Abstract:

Six pyrethrin esters were separated from whole pyrethrum by using high performance liquid chromatography on a silica column. Dilutions of individual esters were applied topically to house flies (Musca domestica L.) and compared to whole pyrethrum and transpermethrin. LD50's averaged from two significant dosage-mortality regressions per chemical were in ascending toxicity: Cinerin I (1.77 μjg/fly), jasmolin I (1.28 μjg/fly), pyrethrin II (0.49 μg/fly), jasmolin II (0.46 μg/fy). cinerin II (0.43 μg/fly), pyrethrin I (0.20 μg/fly)&gt; 25% pyrethrin extract (0.11 μg/fly) and trans-permethrin (

Abstract:

Pyrethrin is a specialized metabolite of Dalmatian pyrethrum (Tanacetum cinerariifolium (Trevir.) Sch. Bip.), Asteraceae, known worldwide as an effective bioinsecticide. It consists of six active compounds: Pyrethrin I and II, cinerin I and II, and jasmolin I and II. Pyrethrin accumulates mainly in the flower heads and its content depends on numerous factors, such as the flower developmental stage. This study aims to investigate the accumulation patterns of six pyrethrin compounds in the flower heads of Dalmatian pyrethrum over the eight developmental stages (FS1 to FS8), and to make a compari

Abstract:

Nowadays, immediate environmental friendly solutions such as the use of biopesticides and other methods to control and manage pests are well needed. They are imperative due to the continuous accumulation of toxic residues from synthetic insecticides into the environment, the contamination of global agro-ecosystem and resistance of certain insects and pathogens. The global renewed interest of botanical pesticides does not leave aside Turkey. Thus, many environmental reports pointed out contaminations in different regions of Turkey by chemical pesticide residues, like lambda-cyhalothrin in some

The main chemical compounds in pyrethrum flower extract obtained by supercritical fluid extraction (SFE) were identified by GC-MS. Peak area normalization was used to determine relative percentage content of the compounds. The results showed that the main chemical compounds in pyrethrum flower extract were β-farnesene, β-cubebene, ethyl palmitate and ethyl linoleate, besides six pesticidal active compounds of pyrethrins that were cinerin I, jasmin I, pyrethrin I, cinerinII, jasminIIand pyrethrinII.

Abstract:

Pyrethrum (Tanacetum cinerariifolium) is one of the most important industrial crops for the extraction of pyrethrins, which are natural insecticidal compounds. Progress in pyrethrum molecular breeding with the objective of increasing pyrethrin content has been slow for lack of a suitable gene transfer system. Regeneration recalcitrance is a crucial barrier to establishing a genetic transformation system in pyrethrum. Therefore, in this study, an Agrobacterium-mediated transformation system in pyrethrum was developed using shoot apical meristems from germinated seedlings. Factors affecting tran

Purpose: A favorable environment is available for the cultivation of Pyrethrum in the hilly regions of India, as well as in some mountainous areas of India. In view of the demand for Pyrethrin, it is very necessary to promote the huge cultivation of Pyrethrum. There is no misconception that research work has not been done to promote Pyrethrum, but the data related to the assessment of the right amount of nutrients required for the crop is not available in research related to agrotechnology. If the crop is to be taken as a ratoon crop, then it is very important to estimate the amount of nutrien

Abstract:

Anacyclus pyrethrum (L.) Lag has a long tradition of medical use in Algeria. We report for the first time the antioxidant, functional and neuroprotective properties of this plant from Algeria. Differences in biochemical and physiological properties for the aqueous and methanol extracts of A. pyrethrum are reported and related to the main chemical constituents. The A. pyrethrum extracts contained amino acids, caffeoylquinic acids, N-feruloyltyramine and alkaloids, including including N-alkylamides, common in this plant species. Aqueous extracts (0.1 mg/ml) are neuroprotective against H2O2-induc

Abstract Pyrethrum (Tanacetum cinerariifolium (Trevir.) Sch. Bip.) is an autochthonous insecticidal plant from Dalmatia (Croatia). It is commercially grown worldwide with a particularly fast expansion in Africa and Australia (Tasmania) and used as a natural insecticide. The study was conducted in Istria, Croatia, in a greenhouse, to determine the effect of soil type on the germination of pyrethrum seeds. The effect of different soil types on the germination of pyrethrum was found to be highly significant. The highest percentage of germination was found on white clay loam (soil type 2), and the

Pyrethrum (Tanacetum cineraiifolium) which is a natural insecticide has many properties, but the most important are raid action, very low toxicity for mammalian, lack of insect immunity, broad of activity, lack of persistence and degraded quickly by UV in sunlight and very effective insect repellent. Organic farmers can use pyrethrins as an insecticide for fruit and vegetable crops. Easily degraded by oxygen, light and temperature, pyrethrum compounds are environmentally friendly and compatible with organic farming.

Due to the high repeatability and large genome (1C-value = 9.58 pg) our previous attempts to develop microsatellite markers using the traditional method were unsuccessful. Now we have used Illumina paired-end whole genome sequencing and developed a specific procedure to obtain useful microsatellite markers.

When the donor tissues of tansy were cultured under high light intensity the leaves contained anthocyanin and became brown during enzyme maceration. In contrast, donor tissues cultured under low light intensity produced leaves without anthocyanin. Depending on t

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