This remedial measure is used widely all over the world, and mosaic disease has been controlled. Let’s take a farm for example, 50% citrus trees get mosaic disease, however, 83% trees with mosaic diseases turned well by spraying manganese sulfate.
The following aspects should be known when spraying manganese sulfate:
1. Spraying time: The best time to spray manganese sulfate is that when new bud is 10cm tall or before leaves turn green.
