Abstract:
Banana is one of the important commercial fruit crops grown in the tropical and sub-tropical regions not only in India but also in the world. Production and productivity per unit area in India is very low. Low production and productivity may be due to many factors, among them diseases are playing a major role. Many micro-organisms caused diseases like viruses, bacteria, fungi and nematodes. The most important and economically destructive disease is "Panama wilt", it is also called as Fusarium wilt incited by Fusarium oxysporum f. sp. cubense. The Panama wilt disease is most destructive due to the emergence of new pathogenic race i.e. Tropical race (TR4). In the present time, this disease caused severe damage and farmer face huge problems due to this disease. For management of this disease, six different SAR molecules were evaluated against Fusarium oxysporum f. sp. cubense TR4 under pot condition. Among the six different SAR inducing molecules maximum 90 days were taken in the first appearance of the wilt symptom in BABA at 0.04 g/l concentration followed by salicylic acid 78 days at 1.0 g/l, Isonicotinic Acid 74 days and Acibenzolar-S-methyl 72 days at 0.20 g/l while in Benzoic Acid 72 days at 1.0 g/l and minimum in Probenazole 68 days after transplanting at 0.20 g/l concentration. BABA (0.04 g/l) was found highly effective in which only 14% wilt index was found followed by Isonicotinic Acid (0.20 g/l) with 28% wilt index, Salicylic acid (1.0 g/l) with 32% wilt index, Acibenzolar-S-methyl (0.20 g/l) with 35% wilt index, Benzoic Acid (1.0 g/l) with 34% wilt index while in Probenazole (0.20 g/l) 38% wilt index was recorded. In control 95% wilt index was recorded.
