This document summarizes information about red rot disease of sugarcane. It begins with an introduction about the importance of sugarcane as a source of sugar production. It then discusses the history of the disease, first reported in Java in 1893. The causal organism is Colletotrichum falcatum, which has both asexual and sexual reproduction stages. Symptoms appear after rains when plant growth stops and sugar formation begins, showing yellowing, shriveled canes with reddening pith. The disease cycle and management approaches are also summarized, including using disease-free setts, hot water treatment, removal of infected stools, crop rotation, and resistant varieties.

4. INTRODUCTION
IMPORTANCE OF SUGARCANE
 The importance of sugar in human diet needs no introduction; it
has become a part and parcel of daily life. Sugar is produced
mainly from sugarcane and sugarbeet and more than 75 percent
of the world sugar comes from sugarcane.
Sugarcane is a native of India and has been in use for
‘gur’making since prehistoric times. ‘Gur’ was known as early as
3000 BC
Use as a Gasohol

5. HISTORY OF DISEASE
Red rot of sugarcane was first reported in 1893 from java
(indonesia)
The accepted name,‘Red rot’ was given to this cane
disease in 1906 by Sir E. J. Butler, the celebrated Imperial
Mycologist of India,who was then working at Pusa,Bihar.
The disease was first seen in India in 1901 near Godavari
Delata of Andhra Pradesh, India.
Epidemic in 1939 – 40 in east UP & Bihar
In 1950 It has always damage a lot of sucrose content
variety,coj 312, of sugarcane.

6. Symptoms of Disease
 Appear after rainy season when pl. growth
 stop & sugar formation start
 Third leaf from top start - yellowing
 Later infected cane – shriveled
 Rind shrink
 Cane light in weight & easily broken
 Reddening of pith with clear area (white) running
 across the width of the cane

9. ETIOLOGY
 Causal Organism :- Colletrotrichum falcatum
 Perfect stage:- Glomerella tucumanensis
The fungi causing the disease occur in two stages.
 These are the asexual stage, which is called anamorph
or imperfect stage .
 Perfect stage :-which is called teleomorph or the
Sexual stage. Perfect stage of fungus means When it
reproduces sexually.
Soil born disease

12. Disease Management
 Use Always Disease free setts
 Setts treatment – Carbendazim @ 2.5 gm/lit. of water for 30 minutes
 Hot water treatment – 52° C for 8 hrs
 54° C for 2 hrs
 Hot air treatment - 54° C for 6 hrs
 Removal of infected stools
 Crop rotation 2-3 yrs
 Use disease Res. Varaties.- Cos -767, Co- 840, Co- 1148, Co- 1158, Bo-32
 Co. 975, 1148, 1158, 1336 and 6611; Co. S 561, 574; B.O. 3, 10, 47.
