Covering the whole orange tree  24/24 hours in the last 90 days of the oranges in the tree was noted by the neighbors. It is an excellent way. There is not a significant damaged orange, fall off because of the "red eye butterflies" and the fruit fly.

This is a fruitful covering initiative, initiated by the Nghe An Farmer, who self-applied in commercial orange orchards, which should be reviewed to recommend widely.
