Abstract
The present invention relates to a weedicide. The raw material composition of said weedicide includes (by wt%) 0.01-10% of azafenidin, 40-95% of isoproturon, 0.2-20% of conventional adjuvant and the rest is filling material. Besides, said invention also provides its preparation method and concrete steps.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, especially a kind of weed killer herbicide of being prepared by azoles humulone and isoproturon belongs to technical field of pesticide.
Background technology
The chemical name of azoles humulone (carfentrazone-ethyl) is: (RS)-and 2-chloro-3-[2-chloro-5-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxidation-1,2, the 4-triazol-1-yl)-and the 4-fluorophenyl] propionic acid, have another name called the spirit of going out soon (U.S. FMC Corp. trade name), this product is U.S. FMC Corp. development product, is a kind of to broad leaved weed weed killer herbicide efficiently, and spraying the back has the removing activity that is exceedingly fast to weeds.Active general when the azoles humulone is used for cornfield herbicidal separately, and invalid to grassy weed.
The chemical name of isoproturon (isoproturon) is: 3-is right-and cumenyl-1, the 1-dimethyl urea, this product is by at first being succeeded in developing in 1972 by German Hoechst AG, a kind of phenyl ureagroup herbicides, weeds absorb the back and suppress photosynthetic normal function and kill weeds, and there are companies such as Jiangsu Chang Long, Suzhou Hua Yuan in domestic present manufacturing enterprise.Isoproturon can kill most standing grain herbaceous weeds, but to part broadleaved herb poor effect, so use limitation is arranged.
Summary of the invention
The technical problem to be solved in the present invention is exactly isoproturon and azoles humulone existing not wide and agricultural this higher situation of careless scope of killing when using separately, develops a kind of compound weed killer herbicide, and is harmless to crops, and environmentally friendly, adaptable weed killer herbicide.
The present invention includes two kinds of active ingredients of azoles humulone and isoproturon, the weight content of each component is: azoles humulone 0.01-10%, isoproturon 40-95%, conventional pesticide auxiliary agent 0.2-20%, all the other are filler.
The preferred weight content of each component is: azoles humulone 0.02-10%, isoproturon 40-80%, and conventional pesticide auxiliary agent 2-10%, all the other are filler.
The preferred weight content of each component is: azoles humulone 0.5-10%, isoproturon 40-70%, and conventional pesticide auxiliary agent 3-8%, all the other are filler.
Described conventional auxiliary agent is selected from one or more the mixture in surfactant, suspension emulsion, the diffusant.Wherein, pesticide surfactant can be selected bleeding agents such as BX, the fragrant APEO of LS nonyl, agricultural newborn BY, 885 series of products and various organic silicon surfactant, BD-3701 for use; Agricultural chemicals suspension agent normally is made up of active ingredient, dispersant, thickener, defoamer, antifreezing agent and water etc., comprises aqueous suspension agent commonly used, colloidal suspending agent, concentrated suspension; The agricultural chemicals diffusant can be selected NNO or MF6 dispersant with high efficiency etc. for use.
Described filler is the mixture of one or more arbitrary proportions in kaolin, bentonite, old soil, diatomite, the white carbon black etc.
Adopt said components, the present invention can be mixed with various formulations such as pulvis, granule.
As being mixed with " azoles humulone+isoproturon " wetting powder of 70%, its dosage is: 60-120 (g/ mu).
The present invention carries out azoles humulone and isoproturon composite, improves the activity of using separately separately, have tangible spread spectrum synergistic effect, but a drug is killed multiple weeds in preventing and kill off.Because its active raising can obviously reduce consumption, thereby play the safety that improves environment and food, favourable fall this, volume increase, tally with the national condition.
Embodiment
Embodiment 1:
The weight content of each component is: azoles humulone: 0.4%; Isoproturon: 69.6%; Pesticide surfactant BX:3%; Pesticide surfactant LS:2%; The agricultural chemicals dispersing agent NNO: 1.5%, all the other are supplied for bentonite, make 70% wetting powder weed killer herbicide.
Embodiment 2:
The weight content of each component is: the azoles humulone: 0.5%, and isoproturon: 69.5%, pesticide surfactant: BX3%, pesticide surfactant LS:1%, pesticide surfactant 885:1.5% is added into 100% with kaolin, makes 70% granular herbicidal agent.
Embodiment 3:
The weight content of each component is: the azoles humulone: 0.3%, and isoproturon: 69.7%, pesticide surfactant: 1, APEO 3%; 2, sulphur ox glue 2%; 3, diffusion agent N 2%; 4, white carbon black 1%; 5, add to 100% with deionized water, make 70% suspension emulsion.
Following table is the experimental data table of comparisons of embodiment 2 described 70% azoles humulone+galloping horses of isoproturon wetting powder, three kinds of situations of not medication.
Unit: strain/m
2
| Processing method | 70% azoles humulone+isoproturon wetting powder | Galloping horse | Not medication |
| Dosage (g/ mu) | 100 | 40 | / |
| The amur foxtail residual quantity | 1.2 | 1.1 | 30 |
| Preventive effect (%) | 96 | 96.3 | / |
| The residual number of clearvers | 0 | 25 | 27 |
| Preventive effect (%) | 100 | 7.4 | / |
| Integrated control effect (%) | 98.0 | 51.85 | / |
Above-mentioned test result proves, 70% wettable divides the weed killer herbicide (be azoles humulone+isoproturon of the present invention with 0.5: 69.5 weight proportion) of pulvis to have stronger activity of weeding, to the wheatland malignant weed, amur foxtail, clearvers integrated control effect obviously are better than galloping horse up to 98%.In addition, through facts have proved, azoles humulone+isoproturon also has same effect at 1.0: 50.Above percentage is weight ratio.
