Which disease affects almond trees specifically, caused by Monilinia?

The correct answer is Brown Rot Blossom Blight, which is caused by the fungus Monilinia. This disease specifically targets almond trees, especially during the blooming period when the flowers are susceptible. The pathogen infects the flowers and can lead to significant crop loss if conditions are favorable for the disease. Symptoms include wilting and browning of the blossoms, which then lead to the formation of brown rot and ultimately fruit drop.

Understanding the impact of Brown Rot Blossom Blight is crucial for almond growers as it emphasizes the need for effective management practices, such as proper timing for fungicide applications and monitoring environmental conditions that favor fungal growth. This knowledge is essential for maintaining the health of almond orchards and ensuring a quality yield.

While Botrytis Bunch Rot also involves fungal pathogens and affects fruit, it is not specifically associated with almond trees or Monilinia. Alternaria Leaf Spot and Shot Hole are diseases that affect various plants but do not specifically relate to the Monilinia genus or the almond tree.
