The most important criterion in the application of soil herbicides is the uniform coverage of the soil surface.
Gleber adjuvant reduces the drift of the spray liquid and causes even coverage of the soil, thus reducing the spray rate (less water per hectare).
During soil treatment, the soil is not covered with plants. Then there is a great risk of air movement which can cause the drift of the spray liquid, which causes its uneven distribution in the field and the performance of the herbicide.
The addition of Gleber adjuvant reduces the drift of spray drops. Moreover, this adjuvant increases the concentration of hebicide in the topsoil and limits its penetration into the soil profile.
Weeds germinate mainly in the top layer of soil (approx. 5 cm). Therefore, increasing the concentration of herbicide in this layer, increases its herbicidal effectiveness.
