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: (CH
2
)
n
, 1,3-phenylene and 1,4-phenylene; R
1
is selected from the group consisting of iso-butyl, sec-butyl and tert-butyl-CH
2
; R
2
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.
本文公开了醛和酮的酰肼和半卡巴肼衍生物,可能起到吸引植物病原体游孢子的作用,以及使用这些化合物的方法。这些化合物包括公式1所示的化合物:其中:X选自(CH2)n、1,3-苯基和1,4-苯基组成的群;R1选自异丁基、仲丁基和叔丁基-CH2组成的群;R2是氢或甲基;n等于0-25。在接触水后,这些化合物会释放出醛或酮,可能吸引游孢子。这些化合物可以与杀菌剂结合形成杀菌剂配方,特别有效对抗产生卵菌类真菌病原体。
