Coconut garden area is recovering well with a campaign launched to prevent black headed coconut worm.
The total area of coconut trees in the province currently infected with landslides is 271.45 hectares, of which 609.61 hectares have been completely restored. The results show that, up to now, 100% of the inspected landslide-infected areas have shown signs of good recovery, of which 70% of the coconut gardens have fully recovered in growth, 30% of the coconut gardens are in the recovery stage and have not spread. Of which, 2 districts with large and heavily infected areas, Mo Cay Nam and Thanh Phu, have made good recovery progress.
Head of the Department of Crop Production and Plant Protection (PPP) under the Department of Agriculture and Environment, Vo Van Nam, said: During the campaign, the PPP printed 20,000 leaflets on integrated management measures for land use to coordinate with the Agricultural Extension Center, the Provincial Farmers' Association, and localities to widely distribute and guide farmers to properly implement management measures for early detection and timely prevention. The PPP coordinates with sectors and localities to strengthen propaganda and guide farmers to limit the use of pesticides to protect and effectively promote the source of parasitic wasps (OKS) in the field after release.
The Plant Protection Department is consulting the Department of Agriculture and Environment to estimate the detailed budget for implementing the plan to focus on simultaneously preventing and controlling coconut leafhoppers from the unit's allocated budget to organize field seminars in the second quarter of 2025.
From 2024 to present, the whole province has bred and released 285 million OKS pupae and OKS larvae of SDĐ. Of which, from the beginning of 2025 to present, there are 40 million. Breeding work continues to be accelerated to ensure the number of releases during the peak period of prevention during the dry months of 2025.
Regarding solutions in the coming time, Head of the Plant Protection Sub-Department Vo Van Nam said that the agricultural sector will continue to monitor the results of the implementation of the Plan to simultaneously launch a campaign to prevent and control coconut syphilis in localities, organize field seminars to guide farmers to implement appropriate management measures, and prevent large outbreaks that cause serious damage in 2025. At the same time, focus on OKS breeding, ensure the quantity of release to promote effectiveness during the peak period of syphilis prevention, and actively check and monitor to detect the possibility of recurrence (if any).
“When detecting symptoms of DD damage in coconut gardens, individuals and organizations need to notify local authorities and specialized agencies for timely handling. For DD prevention to be highly effective, it is necessary to correctly assess the level of infection to choose appropriate measures according to the steps. If the rate of mild infection in the coconut garden is less than 20%, step 1 is to prune and destroy infected leaves/leaflets; step 2 is to release OKS multiple times and monitor until there are no new symptoms of damage,” Vo Van Nam, Head of the Plant Protection Department, further recommended.
If the coconut garden is moderately infected (with a damage rate of 20 - 40%), step 1 is to prune and destroy infected leaves/leaflets; step 2 is to spray pesticides once with one of the chemicals instructed in chemical measures; step 3 is to release OKS 14 days after spraying, monitor and release additional chemicals until complete recovery.
If the coconut garden is heavily infected (with a damage rate of over 40%), step 1 is to prune and destroy the infected leaves; step 2 is to spray pesticides twice, 8-10 days apart, with one of the chemicals instructed in the chemical measures; step 3 is to release OKS at least 14 days after the second spray, monitor and continue to release additional chemicals until complete recovery. Particularly for organically cultivated coconut gardens, it is necessary to prune the leaves/leaflets and destroy them by submerging them in water and releasing OKS.
“Mobilizing the prevention of SDĐ is difficult for small-scale planting areas, not for cultivation purposes, or coconut areas along roadsides, planned land, especially in Ben Tre City. Some infected areas have low prevention efficiency because farmers have not properly and fully applied prevention measures according to instructions, the cause is due to high coconut gardens, households do not cut and destroy the leaves before spraying chemicals and do not use the right type of chemicals as recommended…”.
