Mechanical weeding against weed control
The effectiveness, measured
Time horizon: Immediate
Why it works
It is the direct means of controlling under-row weeds where herbicide is banned, keeping competition in check.
What to measure for this pairing
Why this problem matters
Under organic rules synthetic herbicides are prohibited, so under-row weed control becomes one of the biggest operating costs. Management is mechanical, physical and agronomic.
Mechanical weeding in the row, a competitive cover in the inter-row and mulch are the main levers. The challenge is to control competition for water and nutrients without over-tilling or damaging the vines.
Problem indicators
Certification & rules: The absence of herbicide is an absolute requirement of organic certification.
How to apply the means
- 1Choose the intercep tool suited to the soil and vineyard.
- 2Intervene at the right soil-moisture window.
- 3Combine with mulch and cover to cut passes.
- 4Log passes and herbicide-free area treated.
Frequently asked
Doesn’t mechanical weeding damage the vines?
Modern intercep tools with a feeler retract from the trunk automatically. The right setup and speed minimise any risk.
How do I cut the number of passes?
By combining with row mulch and a competitive inter-row cover, which suppress weeds and reduce the need to weed.
