METHOD OF PROTECTING GRAPEVINES AGAINST GRAPEVINE YELLOW DISEASE

摘要

The present invention relates to a method of protecting grapevine plants against grapevine yellow disease caused by the phytoplasms Bois noire and/or Flavescens doree, which comprises treating the shoots or the soil in root proximity with an effective amount of a compound (I) in which R1 is hydrogen or C1-C4-alkyl and R2 is C1-C4-alkyl or C3-C6-cycloalkyl, or agriculturally acceptable salts thereof. In addition, the invention relates to the use of combinations of a compound (I) for inducing tolerance of grapevine plants to Bois noire and/or Flavescens dorée.
