Chilo infuscatellus Snellen is a major pest of sugarcane, particularly in the early stages of the shoot. The larvae bore into the young shoots and feed on the nutritious tissue, causing severe damage to the plant and reduced yields. Hence, controlling this pest is essential for the productivity and profitability of sugarcane farming.
To control Chilo infuscatellus Snellen, farmers must adopt integrated pest management techniques. This approach combines various control methods to reduce the population of the pest to an acceptable level. One of the most effective methods of control is the use of insecticides.
Insecticides such as chlorpyrifos, carbofuran, and quinalphos have been found to be effective in controlling the early shoot borer infestation in sugarcane. The application of insecticides should be timed properly to target the early-stage larvae before they bore into the shoot. Farmers should spray the insecticides when the crop attains a height of about 20-30 cm. This should be done during the evening hours to avoid the loss of efficacy due to light exposure.
Another effective control method to manage Chilo infuscatellus Snellen is the use of resistant varieties. Resistant varieties have been developed through breeding programs and are available for farmers to grow. These varieties have been found to have improved resistance to early shoot borer infestation. Hence, farmers should choose resistant varieties for cultivation to reduce the incidence of Chilo infuscatellus Snellen.
Cultural practices can also be employed to manage Chilo infuscatellus Snellen. For instance, farmers should practice clean cultivation by removing weeds, which act as hosts for the pest. Additionally, the use of pheromone traps can be an effective way to monitor the pest population and alert farmers to take necessary measures.
In conclusion, Chilo infuscatellus Snellen is a major pest of sugarcane, which can cause significant losses to farmers. Effective management of this pest requires the adoption of integrated pest management techniques, including the use of resistant varieties, insecticides, and cultural practices. By implementing these measures, farmers can improve the productivity and profitability of their sugarcane farming.
