Pyrethrum seeds

Pyrethrum plant

Pyrethrum Himalaya is economically important as a natural source of insecticide. The flowers are pulverized and the active components called pyrethrins, contained in the seed cases, are extracted. Pyrethrins attack the nervous systems of all insects, and inhibit female mosquitoes from biting. When not present in amounts fatal to insects, they still appear to have an insect repellent effect. They are harmful to fish, but are far less toxic to mammals and birds than many synthetic insecticides and are non-persistent, being biodegradable and also breaking down easily on exposure to light.

Common Name : Pyrethrum
Botanical Name : Pyrethrum (Tanacetum cinerarifolilum 

Syn., Pyrethrum cinerarifolium, Chrysanthemum cinerarifolium )
 

Plant : The plants bear numerous flower heads which measures 6-9 mm when closed, and 9-12 mm, when open. The involucres consist of 2-3 mm of yellowish or greenish yellow, lanceolate hair bratcs. Each flower head bears a receptacle 4-8 mm in diameter
 

Soil and Climate : Fertile and well–drained soil is the best for growing pyrethrum successfully.
         
Cultivation : Pyrethrum is generally propagated by seed as well as the crop can also be raised vegetative by splits. It is successfully grown in plains through seedling prepared by seed in nursery.
 

Seed rate : Seed 500 gram of seed should be shown in about 50 square meter land for growing nursery for one hectare of land (About 50,000 seedlings).
 

Preparation of fields : For field preparation one two ploughing with mould board plough followed by 2-3 harrowing and planking are required to get a fine tilth.
 

Preparation of Nursery : Two to three harrowing are enough for preparation of seed beds.
 

Manures and fertilizers : Crop responds well to increase level of 60 kg/h Phosphorus.
 

Intercultural : Pyrethrum crop requires weed free condition particularly in the initial stage of establishments.
 

Irrigation : Pyrethrum require irrigation every fortnight from planting to harvesting.
 

Harvesting and drying : Three harvests of flower are obtained as the following continues for 9 months. The crops give poor yield during the first yeas and the optimum yields are obtained only during 2nd and 3rd year.
 

Yield of flower and pyrethrins content : 225-250 kg/ha/year Flower yield and pyrethrins contents in flower depends on agro-climatic condition and cultural practices.

Pyrethrum seeds for sale

Pyrethrum-Chrysanthemum cinerarifolium
Aromatic perennial, leaves dissected into liner segments. Flowers white, 2-5cm.across.Pyrethrum refers to several Old World plants of the genus Chrysanthemum (e.g., C. coccineum) which are cultivated as ornamentals for their showy flower heads. Pyrethrum is also the name of a natural insecticide made from the dried flower heads of Chrysanthemum cinerariifolium and Chrysanthemum coccineum.

Other uses of the herb: The dried flower heads are used as an insecticide, they are a source of the commercially available insecticide "pyrethrum", which is non-toxic to mammals. This species is less effective than T. cinerariifolium. Only the yellow disk rays contain pyrethrins. Once dried, the flowers or the powder retain their insecticidal properties almost indefinitely.

Propagation of Pyrethrum: Seed - sow spring in a greenhouse. Only just cover the seed and do not allow the pot to dry out. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring.
