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 Dear Dr vidyasagar

Frequent enquiries are received about the management of this pest by me. Some comments are posted on the blog but some remain unpublished as Q & A. I presume the palm you are referring to is canary palm. Many palms despite infestation on the crown remain live with green leaves, as long as the growing tip (apical meristem) is not completely destroyed. So I hope the apical meristem/bud is still intact or the adjoining portion is live. Sometimes, the activity of the bud may revive and the new leaves may start appearing at a later date. The answers for your questions are given below: 1. You have to watch this palm, until the emergence of new leaves. Otherwise, you may wait till all leaves of the crown weather. Up to that point you may have to treat the crown with pesticides to avoid re-infestation. 2. No. Unfortunately your method of transplanting a new juvenile palm in the crown will not work. So I suggest that you better plant a new palm separately near to the infested old palm. Then you will have a choice after one year. If the old palm revives the juvenile palm can be moved to a new place and transplanted. In case the old palm dies, you can remove it and allow the new palm to grow in its place. It is a practice in commercial plantations, to do under planting in a old palm garden, where young palms are planted in between old palms and after 3-5 yrs, the old ones are removed. Thus they maintain productivity levels higher. 3. You are using good chemicals for the treatment of Red Palm Weevil. Both chemicals Destroyer 480 (Chlorpyrifos 48 EC) and Cythrin 10 EC (Cypermethrin 10 EC) mentioned by you can be used against this pest. You may see the link http://blog.redweevil.com/2008/04/introduction/#comment-13 for additional pesticides to control the weevil pest. For making the pesticide use more economical, you must follow the correct dosage and avoid excess.

We unfortunately see lots of cases of red palm weevil attacks in the area and unfortunately one of my Palm trees got attacked a year ago and lost its crown. I cleaned out the crown (quite disgusting, smelling and with several larvas) and treated with pesticides (Destroyer 480EC and Cythrin 10 EC). I continue to treat this palm tree and the rest of my palm trees with Destroyer 480EC and Cythrin 10 EC every 3 month. The remaining leaves on this palm tree (now without the crown) are still green. It is now one year since the Red Palm Weevil attack and there is unfortunately no sign of new leaves in the crown. I have 3 questions for you: 1. Do you think that this palm tree will survive? 2. I was thinking of trying to plant another young palm tree of about 100 cm high in the crown of the palm tree. Do you think that the young palm tree will be able to grow its roots through the host and develop? If so what would be the directions I should follow? 3. Regarding the continuing treatment of the remaining palm trees in my garden, could you please tell me if the pesticides Destroyer 480EC and Cythrin 10 EC are the best pesticides to control the Red Palm Weevil? These 2 pesticides are very efective but are a bit expencive (about 100 Euros) so I would appreciate if you could tell me about other effective pesticides which are less expensive. Thank you very much. Best regards Erik Dear Dr Vidyasager,

So you have to thoroughly check all your palms for any initial sypmtoms as the infestation is right next door to you. Even if you find very little damage, try to treat it properly. In case your neighbor's canary palm was severly infested and adults were suspected to have already flown out, then you have to give a preventive soaking of crowns of palms with carbaryl or any recommended chemical immediately. Also look out for the presence of Rhinoceros beetle attack in any palm as this may be prelude to RPW attack in future. Watch this website for further information on the control of Rhinoceros beetle soon. The adult weevil can fly and reach out to palms several KM away from the infested site.

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.

It is not surprising that many times, the pheromone traps may not capture any weevils, and this may be due to two reasons. One reason could be that there may not be any weevils in the vicinity or the range of attraction. The second and most common thing is improper use of the live pheromone trap. If there is a recommendation by any local expert on the pheromone trap use, you may follow that. Otherwise, I have given some suggestions and tips under the topic pheromone trapping. As a preventive measure you can apply pesticide to other ornamental palms also. I hope you will be able to save your palms. Your feedback is highly appreciated for the benefit of others.

Once you identify the symptoms, try to locate the freshly damaged tissues if any either at the crown or below crown or base of the palm. Then clean the damaged area of the chewed up fibres or gum or both superficially. Then make holes of ¾ or 1” diameter and 6” deep at 45 degrees angle in the stem and apply the insecticide. The insecticide has to be diluted with water as per the instructions. Seal the hole with wet clay or mud to avoid evaporation. If you suspect the infestation is in the crown region, simply pour the insecticide liquid into the crown. No need to drill holes in the crown. It will penetrate into the tissues and will be absorbed and translocated to other parts of the plant. No need to drill holes everywhere on the stem. Monitor the progress and improvement of the palm through the appearance of new leaf in the next 30-50 days.

In Europe you can obtain the lures of R. ferrugineus from Agrisense-BCS ltd., Uk. Generally they supply the pheromone lures of most species. Ask them to give sachet kind rather than vials. 2. The traps need to be used throughout the year. The number of traps may be reduced once the population comes down in two years or so. Again it depends on the of similar methods by neighbors. 3. Regularly plant protection methods have to be applied. Surveillance for any new infestations, treatment of fresh infestation or reinfestation, preventive methods of soaking palm crowns, removal and burning of badly damaged palms should continue even if pheromone traps are kept in the garden. It is the integration of various methods to get the best results. 1. In Europe you can obtain the lures of R. ferrugineus from Agrisense-BCS ltd., Uk.
