Abstract
The present invention discloses the basic components of one kind of multiple-purpose farm chemical, composite tar-acetic acid emulsion. It contains tar including coal tar, wood tar or their mixture not less than 20% as main effective components and acetic acid not less than 9% as synergist. Tar is emulsified with emulsifier and dissolved with ethanol and the emulsion is diluted with water before use. The farm chemical has the functions of inhibiting virus, killing molds and regulating plant growth and is low in toxicity, high in efficiency, low in residue and suitable for use in development of modern agriculture.
Description
The invention belongs to technical field of organic chemistry, is a kind of multipurpose agricultural chemicals-tar-acetic composite emulsion specifically.
Agricultural chemicals is the medicament that is used to prevent and treat the biological epidemics of agricultural and regulates crop growthing development, and the chemical pesticide that uses mainly contains three major types: insecticide, bactericide, weed killer herbicide by the purposes branch now.They are playing very enormous function aspect the developing agricultural production.Along with the continuous development of science and technology, modern agriculture more needs efficiently, low toxicity, less-persistent pesticide.
The present invention's purpose is just in order to adapt to the needs of modern agricultural development, and the multipurpose agricultural chemicals-tar-acetic composite emulsion of a kind of efficient, low toxicity, low-residual is provided.
The object of the present invention is achieved like this: a kind of multipurpose agricultural chemicals-tar-acetic composite emulsion, its former medicine is a tar, i.e. coal tar, wood tar or their mixture.Its content 〉=20%.Its synergist is an acetic acid, its content 〉=9%.Because tar is oily liquids and water insoluble, be not easy to the peasant and use, so will add emulsifier, it is modulated into the liquid preparation-missible oil of homogeneous phase, so that in use can in water, be dispersed into uniform emulsion automatically during thin up.Simultaneously owing to contain in tar that adopts among the present invention and the acetic acid and can suppress virus, kill mould, regulate the various organic compounds of crop growthing development, and these raw materials come from the natural materials in the Nature, be not synthetic, so just can reach purpose of the present invention like this.
Adopt the present invention will obtain following effect:
1. agricultural chemicals, multiple function and effect have enlarged use and accommodation.
2. help reducing public hazards, the protection ecological balance.
3. the preparation high concentration is convenient to packed and transported, low concentration then during use, cost
Low, convenient.
Below will the present invention is further illustrated by principles of chemistry analysis and applicable cases.
Principles of chemistry simple analysis:
Former medicine---tar: comprise coal tar, wood tar, they are oily products that coal, timber obtain through destructive distillation, and they all are a kind of extremely complicated mixtures.Wherein: the key component of coal tar is arene compound and heterocyclic compound.Therefrom separablely go out phenol, naphthalene, anthracene, coumarone resin, and pyridine, quinoline and homologue thereof etc. are arranged.Wood tar mainly contains phenols organic acid and hydro carbons.
Synergist---acetic acid.Because the most of active ingredient in the former medicine only could keep its chemical stability under acid condition, more effectively play a role, a kind of organic acid of acetic acid itself also is a kind of medicament simultaneously.So with acetic acid is very suitable and effective.
More than in the said compound, facts have proved to have and suppress having of viral effect: phenols, acetic acid.What have bactericidal mould proof effect has: phenols, naphthalene, anthracene, acetic acid.What have insecticidal effect has: phenols, naphthalene, quinoline.Have having of coordinate plant growth growth: pyridines.
Emulsifier---generally adopt acid emulsifier.Its reason is: water insoluble because tar is oily, and can not under this high concentration, directly be used in crops, so must add homogeneous liquid preparation---the missible oil that emulsifier is made into emulsibility, good stability.When needs use, to be diluted as long as add water, it will automatically be evenly dispersed in the water, forms the emulsion of oil-in-water formula.So both be convenient under high concentration, pack and transport, and be convenient to again under low concentration, use.
Solvent---what generally adopt is ethanol, and its effect is that missible oil is diluted slightly, and wherein each kind of raw material mixed more fully.Itself is exactly a kind of organic medicament, also is a kind of bleeding agent that promotes plant absorbing.
The effect example:
The tar-acetic composite emulsion that contains wood tar 20% dilutes 800 times, is used for edible mushroom Bag Material spice, only needs the sterilization in a hour of 100 degree, can make Bag Material significantly reduce the generation of mould, and improve output.
The tar-acetic composite emulsion that contains wood tar 20% dilutes 600 times.Prosperous long-term and per 8 days of the setting phase cucumber is carried out foliage-spray one time, and its cucumber mosaic incidence of disease is 0, and effect of increasing production is obvious.
With the tar-acetic composite emulsion that contains tar 20% gray mold, the downy mildew of tomato, custard squash are prevented and treated, positive effect is arranged.The mildew that mandarin tree is taken place because of overcast and rainy low temperature has the better prevention effect.Virus disease to watermelon, tomato, capsicum also has positive effect simultaneously.
