PYRIMIDINE DERIVATIVES COMPOSITIONS CONTAINING THEM, AND THEIR USE AS FUNGICIDES

摘要

Pyrimidine derivatives of the formula I <IMAGE> (I) in which the variables are herein below described in the specification. R3, R4 and R5 optionally together with the radical R3 are a component of a maximally unsaturated lambda -membered ring where lambda is 3 to 8, two radicals R6 to R9 together may form a component of an unsaturated or saturated m-membered ring where m is 5 or 6, k is 0, 1 or 2, n is 1 or 2 and the addition salts thereof, their preparation, compositions containing them, and their use in the control of harmful fungi.
