Objectives

• To develop bio-based control measure for stem canker and root rot in mulberry
• Leaf extracts ofCalotropis giganteaandTrigonella forenumat 2% concentration inhibited the growth ofLasiodiplodia theobromae. This can be sprayed after every pruning. The cutting can be pre-treated with the extracts before planting.
• Trichoderma viride(BCF-1) &Pseudomonas fluorescensisolated and evaluated can be used to control root rot and stem canker in mulberry.

Important findings

The formulation, ‘Seri-Bioguard’ developed can be used @ 5 kg per hectare in two equal doses enriched with 25-50 kg neem cake to control the disease..
