What are some natural insecticides?

Regardless of the desire and the well -intentioned effort of many organic gardeners, it is time to have insecticides to be used to eliminate errors that infest and destroy garden crops. Many of them prefer the use of natural insecticide rather than synthetically produced chemical insecticide. Rotenone and pyrethrum are well known and widely used natural insecticides derived from plants. Other natural insecticides include nicotine, Neem and soap. Rotenone is derived from the root of tropical and subtropical plants of the genus derris . Rotenone acts as a broad -spectrum natural insecticide, which is firs both in contact and ingestion. Rotenone is usually used as a dust or spray, and although it is not toxic to plants, it is highly toxic to fish and slightly toxic to heat mammals.

Pyrethrum is derived from the Dalmatian chrysanth and is used in the form of dust or liquid suspension. In the laconcentration of RGE, it acts as a natural insecticide by attacking the central nervous systeminsects. Pyrethrum in small concentrations may not be toxic to insects, but retains the ability to bounce insects. Pyrethrum is toxic to fish, but less toxic to mammals than synthetic pesticides. It is biodegradable and easily disintegrates with exposure to light.

Some organic gardeners recommend using soap that has been used as a natural insecticide for hundreds of years. The dilution of liquid washing machines, such as ivory, with water per 1-2% solution that can be sprayed to cover the plants, was found effective in insect control. However, the alerts change because repeated and thorough coverage with a high concentration of soap can cause damage to certain plant species. Soap as a natural insecticide can be much less toxic to humans and animals than other alternatives, but it can also be much less ep.efective, especially in the treatment of infestation.

While it was found that nicotine, neem and nextBotanical insecticides that are not discussed here are effective with minimal to mild success, any kind of natural insecticide should be used as little as possible. The fact that you use natural insecticide rather than synthetic does not mean that it is less harmful to animals or humans. The application of any type of natural insecticide should be carried out safely and only at the frequency necessary to maintain a healthy crop or vegetable.
