Mango diseases anthracnose and blossom blight has caused intense damage to the mango yield and export so its control is required. Fungicides are being used for their control which effects the environment as well as human health so the introduction of different ecofriendly methods for the control of these diseases is the need of hour. For this purpose the study on the ecofriendly management of mango anthracnose and blossom blight has been carried out. Plant extracts of akk (Calotropisprocera), eucalyptus (Eucalyptus camaldulensis), neem (Azadirachtaindica) and garlic (Allium sativum) were prepared. Three different concentrations including 1.25%, 2.5% and 5% of these plants extracts were applied in vitro on fungal isolates of Choletotrichumgleosporiodes causal agent of mango anthracnose and blossom blight. Results were assessed for the best concentration application on mango trees. 5% concentration of each extract was proved to be most effective for the inhibition of Choletotrichumgleosporiodes and 5% eucalyptus extract displayed maximum percentage growth inhibition of 79%. Consequently 5% concentration of each extract was sprayed on the four replicates of mango trees in field application. Results showed that among all botanical extracts eucalyptus ismore effectivein control of both diseases anthracnose and blossom blight.
