Rhyncolure: Effectively attracts the American Palm Weevil which is the main vector for the Red Ring Disease in Coconut Trees
Three major symptoms of the Red Ring Disease are –
- The yellowing and drying that starts on the oldest leaves and then progresses to the youngest leaves
- The youngest leaves produced are small in size and often deformed
- Internally the plants show discolored areas on the trunk, which in the case of the coconut form a reddish ring
Rhyncolure contain the pheromone rhynchophorol, which allows the regulated release of the substance into the environment. This bait attracts adult weevils of both sexes, and once it has been place in the field, its effect last for approximately three months
1 Acre requires 1 Rhynco-Lure Trap
SUBSTRATE FOR AMERICAN PALM WEEVIL PHEROMONE TRAP (RNYNOCLURE)
- Cut sugarcane into 5 to 6 inch pieces and then length ways into 4 pieces.
- To one litre of water add 2 teaspoons of sevin 85% (carbaryl) and 75 ml of molasses and stir properly to dissolve the sevin and molasses into solution.
- Add the cut sugarcane pieces to the solution and let soak for about an hour.
- Next place about 5 to 6 soaked pieces of the sugarcane into the bottom of trap and add the pesticide solution above to just cover the sugarcane pieces.
- Replace the sugarcane and pesticide solution every 2 weeks to ensure continued kill of the weevils.
