Pyrethrum

{Chrysanthemum cinerariaefolium}

Boron Deficiency in Pyrethrum

Boron deficiency causes the development of misshapen and malformed flowers and apical dieback in pyrethrum. Ray florets may be reduced to one third their normal length. They have ragged tips and they may be formed on only part of the circumference. In some cases, ray florets may be completely absent.
