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 weed killer herbicide field, relates to the binary built agent of two careless ether and AC322140.This Herbicidal combinations can be applied paddy field postemergence weed control.
Background technology
Two careless ether, has another name called Nong Meili, salicylic acid Sulfadiazine Compound, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of chemical name: 2,6-.Belong to phenoxy carboxylic acid herbicides, mainly by the acid of root leaf absorption inhibition vinegar milk is synthetic, hindered aminoacid biosynthesis side chain is selective herbicide, rice direct-seeding Tanaka, uses, and herbicidal spectrum is wide.Its structural formula is as follows:
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.
AC322140, has another name called the gold autumn.Chemical name: 1-{[O-(ring propiono) phenyl] sulfonamides }-3 (4,6-dimethoxy-2-pyridinyl)-urea, structural formula is:
This medicine can be by weeds root system and Foliage Absorption, in plant body, conduct, its mechanism of action is mainly by suppressing the activity of acetolactate synthestase in weeds body, thereby the branched-chain amino acids such as obstruction leucine, isoleucine, a word used in person's names propylhomoserin is synthetic, make cell stop division, finally cause weeds death.Do after cauline leaf processing, susceptible weeds stops growing, and leaf look moves back green, according to different environmental conditions, just can make weeds completely withered after several weeks.This medicine can be used for 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, barnyard grass is had to good inhibitory action, and the anti-weeds flat bar of perennial difficulty bamboo trunk grass is also had to stronger inhibition.
Summary of the invention
The present invention is according to the present situation of current paddy field herbicide after seedling, and after paddy field seedling weeds a situation arises, provide a kind of by two careless ether 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, reduced peasant's drug cost simultaneously.
The object of this invention is to provide a kind of mixed herbicidal composite containing two careless ether and AC322140, it is characterized in that this weed killer herbicide is take two careless ether and AC322140 as main active ingredient, the mass ratio of two careless ether and AC322140 is 0.1～80: 0.1～80.Preferably the mass ratio of two careless ether and AC322140 is 1～40: 1～60, further preferably 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 ether and AC322140 is 1～85%, and 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, the 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 paddy field postemergence weed control, can effectively prevent and kill off various grassy weeds, broad leaved weed and sedge weed, particularly prevents and kill off annual gramineous weed, broad leaved weed and sedge weed.Especially can improve the 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 by two kinds of different mechanism, makes Weed Resistance produce Speed Reduction, greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Two careless ether is broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and AC322140 is to be mainly the weed killer herbicide of preventing and kill off sedge weed and broad leaved weed.Both can improve multiple grassy weed, broad leaved weed and sedge weed are had to preventive effect after mixing, thereby have extended the lasting period of medicament.
3, safe.Because its using dosage is under control, medicament is being improved under the prerequisite of drug effect, its safety to paddy field and succession crop is also improved.
Specific implementation method
Herbicidal combinations of the present invention is according to the former medicine correlation properties of two careless ether and AC322140, with and mechanisms etc., can be processed into the multiple formulations such as missible oil, suspending agent, aqueous emulsion, dry outstanding agent, water dispersion granule, wetting powder.The content of two kinds of active ingredients in Herbicidal combinations of the present invention does not limit to the scope in following examples.
