Control of Avena Fatua Species (Wild Oat) - a Weed in Expansion in Banat Area

Wheat is considered the largest agricultural crop acreage worldwide.More than 50% of human caloric needs is ensured by grain products.The presence of different species of weeds in cereals causes loses between 15 -20% and even 60-80% of the crop in the absence of control measures.The most dangerous monocotyledonous species present in this culture are Apera spica -venti (wind grass), Avena fatua (wild oat) and Bromus sp., they produce huge damage to both varieties for consumption and seed lots.Chirilă C. ( 2001), states that the species Avena fatua is one of the 132 species considered problem, namely: direct harm and high on production; has a high resistance to agro-chemical control measures; and the number or rapacity reduce the positive effect of some production factors.This study aims to provide new data on chemical control of Avena fatua in agroecosystems species of wheat.Research on chemical control of Avena fatua species were conducted in Teaching and Research Station, belonging to the University of Agricultural Sciences and Veterinary Medicine "King Michael I of Romania" in Timisoara.Experience included 12 variants, in three repetitions, placed after the randomized blocks method.Variants differ by herbicides applied.Efficacy of herbicides in control of species Avena fatua had values between 60-85%.The best herbicide used against Avena fatua proved to be Axial One EC (control rate 85%).
