Sugarcane is commonly affected by a variety of insect pests, especially during the seedling stage. These include termites, beetles, sawworms, borers, cotton aphids, thrips, aphids, and armyworms, as well as pests that attack the roots, such as sugarcane root borers. To ensure healthy growth, regular monitoring and timely pest control measures are essential.
For underground pests, one effective method is to soak the planting trenches with pesticide solutions mixed with fine soil before planting. This helps to create a protective barrier against soil-dwelling insects. For foliar pests, spraying with trichlorfon or dimethoate can be highly effective. Always follow the instructions provided on the pesticide labels for safe and proper application.
In terms of diseases, the main issues at the seedling stage are shoot rot, smut, brown stripe, and brown spot. To manage these, it's important to start with disease-resistant varieties and properly disinfected seedlings. Good early management practices, such as adequate fertilization and drainage to avoid waterlogging, also play a key role in disease prevention. If symptoms appear early, affected cane should be manually removed and taken out of the field to prevent further spread.
With consistent and careful management, major pest and disease outbreaks can be effectively controlled. Regular inspection, proper cultural practices, and timely intervention are all crucial to maintaining a healthy sugarcane crop.
