Mechanical weeding in large-scale crops
Mechanical weeding in large-scale crops helps sustainably reduce weed pressure, limit seed production and decrease dependence on herbicides. This approach is part of a broader agronomic strategy, in both organic and conventional farming.
Limit seed production
Cutting or extracting weeds before they produce seeds helps slow their spread and limits the enrichment of the soil seed bank.
Reduce weed pressure
Mechanical weeding complements other agronomic practices and helps control weeds without relying solely on chemical solutions.
Adapt intervention to field conditions
Topping, mechanical weed pulling or cover crop management: several solutions can be used depending on the crop and the level of weed pressure.
Why integrate mechanical weeding into your cropping strategy?
Mechanical weeding consists of acting directly on weeds using tools capable of cutting them, pulling them out or limiting their development.
In large-scale crops, this approach helps better control problematic weeds while reducing the selection pressure associated with chemical solutions.
This method is particularly relevant when certain weeds grow above the crop, become difficult to control or risk permanently increasing the field seed bank.
It also allows farms to adopt a broader agronomic approach based on prevention, observation and the complementarity of different practices.
Weed cutting: an effective response against weeds growing above the crop
Weed cutting consists of cutting weeds that grow above the crop canopy. This technique is particularly useful when certain dominant plants grow taller and risk producing seeds.
By removing the upper part of the plant before seed production, the weed cutter helps slow the spread of weeds and supports a sustainable weed management strategy.
Bionalan offers two ranges of weed cutters to suit different farming contexts: The Eco Selac, designed for farms looking for a simple, reliable and cost-effective solution, and The Selac, developed for large working widths, high power and high field capacity.
This approach is particularly valued in organic farming, but it is also of interest to conventional farms seeking to reduce herbicide use.
Pull weeds out by the root
Some machines grip and extract weeds to limit regrowth, particularly in low-growing and sensitive crops.
Manage cover crops and biomass
Mechanical destruction of cover crops helps manage intercrops and supports certain no-tillage strategies.
Adapt the tool to the objective
The choice depends on the type of weeds, the crop, the intervention stage and the farm’s agronomic strategy.
Which machines for mechanical weeding?
Depending on your objectives, several types of equipment can be used to build a coherent strategy for weed and cover crop management.
