<p>A plant-cleansing agent comprised of i) at least two amino acids and/or natural carboxylic acids or their derivatives or salts, ii) purine and/or pyrimidine or their derivatives, iii) vitamin or their derivatives or precursors, that include about 0.1 to 10 parts by weight of a separate compound of group I, about 0.001 to 1 part by weight of a separate compound of group II and about 0.001 to 1 part by weight of a separate compound of Group III. This agent can be used for various purposes, such as to prevent and treat plant diseases caused by biotic factors as well as to increase and ensure the yield of the crop plants. It is very efficient particularly when it is combined with extracts from fermentation products, like compost, and enhances their unique action. Within the framework of the above mentioned uses, the desired results are also achieved when just one amino acid is included in the described preparation.</p> |
