- Abstract
- Glyphosate is the world's most widely used herbicide, with many
registrations in agricultural, urban and semi-natural environments. Glyphosate is an
important tool especially for broad-spectrum weed control and inter-row vegetation
management in perennial crops like olive and citrus groves, orchards and vineyards.
Despite the frequent use in these crops, there are only a few confirmed cases of
glyphosate resistant weed populations in Europe. The first reported European case
dates back to 2004 and involved four populations of Conyza bonariensis found in
southern Spanish olive groves. The glyphosate rates required to control resistant
populations were 7 to 10 times higher than those needed to control the susceptible
populations. In 2006 a resistant population of C. canadensis was reported in southern
Spain while another one was claimed in the Czech Republic in 2007. The resistance in
Czech Conyza is currently still under investigation. Recently glyphosate-resistant
Lolium rigidum was found in French vineyards (2005 and 2007) and in Spanish citrus
groves (2006), while resistant L. multiflorum was identified in Spanish olive groves
(2006). New cases of resistant Lolium spp. are reported from Italian vineyards and
olive groves. In all these cases Lolium plants were not controlled at recommended
glyphosate field rates. Although glyphosate resistant weed populations in Europe are
only a few, the sole reliance on glyphosate for weed control especially in perennial
crops bears the risk of selecting more resistant populations. Resistance management
should be based on principles of Good Agricultural Practices and Integrated Weed
Management:
- use the right rate at the right time;
- apply glyphosate when the plants are more susceptible and the environmental
conditions are favourable for its uptake;
- integrate herbicides with different mode of action (e.g. a selective or residual
herbicide) and mechanical weed control in the weed control program.
The new EU legislation on plant protection products is likely to decrease the number
of active ingredients and herbicidal mode of actions available for weed control and
therefore introduces new challenges for managing weed resistance. (literal)
