Abstract/Description: | The fungal diseases like red rot, smut and smut were responsible for the elimination of many elite commercial varieties in the past in different epidemics. Additionally many of the non-fungal diseases contribute to decline in their performance due to ‘varietal degeneration’. Lack of awareness on seed cane health and ignoring quarantine regulations resulted in introduction of diseases, their epidemics and varietal degeneration in the country. Sugarcane varieties vary in their potential against different diseases and any elite commercial variety may not possess tolerance against all the major diseases. Hence to sustain the productivity in such varieties alternate management strategies need to be developed. Recent outbreak of pokkah boeng and rust in different parts of the country could be due to climate change. Hence factory personnel need to be aware of emerging diseases and develop preparedness to tackle emergencies arising out of disease epidemics. Establishing disease-free nursery chains of sugarcane varieties across the country would facilitate healthy sugarcane in the field and varietal vigour will also be maintained in the long run. In this regard, multiplication of disease-free seedlings through tissue culture needs special emphasis. We offer virus-indexing service to tissue culture production units in the country. This combined effort would lay foundation to create seed nursery chains in different regions to produce quality planting materials. Ultimately these efforts would increase sugarcane productivity and sustain sugarcane cultivation in the country. Early shoot borer, internode borer and occasionally top borer cause significant damage to the crop in the tropical cane ecosystem. Sporadic incidences of scale insects, whiteflies, pyrilla, mealybugs and aphids have been reported here and there in the tropical cane belt. Although the upsurge of sucking pests occurs occasionally in the cane ecosystem, outbreak of invasive pests like woolly aphid disturbed the cane ecosystem to a greater extent in the past decade. Apart from being pests of sugarcane, some sucking pests like aphids are proven vectors of emerging viral diseases of sugarcane. Termites and white grubs are the important subterranean pests. Although the cultivation of insect resistant varieties with outstanding yield potential appears to be the attractive option for managing the pests of sugarcane, lack of availability of resistant varieties drives the cane farmers to go for insecticides during the early stages of crop growth and biocontrol agents during the later stages when the insecticidal application becomes impractical due to dense crop canopy. |
