Abstract/ Executive Summary:

In order to find out the effects of heat therapy and chemo therapy on control of smut an experiment was carried out atBangladesh Sugarcane Research Institute( BSRI ) farm, Ishurdi, Pabna during 2008-2009 cropping season with a sugarcane clone I 149-00. The seed was taken from smut infected clumps. Germination of setts were found to increase in all the treated plots compared to control except HWT at 50 ⁰c for 2 hrs. Possibly due to resistant nature of the variety, the germination was not hampered in the heat treated setts. No disease was appeared in any treated or un treated plots. This was perhaps due to resistance of the host. Number of millable cane was found to increase in all the treated plots compared to control but the difference was not significant except the treatments where setts were treated in Bavistin (0.2%) mixed ( acidulating at pH 3.2) hot water at 52 ⁰c for 30 min. Similar results were also found incase yield. Sett treatment in Bavistin (0.2%) mixed ( acidulating at pH 3.2) hot water at 52 ⁰c for 30 min found best treatment combination in respect of enhancement of germination, number of millable cane production and yield of cane.

Keywords: Sugarcane, Smut, Heat therapy,Chemo therapy

Location: Bangladesh Sugarcane Research Institute( BSRI ) farm, Ishurdi, Pabna

Start Date: 00-00-2008

End Date: 00-00-2009

Program Area: Pest Management

Commodity: Sugarcane

Objectives:

1. To find out the effects of heat therapy and chemo therapy on control of smut.

2. To determine sustainable control measure of smut disease.

Methodology:

An experiment was carried out at Bangladesh Sugarcane Research Institute( BSRI )farm, Ishurdi, Pabna during the cropping season 2008-2009. The experiment was laid in RCB design with three replications. Sugarcane clone I 149-00 was taken from smut infected clumps as planting material. Sett treatment were done in hot water at 50⁰c for 2 hrs, 52⁰c for 30 min, Bavistin (0.2%) mixed ( acidulating at pH 3.2) hot water at 50⁰c for 2 hrs and Bavistin (0.2%) mixed ( acidulating at pH 3.2) hot water at 52 ⁰c for 30 min. Data were taken on germination, disease incidence and different yield contributing parameter.

Achievement/Findings:

No disease was appeared in any treated or un treated plots. This was perhaps due to resistance of the host. Number of millable cane was found to increase in all the treated plots compared to control but the difference was not significant except the treatments where setts were treated in Bavistin (0.2%) mixed ( acidulating at pH 3.2) hot water at 52 ⁰c for 30 min.
