  • Publication number: 20100254936
    Abstract: Disclosed herein are acylhydrazone and semicarbazones derivatives of aldehydes and ketones that may act to attract plant pathogenic zoospores and methods of using these compounds. These compounds include the compound according to Formula 1: wherein: X is selected from the group consisting of: (CH2)n, 1,3-phenylene and 1,4-phenylene; R1 is selected from the group consisting of iso-butyl, sec-butyl and tert-butyl-CH2; R2 is hydrogen or methyl; and n is equal to 0-25. Upon exposure to water, these compounds release aldehydes or ketones that may attract zoospores. These compounds can be combined with fungicides to form fungicidal formulations that are especially effective against oomycete producing fungal pathogens.
