COMBINATION, CONTAINING 4-PHENYLBUTYRIC ACID (4-PBA) OR A SALT THEREOF (COMPONENT (A)) AND ONE OR MORE SELECTED ADDITIONAL AGRONOMICALLY ACTIVE COMPOUNDS (COMPONENT(S) (B)), THAT REDUCES ABIOTIC PLANT STRESS

摘要

The invention relates to combinations that reduce abiotic plant stress, said combinations containing 4-phenylbutyric acid or a salt thereof (component (A)) and one or more additional agronomically active compounds (component(s) (B)) selected from the range of fungicides, insecticides, safeners, and/or growth regulators or salts of the aforementioned compounds of group (B). In particular, the invention relates to synergistic combinations containing 4-phenylbutyric acid or a salt thereof (component (A)) and one or more additional agronomically active compounds (component(s) (B)) for increasing the stress tolerance in plants toward abiotic stress, preferably drought stress and/or heat stress, and for strengthening the plant growth and/or increasing the plant yield as a result of the increased stress tolerance under said conditions.
