Explanation
Mechanical weeding is highly effective in controlling annual weeds in vineyards and is widely recognized by farmers as the simplest and most practical alternative to herbicides.
Advantages
Mechanical weeding is highly effective for controlling annual weeds in vineyards.
Drawbacks
Effectiveness is reduced on steep slopes and in high-density vineyards where short vine spacing limits machinery operation. When cover crops are sown in alternate rows, it becomes difficult to control weeds on both sides of the vine row.
Mechanical weeding is both costly and time-consuming, which may limit adoption, particularly for smaller farms.
Under-row mechanical weed control is difficult to perform in hilly vineyards with steep slopes. In stony soils, equipment may be at risk of damage.
This practice can contribute to increased soil erosion, greenhouse gas emissions, and losses of soil organic matter.
Technical Aspects

Technical readiness
This group of techniques is well known, widely available on the market, and easily scalable at the farm level.

Ease and efficiency of implementation
Under-row mechanical weed control can be challenging in hilly vineyards with steep slopes. In stony soils, there is a heightened risk of equipment damage. High-density vineyards with short vine spacing further complicate machinery use. Additionally, when cover crops are sown in alternate rows, it becomes difficult to manage weed control on both sides of the row.

Need for training and education
Demonstration activities are essential to share knowledge about new tools and practices related to mechanical weed control. Training should also address local pedoclimatic conditions to guide farmers in selecting the appropriate equipment and timing for weed management operations.
