Isolation and in vitro evaluation of bio control agents against anthracnose of sorghum caused by Colletotrichum graminicola

Abstract

Sorghum is subjected to several diseases at all the stages of its development. Sorghum belongs to the family poaceae. It is one of the most important cereal crops in India, it stands fifth most important world cereal crop after wheat, rice, maize and barley. Among all the diseases infecting sorghum, anthracnose caused by Colletotrichum graminicola is one of the most destructive foliar diseases in sorghum. According to present investigation under in vitro conditions, Three antagonistic fungi of Trichoderma species were tested against Colletotrichum graminicola under in vitro conditions by using the dual culture method the results revealed that Trichoderma harzianum has most promising antagonist against Colletotrichum graminicola.
