    Pest Profile

    • About the pest


      Cotyledons are strong, usually three times as long as wide, with generally uneven leaf halves (Picture 1). The leaves are triangular with a heart shaped base, stemmed, initially bag-shaped pointing downwards (Picture 2). The underside of the leaf and the stem often have a red tint. The leaves are arranged alternately on the stem (Picture 3). The inflorescences are white-green, short-stemmed, non-descript with loose pseudo-spikes. Each plant produces 100-300 seeds. The seeds are three-sided, black, and closely surrounded by brown remainders of the bracts (Picture 4). In soil, the seeds remain viable for approx. 20 years.
