A method for producing agricuturally active substances such as pesticides to provide improved resistance to environmental degradation, especially heat and ultra-violet light. The method involves the direct reaction of an active protein toxin of a biologically derived pesticide with a UV protectant to form a stable complex having the UV protectant as an integral part of its structure. The method employs lignosulfonates, such as sulfite lignin or sulfonated lignin, or alternately sulfonated lignite, sulfonated tannins, naphthalene sulfonates or other related compounds as the UV protectant.
Un procédé sert à produire des substances actives en agriculture telles que des pesticides afin d'améliorer la résistance aux atteintes de l'environnement, surtout la chaleur et la lumière ultraviolette. Selon ce procédé, on fait réagir directement une toxine protéinique active d'un pesticide d'origine biologique avec une substance faisant écran aux U.V., de manière à obtenir un complexe stable qui contient la substance faisant écran aux U.V. comme partie intégrante de sa structure. Ce procédé utilise des lignosulfonates, tels que la lignine de sulfite ou la lignine sulfonée, ou, dans une variante, de la lignite sulfonée, des tanins sulfonés, des sulfonates de naphtalène ou d'autres composés apparentés comme substances faisant écran aux U.V.
