Controlling weeds has been a challenge throughout the history of agriculturehistory of agriculture
• Prior to chemical herbicides, tillage and other mechanical methods were the primary weed control tools
• Extensive tillage was a contributing factor to the Dust Bowl in the 1930’s which led to1930 s which led to the formation of NRCS and the move towards conservation tillagetillage

Technological advances have increased the number of tools available for controlling weedstools available for controlling weeds
• The invention of synthetic chemical herbicides in the 1950’s and 1960’s offered 1950 s and 1960 s offered growers a new set of tools for controlling weeds
• Roundup and other broad spectrum herbicides offered farmers a new burndown tool

• Around 50 maize selective active substances on Annex 1 of EU Directive91/414. General trend goes to less compounds in the future.
• Between 14 and 33 active substances registered per member state

• Herbicides are usually mixed to control the local weed flora
• 1 or 2 (seldom 3) herbicide applications per maize crop
• Application timings differ widely. There is a tendency towards pre-li ti i S th E d t d tXanthium sp.

Weeds represent a significant threat to agricultural productivity and cause losses even with control efforts

The Positive impacts of no-till system ‐ 90% less soil erosion.‐ 40% less fuel use.‐Maintenance or improvement of the soil organic matter.‐ Increase in soil fertility /biodiversity (chemical, physical and biological).Higher water use efficiency‐ Higher water use efficiency.
‐ Lower production costs.‐ Higher production stability and yield potential.
TANGIBLE BENEFITS FOR THE FARMER
‐ Better soils, higher capability to produce food and energy.‐ Less competition for drinkable water (strategic resource).p ( g )‐ Higher water quality (lower erosion and contamination risk).‐ GHG emissions reduction, positive impact on climate change.‐ Less pressure on HCV and fragile areas (by production increase).Possibility of producing in degraded and/or fragile lands without the known risks of‐ Possibility of producing in degraded and/or fragile lands without the known risks of

Roundup Ready® Maize in Argentina
‐ Adopted by small (< 500 ha), medium, and large farmers (> 5000 ha), since 2004.
‐ 70% of the crops in Argentina are under no‐till.‐ 47% of the corn is RR (mainly NK‐603, and the rest is GA‐21),
offered by around 10 seed companies.y p
