METHOD FOR INCREASING THE YIELD OF CROPS

摘要

According to the invention a method for increasing the yield of crops, especially beans, has been found which is characterized by applying a composition comprising as an effective component at least one tetrazolinone of formula (I): wherein R<1> represents alkyl, alkylthioalkyl, halogen-substituted phenyl, halogen- and alkyl-substituted phenyl, halogen-substituted cyclopropyl, halogen- and alkyl-substituted pyrazolyl or alkyl-substituted isoxazolyl; and R<2> represents a hydrogen atom, alkyl or N,N-disubstituted carbamoyl, wherein two substituents of the N,N-disubstituted carbamoyl are identical or different substituents selected from the group consisting of alkyl, phenyl, cycloalkyl, halogen-substituted phenyl and dihydropyranyl,to the seeds of the plants, the plants and/or their habitat. The invention further relates to the use of the compounds of formula (I) as yield increasing agents.
