False and Stale Seedbeds: The most effective non-chemical weed management tools for cropping and pasture establishment

Globally there is a growing need for non-chemical weed management tools due to multiple and increasing issues with herbicides.  Of the many non-chemical techniques ‘false seedbeds’ stands out due to its efficacy, ease of use, reliability and low cost plus it can be used for any kind of plant establishment from pasture through arable to vegetables.  Contrary to many peoples view of non-chemical weeding as being focused on killing weeds in the growing crop, this is a tillage / cultivation based technique, that can be used for any crop as it undertaken pre-planting.

The final frontier: Non-chemical, intrarow, weed control for annual crops with a focus on mini-ridgers

Non-chemical weeding machinery has made huge advances over the last couple of decades and the combination of modular parallelogram hoes and computer guidance interrow hoeing is now a straightforward field operation.  The final frontier is now intrarow weeding between the plants, and this is being aggressively pushed back with a combination of both high and low tech approaches.  Download this report as a PDF file, or read the full report as an FFC Bulletin article.

Intrarow Soil Thermal Weeding 2013

Intrarow Soil Thermal Weeding (ISTW) is considered to be the only direct non-chemical substitute for herbicides, and that can outperform weed killers in a number of ways including: broad spectrum, i.e. kills all therophyte weeds; has a residual period as long as the crop’s production cycle; can be used in any row crop (economics notwithstanding); has a nil withholding period; has no risk of releasing chemicals into the environment; has exceptional reliability levels (i.e., always works); and has no risk of evolved resistance.
