Abstract
The present invention relates to herbicide, and is especially one kind of re-compounded Langdu preventing and killing herbicide. The re-compounded herbicide is re-compounded with 2, 4-D butyl 50-94 wt%, 3, 5, 6-tichloro-2-pyridyl oxyacetic acid 5-50 wt%, gelatin 0.5-2 wt% and sodium octodecyl sulfonate 0.5-2 wt%, and through mixing the materials through stirring, bottling and sealing to obtain the product. The present invention has the advantages of specificity of killing Langdu, easy operation, small use amount, low toxicity, low residue and high efficiency.
Description
Technical field
The present invention relates to a kind of complex weedicide, specifically relate to a kind of complex weedicide of Langdu preventing and killing.
Background technology
Cause in the five big factors of grass-land deterioration in China, poisonous weedsization have been the factor on the second largest serious harm grassland after desertification.3636.9 ten thousand hm in Qinghai Province
2In the native pasture area, deteriorate grassland area 530 * 10
4Hm
2, malicious weeds type deteriorate grassland is 262.11 * 10
4Hm
2, account for 49.5%, wherein root of langdu generation area 73.94 * 10
4Hm
2, account for 28.2% of malicious weeds type deteriorate grassland area.The stellera Thymelaeceae, be commonly called as " steamed bun flower ", be one of the most serious pernicious poisonous weeds of present Qinghai Province natural meadow harm, its growth potential is strong, and breeding is fast, and summer is flourishing, strive space, soil, moisture, nutrition etc. with good forage, suppressed the growth of good forage, the good forage ratio is descended, malicious weeds are increased.Not edible grass and poisonous weeds replace good forage gradually becomes the social dominance kind, and large-area meadow has lost value, causes grass poultry contradiction to be on the rise; In addition, because root of langdu complete stool is poisonous, cattle and sheep are easily eaten by mistake and cause death.The large tracts of land of the root of langdu has been accelerated the speed of the reverse succession in meadow, and the ecosystem is vicious circle, and the deteriorate grassland difficulty of governance is strengthened.
Langdu preventing and killing mainly is with single glyphosate, 2 at present, 4-D, make its medicament such as grand, and existing patent has formerly done to remove the invention of root of langdu aspect, but these medicament medication targets are poor, bigger to the injury of other broad-leaved herbages, destroyed the bio-diversity on grassland, caused grassland herbage single, cause the livestock nutrition imbalance, hindered Developing of Animal Industry.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiency that prior art exists, and a kind of compound chemical weed killer herbicide---Recompounded Langdu preventing and killing herbicide of special-purpose Langdu preventing and killing of high selectivity is provided.
Recompounded Langdu preventing and killing herbicide of the present invention is to be made by following raw materials in percentage by weight:
2,4-D butyl ester 46-94%;
3,5,6-trichloro-2-pyridyl fluoroacetic acid 5-50%;
Adjuvant is: gelatin 0.5-2%; Octadecyl sodium sulfonate 0.5-2%;
Preparation technology is: earlier with 2, the 4-D butyl ester adds in the container, slowly adds 3,5 again, 6-trichloro-2-pyridyl fluoroacetic acid, and the limit edged stirs, and adds adjuvant gelatin and octadecyl sodium sulfonate at last, and fully mixing is bottled, and sealing promptly gets product.
Recompounded Langdu preventing and killing herbicide of the present invention has following beneficial effect compared with prior art: because Recompounded Langdu preventing and killing herbicide of the present invention mainly is to disturb plant hormone balance and metabolism of nucleic acid, make nucleic acid and the growth hormone of plant excessive, cause the plant teratogenesis, cause growing point enlargement, distortion; Inhale in the weed killer herbicide of the present invention, conductivity is strong, medicament can cause the root enlargement rapidly from being subjected to the medicine position to import root into by vascular bundle, reserve substance consumption is too much, and the root of langdu can't be survived the winter, root all rotted, can not turn green next year.
The weed killer herbicide of other Langdu preventing and killing of using on the present invention and the market is compared; this weed killer herbicide has the characteristics of high selectivity, efficient, safety, low-residual; preventive effect can reach more than 95%; not only the root of langdu there is good preventive effect; and, protected the bio-diversity on grassland to other good forage safety.It is that a kind of economy, effective and suitable large tracts of land are gone out except that the weed killer herbicide of the root of langdu, can control the harm of the root of langdu within a short period of time, improve the quantity and the ratio of good forage in the plant community of meadow, the output of meadow good forage and quality are greatly enhanced.Can obviously set up useful plant community, thereby reach restoration of the ecosystem, control the target of the root of langdu for a long time, ensure the stable of meadow bio-diversity, promote the sustainable development of animal husbandry economy and ecotope.
The present invention has following advantage:
1, strong this medicament target of selectivity is single-minded, and is only effective to the root of langdu, harmless to other plant, thus protected the bio-diversity on meadow, do not destroy structure of plant community.
2, be convenient to operate this medicament and adopt conventional, conventional spray, need not use special chemical sprayer tool.
3, the low per hectare dosage of dosage is no more than 900ml, has reduced cost.
4, low toxicity, this medicament of low-residual half life period are no more than 50 days.
5, efficient, quick-acting dispensers promptly reacted after 2 hours, and the root of langdu begins here to wither, and growth is suppressed, and preventive effect reaches more than 95%.
