Shoot and Fruit Borer Management in Brinjal
Brinjal, also known as eggplant, is a popular vegetable crop cultivated around the world. However, the crop is prone to attack by several pests, out of which the shoot and fruit borers are the most destructive ones. The shoot and fruit borers of brinjal are moth larvae that feed on the tender parts of the plant, causing extensive damage. If not managed properly, these borers can result in yield losses of up to 50%. Therefore, it is imperative to take adequate measures to control them. In this article, we will discuss some effective management strategies for shoot and fruit borers in brinjal.
Cultural Practices: Cultural practices play a crucial role in preventing the incidence of shoot and fruit borers. They include crop rotation, intercropping, and proper field sanitation. Crop rotation refers to growing different crops in the same field over successive seasons, which helps in reducing the buildup of pests and diseases. Intercropping involves planting two or more crops in the same field, which makes it difficult for pests to locate their host plants. Proper field sanitation involves removing the crop residues and weeds that act as breeding grounds for pests.
Biological Control: Biological control is a method of using natural enemies to control pests. In this case, the natural enemies of the shoot and fruit borers are parasitoids, predators, and pathogens. Parasitoids are insects that lay their eggs inside the larvae of the pests, which then develop and kill them. Predators are insects that feed on the pests, while pathogens are microorganisms that cause diseases in the pests. Some of the common natural enemies of shoot and fruit borers in brinjal include Trichogramma chilonis, Bracon brevicornis, and Beauveria bassiana.
Chemical Control: Chemical control involves the use of insecticides to kill the pests. While it is an effective method, it should be used judiciously to avoid adverse effects on the environment and non-target organisms. The most commonly used insecticides for shoot and fruit borer control in brinjal include chlorpyrifos, cypermethrin, and quinalphos. However, it is important to follow the recommended dosage and safety measures while using these insecticides.
Conclusion: Shoot and fruit borers in brinjal are a major constraint to its production. However, through a combination of cultural, biological, and chemical control strategies, it is possible to reduce the incidence of these pests. It is important for farmers to adopt an integrated approach to pest management, which involves a combination of different strategies tailored to their specific farming conditions.
