Ants are a common pest in sugarcane ratoon crops. While they are not very harmful to the sugarcane crop itself, they can cause a lot of damage to the sugarcane crop by disturbing the root system. Ants are also known to protect certain pests like mealybugs and scale insects that can damage the sugarcane crop.
To control ants in sugarcane ratoon crops, various chemical and non-chemical methods can be used. Here are some of the most effective ways to control ants in sugarcane ratoon crops.
1. Eliminate food sources and habitat: Ants need food and shelter to survive. If you eliminate these sources, you can control their population. Make sure to remove any fallen sugarcane, trash, and other debris from the field that may act as a food source for the ants.
2. Use Ant baits: Ant baits are one of the most effective ways to control ants in sugarcane ratoon crops. Ant baits contain toxic substances that are attractive to the ants. The ants feed on the bait, and carry the toxic substance back to the nest, killing the queen and other members of the colony. Proper placement and monitoring of ant baits are essential to achieving maximum effectiveness.
3. Insecticides: Insecticide application is suggested when ant populations are very high. The use of insecticides should be left to professionals, as pesticides are harmful and require proper handling. Apply pesticides according to recommended dosage and timelines.
4. Organic methods: Use of diatomaceous earth, neem oil, and garlic oil as a barrier in the crop is also an effective way to deter ants from the sugarcane crop.
Proper choice of management method depends on various factors like, the scale of ant infestation, and environmental considerations. Consult with experts and your local agronomist for expert advice before initiating ant management activities. By taking the right measures, you can control ant populations in sugar cane, and ensure a more stable and productive crop.
