Mango Fruiting Stage Management Methods and Key Technical Points

When growing mangoes, many people know that the fruiting stage is the most important period. At this time, it is necessary to increase the fruit-setting rate, ensure the amount of fruit set, keep the fruit from dropping prematurely, and meet the nutritional needs of the fruit. Therefore, the fruiting stage is a crucial period that determines yield. The specific management measures for the fruiting stage will be explained one by one below.

I. Fertilizer and Water

Fruit-swelling fertilizer needs to be applied during the fruiting stage; generally, when the fruit is developing, it is also the period when new shoots emerge. Therefore, sufficient nitrogen, phosphorus, and potassium must be supplemented, without favoring any single nutrient, to ensure a balance between vegetative and reproductive growth. In addition, boron fertilizer and calcium fertilizer required by the fruit must be supplemented to avoid fruit drop and tree decline. The fruiting stage requires sufficient water, maintaining soil moisture above 50%. Irrigation is roughly determined by how dry the soil is, but waterlogging must be avoided, and drainage should be done promptly after rain.

II. Foliar Topdressing

During the flowering and fruiting stages, some growth regulators or hormones are used to protect flowers and fruit. These may cause unbalanced or disordered tree growth and lead to physiological fruit drop. Therefore, some good foliar fertilizers can be used to help regulate tree vigor, maintain normal growth, benefit fruit set, and also improve fruit quality.

III. Pay Attention to Pesticide Use

During the period when fruit is present, when disease occurs, be sure to use pesticides that are safe, efficient, environmentally friendly, free of phytotoxicity, and low in residue. Generally, powder-form pesticides should be used less, as powders pollute the environment more, drift easily, and have poor efficacy. Do not spray on windy or rainy days; it is ineffective and requires re-spraying, which increases residue. Common occurrences in mango include angular leaf spot, downy mildew, and anthracnose, which can be controlled with jinggangmycin. Mango peel is thin, so emulsifiable concentrate pesticides should not be used, to avoid damaging the fruit.

IV. Fruit Bagging

To prevent pests and diseases, pesticide damage, and pecking by animals, fruit bagging can generally be carried out after the second physiological fruit drop when fruit set is stable. Before bagging, the tree should be pruned once, and after spraying pesticide once, bagging can be done. Bagging is best completed within one or two sunny days.

The above are some regulatory management measures for the mango fruiting stage. As long as it is fruiting-stage management, it must be taken seriously. Various measures can be used for management, as long as they are beneficial to mango fruit set.
