Compositions comprising resinous exudate metabolites from plants of the genus Adesmia, used to control and treat infections in plant crops; and methods for controlling infections in plant crops.

Abstract

The present invention relates to compositions and methods for controlling infections in plant crops, comprising the application of metabolites to crops infected with various microorganisms, such as microorganisms of the genus Pseudomonas, Erwinia, Bacillus, Botrytis and Phytophthora. The invention also relates to the use of a compound selected from: 2′,4′-dihydroxy-3-(methyl-2-buten-1-yl) dihydrochalcone (1); glabranine (2), isochordine (3), 2′,4′-dihydroxychalcone (4), 7-Hydroxyflavanone (5), chordine (6), izalpinine (7), 2′,4′-dihydroxydihydrochalcone (8), 2′,4′-dimethoxydihydrochalcone (9) and 2′,4′,6′-trihydroxy chalcone (10), in order to prepare an agrochemical composition to control infections in plant crops.
