Abstract
The present invention belongs to the field of agricultural chemicals. A compound provided by the present invention is composed of a triazinyl type herbicide using metribuzin and an amide herbicide type herbicide (butyl oxamine or ethyl oxamine). The compound is prepared by two kinds of agricultural chemical agents, such as emulsifiable solution and suspending emulsion, and has the advantages of providing safety for the present crops of soy beans, corn, etc. without residual herbicide damage to subsequently planted crops, enlarging wide application, preventing and removing annual monogenus and dicotyledonous weed at a time, reducing environmental pollution, providing easy use, etc., and the present invention is a favorable formula for weeding a stripping field between the soy beans and the corn.
Description
The invention belongs to pesticide field, specifically it is a kind of new herbicidal composition and preparation thereof.Said composition contains known piperazine humulone (metribuzin) and a kind of herbicide butachlor (butachlor) or Acetochlor (acetochlor) that is selected from amide-type with activity of weeding.
The piperazine humulone is the weed killer herbicide of Soybean and Other Crops based on soil treatment, but is guaranteeing under the prerequisite of effective management of weeds, employed dosage to the safety of soybean relatively poor (referring to the chief editor of medicine inspecting institute of the Ministry of Agriculture " newly organized agricultural chemicals handbook P531-534).On the contrary, if the dosage of reduction piperazine humulone does not reach the good result (light soil soybeans dosage is no more than 28 gram/mus) to weeds again.The piperazine humulone longevity of residure is short than atrazine, is difficult for being stranded in environment.1981-1987 Fank, people such as R are to the monitoring of U.S. Sydenhan River river (30-50 time/year), and the result is: the percentage that the piperazine humulone measures is 2-7%, and atrazine (atrazine) is up to 89-100% (Weed Abstracts 40:2484).Therefore improve the utilization rate of piperazine humulone, the mixture that substitutes atrazine at corn field uses, and is significant in environmental protection.Chinese patent CN1154201A discloses a kind of corn field, soybean field herbicide, wherein Acetochlor/piperazine humulone /=1/6-1/2, but piperazine humulone content is too high, easily soybean is produced poisoning and uneconomical material benefit.
The object of the present invention is to provide a kind of piperazine humulone and amide herbicide composition, it both can guarantee good preventive effect, can reduce the dosage of piperazine humulone again, improve the safety of crop, enlarge and kill the grass spectrum, weeds such as lady's-grass, lamb's-quarters, piemarker there is synergistic effect, and can be used as the use of corn field soil treatment type weed killer herbicide.Below be described in detail main contents of the present invention.

Annotate: the proportioning of fourth piperazine missible oil is 2: 1
4, piperazine humulone and butachlor or Acetochlor are made mixture, more convenient in the use.Because the former medicine of piperazine humulone is insoluble in common organic solvents, be mixed with missible oil and acquire a certain degree of difficulty, the past generally is processed into wetting powder or dry suspending agent.But we find that piperazine humulone solvability in the compound solvent of some specific solvent such as the fragrant same clan and alcohols can improve greatly, can satisfy the requirement of preparation piperazine humulone and amide-type herbiciding composite dose (missible oil).The former medicine of piperazine humulone belongs to water insoluble solid again, and it and acetamide-group herbicides crude oil also are suitable for pesticides new formulation-suspension emulsion suspoemulsions) process or prepare.
5, good in economic efficiency.About 5～6 yuan of mu usefulness fourth piperazine or ethysine mixture cost, input-output ratio is: 1: 10～15.
Through internal authority World Patent Index (Britain Derwent), Chinese patent literature database, Weed Abstracts and U.S. chemical abstract (CA) retrieval find no all that piperazine humulone and butachlor or Acetochlor are used with and the report of mixture, therefore the present invention belongs to initiative both at home and abroad according to novelty is arranged.

Piperazine humulone and amide herbicide composition preparation are applicable to the weed control on multiple kinds of crops ground, as following crop: soybean, corn, peanut, potato, tomato, sugarcane, clover, asparagus, coffee etc., be particularly useful for soybean and corn intercrop ground, replenished China does not have fine herbicide at this type crop field blank.
Biological Examples
1, synergistic effect
The effect of the mixture of piperazine humulone and acetamide-group herbicides butachlor or Acetochlor, no matter when it all greater than the summation of the effect of single time spent of each active ingredient, promptly has synergistic effect to the effects of weeds.Method of discrimination adopts the abundant method of Sun Yun (referring to Zhang Ruiting " using with and mixture of agricultural chemicals ", Chemical Industry Press, 1987, P26～28), and co-toxicity coefficient is a summation action near 100, is synergistic effect greater than 100 obviously, is antagonism less than 100 significantly.From table 3～5 as seen, ethysine, fourth piperazine mixture are 112.96～143.7 to the co-toxicity coefficient of lady's-grass, lamb's-quarters, piemarker, and synergistic effect is promptly all arranged.
2, to the safety of crop
Safety to crop is estimated with Cobly method [referring to Zhang Fayan " herbicide mixture and interaction ", agricultural chemicals collected translation, 1985,7 (3)] and selectivity index (referring to the P413 of south China agricultural college " chemical protection of plant "～415).If mixture has antagonism or selectivity index more than or equal to 2 to crop, illustrate that mixture is safe to crop, otherwise be unsafe.As seen from Table 1, ethysine mixture E＞Eo, mixture has antagonism to soybean and corn.From table 6, table 7 as seen, medicament all more than or equal to 2, illustrates that it is safe that medicament uses to the selectivity index of soybean or corn and weeds on soybean and corn.

3, field control effectiveness test
45% ethysine, fourth piperazine missible oil use, have crop safety Beijing area soybean and corn field, enlarge and kill the grass spectrum, preventive effect is good, can effectively prevent and kill off advantages (referring to table 8 and table 9) such as the annual single, double cotyledon weeds in field, filled up the blank of soybean, corn intercrop ground no fine herbicide, the initial stage on probation just is subjected to the welcome of peasant household deeply.Because half life period of piperazine humulone is about 28 days, to succession crop can not produce poisoning (referring to the chief editor of medicine inspecting institute of the Ministry of Agriculture " newly organized agricultural chemicals handbook P532), and acetamide-group herbicides are shorter than the half life period of piperazine humulone, more do not have residual drug injury problem.
