Termite attack is a serious problem in sugarcane cultivation and can cause heavy yield loss if not controlled in time. Termites mainly damage the crop by feeding on setts (seed cane), roots, and underground portions of the plant. Affected plants show poor germination, yellowing, drying, and in severe cases, complete plant death. Termite problems are more common in dry soils, sandy soils, and fields with low organic matter. With proper and timely management, termites in sugarcane can be controlled effectively.
The first step in controlling termites is good field preparation. Deep ploughing before planting helps destroy termite colonies present in the soil and exposes them to sunlight and natural enemies. Fields with a history of termite infestation should be prepared carefully and kept clean. Removing old crop residues, stubbles, and woody materials is important, as these provide food and shelter for termites.
Soil moisture management plays a key role in termite control. Termites are more active in dry soil conditions. Maintaining adequate soil moisture through timely irrigation reduces termite activity. However, waterlogging should be avoided, as it can cause other problems like root diseases. Light and regular irrigation helps keep termites away and supports healthy crop growth.
Using healthy and treated seed cane is very important. Sugarcane setts should be free from damage and disease. Before planting, treating setts with recommended insecticides helps protect them from termite attack during the early stages. Sett treatment is one of the most effective methods because termites often attack the crop soon after planting.
Organic matter management also helps in reducing termite damage. Applying well-decomposed farmyard manure or compost improves soil health and encourages beneficial organisms that naturally suppress termites. Fresh or undecomposed organic material should be avoided, as it may attract termites. Adding organic matter also helps retain soil moisture, making the field less favourable for termites.
Crop rotation is another useful practice. Continuous sugarcane cultivation increases termite population in the field. Rotating sugarcane with crops like rice or other irrigated crops helps reduce termite infestation, as termites do not survive well in wet conditions. Including green manure crops before sugarcane planting also improves soil condition and reduces pest pressure.
Regular field monitoring is essential for early detection. Farmers should check for poor germination patches, dried shoots, and hollowed setts. Early identification allows timely control and prevents spread to healthy areas of the field.
When termite infestation is severe, chemical control becomes necessary. Soil application of recommended insecticides at the time of planting or during early crop growth helps control termites effectively. In infested fields, insecticides can also be applied through irrigation water or as soil drenching near the root zone. Chemicals should be used carefully and only at recommended doses to avoid harm to the crop and environment.
Maintaining balanced nutrition also helps plants tolerate termite damage better. Healthy and vigorously growing sugarcane plants are less affected by pests. Adequate potassium strengthens plant tissues and improves overall plant resistance.
In conclusion, controlling termites in sugarcane requires a combination of preventive and corrective measures. Proper land preparation, sett treatment, timely irrigation, use of organic manure, crop rotation, and regular field monitoring are the most effective practices. Chemical control should be used only when necessary. By following these simple and practical steps, farmers can protect their sugarcane crop from termite damage and achieve better growth and higher yields.
