<p>Novel compounds of the herein defined formula I <IMAGE> are described in which R represents C1-C4-alkyl. These have useful microbicidal properties. They can be used for controlling plant- damaging microorganisms, in particular phytopathogenic fungi. Thus, for practical needs, the compounds of the formula I have a very favourable crop plant protection action, without this being influenced by undesired side effects. They can be used in practice in the form of pesticides. A process for the preparation of these active substances and their formulation to give microbicidal agents and their use in plant protection are also described.</p> |
