Rosette flowers in cotton are caused by:

✅Explanation:Pink boll worm (Pectinophora gossypiella) is the primary culprit behind the formation of rosette flowers in cotton.
-Symptoms: The damaged flower buds remain closed and the bracts (protective leaf-like structures) spread outwards, creating a rosette-like appearance. This is distinct from a healthy cotton flower, which opens and exhibits a bell-shaped corolla.

📌 Other options Explanation:
-Spotted bollworm (Earias vitella): This pest primarily targets squares (developing bolls) and young bolls, causing damage but not typically leading to rosette flowers.
-Red boll worm (Diparopsis rosea): While it can damage flowers and bolls, its feeding behavior does not specifically cause rosetting.
-Spiny bollworm (Earias insulana): Similar to the spotted bollworm, this pest focuses on squares and bolls, not causing rosette flowers.
