active ALS inhibitor, and efficient, wide spectrum, consumption are extremely low.Effectively prevent and kill off barnyard grass in paddy field and other grassy weeds, double most of broad leaved weeds, some sedge weeds and the Stam F-34 controlled produces resistance barnyard grass grass.
AC322140 has another name called the gold autumn.Chemical name: 1-{ [O-(ring propiono) phenyl] sulfonamides }-3 (4,6-dimethoxy-2-pyridine radicals)-ureas, structural formula is:
This medicine can be by weeds root system and Foliage Absorption; In the plant body, conduct, its mechanism of action mainly passes through to suppress the activity of acetolactate synthestase in the weeds body, thereby hinders the synthetic of branched-chain amino acids such as leucine, isoleucine, a word used in person's names propylhomoserin; Make cell stop division, cause weeds dead at last.After doing the cauline leaf processing, susceptible weeds stops growing, and the leaf look moves back green, according to different environmental conditions, just can make weeds withered fully through after several weeks.This medicine can be used for the rice transplanting Honda, also can be used for direct sowing rice field and prevents and kill off broad leaved weed and sedge weed, under high dose, the barnyard grass grass is had good inhibitory effect, and the anti-weeds flat bar bamboo trunk grass of perennial difficulty is also had stronger inhibition effect.
Summary of the invention
The present invention is according to the present situation of present paddy field herbicide after seedling; And behind the paddy field seedling weeds a situation arises; Provide a kind of by two careless ethers and the composite binary mixed herbicidal composite of AC322140; This Herbicidal combinations can not only improve the preventive effect of medicament to weeds, and to when stubble and succession crop safety, has reduced peasant's drug cost simultaneously.
The purpose of this invention is to provide a kind of mixed herbicidal composite that contains two careless ethers and AC322140, it is characterized in that this weed killer herbicide is main active ingredient with two careless ethers and AC322140, the mass ratio of two careless ethers and AC322140 is 0.1～80: 0.1～80.Preferred two careless ethers are 1～40: 1～60 with the mass ratio of AC322140, and are further preferred 1～30: 1～30, most preferably 1～15: 1～15.
In mixed herbicidal composite, the two quality percentage composition in Herbicidal combinations of two careless ethers and AC322140 is 1～85%, and the preferred mass percentage composition is 10～80%.
In the binary built preparation of two careless ether of the present invention and AC322140; Except two kinds of active ingredients; Different surfaces activating agent, thickener, solvent or solid packing etc. can also be added, multiple formulations such as missible oil, suspending agent, water dispersion granule, wetting powder can be processed into.
Combinations of herbicides of the present invention is mainly used in the paddy field postemergence weed control, can prevent and kill off various grassy weeds, broad leaved weed and sedge weed effectively, particularly prevents and kill off annual gramineous weed, broad leaved weed and sedge weed.Especially can improve preventive effect to grassy weed.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal combinations of the present invention can kill weeds through two kinds of different mechanism, makes weeds resistance generation speed reduce, and greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Two careless ethers are broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and AC322140 is mainly to be the weed killer herbicide of preventing and kill off sedge weed and broad leaved weed.After both mixed, can improve had preventive effect to multiple grassy weed, broad leaved weed and sedge weed, thereby has prolonged the lasting period of medicament.
3, safe.Because its using dosage is under control, and makes medicament under the prerequisite that has improved drug effect, its safety to paddy field and succession crop also is improved.
The practical implementation method
Herbicidal combinations of the present invention is according to the former medicine correlation properties of two careless ethers and AC322140, with and weeder reason etc., can be processed into missible oil, suspending agent, aqueous emulsion, do multiple formulations such as hanging agent, water dispersion granule, wetting powder.Two kinds of content of effective in the Herbicidal combinations of the present invention are not limited to the scope in following examples.
