This kind of disease often occurs in this plant. We can use some pesticides to kill it.
We need to check the branches of the tree often, because there will be a longicorn. If we find it, we need to seal the hole and kill it
This is the key point. It should be allowed to apply dimethoate milk to it at the time of initial incubation. This is 80%, and it needs twice the reagent. In addition, we can apply Omethoate to it. The concentration is 40% and the multiple is 2000. If there are galls or galls in the tree, the concentration should be increased.
If the larva has already hatched at the beginning, or because the leaves are rolled and it has not landed, we can apply phoxim acid to the larva at a concentration of 50% and a multiple of 1000. In addition, the concentration of trichlorfon can be 90% times 1000 to spray.
This needs to be killed at larva time. You can use trichlorfon. LEGO can also work on it. It needs a concentration of 40% and a multiple of 1000. It's also useful to catch its larvae, or to release parasitic wasps
This is to collect its cocoon and bury it in the soil. The methods of collecting cocoons are picking, tapping, digging, etc. In this way, the density of insects will be greatly reduced. And its larva is generally gregarious, we can remove it. In addition, we can use its dependence on light, tempt it, and then get rid of it.
