Effectiveness of dicamba + prosulfuron and reaction of sugar maize (Zea mays ssp. saccharata Koern.) varieties

Summary.

The aim of this research was to evaluate the reaction of 10 varieties of sugar maize on the active substances dicamba + prosulfuron and assess the effectiveness of this mixture.
An experiment was carried out at the Experimental-Didactic Station at Swadzim in 2008-2010. Ten sugar maize hybrids were studied. Spraying herbicide with crop oil concentrate was performed at the five- to six-leaf stage. A week after the herbicide application, weeds were collected and weighed. On this basis, the effectiveness of active substances was measured (%). The crop was evaluated visually in five periods on a 1-9 scale. After the plants came to milk ripeness, cob yield (t·ha-1), share of first class cobs (%), cob length (cm), number of grains per cob and cobs per hectare were defined. It was found that the average effectiveness of the herbicide was 53-60% against the three examined weed species, namely ‘Garrison’, ‘GSS 8529’ and ‘Rustler’. Transient, phytotoxic action of active substances on the three sugar maize varieties was observed. Dicamba + prosulfuron affected the growth of cob yield, share of first class cobs and cob length. The mixture had no effect on the number of grains per cob and number of cobs per hectare.

Key words: dicamba, herbicide effectiveness, maize, prosulfuron, sensitivity
