Abstract
The invention belongs to the field of pesticides, and relates to a mixed herbicide composition containing bispyribac-sodium and prometryn. The herbicide composition adopts the bispyribac-sodium and the prometryn as main active components, the weight ratio of which is 0.1 to 99:0.1 to 99. The herbicide composition can prevent and get rid of annual 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
The invention belongs to pesticide field, especially the weed killer herbicide field, relate to a kind of mixed herbicidal composite containing two careless ether and prometryn.This Herbicidal combinations application paddy field postemergence weed control has remarkable result.
Background technology
Two careless ether, have 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:
Prometryn, have another name called and flutter climing to the greatest extent, mows good, and prometryn.Chemical name: 4,6-bis-isopropylamine base-2-methyl mercapto-1,3,5-triazines, structural formula is:
This weed killer herbicide is the selectivity inner-adsorption conduction-type herbicide, can be from root absorption, also can infiltrate in body from cauline leaf, be transported to inhibited photosynthesis in green blade, poisoning weeds chlorosis is withered dead gradually, the performance herbicide effect, its selectivity is relevant with the difference of plant ecological and biochemical reaction, and best to the weeds preventive effect of firm sprouting, prometryn is water-soluble lower, after dispenser, can be adsorbed in 0-5cm table soil by soil clay particle, form the medicine layer, contact medicament when weed germination is unearthed, lasting period 20-70 days, nonirrigated farmland is long than paddy field, longer in clay.
At present, herbicide for paddy field is limit by crop safety, herbicide spectrum is also limited, uses separately a kind of weed killer herbicide single dose can not control completely effectively the generation of paddy field weed, moreover the weed killer herbicide consumption is excessive or dispenser is inhomogeneous also easily causes the residual hazard to this season crop or succession crop.Therefore, the present invention selects the two careless ether of pluses and minuses complementation and prometryn to be made into combination agent to use, so both reduced the consumption of medicament, obviously improved herbicidal effect, has also avoided this season is done to the deposits yields poisoning and to the possibility of succession crop generation residual hazard.
Summary of the invention
The present invention is according to the present situation of current paddy field herbicide after seedling, and after the paddy field seedling weeds a situation arises, provide a kind of by two careless ether and the composite binary mixed herbicidal composite of prometryn, this Herbicidal combinations can not only improve the preventive effect to weeds, and, to when stubble and succession crop safety, reduced drug cost simultaneously.
The purpose of this invention is to provide a kind of mixed herbicidal composite containing two careless ether and prometryn, it is characterized in that it is main active ingredient that this Herbicidal combinations be take two careless ether and prometryn, the mass ratio of two careless ether and prometryn is 0.1～99: 0.1～99.The mass ratio of preferably two careless ether and prometryn is 1～40: 1～60.
In Herbicidal combinations of the present invention, the mass ratio of two careless ether and prometryn more preferably 1～30: 1～20, and the mass ratio of two careless ether and prometryn most preferably is 1～10: 1～10.
In mixed herbicidal composite, the two quality percentage composition in Herbicidal combinations of two careless ether and prometryn 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 prometryn, except two kinds of active ingredients, can also add the auxiliary agent allowed on the agricultural chemicals such as different surfaces activating agent, thickener, solvent or solid packing, be processed into the multiple formulations such as missible oil, suspending agent, water dispersion granule, wetting powder.
This Herbicidal combinations can delay Weed Resistance with respect to single dose under the prerequisite that has improved drug effect, and 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 especially preparation 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 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 the broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and prometryn is to be mainly the weed killer herbicide of preventing and kill off broad leaved weed.After both mix, can improve the preventive effect of grassy weed, broad leaved weed and sedge weed, particularly can significantly improve the preventive effect of annual gramineous weed, broad leaved weed and sedge weed, thereby extend 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.
