WEED INFESTATION AND YIELDING OF FIELD PEA AND YELLOW LUPINE DEPENDING ON VARIOUS DOSES OF HERBICIDE MIXTURES
Background. When searching for safer for the environment and effective methods of weed control in the plants of field pea and yellow lupine, possibility of applying reduced doses of soil herbicides should be taken into account.
Material and methods. One-way field experiments carried out in the years 2014–2015 assessed the effect of herbicide mixtures applied at various doses, Afalon Dyspersyjny 450 SC and Command 480 EC, containing linuron and clomazone, on weed infestation and yielding of field pea and yellow lupine. Results. Compared with the control, soil application of herbicide mixtures, Afalon Dyspersyjny 450 SC (linuron) and Command 480 EC (clomazone), at a full dose and at doses reduced by 25 and 50%, decreased the number and weight of weeds, as well as their species diversity, which was reflected in an increased seed yield of field pea, cv. Turnia, and yellow lupine cv. Perkoz. No harmful phytotoxic effect was found in the experiment of the applied herbicide doses containing linuron and clomazone, on emerging plants of field pea and yellow lupine.
Conclusion. Doses of herbicide mixtures containing linuron and clomazone reduced by 25%, and even 50% enable maintaining a low level of weed infestation, and ensure a high seed yield level in field pea and yellow lupine.
