- Abstract
In the winter wheat vegetation period of 2019/2020 a field experiment with Sekator OD (100 g/l amidosulphuron + 25 g/l iodosulfuron + 250 g/l mefenpyr-diethyl) was conducted. The trial was situated on the experimental field of the Agricultural University of Plovdiv, Bulgaria. Variants of the trial were: 1. Untreated control; 2. Sekator OD - 0.10 l ha-1; 3. Sekator OD - 0.15 l ha-1 and 4. Sekator OD - 0.20 l ha-1. The herbicide application was performed in tillering stage (BBCH 21-29) in spring. For the study's purposes, the "Avenue" variety was grown. As well as the efficacy and the selectivity of the herbicide product, several quantitative and qualitative indicators were evaluated. The highest efficacy against the existing broadleaf weeds for the rate of 0.20 l ha-1 was recorded. There were no visual phytotoxic symptoms for the crop for any of the evaluated rates. By using the statistical criterion of Student Test, a positive and significant increase in the values of stem height at the rate of 0.10 l ha-1 and the number of ears at the rate of 0.20 l ha-1 were found.
