Field management of Taro (Colocasia esculenta (L.) Schott) leaf blight via fungicidal spray of foliage
نویسندگان
چکیده
Taro leaf blight (TLB) epidemic hit Cameroon for the first time in 2009. Since then, disease is persistent and its typical devastating legacy threatening (Colocasia esculenta) North South West Regions of Cameroon. This study was initiated with objective to determine potentials some fungicides control TLB. The experimental design completely randomized a 3x15x2 factorial, including 3 treatments: T1 (Callomil plus72WP), T2 (Mancoxyl plus 720WP) T3, 1:1 ratio + all applied at concentrations 4g/L; 15 repetitions 2 planting seasons (dry season i.e. October 2014 – March 2015 rainy April-October 2015). Disease incidence severity were used evaluate progression while corm yield appraise economic injury. results revealed 0% during dry 18.2%, 27.3% 100%, T1, T3 respectively. 75% only 1% different treatments. Corm 17.4kg, 15.08kg, 14.27kg 5.89kg T2, suggests that TLB can effectively be managed by foliage spray Metalaxyl containing weekly dosage 4g/L.
