Evaluation of bio-efficacy of tebuconazole 430SC against anthracnose (Colletotrichum gloeosporioides (Penz.) Penz. and Sacc) disease of pomegranate

Abstract

Pomegranate (Punica granatum L.) is an ancient and important fruit crop of the world belongs to the family Punicaceae and grown very well under arid regions of the world. Amongst various diseases infecting pomegranate, anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is one of the destructive disease both under field and storage conditions causing severe yield loss. In view of the importance of the disease, a field experiment was conducted on management of anthracnose disease using new fungicides during 2016-17 and 2017-18 at Horticulture Research and Extension Station, Vijayapur (Tidagundi). During 2016-17, Tebuconazole 430SC @ 0.8ml/l recorded least disease severity on leaves and fruits (PDI 7.43 & 2.45) and maximum marketable fruit yield (7.89 tones/ha) followed by Difenconazole 25SC @ 1ml/l (PDI: 8.60 & 4.20, fruit yield: 7.83 tones/ha) and Propineb 70%WP@ 3g/l (PDI: 10.91 & 5.33, fruit yield: 7.02 tones/ha). Similarly during 2017-18 Tebuconazole 430SC @ 0.8ml/l was recorded least disease severity on leaves and fruits (PDI 8.60 & 5.33) and highest marketable fruit yield ( 6.47 tones/ha) followed by Difenconazole 25SC @ 1ml/l (PDI: 9.63 & 6.33, fruit yield: 6.42 tones/ha) and Propineb 70%WP@ 3g/l (PDI: 10.47 & 9.83, fruit yield: 6.31 tones/ha.
