What is Neem Pesticide?
Neem is a tree Azadirachta indica, from which people get a natural Neem pesticide and medicinal oil. Neem pesticide controls successfully numerous farm and home pests. Usually, Neem pesticide does not destroy the pests immediately, but repels and exhausts the pests, leaving people, animals, and crop untouched. Neem insecticide disturbs hormonal balance of the insects and they expire before they molt. Neem oil is produced from the seeds of the neem trees. Neem oil is not only attractive natural insecticide, but is as well used in cosmetics and medicine.
Benefits of Neem pesticide
Neem pesticide may become the ideal insecticide because it attacks numerous dangerous species and leaves people, animals, and beneficial insects intact. Neem insecticide is decomposed naturally and does not provoke the development of genetic pest resistance.
Ingredients and mechanisms of action of Neem pesticide
Neem products contain a number of active ingredients with various mechanisms of action. These substances defer from the chemicals in the synthetic pesticides. From the biochemical standpoint the neem compounds bear resemblance to steroids. Neem pesticides include only carbon, hydrogen, and oxygen. Neem pesticides do not include the atoms of chlorine, phosphorus, sulfur, or nitrogen characteristic for chemical pesticides. Neem pesticides do not kill directly, but modify the behavior and metabolism of insects. The insects lose the ability to feed, breed, or undergo metamorphoses, and therefore are unable to cause any harm. Azadirachtin, entering into the composition of Neem insecticide, interrupts insects’ metamorphosis and is at the same time distasteful for pests. Azadirachtin interferes with feeding, molting, mating, and egg blowing. Salannin of Neem pesticide is a potent repellent.
Protective action of Neem pesticide
The pesticidal mixtures of active compounds are amazingly efficient. The probability of the development of genetic resistance to Neem insecticide compounds is very low because they all work in different ways and on different stages of insect life cycles. Moreover, some components may act as systemic pesticides being absorbed and transported all over the plants. Therefore, Neem insecticide extracts can be sprinkled on the soil. The active ingredients are absorbed by the roots and impregnate the plant defending it from within. This way of protection is good for wheat, barley, rice, tomatoes, and cotton.
Pest toxicity of Neem insecticide
Neem insecticide can suppress more than 200 species of insects, mites, nematodes, fungi, bacteria, and viruses. This natural pesticide kills pests after their eating the sprayed leaves. Other pests are repelled by the strong smell. Neem pesticide successfully controls aphids, whitefly, Japanese beetles, spider mites, and moth larvae. Sprays of Neem pesticide are also good against mildew, rust, scab, black spot, botrytis, anthracnose, leaf spot, and blight.
