Discover key facts and strategies for protecting bhendi (okra) crops from common pests and diseases. Sharpen your knowledge of sustainable practices and effective interventions for healthy harvests.
Which of the following is the most characteristic symptom of bhendi shoot and fruit borer (Earias vittella) infestation in the field?
Explanation: Drooping and bore holes in tender shoots are typical of shoot and fruit borer attack. Yellow spots and powdery coatings are associated with fungal or viral infections, while whole-plant wilting is usually due to root or vascular problems. Only the first option directly describes borer damage on bhendi.
What is the most eco-friendly method to manage aphid infestations on bhendi during the vegetative stage?
Explanation: Ladybird beetles are natural predators of aphids, making them an eco-friendly biological control. Chemical spraying can harm beneficial insects, soil fumigation is not effective for above-ground aphids, and granular fertilizers do not control aphids.
To reduce the incidence of Bhendi Yellow Vein Mosaic Virus (BYVMV), which preventive action is most effective?
Explanation: Cultivating virus-resistant varieties is the best way to prevent BYVMV. Excess nitrogen and daily overhead irrigation can worsen problems by encouraging growth and spread, while deep ploughing is more useful for some soil problems, not virus control.
At what crop stage should regular monitoring for fruit borers generally begin in bhendi, considering typical pest behavior?
Explanation: Monitoring should start at the flowering stage, when fruit borers are most likely to infest. Seedling and post-harvest stages are less relevant for this pest, while waiting until harvest is too late for effective intervention.
How does proper weed management contribute to reducing pest problems in bhendi cultivation?
Explanation: Weeds often serve as hosts for pests and viral vectors, increasing risk to the crop. While weeds can contribute to organic matter, that is not their main effect in pest management. Promoting germination and providing shade are not related to pest problems.
