pyrethrum (Roy, Ghosh and Chopra, 1941). The important point which came to light may be recapitulated. Pyrethrum prepared in the form of an extract by heating the powder in water or mixed with white vaseline proves fatal to lice, but fails to act on nits. This necessitates the continuation of the treatment during the whole period extending over the incubation period of eggs. Observations made i...

Background: As the state of Punjab has become endemic for dengue, this study was planned to determine susceptibility status two different classes adulticides and VGSC gene polymorphism in domain II Aedes aegypti. Methodology: Adult bioassays were performed with pyrethrum, deltamethrin malathion as per WHO protocol. AS-PCR sequencing carried out detect V1016G Kdr (Knockdown resistance) mutations...

Pyrethrum is derived from the dried flowers of the plant Tanacetum cinerariifolium. The name given to the active insecticidal components of the dried flowers is "pyrethrins". Tasmanian pyrethrum production is among the most innovative, high-tech agricultural industries in the world. With an output that nearly quadrupled since 1996, Botanical Resources Australia (BRA) now supplies more then 30% ...

Advance inoculation of the tomato cv. Celebrity or the pyrethrum clone 223 with host-incompatible Meloidogyne incognita or M. javanica elicited induced resistance to host-compatible M. hapla in pot and field experiments. Induced resistance increased with the length of the time between inoculations and with the population density of the induction inoculum. Optimum interval before challenge inocu...

Pyrethrum is a perennial herbaceous plant endemic to the eastern coast of Adriatic Sea, and introduced in large areas nearly all continents, where it cultivated for industrial extraction pyrethrins. Pyrethrins are group six closely related monoterpene esters, widely used as natural insecticides. The world production pyrethrins lower than market demand, wider introduction this crop within Medite...

Scott, J. B., Gent, D. H., Pethybridge, S. J., Groom, T., and Hay, F. S. 2014. Crop damage from Sclerotinia crown rot and risk factors in pyrethrum. Plant Dis. 98:103-111. Sclerotinia crown rot, caused by Sclerotinia sclerotiorum and S. minor, is a prevalent disease in pyrethrum fields in Australia. Management involves fungicide applications during the rosette stage of plant development from au...
