Micropropagation and induction of autotetraploid plants of Chrysanthemum cinerariifolium (Trev.) Vis
In Vitro Cellular and Developmental Biology - Plant, 2007Rapid propagation technology was established and optimized in vitro for Chrysanthemum cinerariifolium (Trev.) Vis., an important botanical insecticide plant with a huge international market. A large number of buds could be induced directly from epicotyl and hypocotyl explants on Murashige T; Skoog F. J. Plant. Physiol.

Spacing and nitrogen studies in pyrethrum (Chrysanthemum cinerariifolium)
The Journal of Agricultural Science, 1982Pyrethrum flowers are widely used in different insecticidal formulations for controlling household insects and crop pests. The quick knock-down effect on insects, the low mammalian toxicity and the rapid decomposition of pyrethrins in the soil make it an ideal and safe insecticide. The flower yield in pyrethrum is influenced by plant population density

AbstractPyrethrum [Chrysanthemum cinerariifolium (Trevir.) Vis.] is an important “green pesticide” crop widely used for insect control on plants and for humans. Pyrethrum flowers have the highest Pyrethrin I/Pyrethrin II ratio (%Py) and are harvested at specific stages to maximize yield. Selection for correlative early seed germination and flowering in

The Journal of Supercritical Fluids, 2017
Abstract In this work, a comparison between three extraction processes, including traditional maceration in n-hexane and ethyl alcohol, supercritical fluid extraction (SFE) and cyclically pressurized extraction known as rapid solid-liquid dynamic extraction (RSLDE), has been carried out for the extraction of pyrethrins, predominantly nonpolar natural

Croatia is the homeland of Dalmatian pyrethrum, in the 20-ties of 20 century it had a production on 2000 hectares. With comparative merits (clear environment and favourable climatic conditions) comparing to other European countries, Croatia has a great possibility to be a centre of eco agriculture and eco tourism, what is also a strategic goal of ...

The Rice Weevil Sitophilus oryzae is one of the most destructive primary storage product pests worldwide and is known for attacking stored grains such as wheat, corn, oats, and rice. A wide variety of agricultural chemicals are being used as pesticides but sole reliance on these chemical-based insect-killers is not safe and sufficient.
