Abstract

Stem bleeding disease caused by Thielaviopsis paradoxa is also one of the important disease in coconut in Andhra Pradesh. Bio efficacy of native fungal and bacterial bioagents on stem bleeding pathogen Thielaviopsis paradoxa under in vitro conditions revealed that Trichoderma asperellum[Ambajipeta] was significantly superior with 79.17 % growth inhibition followed by T.reesei [Ambajipeta] with 78.33%,. Field evaluation of bio-control agents against Stem bleeding disease in coconut indicated that cake application of T. harzianum & T. reesei formulation completely brought down the disease index by 100 % within 50 days of cake application. Paste application of bioagents viz ., T. harzianum ,T. reesei and chemical fungicide copper oxychloride application were also substantially reduced the disease.
