摘要: DELCHEV, Gr. and A. STOYANOVA, 2015. Stability estimation of some mixtures between retardants anticereal herbicides for grain yield durum wheat. Bulg. J. Agric. Sci., 21: 358–362 The research was conducted during 2010-2012 on pellic vertisol soil type. Under investigation Bulgarian wheat cultivar Progress, which belongs to Triticum var. leucurum. Factor A included the years investigation. B no treated control 3 – Stabilan (chlormequat) 2 l.ha –1 , Flordimex extra (ethephon) 750 ml.ha Terpal (ethephon + mepiquat) . C weeded Scorpio super 100 EC (phenoxaprop-ethyl) 700 Grasp 25 SC (tralkoxidym) 1.2 Topik 080 (clodinafop) 450 weak adhesion required its application with adjuvant Atplus Investigated have not antibroadleaved effect broadleaved weeds in all variants done herbicide Secator OD dose All retardants, their tank-mixtures were tillering stage most increase is obtained by combined use retardant Grasp, Topik. Tank tank are unstable yield. super, technological valuable. They combine high stability relation different years. Application Stabilan, without low estimate could be used crops.
