Abstract:
The experiments were carried out to incidence of pest and disease of two tree type Mulberry variety V1 and G4. The experimental study was done in Agriculture Research Station, Bhavanisagar, Tamil Nadu. The plants were planted in different spacing such as 5ft x 5ft, 6ft x 6ft and 7ft x 7ft with randomized block design. Continuous monitoring of major pest and disease in random sampling and incidence were recorded. The highest powdery mildew percent disease index (4.12%), Bacterial leaf spot (3.52%), root rot incidence (9.33%) and pest incidence such as leaf webber incidence (53.00%), Pink mealy bug incidence (54.50%) and thrips incidences (34.50%) in 5ft x 5ft spacing. Regarding the disease incidence, lowest powdery mildew percent disease index (2.75%), Bacterial leaf spot (2.17%), root rot incidence (7.55%) and pest incidence such as leaf webber incidence (19.34%), Pink mealy bug incidence (10.00%) and thrips incidences (9.50%) were recorded lowest incidence in the 6ft x 6ft spacing.
