Pest control problems up in Spain
The incidence of insect resistance to pesticides in Spain rose between 2004 and 2006, according to a study from the industry-supported Insect Resistance Action Committee (IRAC). There were 15% more cases in last year's study than in 2004, but from a larger sample. The number of cases per respondent rose 6% to 7.9. Each case represented a reported control problem on one crop in one Spanish province, indicating the insect species and the level of the problem. The IRAC also found that such cases were more widespread. Committee member and technical director of Spanish agrochemical company Aragonese Agro (Madrid), Jaime Ortiz Dorda, presented the findings at the Spanish agrochemical industry event, Las 29as Jornadas, last month.
