As the flowering season approaches in February/March, the mango tree needs to be replenished with nutrients in order to have enough food for the baby fruit. To supplement the nutrients in the trees, organic and chemical fertilizers should be applied. For this a ditch 60 cm deep, 120 to 150 cm long and 40 to 60 cm wide should be dug around the tree canopy. 20 to 25 kg of organic fertilizer, 0.5 kg urea and potassium chloride should be added in the ditch and regular irrigation done during the spring to promote flower and baby fruit growth.
Tillage is generally done in spring along with the application of fertilizer. In orchards where there are a lot of weeds, weeding can be done by spraying 1% Caogan phosphorus solution (a local weedicide).
The mango tree is attacked by several diseases and insects. One of the most common disease is anthracnos which can be controlled by spraying 0 to 0 Bordeaux mixture or diluted (1000 times with water) 50% Jiajitoubujun (a local pesticide) to the new sprout. Powdery mildew is another common disease in the mango tree, which can be controlled by spraying lime sulfur with a concentration of 0.4 Baume degree. Another common disease is leaf spot, which is, controlled by picking the sick leaves and by spraying 0 Bordeaux mixture or diluted Beijunqing (a local pesticide) with 1500 times water. The insect evening moth is controlled by spraying diluted (80 to 100 times water) mixture of Didiwei, Dibeichong (local pesticides) and 50% ammonium phosphate. The tree should be sprayed 2 to 3 times after an interval of 7 to 10 days. Leaf cicada is controlled by spraying diluted (1500 times) Roger oxide or phosphorus, 1 to 2 times at the beginning stage of insect growth. |
