ECO-FRIENDLY INSECT-PEST MANAGEMENT OF OKRA | Journal of Global Agriculture and Ecology

From mid-April to mid-August 2017, the experiment was done at the field laboratory of Sher-e-Bangla Agricultural University in Dhaka, Bangladesh, to determine the efficacy of various eco-friendly management strategies against numerous okra pests. Four botanical items were used in the treatments. T1 = untreated control, T2 = spraying of Neem oil @ 4 ml/Litre of water mixed with 10ml of trix liquid sprayed at 7 days interval; T3 = spraying of 10ml garlic oil @ 4 ml/Litre of water mixed with 10ml of trix liquid sprayed at 7 days interval; T4 = spraying of 10ml black seed oil @ 4 ml/Litre of water mixed with 10ml of With four replications, the experiment was set up in a Randomized Complete Block Design (RCBD). Fruit and plant infestation was measured by the number, weight, and length of individual fruits during the vegetative and fruiting stages, as well as yield-related characteristics and okra production. Neem oil applied at a rate of 4 ml/Litre of water mixed with 10 ml of trix liquid sprayed at a 7-day interval reduced the highest aphid infestation during both the vegetative (51.10) and fruiting stages (54.06 percent ). The highest plant infestation reduction was 80.45 percent, the highest shoot and fruit borer infestation reduction was 61.10 percent at different fruiting stages, the highest jassid infestation reduction was 47.22 percent and 49.22 percent respectively at both vegetative and fruiting stages, and the highest white fly infestation reduction was 59.64 percent and 59.85 percent respectively at both vegetative and fruiting stages. On the other hand, it enhanced the length (16.03%) and weight (26.80%) of individual healthy fruits, as well as the final output of okra (41.25 percent ). When considering the Benefit Cost Ratio (BCR) and the environment, it is possible to conclude that neem oil is the best alternative.
