Abstract
Two field experiments were conducted field experiment were designed in a split plot design with three replicates in Al- sadat city location during the 2019/2020 and 2020/2021 growing seasons where the faba beans cultivars 429 were placed in the main plots and the three treatments and the control were placed in the sub-plots. Efficay oof chemical inducers, i.e. Ascorbic cid, salicylic acids and Houmic acids as foliar spray against of chocolate spot disease severity of faba bean (Vicia fabaL.) cv. Giza 429 was evaluated. All treatments recorded the highest efficacy percentage for reducing severity of chocolate spot disease which caused by Botrytis fabae and/or B. cinerea compared to control during the 2019/2020 and 2020/2021 growing seasons. Also, all treatments increased faba bean yield, pods number/plant, seeds number/pod, 100-seed weight, seed yield/ plot, seed yield/ fed., peroxidase and polyphenol oxidase activity as compared to non-treated plants.
Ascorbic acid is the most superior positive resistance effect, increasing the yield and enzyme activity content of faba bean among other inducers. In the contry, Houmic acids expressed the lowest effective one during the two successive seasons 2019/2020 and 2020/2021 in comparison with control treatment.
