Abstract
The invention belongs to the field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicide composition containing bispyribac-sodium and benthiocarb. The herbicide composition adopts the bispyribac-sodium and the benthiocarb as main active components, the weight ratio of which is 1 to 99:1 to 99. The herbicide composition can be added with different surfactants, thickening agents, solvents, solid fillers or the like to become a variety of agents, such as emulsifiable concentrate, suspending agent, water-dispersible granules and wettable powder. The herbicide composition can prevent and get rid of gramineous weeds, broadleaf weeds and cyperaceous weeds in paddy fields, and compared with single agents, the herbicide composition delays the resistance of weeds under the premise that the effect is enhanced, has a broad weeding spectrum and long persistence, is safe for rice and next-stubble crops, and therefore is an ideal paddy field herbicide.
Description
Technical field
This patent belongs to pesticide field, and especially the weed killer herbicide field relates to a kind of mixed herbicidal composite that contains two careless ethers and benthiocarb.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:
Benthiocarb has another name called benthiocarb, and weed eradication is red, and Benthiocarb removes the field green bristlegrass.Chemical name: S-[(4-chlorphenyl) methyl] diethyl thiocarbamate, structural formula is:
This weed killer herbicide is a carbamates selectivity inner sucting conduction type soil processing herbicide, can be absorbed by root of weeds and young shoot, and particularly young shoot is transferred in the plant corpus after absorbing, and growing point is had very strong inhibitory action.Benthiocarb hinders AMS and protein synthesis, and the mitosis of plant cell is also had the strong inhibition effect, thereby the weed seed that causes sprouting is withered with the weeds at the initial stage of sprouting.It is faster than paddy rice that the barnyard grass grass absorbs the speed of conduction benthiocarb, and the speed of degradation in vivo benthiocarb is slower than paddy rice, and this is to form optionally physiological foundation.This type of weed killer herbicide can be rapidly by adsorption by soil, thereby little with the leaching property of moisture, generally is distributed in soil layer 2 centimeters.The suction-operated of soil has reduced the loss that is caused by evaporation and photodissociation.Half life period in soil is 2-3 week under the ventilation good condition, and anaerobic condition is next to be the 6-8 month.Can be by soil microbial degradation, the dechlorination benthiocarb that is formed by edaphon under the anaerobic condition can suppress paddy growth consumingly.
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.
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 benthiocarb; This Herbicidal combinations can not only improve the preventive effect 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 benthiocarb, it is characterized in that this Herbicidal combinations is main active ingredient with two careless ethers and benthiocarb, the mass ratio of two careless ethers and benthiocarb is 1～99: 1～99.The mass ratio of preferred two careless ether and benthiocarb is 1～50: 1～70, and the mass ratio of further preferred two careless ethers and benthiocarb is 1～40: 1～30, and the mass ratio of most preferably two careless ethers and benthiocarb is 1～20: 1～10.
In mixed herbicidal composite, the two quality percentage composition in Herbicidal combinations of two careless ethers and benthiocarb 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 benthiocarb; 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 grassy 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 the part broad leaved weed is had preventive effect, and it has good preventive effect to annual gramineous weed, and benthiocarb is mainly to be the weed killer herbicide of annual gramineous weed.Both can improve the preventive effect of the preventive effect to multiple grassy weed, broad leaved weed and sedge weed, particularly annual gramineous weed, broad leaved weed and sedge weed, thereby prolong the lasting period of medicament after mixing.
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.
