Control of Sugarcane Mosaic Disease of Flowering Germ Plasm by Serial Hot Water Treatment

Md. Mostofa Kamal
Principal Cane Pathologist
Pathology Division, Bangladesh Sugarcane Research Institute, Ishurdi, Pabna

Abstract/ Executive Summary:

Sugarcane mosaic is a seed piece transmissible disease. Some flowering germ plasm of sugarcane are cent percent infected by mosaic. To use these flowering germ plasm as parent material for breeding program it is necessary to use mosaic free plant. For this reason to identify the efficacy of serial hot water treatment on the control of SCMV strains an experiments was under taken at Bangladesh Sugarcane Research Institute( BSRI ) farm, Ishurdi. Results revealed from the experiments that no clump was found free from mosaic. That is , the treatment combinations are ineffective in controlling sugarcane mosaic disease.

Keywords: Sugarcane, Mosaic disease, Hot water

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

Start Date: 00-00-2003

End Date: 00-00-2004

Program Area: Pest Management

Commodity: Sugarcane

Objectives:

1. To study the efficacy of serial hot water treatment on the control of SCMV strains.

2. To produce disease free breeder seeds for multiplication.

Methodology:

An experiment was undertaken on 22^nd October during the cropping season 2003-2004 to produce mosaic free plant by serial hot water treatment of seed materials. Six sugarcane germ plasms viz. Co 604, Co 775, BO 22, I 205-97, CoL 66 and CP 44-101 were employed for this trial. Three treatment combinations were undertaken. They were: T₁-Sett treatment by hot water at 55°C/ 7 min on 1^st day, 57.3°C/10 min on 2^nd day, 57.3°C/10 min on 3^rd day and 57.3°C/15 min on 4^th day; Ta-Seed treatment by hot water at 55°C/ 7 min on 1^st day, 57.3°C/15 min on 2^nd day, 57.3°C/15 min on 3^rd day and 57.3°C/15 min on 4^th day and Js- Seed treatment by hot water at 55°C/ 7 min on 1^st day, 57.3°C/20 min on 2^nd day, 57.3°C/20 min on 3^rd day and 57.3^:C/20 min on 4^th day. Check plots were also maintained. Two hundred and fifty two budded setts of each variety were taken against each treatment.
