Self-made method for killing pests of rich trees
1, white wine
When we find that the leaves of Nostoc flagelliforme trees are yellow or diseased, we can dilute them with white wine and water at a mixing ratio of 1: 2. When killing insects, you just need to pour it on the surface of the soil where the rich trees are planted. After watering once a year in April, watering once every half month and watering four times in a row can eradicate pests.

After wiping the pests and yellow branches and leaves of the rich tree with alcohol, we should carefully remove the insects on the rich tree, which can well eliminate the pests of the rich tree and reduce the impact of such diseases in the coming year.
