General formula of the present invention (I) dibenzo-1,3-two oxa-s-cyclooctane-2-carboxylic acid amine ester cpds has weeding activity, uses behind Miao Qianmiao and can effectively control single broadleaf weed.
The present invention comprises that also with general formula (I) compound be the herbicidal composition of active ingredient.The weight percentage of active ingredient is between 1-99% in this herbicidal composition.Comprise also in this herbicidal composition that agricultural goes up acceptable carrier.
Compound of the present invention can preparation form be administered on soil or the blade face.This compound is dissolved in the carrier usually or is mixed with preparation so that be easier to disperse when using as weedicide.For example: these chemicals can be made into wettable powder or missible oil.In these compositions, add a kind of liquid or solid carrier at least, and when needing, can mix suitable tensio-active agent.
Other embodiments of the present invention are method of controlling weeds, and this method comprises herbicidal composition of the present invention is imposed on the surface of growth medium of the places of described weeds or described weeds or described weeds.Usually the comparatively suitable significant quantity of selecting is that per hectare 10 restrains 5000 grams, and preferred significant quantity is that per hectare 100 restrains 2000 grams.
Use for some, can in herbicidal composition of the present invention, add one or more other weedicide, can produce additional advantage and effect thus.
Compound of the present invention both can use separately also can be mixed together use with other known sterilant, sterilant, plant-growth regulator or fertilizer etc.
Should be clear and definite be in claim of the present invention institute restricted portion, can carry out various conversion and change.
Embodiment
The following example, living test are tested the result and be can be used to further specify the present invention, but do not mean that restriction the present invention.
Synthetic example
Synthesizing of compound 1:
Under the ice-water bath condition, oxalyl chloride (2.6 grams, 21 millis rub) is joined acid (A) (3.0 grams, 13 millis rub) and CH
2Cl
2In the mixture of (20 milliliters), drip a DMF then.After reaction mixture at room temperature stirs and spends the night, remove target compound (B) 3.2 grams that desolvate and obtain faint yellow solid by underpressure distillation.
Under the ice-water bath condition will on go on foot the CH that product (B) (0.2 gram) joins azanol (0.1 gram) and triethylamine (0.2 restrains)
2Cl
2In (10 milliliters) solution.Reaction soln at room temperature stirred 3 hours, evaporate to dryness, and residuum extracts with ethyl acetate (100 milliliters), organic layer water, 1%NaHCO
3Anhydrous MgSO is used in the aqueous solution and saturated common salt washing
4Dry.Obtain buttery 0.15 after the underpressure distillation and digest compound 1.
Other compounds in the table 1 can make by above similar method.
Give birth to and survey example
With the former medicine of acetone solution, by design dosage, join in the certain water gaging that contains tensio-active agent, make certain density preparation.Spray with mobile belt atomizer.The examination material is put in spraying rolling in the cupboard and is with, and mobile shower nozzle is sprayed onto medicament on the examination material with the covering of the fan Sprayable through examination material top, identical on nozzle and the common field spray device.Roll band and will try material and shift out outside the cupboard, place loft drier dry.
Test before the seedling: after planting carry out, test compound sparges soil surface, handles and is placed on the greenhouse, waters then; Test behind the seedling, seed germination also grew 10-21 days, made the examination material that has a series of growing stages before the processing, selected size, the consistent examination material of growing stage then, handled, and handled to be placed on the greenhouse and to water.The examination material with compound treatment does not compare.The examination material is broadleaf weed youth-and-old-age, piemarker and Cassia tora; Monocotyledon weed barnyard grass grass, dog tail and lady's-grass.
Examination material after the spraying drying places the greenhouse.Test is from the top water spray before the seedling, and test is poured water from the bottom and kept 48 hours so that water does not touch the blade face behind the seedling.
Handling the back investigated in 4 weeks.Inhibiting rate is total effect of various infringements such as chlorosis, withered spot, retarded growth or the calcination of leaf angle, obtains the result with blank after relatively.Partial test the results are shown in Table 2.
