Mode of action
Florasulam inhibits biosynthesis of indispensable amino acids by inactivation of acetolactate synthase enzyme. 2.4-D contained in the preparation acts as an auxin like growth inhibitor. The preparation has a systemic effect and quickly (within 1 hour) penetrates into and spreads within all parts of weeds, including roots, thus blocking cell growth in young tissues.
Protective period
The duration of herbicidal effect depends on preparation dose, weather conditions, species sensitivity and weed age. The best result is achieved when treating 5-10 cm annual dicotyledonous weeds and perennial weeds at rosette stage.
Speed of action
Weeds on plantings cease growing within a day after treatment. First signs of exposure become visible as early as in 3 or 4 days. Depending on weed kind and weather conditions, total extinction of weeds takes place in 2 or 3 weeks after treatment.
Range of inhibited weeds
Annual and perennial dicotyledonous weeds
Sensitive species: ragweed, Canadian thistle, yellow thistle, speedwell (species), pepper plant (species), charlock, black bindweed, bankweed, tansy mustard, common fumitory, yellow cress, satin flower (common chickweed), Tartarian lettuce, copper rose, pigweed, common dandelion, field sow thistle, rough sow thistle, houndsberry, caseweed, catch weed, wild radish, chamomile (species), amaranth (species), dish mustard, day-nettle species, and others.
Compatibility with other pesticides
Compatible with many herbicides for protection of cereal crops, including Granat, Fenizan, Zinger, Ovsugen Express, Ovsugen Super, and others, as well as with insecticides, fungicides, and agrochemicals. Before use, check the mix for compatibility and phytotoxicity with regard to the crop treated.
