Abstract
The invention discloses a mixed herbicide containing glyphosate and bispyribac-sodium, belonging to the technology field of pesticides. The herbicide takes glyphosate and bispyribac-sodium as main effective ingredients, wherein the mass ratio of glyphosate to bispyribac-sodium is (80-98):(0.1-10). The invention also discloses application of the mixed herbicide to post-emergence weeding in a paddy field. The mixed herbicide has wide weeding spectrum through mixture of weed killers, so as to improve the weeding effect; the mixed herbicide has the advantages of having quick effect, long lasting period, thorough weeding effect, low residue, low toxicity, safety, environment protection and the like and having capability of delaying pesticide resistance of the herbicide, and has prominent prevention and control effect on grassy weeds, broad leaf weeds, sedge weeds in the paddy field such as barnyard grass, leptochloa chinensis, difformed galingale herb, Eleocharis yokoscensis, Sagittaria pygmaea, Rotala indica and Marsilea quadrifolia, and therefore, the mixed herbicide is high-quality post-emergence chemical herbicide.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of weed killer herbicide, be specifically related to a kind of mixed herbicide and application thereof with two careless ethers containing glyphosate.
Background technology
Glyphosate (Glyphosate), formal name used at school: N-((phosphonomethyl)) glycine, N-((phosphonomethyl)) amion acetic acid, is a kind of organophosphorus herbicide of wide effect type.It is that a kind of non-selective inner sucting conduction type cauline leaf is processed weed killer herbicide, when use, be generally made into isopropyl amine salt or sodium salt, its herbicide principle is mainly to suppress the activity of enol acetonyl shikimene phosphate synthase, thereby suppress the conversion of shikimene to phenyl alanine, cruel propylhomoserin and tryptophan, make synthetic being interfered of protein cause plant death.
Two careless ethers (bispyribac-sodium), having another name called salicylic acid Sulfadiazine Compound, is the pyrimidine Type salicylic acid broad-spectrum herbicide by the exploitation of Japanese combinatorial chemistry company, chemical name: 2, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of 6-.Two careless ether is a kind of pyrimidinylthiobenzoate herbicides, acetolactic acid enzyme inhibitor, work by the biosynthesis that stops branched-chain amino acid, applicable crops paddy rice, be mainly used in the postemergence weed control of direct seading rice, all effective to 1～7 leaf phase barnyard grass, prevent and kill off grassy weed, can prevent and kill off especially the barnyard grass of 1～7 leaf phase, double most of broad leaved weeds, some sedge weeds and the Stam F-34 controlled produces resistance barnyard grass.
Along with agriculture modernization development, peasant also uses in a large number high-tech product in agricultural production, a series of chemical products extensive uses such as biopesticide, Pesticidal composition, wherein most popular Pesticidal products is weed killer herbicide, the sales volume of weed killer herbicide comes foremost always in agricultural chemicals.Weed killer herbicide is wide in variety in the market, simultaneously application technology also require high, careless slightly in application, will there is the problems such as poisoning, herbicidal effect be bad.Weed killer herbicide is selected and improperly will directly be affected safety or the output of people or seedlings of cereal crops plant.Along with the development of weeding technology and the continuous appearance of weed killer herbicide, the many weeds in farmland are more and more difficult to kill.

The two careless ether suspending agents (commercially available) of test medicine: 100g/L, 360g/L gyphosate solution (commercially available), the preparation in embodiment 1～6.
Test method: the seed of quantitative barnyard grass is seeded in respectively in the Disposable paper cup of 9cm, sows 10～15 seeds in every glass, cultivate in illumination box, broadcast rear 3d, do to carry out soil spraying on composition spray in crawler type and process.After processing, in greenhouse, continue to cultivate, routine observation is respectively processed the preventive effect to weeds, weighs each weeds fresh weight after treatment after 30d, by the method that the nineteen sixties such as Sun Yunpei propose, calculates its toxicity regression curve and co-toxicity coefficient.Measurement result is as shown in table 1.
Co-toxicity coefficient classification: CTC is greater than 120 o'clock mixtures and has synergetic, and it is antagonism that CTC is less than at 80 o'clock, and CTC is summation action between 80～120.
Table 1: glyphosate and the indoor biometrics result of two different proportionings of careless ether to barnyard grass
Table 1 indoor biometrics result of the test shows, glyphosate is all greater than 120 with two composite rear co-toxicity coefficients of careless ether, and barnyard grass is had to obvious synergistic function.
2, field control effectiveness test
6 kinds of re-compounded binary herbicides in reagent agent: embodiment 1～6.
The two careless ether suspending agents (commercially available) of contrast medicament: 100g/L, 360g/L gyphosate solution (commercially available).
Control crop: paddy rice, rice seedlings was 3～5 leaf phases, grew fine, robust plant, without other damage by disease and insect.
Prevent and kill off object: grassy weed, broad leaved weed and the sedge weeds such as barnyard grass, moleplant seed, difformed galingale herb, needle spikesedge herb, short arrowhead, mexicana, four Ye Ping.
Test method: according to the area of experimental plot, accurately weigh good various medicaments, and be watered after dilution, utilize knapsack sprayer, carry out even spraying, the Fan spray head that sprinkler selection weed killer herbicide is special.When spraying, note liquid evenly to spray application in experimental plot the phenomenon of accomplishing there is no drain spray, spraying more.
After test, after medicine, 20d, 40d observe weeds death condition respectively, and the activity of weeding of more various medicaments.In addition, also to after medicine, in 1～15d, observe the growing state of crop, to investigate medicament, whether crop be had to poisoning.
The embodiments of the invention preparation weeding test effect 20d after 2(medicine that sees the following form) and table 3(medicine after 40d)
Table 2 field control effectiveness test result (20d after medicine)
Table 3 field control effectiveness test result (40d after medicine)
The security survey result of table 4 medicament to crop
From table 2, table 3 and table 4, can find out, the present invention, to rice safety, has significant preventive effect to weeds such as barnyard grass, moleplant seed, difformed galingale herbs, and synergy is remarkable, and instant effect, lasting period are long.
