Explore key principles and challenges in protecting tamarind plants from pests, diseases, and environmental threats in horticulture. This quiz addresses management strategies essential for healthy tamarind cultivation.
Which insect is commonly known to bore into tamarind pods, causing premature seed drop and reduced yield?
Explanation: Fruit borers are a major pest for tamarind, boring into pods and causing direct damage. Aphids and mealy bugs suck sap but rarely cause pod borers' characteristic seed loss. Root nematodes mainly affect the roots, not the pods.
If a tamarind tree shows powdery white patches on its leaves, which disease is most likely responsible?
Explanation: Powdery mildew produces characteristic white powdery spots on leaves. Leaf spot shows as dark or brown lesions. Wilt is marked by drooping and yellowing, while dieback refers to the gradual death of plant parts from tips.
Which practice is central to an effective Integrated Pest Management (IPM) plan for tamarind orchards?
Explanation: Regular monitoring helps detect pests early for timely management, reducing the need for excessive chemicals. Daily pesticide spraying can lead to resistance and is not environmentally wise. Monoculture increases vulnerability, and ignoring infestations allows them to worsen.
What is a recommended cultural practice to minimize fungal diseases in tamarind cultivation?
Explanation: Pruning improves air movement, reducing humidity that favors fungal growth. Overwatering and close spacing create moist environments that support disease. Continuous shade can also trap moisture, encouraging pathogens.
When managing pest outbreaks in tamarind, what is the most important step before applying any chemical pesticide?
Explanation: Correctly identifying the pest ensures appropriate chemical selection and avoids unnecessary applications. Spraying at midday can increase evaporation losses, ignoring label instructions risks crop safety, and using maximum dosages can harm beneficial organisms.
