Will not harm fish, waterfowl, plants or mammals. To make pyrethrum spray, mix 1 tblsp freshly ground dried flowers with 2 qt. (2 litres) hot water. Add a little soap and let stand. *CERTIFIED* This is a high potency strain grown for the world pyrethrum market. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 50 seeds/pkt Questions and answers; 1. Where is the seeds from? I want to know the original grow conditions.  The seeds we sell are produced in the United States. The original stock for this breeding line came from the major pyrethrum producing countries Kenya, Tanzania, Ecuador and India about 20 years ago. This line is currently used for pyrethrins production.  > 2. What's the flower yield?  The dry flower yield is the most variable trait in pyrethrum. Growing conditions such as climate, soil type, nutrient status of the soil have profound effects on flower yields. Typical yields for this line range from about 400 to 800 kg/ha. Much higher flower yields -- up to about 2000 kg/ha -- are possible from improved cultivars.  What's the contant of the pesticide pyrethrin in the flowers?  The typical pyrethrins content in the dry flowers for this line ranges from about 1.4 to 1.8 per cent. But this line has shown some useful variability -- with some individual plants exceeding 2.0 percent -- so this line can easily be used as a basis for a breeding program to push the pyrethrin content higher. The elite varieties get up to 3.5 percent and beyond.     What is Pyrethrum? Pyrethrum is a botanical insecticide produced primarily in the flowers of Tanacetum cinerariaefolium, a species of the chrysanthemum plant family. Pyrethrum plants have historically been grown in commercial quantities in Kenya, Tanzania, Rwanda and Papua New Guinea. Over the past decade, Tasmania and Uganda began producing pyrethrum. Today Kenya and Tasmania are the largest pyrethrum growing and producing countries.In East Africa the mature pyrethrum flowers are picked by hand, sun dried to remove moisture, and sent to a processing plant for extraction of the active ingredient-pyrethrins, a mixture of six closely related esters. In Tasmania the flowers have been bred to synchronously flower so they can be mechanically harvested. As in Africa, the flowers are sun dried and processed to produce the insecticide pyrethrum.Pyrethrum is an ancient insecticide. The insecticide properties of the flowers were documented in the early 1800’s but it is suspected that the flowers were used to kill insects a considerable time earlier. The first commercially available products were powders made from ground flowers and later crude oil extractions became popular. Today, the refining of crude pyrethrum extract to remove the plant material, waxes, etc. is a highly complex process resulting in a product that is clear and free of allergens.Pyrethrum has been used effectively to control insects for decades and is non-persistent, decomposing rapidly in the environment. This rapid degradation of pyrethrum has resulted in little known cases of insect resistance making it an excellent choice for the control of agricultural pests.From a toxicological viewpoint, pyrethrum has been extensively studied. It is low in acute toxicity to man and other vertebrate animals, is non–carcinogenic, causes no adverse reproductive affects and is non-mutagenic. *********************************************** Notification: your packet of seeds contains organic product. This product therefore comes to you in completely natural form, without hormones or other chemical agents and contaminants intended to "enhance" what nature provides you. While we typically experience successful germination ranging from 40% to 80% of total seeds planted, no guarantee can be made as to the natural yield you will experience. Also, your seeds were packaged in a facility containing other seeds and organic plant matter. While great care has been taken to ensure that you receive the freshest, purest organic seeds possible, occasionally seed packets contain other organic matter not intended for packaging.   Thank you for your order, and we wish you the best of luck in your natural plant growing experience!
