What is Natural Pesticide or Insecticide?

Many plants have a natural protective mechanism which aids them in resisting and driving of pests. Some plant species produce substances which repel or poison the insect. The Neem Tree contains such substances which can be easily extracted and turned into a natural insecticide. Crushed seeds or seed kernels are mixed with water and the resulting solution used to treat the plants.

The Natural Pesticides or Organic Pesticides described here is a combination of natural substances made from plants or botanical sources. These Natural Pesticides are used to ward off certain animals and insects, and to kill certain insects. Oils or chemicals inside these oils are registered as pesticide active ingredients. Botanical Pesticides commonly known as natural pesticides or organic pesticides are derived from plants those known for their insecticide or pesticide properties. All the pesticides derived from plants are not safe for humans, pets, and fishes. Some Natural Pesticides are found to be toxic for Humans and other mammals. Few natural pesticides are toxic to humans and nontargeted pest and insect too, therefore you should always read the label before using any organic pesticide.

Some of the botanical extracts are pyrethrums, nicotine, and rotenone, though these are powerful natural pesticides their safety towards humans and other mammals are not established. Whereas Neem Oil is an established Safe yet Effective Natural Pesticide.

Pesticides: Natural Products

When a pest or disease is devastating your plants, refrain from grabbing the strongest chemical you can find. Always try simple and safe controls before using any pesticide. For example, sometimes a strong blast of water from a hose is all it takes to get rid of a pest. You can also hand-pick pests like caterpillars and drop them into soapy water. Or shake Japanese and potato beetles off plants onto a sheet. And aphids, cabbage worms, and whiteflies are attracted to yellow so they can be trapped by covering a piece of yellow poster board with sticky glue and hanging it among the infested plants.

If physical controls don’t work, the next thing to try is a homemade organic pesticide. Homemade preparations are generally milder than commercial pesticides. For example, garlic makes an effective spray for most insects. Simply puree 15 garlic cloves and one pint of water in a blender, strain the mixture through a cheesecloth into a clean spray bottle, and apply to the tops and bottoms of all leaves. Repeat every few days until the problem is gone.

If homemade sprays are not strong enough, you may need to buy an organic pesticide. Horticultural oils, insecticidal soaps, and botanical insecticides are all organic pesticides. Most are safe to use on food Crops because they break down quickly and have no long-lasting effect on the environment. Nonetheless, they should be used as a last resort. Because they’re not only toxic to the pests and diseases you are trying to eradicate, they can also be toxic to insects, birds and soil microorganisms that are part of a healthy garden.

Before applying anything to your garden, identify the pest and disease you want to control so you can choose the most effective product. And always read the label and follow directions exactly.

Neem oil:

Neem oil is extracted from the tropical neem tree, Azadirachta indica. Neem Oil is a perfect Organic pesticide, composed of a complex mixture of biologically active compounds. More than 50 active ingredients in Neem Oil act as repellents, feeding inhibitors, egg-laying deterrents, growth retardants, sterilants, and direct toxins. Neem Pesticide act by contact and systemic action in plants. It’s active ingredients bio-degrade rapidly in sunlight and within a few weeks in the soil. Neem oil is established as non-toxic to humans and mammals. Clarified hydrophobic extracts of neem oil are also used in the treatment of fungal diseases of plants. Overall best natural pest control.

Natural Pesticides?

A number of Natural pesticides have been in use for many years, and have thereby escaped the cost of rigorous testing and licensing that operator today in the major agriculture countries of the world. Some of these are pyrethrum, rotenone or derris, nicotine sulfate, and ryania. Note that all consist of a number of compounds, which together act against the creation of resistance in pests. The insect toxicity of ryania is very selective. Nicotine is a very toxic substance to humane, 70 times more toxic then potassium cyanide.but is very valuable in specialized used, and production is increasing. Because it is very volatile, residues present no problem. rotenone is licensed for organic production. There was a recent scare about is possibly being linked to Parkson’s disease (a condition of tremor and paralysis in older people), but that condition was induced in laboratory rats only by injection.

It is interesting to compare pyrethrum, a natural product, first recognized in China, and long on the market, with azadires. Kenya and nearby parts of East Africa are the biggest producers of pyrethrum (70%of world production) but production there has been badly affected by a recent drought. Production is projected to increase, rainfall permitting. the Australian government and industry have invested heavily ($25 million estimated) into the development of a pyrethrum industry and the state of Tasmania now have 30% of the world market, with mechanized planting and harvesting in 2005 a  great of $700,00 was made for research on pyrethrum storage. Nowhere has received such support and focused research. In those states of the USA formerly dependent on the tobacco crop, pyrethrum has been considered as an alternative. Cost of labor used to rule it uneconomic, but new cultivars of Chrysanthemum with high pyrethrum content and mechanical harvesters now make it a possible crop. World demand is said to be four times greater than current production.

Why use Natural Pesticides?

An insect can inflict great damage to crops. Many Gardeners, therefore, use synthetic pesticides in order to drive away, or to control these pests: However, many of these synthetic pesticides are also highly poisonous for humans and livestock. Moreover, these substances destroy a great number of useful insects which are an important factor in natural control of pests. As a result, the plant is left unprotected against pests and increased spraying of pesticides is thus necessary.

These disadvantages can be avoided by using biological pesticides such as extracts from neem tree which are both effective in controlling pests and, at the same time harmless to humans and Other warm-blooded organisms.

Using synthetic pesticides are hazardous under any circumstances.

Along with targeted insects and pests, chemical or synthetic pesticides kill useful organisms also, especially predators, which in turns affect species and agricultural growth. Immunization of pests and Insects results in increased dosages and application of further toxic pesticides.

Synthetic pesticides use may result in the hazardous effects in animals, creating a potentially toxic environment for humans.
