| 摘要 |
The invention refers to agriculture, namely to plant pest control means. The plant spraying pesticide, according to the invention, comprises copper ferro(III)-hexacyanoferrate(II), dispersed bentonite and fusel oil in the following component ratio, g/L:copper ferro(III)-hexacyanoferrate(II)�3à5dispersed bentonite���10à15fusel oil����5à10.The process for preparation of the plant spraying pesticide includes preparation of copper ferro(III)-hexacyanoferrate(II) by preliminary introduction of the dispersed bentonite into the aqueous-alkaline solution of the sodium or calcium ferro(III)-hexacyanoferrate(II) concentrate, heating of the obtained suspension with subsequent addition of a stoichiometric quantity of copper sulphate, as well as mixing with fusel oil. In the process there is used sodium or calcium ferro(III)-hexacyanoferrate(II), obtained by alkaline treatment of the ferro(III)- hexacyanoferrate(II) from wine-making adhesive cyanic waste. The result consists in increasing the efficiency and useful life of the preparation.
