The study used the methods of point selection, household selection, experiment arrangement and monitoring of indicators on experimental formulas that were sprayed with EMINA preparations with different concentrations (1%, 2% and 3%). Research results show that with a concentration of 3% for the highest yield and quality in the experimental formulas
Black spot disease damage leaves and fruit lower than control and the formulation of spraying EMINA preparation with concentrations of 1% and 2%. Specifically, the yield (70.4 kg/tree) was higher than the control treatment (56.67 kg/tree) and the disease on the fruit and leaf showed the least (12.81% and 8.23%). The concentrations of EMINA spray did not affect the growth and development of Sanh orange trees, as shown by the indicators of the time of buds and blooms, but affected the fruit setting rate (higher fruit set rate than the control).
