&agr;-Sulfenimino acid derivatives of formula I
including the optical isomers thereof and mixtures of such isomers, wherein
A is cycloalkyl, cycloalkenyl, aryl or heteroaryl, each optionally substituted,
B is a direct bond or optionally substituted alkylene,
E is hydrogen or optionally substituted aryl,
R is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl or arylalkyl, each optionally substituted, and
T is NH or oxygen,
have been found to be useful for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi.
The invention relates the novel compounds and also to the preparation thereof and to the use of the compounds for plant protection, and to compositions suitable for applying the novel compounds in agricultural techniques.
