Causes of Zucchini Flower Rot and Detailed Explanation of Prevention and Control Methods
Zucchini is a common vegetable, and during its cultivation, flower rot often occurs, seriously affecting yield and causing huge economic losses to farmers. So what causes zucchini flower rot? How should it be prevented and controlled? Let's take a look.
1. Causes of Onset
There are multiple causes of zucchini flower rot, among which the most important is disease, and the representative one is gray mold, a disease that mainly harms flowers. In addition, when the temperature drops, the flowering period of zucchini has strict temperature requirements; once the temperature is too low, its flowers will stop growing, and over time they will suffer frost damage. There is also excessively high humidity, which breeds pathogens that infect the flowers, hindering root development and reducing absorption capacity, so the flowers cannot obtain sufficient nutrients for growth and rot.
2. Symptoms of Onset
At first, water-soaked lesions appear on the flowers, and the lesions gradually expand and develop wet rot; in the later stage, gray-black mold fuzz also appears, which is the typical sign of gray mold infection. Some wet-rot flowers also ooze pus, which is generally grayish-white or yellowish-brown and accompanied by a foul odor. Therefore, when preventing and controlling the disease, it is essential to distinguish the symptoms well and treat them accordingly, while also strengthening management to prevent the disease from occurring.
3. Prevention and Control Methods
With gray mold as the main target, mixing bacterial agents in during planting can kill pathogens carried by the seeds and reduce the probability of gray mold occurring. At the same time, adding trace elements such as boron and calcium to the base fertilizer can inhibit the growth of harmful pathogens and reduce disease. During cultivation, also pay attention to changes in temperature and humidity; once low-temperature weather occurs, keep warm in time, and during the rainy season drain water promptly to reduce humidity. In addition, during special weather such as cloudy and snowy days, spraying substances such as chitin fertilizer, Harvest No. 1, and cytokinin can enhance the plant's resistance, and appropriately increasing the application of phosphorus and potassium fertilizers can strengthen the plant's disease resistance.
