Method for producing biological source herbicide

Abstract

The invention relates to a production method of a biological herbicide, belonging to the technical field of pesticide preparation preparation methods. Add biomass gasification liquid into the reaction kettle, then add special auxiliary agent according to the weight ratio of biomass gasification liquid 0.5-5%, stir evenly to obtain the product; the biomass gasification liquid is bamboo vinegar, wood Vinegar liquid or grass vinegar liquid; the special additives are SQ8208, HT201, EF8208 or EDW-518 special for paraquat, or EF8108, EDW-596 or Jixin-904 for glyphosate. The biogenic herbicide prepared by the above method has good herbicidal activity, belongs to the biocide herbicide, and has good environmental compatibility; it has high safety to agricultural products and is safe to humans; Promote plant growth; improve soil; low manufacturing price; the herbicidal effect of compound preparation with glyphosate, paraquat technical medicine or preparation is better than that of glyphosate and paraquat single agent.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of pesticide preparations, in particular to a production method of biological herbicides. Background technique [0002] Biomass gasification liquid is a brown liquid substance that is condensed at room temperature by the gas collected after pyrolysis of plant materials and their processing residues. It mainly includes bamboo vinegar, wood vinegar and grass vinegar. Bamboo vinegar is bamboo It is a by-product obtained by pyrolysis of processing residues at high temperature. Wood vinegar is a by-product obtained by pyrolysis of wood processing residues and fruit shells. Grass vinegar refers to herbs, crop straw and crop chaff. A by-product obtained from high temperature pyrolysis. In the process of processing bamboo, wood and straw into corresponding bamboo charcoal, charcoal and peat, because the by-product-biomass gasification liquid has not found its use and has become waste, many ma...

Problems solved by technology

In the process of processing bamboo, wood and straw into corresponding bamboo charcoal, charcoal and peat, because the by-product-biomass gasification liquid has not found its use and has become waste, many manufacturers do not take recycling treatment for it. It is directly discharged into the atmosphere, causing pollution to the environment, and it is easy to form local acid rain, which pollutes the environment, so it has become a technical problem in the modern production of bamboo charcoal, charcoal and peat.

At the same time, in recent years, few biopesticides have been developed into marketable varieties, which are far from meeting the needs of modern green and organic agricultural products, especially herbicides.

At present, in the herbicide market in my country, Mishengsheng herbicides are mainly 10% glyphosate water solution and 20-30% paraquat water solution. Due to the continuous increase in price and use cost of the latter, it is difficult for the domestic market to bear the high price And it is mostly used for export; although the price of the former is relatively low, it uses up to several kilograms per hectare due to its low activity, and the transportation cost continues to increase due to rising gasoline prices and the higher packaging price, so 10% glyphosate water The market of glyphosate is getting smaller and smaller, and more importantly, due to the long-term use of glyphosate, the soil compaction phenomenon is serious and the soil is continuously degraded, and the risk of its ecological environment is increasing
