Abstract:
Field experiment was conducted at Research Farm of PG college Gazipur For the management of spot blotch disease of wheat. One bio-agent, one bioenhancer and seven fungicides were used. Plant disease intensity decreased with the application of different treatment over untreated control. Minimum plant disease intensity was recorded (21.00% first year and 20.70% second year) under T₉ (Seed treatment with Raxil @ 2.5 gm/kg seed + 2 foliar sprays of propiconazole @ 0.1%, first at boot leaf stage second after 20 days), Maximum plant disease intensity was recorded (71.80% first year and 74.00% second year) under T₁₁ (Control), Which has highly significant compared to all the treatments. Maximum grain yield was recorded (39.05 q/ha and 39.25 q/ha first and second year) and maximum thousand seed weight was recorded (42.05g and 42.40g first and second year) under T9 (Seed treatment with Raxil @ 2.5 gm/kg seed + 2 foliar sprays of propiconazole @ 0.1%, first at boot leaf stage second after 20 days), Minimum grain yield was recorded (31.25q/ha and 31.04q/ha during the both year) and least thousand seed weight was recorded(36.30g and 36.18g during 2018-19 and 2019-20) under T₁₁ (Control).
