- Abstract
The investigation was carried out during the period 2015 - 2016 at the experimental field of the Maize research institute – Knezha on typical chernozem. The following variants were included in the experiment: Zero control K0 – without treatment, weed infested in natural background, control without herbicides K1 – economical with two manual weedings, without weeds, Merlin 750 VG– 12.5 g/da, - 200 ml/ da, Ekip SK - 250 ml/da, Bazis 75 DF - 2.5 g/da. The tested herbicides showed a high selectivity to maize. Herbicide Merlin 480 SK (izoxaflutol) – 12.5 g/da applied after sowing, before crop emergence and Ekip SK (foramsulfuron, antidote) in doses 200 ml/da and 250 ml/da, inserted 4-5 plant leaf, shown a good herbicide effect. In the conditions of the field experiment, the studied preparations destroyed from 56.09 to 65.96% of the weeds, which averted the initial weed infestation at the experimental plots. A very good effect against johnson grass was reported after treatment with Bazis 57DF (rimsulfuron + thifensulfuron), which destroys up to 96% of the johnson grass from seeds and up to 90% of the johnson from rhizomes.
