Abstract:

The potential use of urea in eliminating Fusarium oxysporum f. sp. cubense (Foc TR4) from infected Cavendish banana plants was investigated. In vitro tests, found that urea at 1% and 2% (w/v) eliminated the fungus in Fusarium wilt infected banana tissue, when measured 7, 14 and 30 days after treatment. Furthermore, urea at 0.5% and 0.25% (w/v) reduced the growth of the fungal colony of Foc TR4 by 38.5% and 31.2% on Nash Snyder medium. Prolonged treatment at 14 and 30 days further reduced fungal recovery on treated banana tissue from 5.5% to 12.2%. Greenhouse tests revealed that there was no infection in banana tissue grown in soil inoculated with TR4 and treated with 1% and 2% (w/v) urea two months after incorporation into the soil. This study provides evidence of the efficacy of urea as an alternative to rice-hull burning to eliminate Foc TR4 from infected banana tissue both in vitro and in vivo for the Philippines.
