  • 1. Roundup Ready® Maize and till d tillage practices ti Prague , June 2011 Ivo Brants Regulatory Sciences Lead, EMEA
  • 2. Controlling weeds has been a challenge throughout the history 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 1930’s which led to the formation of NRCS and the move towards conservation tillage1930’s 1940’s 1950’s 1960’s 1970’s 1980’s 1990’s 2000’s2 Photo courtesy of USDA Natural Resources Conservation Service
  • 3. Technological advances have increased the number of tools available for controlling weeds • The invention of synthetic chemical herbicides in the 1950 s 1950’s and 1960’s offered 1960 s growers a new set of tools for controlling weeds • Roundup and other broad spectrum herbicides offered farmers a new burndown tool1930’s 1940’s 1950’s 1960’s 1970’s 1980’s 1990’s 2000’s3 Photos courtesy of USDA Natural Resources Conservation Service
  • 4. Biotechnology has provided growers with additional too s their tools in t e quest to co t o weeds control eeds Herbicide tolerant crops have Growers have adopted these enabled growers to use broad crops broadly due to several spectrum herbicides in crop p p key benefits to their weed for greater weed control control systems Efficacy Convenience Cost1930’s 1940’s 1950’s 1960’s 1970’s 1980’s 1990’s 2000’s4

Major Weeds in European Maize Production (Bi)Annual dicots Annual grasses Perennial dicots Perennial grassesAmaranthus retroflexus Alopecurus myosuroides Cirsium arvense Agropyron repensCapsella bursa-pastoris Digitaria sp. Convolvulus arvensis Cynodon dactylonChenopodium album Echinochloa crus-galli Cyperus rotundusDatura stramonium Poa annua Sorghum halepense g pGalium aparine Setaria sp.Lamium sp. Major weed control strategies in European maize production:MatricariaM t i i sp. • Around 50 maize selective active substances on Annex 1 of EU DirectivePolygonum sp. 91/414. General trend goes to less compounds in the future.Solanum nigrum • Between 14 and 33 active substances registered per member stateStellaria media • Herbicides are usually mixed to control the local weed flora • 1 or 2 (seldom 3) herbicide applications per maize cropVeronica sp. • Application timings differ widely. There is a tendency towards pre-Xanthium sp. emergence applications i S th li ti in Southern E Europe and t d towards post- d t emergence treatments in Northern Europe.Geranium sp.

  • 9. Roundup Ready® Maize Weed Control Concept 1 2. Roundup (max. 1080 g ae) 1. residual herbicide pre-emergence 3 6 8 corn leaf stage g weed sensitive period1. Apply any registered residual maize herbicide at reduced rate before emergence of corn2. Control later emerging weeds with Roundup (max 1080 g ae) by respecting a) ) weed height: less than 10 cm g b) corn growth stage: latest at 3 leaf stage 9

Roundup (max. 1080 g ae) 2 R d 1. tank mix Roundup (max. 1080 only if neccessary g ae) and residual herbicide 3 6 8 corn leaf stage weed sensitive period1. Apply a tank mix of Roundup and a compatible residual maize herbicide (at reduced1 rate) at 3 leaf stage of corn2. In case of high weed pressure apply Roundup again In both cases the application timing is triggered like in concept 1 by weed height (less than 10 cm) and crop growth stage 12

Depending on weed pressure apply Roundup a second time latest at 8 leaf stage of corn In both cases the application timing is triggered by weed height (less than 10 cm) and crop growth stage(the pure Roundup concept is a prerequisite to register Roundup over the top in Roundup Ready maize) 14
  • 15. Roundup Ready® Maize Weed Control Concept 4 Roundup (max. 1440 g ae) 8 corn leaf stage weed sensitive periodEspecially in warmer climates the late control of perennial weeds like Convolvulus arvensis isa major concern in maize productionThe Roundup Ready system in maize offers a new solution for this problem Start with concept 1 to 3 at max 720 g ae of Roundup at the 1st application Apply 1440 g ae of Roundup latest at 8 leaf stage of corn when perennial weeds have sufficient leaf area for take up of glyphosate 15
