CA 2253839

The present invention is directed to new compositions of matter comprising the reaction products of a carboxylic acid and a urea having formula (I) where R1, R2, R3 and R4 are the same or different and are selected from the group consisting of hydrogen, substituted and unsubstituted alkyl, allyl, vinyl and alkoxyl groups having from 1-6 carbon atoms, substituted and unsubstituted phenyl groups and the halides. Preferably, the reaction product of the present invention is N,N'- diformylurea or N,N'-diacetylurea. These reaction products, e.g., diformylurea, have been found to produce significantly improved growth in a variety of agricultural products when applied to the seed, to the surrounding soil or to the foliage of the emerging plant. Because of the similarity in the carbon, nitrogen, oxygen structure of these reaction products with many biological compounds, it is believed that the reaction products of the present invention may find use in a variety of biological applications.

Nouvelles compositions renfermant des produits de réaction d'un acide carboxylique et d'une urée de la formule (I). Dans cette formule R1, R2, R3 et R4 sont identiques ou différents et sont choisis dans le groupe constitué par hydrogène, des groupes alkyle, allyle, vinyle et alkoxyle substitués ou non contenant de 1 à 6 atomes de carbones, des groupes phényle substitués ou non et des halogénures. De préférence, le produit de réaction de l'invention est une N, N'-diformylurée ou bien une N-N'-diacétyle urée. Il a été constaté que ces produits de réaction, comme la diformylurée, améliorent considérablement la croissance de toute une série de produits agricoles lorsqu'ils sont appliqués à la semence, au sol environnant ou sur le feuillage de la plante naissante. Du fait de la similarité de la structure carbone, azote, oxygène de ces produits de réaction avec de nombreux composés biologiques, on estime que ces produits de réaction peuvent trouver leur utilité dans diverses applications biologiques.
