Abstract
Abstract A new series of 2-pyrazinemethanols useful for the protection of plants from microbial diseases has been discovered. The new compounds are characterized by alkyl, cycloalkyl or phenyl substituents on the Alpha -carbon and by a single additional substituent on the pyrazine ring. Many of the compounds are additionally useful for the inhibition of plant growth.
