Name a physiological disorder that can occur in cotton.

Blossom drop is a physiological disorder in cotton that can occur due to various stress factors affecting the plant's health. Typically, this phenomenon results from environmental conditions such as extreme temperatures, insufficient water supply, nutrient imbalances, or even pest infestations. When the cotton plants face stress, they may respond by dropping flowers prematurely to allocate resources towards survival and growth instead of reproduction.

In the context of cotton farming, blossom drop is significant because it directly impacts the yield of cotton bolls, ultimately affecting the profitability of the crop. Understanding this disorder is crucial for cotton growers as they seek to manage plant health effectively and optimize production. Proper management of irrigation, fertilization, and pest control can help mitigate the conditions leading to blossom drop, ensuring a more stable and healthy crop yield.
