Research on some technical measures to immediately replant Coffea canephora Pierre var. robusta coffee trees in Dak Lak province

Recommendation

1. Before replanting Robusta coffee, use the active ingredient Ethoprophos + Copper hydroxide to treat the soil to reduce the density of nematodes and harmful fungi. During the basic construction phase, apply a combination of chemical and biological measures such as Vimoca 10G + TKS-NEMA to prevent nematodes and harmful fungi. However, because the active ingredient Ethoprophos 94% (Vimoca 10G) is highly toxic and has residual residues in the product, it is possible to use biological active ingredients (Tervigo 20EC + Trico-VTN + MapLogic 90WP) to prevent nematodes combined with the use of wild sunflower powder (fertilization amount 1,000 g/tree in the first year and 2,000 g/tree in the second year) to minimize the impact of soil pollution.

2. Use 34/2 material as rootstock for recognized Robusta coffee lines/varieties to replant right on the liquidated gardens to help reduce the rate of yellow leaves and dead trees to improve replanting efficiency. In addition, it is possible to integrate the treatment of wild sunflower powder at a rate of 1,000 g/tree in the first year and 2,000 g/tree in the second year to reduce the density of nematodes and harmful fungi.

3. The research results were only conducted on Robusta coffee trees in the basic construction stage from new planting to 24 months. Therefore, it is necessary to continue monitoring and evaluating the effectiveness of technical measures in the next 2 years to ensure a reliable scientific basis before recommending the application of this research result.
