Implications of genetic variation within pyrethrum (Chrysanthemum cinerariifolium and Chrysanthemum coccineum) germplasm: Intra‐ or inter‐specific hybridization as mechanisms to circumvent genetic bottlenecks

Crop Science
AbstractThe University of Minnesota (UMN) Pyrethrum Breeding Program has been developing Chrysanthemum cinerariifolium with increased levels of Pyrethrin I/Pyrethrin II ratio (%Py) for over a decade. Pyrethrum is an economically important “green pesticide,” producing %Py in glandular trichomes, with the highest concentration in the flowers.

Supercritical Extraction of a Natural Pyrethrin-Rich Extract from Chrysanthemum Cinerariifolium Flowers to Be Impregnated into Polypropylene Films Intended for Agriculture Applications

AppliedChem, 2022
The extensive use of synthetic pesticides and their addition to the field presents significant environmental problems that must be minimized. The use of natural insecticides and their addition using techniques that minimize their impact in the field are widely studied by the current scientific community.

Pyrethrum (Chrysanthemum cinerariifolium) Flowers’ Drying Conditions for Optimum Extractable Pyrethrins Content

Journal of Plant Studies, 2020
Pyrethrum flowers of the genus Chrysanthemum cinerariifolium are grown in Kenya by small scale farmers for extraction of pyrethrins, a natural insecticide’s active ingredient. Pyrethrins are classified in two groups, Pyrethrins I and II, and are degradable when exposed to air, moisture and high temperatures.

Chinese star anise (Illicium verum) and pyrethrum (Chrysanthemum cinerariifolium) as natural alternatives for organic farming and health care- A review

Australian Journal of Crop Science, 2020
Botanical insecticides keep attracting more attention from environmental and small farmers worldwide as they are considered as a suitable alternative to synthetic insecticides. The outstanding properties of pyrethrum include rapid action, low mammalian toxicity, broad spectrum of activity, lack of insect immunity, lack of persistence and of course ...

The chemical evaluation of pyrethrum flowers (Chrysanthemum cinerariifolium). The extraction of the flowers for analysis and the preparation of colourless concentrates of the pyrethrins

The Journal of Agricultural Science, 1941
1. Biological trials have been carried out to determine the efficacy of petroleum ether as solvent for the extraction of pyrethrum flowers for analysis. 95% of the toxic material was extracted from flowers one year old after only 3 hr. percolation. An extraction period of 8 hr. with petroleum ether is suggested.2.

CmERF5-CmRAP2.3 transcriptional cascade positively regulates waterlogging tolerance in Chrysanthemum morifolium. [PDF]

Plant Biotechnol J, 2023
Summary Waterlogging stress affects plant growth by limiting root respiration and reducing yield and economic value. Therefore, identifying genes involved in regulating waterlogging stress is vital. This study reports the ethylene‐responsive VII transcription factor (CmRAP2.3) in the chrysanthemum.
