Maximising yield potential and persistence in pyrethrum through an enhanced understanding of abiotic and biotic stresses (PY12002)

What was it all about?

This project consisted of a number of component studies each addressing the general aim of improving the persistence and productivity of pyrethrum grown for the extraction of pyrethrins.

The need for this project arose because of the continued sensitivity of pyrethrum to many stresses including plant pests, weeds, waterlogging, and multiple herbicides.

The component studies included work on the potential for plant growth regulators to enhance crop vigour, research into the effects of waterlogging and plant density on crop yield and persistence, and a study assessing the extent and control of slug and snail damage in pyrethrum.

In addition, several studies on improved weed management were conducted, as was a study assessing the relative importance of a range of factors that have potential to affect crop yield.

The recommendations from this report are that…

  • While waterlogging remains a problem, growing pyrethrum in raised beds did not offer any advantage that would warrant their installation
  • Growers should continue to plant crops at densities of 30-40 plants per m2 provided fungicides are also applied as recommended

There is insufficient evidence to recommend growth promoter ComCat for pyrethrum production.
