Abstract:
Okra (Abelmoschus esculentus), the world’s most important crop, is frequently harmed by a variety of pests and diseases. Present-days chemical pesticides are being used to address major pests and diseases of the okra plant. In spite of the fact that chemical pesticides are frequently useful, repeated use of these substances often leads to insects becoming resistant to them, fewer natural enemies, less effective natural control, and damaged eco-systems. Therefore, the management of okra pests and illnesses through biological methods, such as intercropping with sprays of biorational insecticides has become increasingly popular due to increased environmental awareness about sustainable crop production. Intercropping with the support of biorational sprays will increase overall yield and productivity while also offering major economic benefits. By altering the biological structure and surrounding environment, creates an unfavourable environment for pests. Intercropping okra with other crops also increases the population of natural enemies and decreases the incidence of pest population in the field. It helps reduce pests by boosting the population of predators and parasitoids. Bio-rational insecticides, viz., Neem baan, Spinosad, NSKE 5%, and extracts of several botanical plant parts (Neem leaves, garlic cloves, red chillies, and lemon grass leaves, etc.), are being used simultaneously with intercropping to manage pest populations. However, the goal of this study is to evaluate the performance of intercropping with a biorational pesticide combination as a means of reducing major okra pests, as well as the appropriate management system of intercropping with a suitable biorational spray.
