A Study to Evaluate the Effectiveness of Foliar Application of Salicylic Acid against Mosaic Virus Disease in Capsicum annum

Abstract

India is the world's leading producer, consumer, and exporter of chilli, a commodity with significant worldwide value. Pests, diseases, and viruses pose serious risks to chillies, resulting in large losses every year. A phenolic derivative that is widely distributed in the kingdom of plants, salicylic acid, is known to regulate a number of physiological and biochemical processes, including thermogenesis, plant signaling or defense, and response to biotic and abiotic stress. Salicylic acid's potential as a plant regulator led to the conduct of this study to ascertain its potentized form's effectiveness in varying potencies in preventing Chilli mosaic virus disease in Capsicum annum plants and improving plant parameters. Four groups were used in the study: Group A, B, C and D were administered for placebo, 6C, 12C, 30C respectively. The parameters analyzed in each group are plant height, number of chillies, weight of the chilli, size of the chilli, number of leaves and total yield. The ANOVA single-factor test was used to statistically assess the obtained data. The variations in plant parameters (plant height, number of chilies, weight of the chilli, size of the chilli, number of leaves, and total yield) amongst the four study groups were, respectively, 148.25, 219.58, 67739.8, 14.48, 75.6, and 6.71. At the 5% level, the computed value of F is 11.55, greater than the table value of F crit 2.77 with degrees of freedom v1 = 5 and v2 = 18. Strong evidence to reject the null hypothesis and accept the research hypothesis is provided by the obtained P value of 0.000041, which is less than 0.01. According to the findings of this study, Salicylic acid is effective in enhancing the parameters of capsicum annuum infected with the Chilli mosaic virus at varying potencies.
