It is forecasted that in the coming time, when oranges enter the ripening period, infected gardens and fruit drop will continue to increase, especially after heavy and prolonged rains.
To prevent and limit damage caused by orange fruit drop,Department of Agriculture and Rural DevelopmentRequest the People's Committees of districts, local professional units and farmers to urgently implement a number of measures: Implement good drainage for orange gardens, avoid flooding or local flooding of orange gardens. Do not fertilize immediately after rain.
For orchards with fruit loss due to fungus, it is necessary to use drugs such as Aliette 80 WG, Insuran 50 WG, Ridomil gold 68 WG... to water around the canopy and spray on the trees. Trees with fruit loss due to Greening disease need to be supplemented with nutrients through the leaves to harvest, then cut down and destroy to limit the spread of the disease.
In orchards where fruit falls due to nutritional imbalance, farmers must strictly follow technical procedures for care, fertilization and pest control as recommended by professional agencies./.
