THE EFFECT OF SOME HERBICIDES UPON WEEDS FROM THE SUNFLOWER CULTURE.

The paper presents the experimental results obtained in the year 2020 regarding the individual effect of five weed killers, used for the control of weeds at the sunflowers crops, as well as that action in association with two other herbicides: Sencor applied in a quantity of o,4 kg/ha and Gesagrade 50 applied in a quantity of 3 kg/ha. As concerns the effect of the individual application of each weed killer, on the first place we can put Alachlor with an average production increase of 6,95 q/ha or by Treflan with an average production increase of 6,80 q/ha, or 33,0% as compared to the witness. The weed control by use of herbicides, is a very effective method, this way eliminating the hand hard work used for maintaining the growing. [ABSTRACT FROM AUTHOR]
