Abstract

The Colletotrichum species that causes anthracnose poses a significant threat to the growth of Capsicum annuum, or ringer pepper, resulting in significant yield losses. Conventional produced control systems can give rise to ecological and economic difficulties, necessitating the need for alternative, workable solutions. This study explores the feasibility and parts of natural inoculants in controlling anthracnose ailment in Capsicum annuum filled in chipped away at hydroponics structures. As organic inoculants, we utilized a wide variety of useful microorganisms, such as Trichoderma harzianum, Bacillus subtilis, and mycorrhizal parasites. At various stages of the Capsicum annuum plant's development, these inoculants were incorporated into the supplement arrangements for tank farming. Anthracnose was observed and compared to untreated controls and synthetically treated plants in terms of its severity. Plants treated with natural inoculants show a significant reduction in sickness rate and severity, as shown by our findings. In fact, Trichoderma harzianum outperformed Bacillus subtilis and mycorrhizal parasites in terms of biocontrol productivity. Through a series of biochemical and sub-atomic tests, the fundamental instruments were examined. Natural inoculants, according to important discoveries, increase the plant's intrinsic safe reaction by causing fundamental obstruction. This is affirmed by the upregulation of pathogenesis-related (PR) characteristics and extended activity of shield impetuses like peroxidase (Unit), polyphenol oxidase (PPO), and phenylalanine antacid lyase (Amigo). In addition, the inoculants improved root development and supplement absorption, enhancing overall establish health and resistance to microorganisms. This study demonstrates that natural inoculants can be a reasonable and effective method for controlling anthracnose in Capsicum annuum grown in improved tank farms. In accordance with the goals of a potential agribusiness, incorporating these biocontrol specialists into aquafarming frameworks can increase crop productivity and reduce the use of compound pesticides.
