Study on the Action of Foliar Herbicides and Herbicide Combinations for Control of Wheat (Triticum aestivum L.) Weeds

Abstract

The action of some foliar herbicides and herbicide combinations for control of common wheat (Triticum aestivum L.) weeds was studied. To that end against the background of soil applied Stomp 330EK New at a dose of 5 l/ha the herbicides Axial 050EK, Granstar 75DF, Derby Super WG, Sekator OD, Lintur 70WG, and the tank mixtures of Axial with the other herbicides applied in the tillering phenophase of the crop were studied. The species composition and density of weeds was assessed using the quantitative method prior to treatment and after herbicide treatment on days 5, 15 and 30, by constant metering. The herbicide Lintur 70WG and its combination with Axial 050EK had the fastest initial effect. The highest herbicidal effect (99.5%) against annual monocotyledon and dicotyledon weeds showed the combination of Derby Super WG 33 g/ha + Axial 050EK - 900 ml/ha. Very good was the effect of the other herbicidal mixtures between anti-broadleaf herbicides and the graminaceous herbicide Axial 050. All applied herbicides and herbicide mixtures showed a very good after-action on weeds.

“…This was reflected positively in reducing their number at a high rate compared to the weedy control treatment. This result agreed with what was indicated by (3,12,20,24) who provided evidence to support the claim that using pesticides significantly reduces the amount of weeds.…”
