Field studies were conducted in 2007–2009 at the Research Field Experimental Station of Institute of Plant Protection at Winna Góra. The aim of the studies was to determine the efficacy of herbicides trifluralin and clomazone applied with adjuvants Lenmix 800 EC and Atpolan 80 EC for weed control in winter oilseed rape. Adjuvant Lenmix 800 EC used with trifluralin increased weed control. On the other...
Biological efficacy of herbicides: propoxycarbazone-sodium (Attribut 70 WG) and sulfosulfuron (Apyros 75 WG) applied with adjuvants was estimated in the field, greenhouse and laboratory experiments. An addition of adjuvants to herbicides Attribut 70 WG and Apyros 75 WG had a positive influence on physical characteristics of tank mixture, herbicidal effect, and the increase of winter wheat grain yield...
Field experiments were conducted to determine the influence of adjuvants on fenoxaprop-P-ethyl bioefficacy against wind grass (Apera spica-venti), wild oats (Avena fatua) and barnyard grass (Echinochloa crus-galli). The commercial product Puma Universal 069 EW, which contains 69 g/l of fenoxaprop-P-ethyl, was applied with different adjuvants in springtime in winter barley, winter triticale, winter...
The aim of the experiments was to evaluate the effect of Sekator 6,25 WG used for broad leaved weeds control in winter and spring cereals. Sekator 6.25 WG herbicide is composed of iodosulfuron 1.25%, amidosulfuron 5% and mephenpyr diethyl 12.5%. The field trials were conducted over the period 1997-1999 at experimental station, which belonged to the Institute of Plant Protection. The results showed...
Field experiments were conducted to determine quizalofop-P-tefuryl (Pantera 040 EC) efficacy for control of couchgrass (E. repens) at crop rotation peas-spring cercals. The results showed that herbicides applied at 4-8 leaf stage of E. repens enhanced weed control effect. Subsequent treatments i.e. at 10- 12 leaf stage of E. repens were less effective. In the following years, the yield of spring cereals...
