✅ Insects, pests of durian by leaf stage.

Insect pests of durian by leaf stage and insect eradication agent.

Effective management of durian insects must start by understanding that each insect will destroy at different "strokes" according to the development of the leaf, so that you can use the most effective and cost-effective anti-removal agent.

Durian enemy insects are divided by leaf stage and management guidelines.

1. Soft leaf break: This is the most critical phase because young leaves are a good source of food and are highly vulnerable.

* Bantam aphid: larvae suck the young leaf juice, causing the leaves to kink, dry and fall.

- Recommended Eliminator: Fipronil, Imidaclopryd, Dinotifuran

* Aphids: Use a stabbing mouth to suck vitreous water from young leaves, young shoots, and midleaf lines, causing kink leaves to bend, warp, deform, very epidemic in arid weather.

- Recommended anti-removal agent: Spineitoram, abamectin, chlorphenapper

* Fringed cicada aphid: suck the vitreous under the leaves, causing the edges of the leaves to burn and fall (incense groans)

- Recommended Eliminator: Lambda-Cyhalothrin, Buprofesin

* Leaf-eating worms / leaf-rolling worms: Bite, eat young leaves until cleft or left with leaf lines.

- Recommended protective agent: emamectin benzoate

2. Peslad leaf stage: When the leaves begin to spread fully but are not very old, insects that like to suck the vitreous will remain, and there will begin to be a group of "mites."

* Red mite (especially dry season): will suck up the face of the leaf until it is pale white as if it were dust on the island. The leaves will fall and fall.

- Introducing agent: pyridaben, spiromesifen, Amythraz

* Aphid: Often perched behind leaves or branches, borne by ants.

- Introduction: Tai-amytoxam mixed with White Oil to help infiltrate

3. Old leaf stage: The leaves will be tougher and stiffer. Bite mouth insects will be less, but be careful of the accumulated group to wait for the outbreak in the next leaf cycle.

* Shellfish aphid: The island sucks up the vitreous water along the midline of leaves and branches, causing the tree to deteriorate.

- Recommended substance: pyriproxifen, or the use of white oil / petroleum oil, sprayed to control eggs and embryos.

* African red mites: still need to be monitored if the weather is dry and hot.

- Introducing agent: pyridaben, spiromesifen, Amythraz

* * Additional instructions to spray.

- Switching groups of action mechanism: To prevent drug-resistant insects, the same group of substances should not be used more than 2-3 times in a row.

- Soft Leaf Management: Should start spraying protective agents from the start of cresting, because if the leaves are spread and the damage marks are usually handled indefinitely

- Use of leaf binders: Using good quality leaf binders will help the drug stick and stay active longer.
