Benefits
-
Wide range of use on different cultures -
Effectively fights almost all types of annual and perennial grass weeds
-
Quickly absorbed by weeds
-
Destruction of not only the aerial part, but also the root system of weeds
-
High activity at different temperatures -
There is no need to add surface-active substances, since they are already in the composition of the drug
Mode of action
The drug is quickly absorbed and easily moved, accumulates in the nodes and underground rhizomes of perennial grass weeds, completely destroys the meristematic tissues of the rhizomes. In addition to surface application activity, it is effective in combating the secondary growth of rhizomes of perennial weeds. Weeds die in 7-10 days.
Compatibility
The drug is well compatible with Blyskavka, Ratibor bio insecticides; Osotyn herbicides; fungicides Source, Wizard. If there are doubts about compatibility with another drug, we recommend conducting a preliminary test.
Additional Information
The drug does not work on dicots (broad-leaved crops)! Not toxic to bees. Manual work on crops should be carried out no earlier than 7 days after processing, and mechanized – after 3.
Features of use
Spraying is carried out during the growing season of the crop. The working solution must be used within a few hours after preparation. The most favorable time to apply the drug is in the morning or in the evening. In order to obtain maximum efficiency, it is necessary to ensure sufficient and uniform spraying of the aerial part of the plants. Weeds die 1–2 weeks after treatment. During this time, they do not suppress the culture. The preparation is ready for use and there is no need to add a surface-active substance to the working fluid. The most favorable period for using the drug Oberih is the presence of 1–2 leaves in annual grass weeds and from 2–4 leaves to the tillering phase at a height of 10–15 cm in perennial weeds. If the weather was dry and hot before application, the consumption rate of the drug Oberih, like any herbicide, should be taken higher than the average, because the weeds are in a state of stress, their covering tissues are thickened and the penetration of the drug into the plants is difficult. If the weather was warm and humid before use, the rate of consumption may not be increased. With a long-term decrease (increase) in temperature, the effect of treatment manifests itself later. After optimal conditions, the herbicidal effect of the drug is resumed.
