HERBICide DEFENDA EPHEMER

Mechanism of Action

The active substance infringes biosynthesis of structural and enzyme proteins that leads to the destruction of metabolism of a plant organism. It penetrates into a plant through the surface organs (mainly through the leaves) and actively moves through the plant, accumulating in the young meristematic tissues of leaves, stems and the roots. Under the influence of the phenomenon of epinasty, i.e. the accelerated growth of tissues of the top of the leaves, stems and petioles, they become distorted towards the bottom, thickening of the conducting fabrics, which is accompanied by turgor. As a result, thereof the shoots and roots are broken up, the nitrogen, phosphorus, potassium intakes to the plant decrease, and the synthesizing action of the root system ceases. Aqueous exchange is disrupted, turgor is lost, and plants fade and die.

Coverage

Most sensitive weeds:

Weeds of the cross-flowers family, amaranth, self-seeding rape, lambsquarter goosefoot (Chenopodium album), ambrosia, self-seeding poppy, self-seeding sunflower (including persistent to sulfonylureas and imidazolines), Chinese bellflower (Abutilon), common cocklebur (Xanthium strumarum), common arache (Atriplex patulum).

Middle-sensitive weeds:

thistle yellow, Canada thistle (Cirsium arvense), field bindweed (Convolvulus arvensis) (Ephemer is more effective against bindweed than 2.4-D amine salt).

Preparation Properties

Signs of action already appear on the day of treatment. The preparation especially fast shows its effect in the areas where the small precipitations are usually falling.
