Completed project
Maximising yield potential and persistence in pyrethrum through an enhanced understanding of abiotic and biotic stresses (PY12002)
Publication date: January 18, 2017
Delivery Partner: Botanical Resources Australia Agricultural Services
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…
There is insufficient evidence to recommend growth promoter ComCat for pyrethrum production.
This project was a strategic voluntary levy investment in the Hort Innovation Pyrethrum Fund
