Ronstar is a residual herbicide intended to prevent the emergence of a variety of annual weeds and to eradicate by contact types of weeds in vegetables, in flowers and in fruit trees and ornamental trees. Thanks to its low solubility in water, the preparation accumulates in the top layer of the soil (5 cm). Sprouts that move through the treated layer are eradicated. The preparation is absorbed into the plant through the plumule. Its absorption through the roots is miniscule and negligible.

Key Indicators
- Broadleaf annual weeds and grasses
Mode of Action
- Pre-emergence effects are obtained at germination by contact with oxadiazon-treated soil particles. The development of the shoots is stopped as soon as they emerge - their tissues decay very rapidly and the plant is killed. When the soil is very dry, the pre-emergence activity is greatly reduced. Post-emergence effect is obtained by absorption through aerial parts of weeds which are rapidly killed in the presence of light. The treated tissues wither and dry out.
