Abstract
The invention belongs to the field of pesticides, and relates to a mixed herbicide composition containing bispyribac-sodium and cyhalofop-butyl. The herbicide composition adopts the bispyribac-sodium and the cyhalofop-butyl as main active components, the weight ratio of the bispyribac-sodium and the cyhalofop-butyl is 1 to 99:1 to 99, and the herbicide composition is mainly applied to postemergence weeding in paddy fields, and particularly can prevent and get rid of annual gramineous weeds, broadleaf weeds and cyperaceous weeds in paddy fields. Compared with single agents, the herbicide composition delays the resistance of weeds under the premise that the pesticide effect is enhanced, has a broad weeding spectrum and long persistence period and is safe for rice and next-stubble crops.
Description
Technical field
This patent belongs to pesticide field, and weed killer herbicide field especially relates to the mixed herbicidal composite of two careless ethers and cyhalofop-butyl.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.
Cyhalofop-butyl has another name called a thousand pieces of gold, chemical name: (R)-2-[4 (4-cyanic acid-2-fluorophenoxy) phenoxy group]-butyl propionate, structural formula is:
This weed killer herbicide is only in the fragrant phenoxy propionic acid class weed killer herbicide paddy rice to be had the kind of tight security, and is the same with such other kinds, also is interior suction conductivity weed killer herbicide.Blade and leaf sheath by plant corpus absorb, and the phloem conduction accumulates the meristem zone in plant corpus; Resist acetyl-CoA carboxylase (ACCase), fatty acid is synthesized stop, the growth division of cell can not normally be carried out; Film system etc. contains the fat structural deterioration, causes plant dead at last.It is slower to be absorbed into weeds death from cyhalofop-butyl, generally needs 1-3 week.The symptom of weeds after dispenser is following: the tender shoots atrophy of four leaf phases causes death.The Lao Ye of two leaf stage changes minimum, keeps green.
At present; Herbicide for paddy field is limit by crop safety; It is also limited to kill the grass spectrum, use the agent of a kind of weed killer herbicide list can not control the generation of paddy field weed completely effectively separately, moreover the weed killer herbicide consumption is excessive or the inhomogeneous residual hazard that also causes easily this season crop or succession crop of dispenser.Therefore; The present invention selects complementary two careless ether of pluses and minuses and cyhalofop-butyl to be made into the combination agent use; So both reduced the consumption of medicament, obviously improved herbicidal effect, and also avoided this season is done the deposits yields poisoning and succession crop produced the possibility of residual hazard.
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 cyhalofop-butyl; This Herbicidal combinations can not only improve the preventive effect to weeds, and to when stubble and succession crop safety, has reduced drug cost simultaneously.
The purpose of this invention is to provide a kind of mixed herbicidal composite that contains two careless ethers and cyhalofop-butyl, it is characterized in that this Herbicidal combinations is main active ingredient with two careless ethers and cyhalofop-butyl, the mass ratio of two careless ethers and cyhalofop-butyl is 1～99: 1～99.The mass ratio of preferred two careless ether and cyhalofop-butyl is 1～40: 1～60, and further the preferred mass ratio is 1～30: 1～20, and most preferably mass ratio is 1～10: 1～10.
In mixed herbicidal composite, the two quality percentage composition in Herbicidal combinations of two careless ethers and cyhalofop-butyl 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 cyhalofop-butyl; Except two kinds of active ingredients; Can also add the auxiliary agent that allows on the agricultural chemicals such as different surfaces activating agent, thickener, solvent or solid packing, be processed into multiple formulations such as missible oil, suspending agent, water dispersion granule, wetting powder.
This Herbicidal combinations can delay the weeds resistance with respect to single agent under the prerequisite that has improved drug effect, herbicidal spectrum is wide, and the lasting period is long, enough prevents and kill off paddy field annual gramineous weed, broad leaved weed and sedge weed, and to paddy rice and second stubble crop safety.Herbicidal combinations of the present invention can be used for preparing the weed killer herbicide of paddy field postemergence weed control; Can be used in preparation especially and prevent and kill off the weed killer herbicide of various annual weed and perennial weed, especially can prepare the weed killer herbicide of preventing and kill off grassy weed, broad leaved weed and sedge 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 cyhalofop-butyl mainly is to prevent and kill off barnyard grass grass, grassy weeds such as moleplant seed.After both mixed, the preventive effect of preventive effect, particularly annual gramineous weed, broad leaved weed and sedge weed that can improve grassy weed and broad leaved weed and sedge weed was particularly remarkable, thereby had prolonged the lasting period of medicament.
3, safe.Medicament of the present invention is under the prerequisite that has improved drug effect, and its safety to paddy field and succession crop also is improved.
