Avicta® is a seed treatment with the active ingredient abamectin.
Avicta® is sold with an insecticide/fungicide seed treatment combination as Avicta® Complete Beans. Abamectin is a natural fermentation product of the soil bacterium Streptomyces avermitilis. The compound disrupts the nematode nervous system (by affecting chloride channels in nematode nerve cells, to be specific). Avicta® is not taken up by the plant (that is, it is not systemic), but it moves on the root surface as the root system develops from the seed.
