Common insect pests of hibiscus flower and their solutions

1. Uranus

This disease is often found in this plant, and we can use some pesticides to kill it.

2. Longicorn beetles

We need to check the branches of the tree frequently, because there will be longicorn beetles. if we find it, seal the hole and kill it.

3. Aphids

This is the point, the most important thing is to give it dimethoate milk and so on during the initial hatching. This is 80%, and it needs twice as much reagent. In addition, we can apply omethoate to it at a concentration of 40% and a multiple of two thousand. If there is already a gall or it is produced in a tree, the concentration should be increased.

4. Leaf roll moth

If the larva has hatched at the beginning, or if it does not fall to the ground because the leaves are curly, we can give it caprylic acid at a concentration of 50%, multiples of a thousand. In addition, it can be sprayed with trichlorfon with a concentration of 90% times.

5. Inchworm

This needs to be killed when the larvae are killed, and trichlorfon can be used. Dimethoate can also work on it, requiring a concentration of 40%, multiples of a thousand. Capturing its larvae or releasing parasitic wasps is also useful for getting rid of it.

6. Diamondback moth

This is to collect its cocoon and bury it in the soil. The methods of collecting cocoons are picking, tapping, digging and so on. In this way, the density of worms will be greatly reduced. And its larvae are usually gregarious, so we can remove it. In addition, we can take advantage of its dependence on light, tempt it over, and then get rid of it.
