Abstract

La présente invention concerne un dérivé de 1,3,5-triazine totalement hydrogéné ou complètement hydrogéné, qui présente (i) un groupe selon la formule (a). Dans cette dernière, Q1 représente un groupe de chaîne aromatique qui peut éventuellement être substitué; R1 représente un atome d'hydrogène ou un groupe d'hydrocarbone qui peut être éventuellement substitué; R2 représente un groupe d'hydrocarbure qui peut éventuellement être substitué ou R1 et R2 peuvent former une chaîne ensemble avec l'atome de carbone adjacent. Cette chaîne peut éventuellement être substituée, en position -1, et (ii) des groupes oxo ou thioxo en position -2, et (iii) qui peuvent être substitués à chaque position -3 à -6, à condition que ce dérivé de triazine ne présente pas de groupes oxo au niveau des deux positions -4 et -6, ou un sel de ces derniers. L'invention traite également d'un procédé pour sa production et une composé. Le composé ou le sel de ce dernier présente une forte activité herbicide contre un large spectre de mauvaises herbes, y compris les mauvaises herbes des rizières, et les mauvaises herbes de labour, à de faibles concentrations. En outre, il est moins phytotoxique pour les plantes cultivées telles que le riz, le blé, l'orge, le soja et le maïs et présente ainsi une action herbicide sélective très satisfaisante. En outre, cette action herbicide sélective est une action à longue durée. Par ailleurs, ce composé ou ce sel ne nuit sensiblement pas aux animaux mammifères, aux poissons et aux coquillages. Il n'entraîne également aucune pollution et peut être utilisé en toute sécurité comme herbicide dans des rizières, des labours, des vergers, et des terres non cultivées.
