Detailed Explanation of the Causes of Mango Fruit Rot and Its Prevention and Control Methods
Mango is a fruit that everyone relatively likes, with large market demand and excellent economic benefits, but some fruit growers often encounter fruit rot during cultivation. This phenomenon generally occurs during the fruit growth period and harvest period, with the surface looking good while the inside rots. So what causes mango fruit rot? How should it be prevented and controlled? Let's learn about it together.
1. Causes of occurrence
During sensitive growth periods such as the mango flowering stage and the early young fruit stage, the plant is extremely susceptible to infection by pathogens. The pathogens lurk inside the flowers and fruits, and when the fruit expands and the conditions are suitable at the maturity stage, the pathogens begin to multiply rapidly and cause damage, thereby triggering fruit rot. In addition, when the mango tree has insufficient nutrition and poor disease resistance, or when elements such as calcium, magnesium, potassium, zinc, boron and manganese are deficient, fruit cracking or rotting can also occur. Moreover, the occurrence of this disease is also related to temperature, light, rainfall and soil. During the flowering and fruit-setting period and the fruit maturity period, under conditions such as low temperature, abundant rain and insufficient light, the degree of fruit rot also varies.
2. Preventive measures
Spray pesticides on mango plants during the shoot-flushing, flowering and young fruit stages to effectively kill pathogens and inhibit their reproduction, apply more fertilizer to rejuvenate the tree, strengthen tree vigor and repair wounds. In addition, applying calcium carbonate and microbial agents to the soil, or spraying Liangguoan on the leaves, helps reduce the probability of this disease occurring. At the same time, attention should be paid to the soil pH value, keeping the soil neutral, and when the acidity is too high, lime powder should be spread in time to neutralize it. During the fruit period, attention should be paid to light, and appropriate shading can be provided under strong light to avoid sunburn from intense sunlight, which can induce fruit rot.
3. Treatment methods
If a small amount of fruit rot has already occurred, spraying with Liangguoan 150-200 times + garlic oil 1000-1500 times + Wofengsu 600 times has a good effect. For more serious cases, it is recommended to spray a compound systemic chemical fungicide to kill the pathogens. At the same time, in conjunction with root irrigation for yield, Qingkulike 100—200 times + Diliwang 500 times + Wofengsu 600 times can be used for one root irrigation, which can kill pathogens in the soil and root system, promote root absorption capacity and restore tree vigor.
