Abstract
AbstractThe search for active inducers against diseases in the formula of therapeutic nutrients has become a necessity for many researchers. The study’s chief purpose was to make agronomic farming simpler by applying newly created therapeutic nutrients. The novelty of this research is the applied of algal extracts in adding to minerals as therapeutic nutrion. Calcium (Maxifos Ca), Ascophyllum nodosum (Greencal), and Arthrospira platensis (A. platensis), were tested for induction pepper plant resistance against Fusarium wilt. The disease index (DI), morphological growth, photosynthetic pigments, free proline, total phenol, hydrogen peroxide (H2O2), malondialdehyde (MDA), and antioxidant enzymes as reactions to the induction of protection in challenged tested plants were measured. Results revealed that the use of entirely different treatments significantly minimized the danger of Fusarium wilt. Treatment of infected plants with Maxifos Ca was the best treatment, as it reduced the DI to 25% and thus reduced symptoms and improved the percentage of plant protection from the disease by 69.6%. Surprisingly, it was widely assumed that Greencal was the greatest treatment for restoring vegetative growth, followed by Maxifos Ca and an algal extract, A. platensis. The application of Greencal, followed by Maxifos Ca, and then A. platensis significantly increased the expression of all metabolic resistance indices (phenols, polyphenol oxidase, and peroxidase). The best treatments for reducing the signs of stress represented in (MDA and H2O2) were Maxifos Ca and then Greencal. According to the findings the use of Maxifos Ca, Greencal, and A. platensis as alternate therapeutic nutrients of eco-destructive chemically synthesized fungicides appears to be a significant methodology for reducing the harmful effects of Fusarium wilt on pepper plants.
