Abstract

L'invention concerne un procédé et des agents de lutte contre les maladies provoquées par des champignons et des bactéries. Dans un mode de réalisation, des chélates spécifiques d'un ou de plusieurs ions métalliques fonctionnent pour lutter contre les maladies provoquées par des bactéries, chez les plantes. Dans un autre mode de réalisation, on utilise un chélate d'ion de zinc, en même temps qu'un chélate d'un autre métal pour lutter contre les maladies provoquées par les champignons, chez les plantes. Quelques-uns des métaux préférés que l'on utilise en combinaison avec du zinc comprennent le cuivre et/ou le manganèse. Des agents chélateurs préférés comprennent la glycine, l'acide citrique ou le résorcinol. Les chélates peuvent être à base d'acides organiques, d'alcools organiques ou d'amines, et ils peuvent se composer de produits de substitution de noyau aromatique, ou d'autres agents chélateurs synthétiques combinés à un métal.
