How Pyrethrum is grown
Pyrethrum arises spontaneously but it is possible to cultivate it not only if you want to use it as an insecticide or repellent plant but also if you want to use it for decorative purposes since the plant is very ornamental and similar to the daisy. However the Pyrethrum needs a very fertile soil and needs to be placed in a sunny area and if this is not possible, it will be cultivated in a greenhouse where it will surely not suffer from temperature changes. This technique is widely used in Kenya and Congo, which are the major exporters of Pyrethrum. The seedlings must be purchased directly in the nurseries and then planted in the earth or in terracotta pots on the balconies of the house. Although very ornamental, the Pyrethrum is cultivated above all because it is used as an insecticide for the organic agricultural market since its effective insecticidal power is neither harmful for men nor for warm-blooded animals, so it can easily be used also in gardens urban areas where pets are easily circulated.
How to use pyrethrum insecticide
Pyrethrum insecticide can be found in all those stores that sell products suitable for organic farming but can also be found on the web. This product can be used in any season of the year and has a rapid knocking down effect with a very low toxicity, in fact the fruits can be collected and consumed, just two days after the insecticide treatment. It is suitable not only for vegetable, fruit and floral crops but also for ornamental plants that present aphids, lepidoptera, sawfly and other various insects.
The product should be diluted in 10 liters of water based on the crop to be treated and the infestation of the parasites. Treatments must be carried out during the coolest hours of the day and the entire plant must be soaked in order to create an effective barrier against mites. The pyrethrum has the ability to instantly eliminate all insects but has the gift of not entering the sap and is active only where the drops arrive, which is why it is necessary to spray the plant to be treated very well in every point. After 2 or 3 days from spraying, the effect of pyrethrum begins to decay due to contact with sunlight. The only defect of this important natural insecticide, is that it is not selective and practically in its net, could also run into insects deemed non-harmful such as bees and ladybirds. To overcome this problem, when using the insecticide, it is good to focus its action, only on the areas where the aphids appear.
Pyrethrum is harmful to fish so it is advisable not to use it near natural or artificial lakes because it could infiltrate the water. Commercial products should be kept in dark and dry places and should not be used after 24 months from purchase.
The pyrethrum used on pets
When you own a pet, you are facing various responsibilities even when you use chemical insecticides to defend them from the attack of ticks or insects that could cause deterrence to nourishment or disorders such as stopping growth or even very serious and deadly diseases such as the Leishmainosis. It is therefore up to the owner of the animal to eliminate the parasites from the animal's hair so that it cannot be damaged. Pyrethrum insecticide, being a completely natural product, has no harmful effect on children who inevitably touch the pet or other domestic animals. For example, if a dog is living with a cat, one must be extremely careful about the use of chemical pesticides because it could even verify the cat's mortality. This is why it is advisable to use a natural pyrethrum insecticide rather than a chemical one. External drugs for use on pets are also available as shampoos or gels.
