The main causes of zucchini flower rot are: gray mold and physiological disorders (temperature drop, high humidity, impeded root development, etc.). In addition, bacteria can also infect the flowers, and in severe cases white bacterial ooze is exuded.
The initial symptoms are: the flowers become water-soaked and wet-rotted, and later gray-black fuzz appears. Some wet-rotted flowers produce ooze (gray-white or yellow-brown) and have a foul odor. In specific control measures, they should be handled differently, but in the current zucchini cultivation and management process, attention should be paid to comprehensively considering the above causes of the disease.
Focus on controlling gray mold, mix in bactericidal agents, and also pay attention to supplementing elements such as boron and calcium. In cultivation management, pay attention to keeping warm, reducing humidity, and enhancing root vitality; in cloudy and snowy weather, pay attention to spraying substances such as Fengshou No. 1, Jieke Feng, Lüfeng 95 and cytokinin on the leaves to enhance plant resistance; appropriately increase the application of phosphorus and potassium fertilizers.
