Aspects of Winter Wheat Physiology Treated with Herbicides

Environment agriculture: crop plants, weeds and soil can occur by applying enough strict rules of chemical treatment. These are: the correct dosages, time intervals, implementing optimal correlation unwanted flora and plants phenophase development. Wheat proceed too easy to broadening the range of herbicides, from different causes. Applying too early (even in autumn) and late- as often happens in practice, produce change normal physiology of wheat plants.From recent research (Pascal & Scala, 1999), showed that herbicide metabolism pathway can induce negative phenomena, expressed in particular by modifying of winter wheat plant, fruit, grain. This is the case of hormonal herbicides applied late (bout stage) and again bromoxynil (PS II inhibitor) in the autumn to the emergence of the first tiller. The data highlight the very obvious loss of production for hormons and relative for bromoxynil.
