Curative methods
April 29th, 2008 Posted in Management methods
Once the damage is identified based on symptoms, it is important to take up plant protection measures at the earliest. Usually the damaged tissue is removed and a suitable pesticide is applied to the damaged part. The part of damaged stem is drilled with a few holes and an effective chemical in appropriate dose is poured into the holes and sealed. The systemic pesticide will penetrate the stem tissues and kills the pest stages present. Even fumigation is resorted in some cases depending on the type of damage.
If any palm is killed, it is better to cut it into pieces, apply pesticide and finally burn. The material should be properly burnt to prevent escapes. Until the dead palm is disposed of, the adult weevils continue to emerge from inside and spread in the entire garden and cause great damage.

I am giving the methods for management of Red Palm Weevil in coconut gardens. You may soak/drench the crowns of palms with any one of the following chemicals from the local market. Don’t spray as it will splash around and result in wastage of chemical and also pollute more.
1. Chlorpyriphos 40EC (Dursban)
2. Metasystox R 50EC
3. Supracide (Methidathion) 40EC
4. Salut (cypermethrin + dimethoate)50EC or similar one.
For curative action
If you notice a palm showing the symptom on the base of the trunk follow this method.
1. If the damage is superficial and not more than one inch deep, remove the damaged tissue carefully and apply any of the above pesticide or carbaryl (0.1%) and cover with wet clay. Don’t use cement.
2. If absolutely necessary make a hole with drill (mechanical or electric) about 6″ deep in a slanting manner and pour 1% solution of the above or carbaryl.
3. Intercultivation with tractor has to be done carefully. Mechanical damage to stem will attract weevils and more attack in future.

I live in Bali and have only just discovered that one of the bugs that is killing coco nut trees on my property and many of my friends properties is indeed the Red palm weevil.
I love the trees and would like to try injecting them under neath the leaf crown with a suitable chemical.
Can you help me with a name of a product available in Bali Indonesia and some direction as to how much I should inject into each tree.
Thanking you for imformation already learnt from redweevil blog.
Palm lover. Bali.

Dear Dr vidyasagar
A I have some question about Red palm Weevil.I work for a pesticide company for African territories including Maghreb.
Morocco is involvel in biological date palm produce but actually som trees are damaged by Red Palm Weevil. Local producers ask us to find a solution. As pesticide company we can provide to them Chlorpyriphos Methyl 400g/L or Ethyl @ 480 g/L but we don’t know @ wich dosage, timing, number of application and how to apply it.
You speak about aerial spray with some relative efficacy , but @ which rate , how many times ?
For my part I think that injection is the best solution,but I don’t know the dosage you speak about 0.1 % to 1 % solution, does it mean 100 ml formulated product /100 L of water to 1 L formulated product / 100 L of water volume ? How many ml per tree ?
Waiting your comments
Best Regards

Are the nematodes used in some trials as
a biological weapon that can “eat” and poison the weevil inside the palm available ? and where ?
