Red rot of sugarcane is one of the severe problem for fruitful profitable production of sugarcane. In this why IDM technology are very much helpful to control diseases, pest etc.

IDM MODEL OF RED ROT OF
SUGERCANE

3. Introduction
The importance of sugar in human diet needs no
introduction; it has become a part and parcel of
daily life. Sugarcane is not only cash crop for the
growers, but it is main source of white crystal sugar
and also provide grower with a very good substitute
of sugar in the form of 'gur'.
This crop is subjected to many diseases caused by
fungi, bacteria, nematodes and viruses. But Red
Rot of Sugarcane is one of the fungal diseases. The
disease is the number one problem of sugarcane in
Bangladesh and entire cane breeding in Bangladesh
is geared around this disease. But chemical controls
are not eco-friendly. So, we need to adopt
biological control which is environmentally safe.
Now a day scientists are trying to control Red rot of
sugarcane by mean of IDM (Integrated disease
Management).

4. Objectives
 1. To get information about the
Integrated disease management.
 2. To know about the Red rot of
sugarcane.
 3. To know about the Integrated
disease management of Red rot of
sugarcane.

5. Concept of IDM
According to FAO, “Disease management systems that utilizes all
suitable techniques in a compatible manner to reduce pest
populations and maintains them at levels bellow those causing
economic injury.” (Smith and Reynolds 1966).
So IDM is a durable, environmentally and economically justifiable
system in which damage caused by diseases is prevented through
the use of natural factors which limit the population growth of this
organism, if needed supplemented with appropriate control
measures.
In most cases IDM consists of scouting with timely application of a
combination of strategies and tactics .These may include site
selection and preparation, utilizing resistant cultivars, altering
planting practices, modifying the environment by drainage,
irrigation, pruning, thinning, shading, etc., and applying pesticides,
if necessary.

6. Red rot of sugarcane
Red rot is one of the major constraints in the profitable cultivation
of sugarcane in Bangladesh. This disease drastically retards the
yield and considerably deteriorates the juice quantity and quality
thus hitting both the cane growers and millers.
Causal Organism : Colletotrichum falcatum
Class : Deuteromycetes
Order : Melanconiales
Family : Melanconiaceae

9. conclusion
Red rot is one of the oldest known diseases of sugarcane.
It occurs in most cane-growing countries. Although it
continues to be a threat in certain subtropical countries.
Midrib lesions are probably the major source of inoculum
during the growing season. Diseased stalks generate a
great deal of inoculum. Dissemination of the inoculum
takes place by wind, rain, and irrigation water.
To control these diseases synthetic pesticides are being
used indiscriminately at large scale. Consumption of
pesticides in Bangladesh were 10136.83mt. (BBS, 2003),
of which fungicides were 3445.2 mt. This causes serious
environment pollution and human health. So, for
controlling the environmental pollution as well as to
increase the production of sugarcane we should have to
follow Integrated Disease Management system (IDM)
which will protect our valuable crop & ultimately bring
happiness to our farmer.
