Dorin Jurca, Gheorghe Popescu
he objective of this work was the establishment of the value implication of the European maize gimlet in the dissemination and amplification of the pathogen within the system (Fusarium roseum). Regarding the movement of the fungus Fusarium roseum in the conventional and transgenic maize fields, we may say that:  - in 2008 , in the conventional maize, fusariosis movement was performed by wind (9.34%) and by the insect Ostrinia nubilalis, the Fusarium percentage of 41.93% belonging to this; - in the case of the Yield Gard maize, fusariosis was moved by wind, which spred the spores in the attack of 9.34%, a percentage that can be due to anemochoria (2008); - in 2009 , in the case of the genetically modified maize (MON 810), the fusariosis was of anemochoric type and it was performed in an aggression mean of 7.7%, while in the conventional maize, it was performed with a plus of 23.9%, with the help of zoochoria, concretely due to the European maize gimlet; this expression refers to the attack mean of the four conventional maize hybrids – 31.6% and 7.7% - Yield Gard-type maize (MON 810).
