Neem Oil

Neem oil is extracted from the neem tree, Azadirachta indica Juss., a member of the Meliaceae family that originates from the Indian subcontinent and is now valued worldwide as an important source of phytochemicals for use in human health and pest control. Azadirachta is a fast-growing small-to-medium sized evergreen tree, with wide and spreading branches. It can tolerate high temperatures as well as poor or degraded soil. The young leaves are reddish to purple, while the mature leaves are bright green, consisting of petiole, lamina, and the base that attaches the leaf to the stem and may bear two small lateral leaf-like structures known as stipules (Norten and Pütz, 1999Forim et al., 2014).

Neem oil contains at least 100 biologically active compounds. Among them, the major constituents are triterpenes known as limonoids, the most important being azadirachtin, which appears to cause 90% of the effect on most pests.

The oil is considered a contact insecticide, presenting systemic and translaminar activity (Cox, 2002). It has a broad spectrum of action, inhibiting feeding, affecting hormone function in juvenile stages, reducing ecdysone, deregulating growth, altering development and reproduction, suppressing fertility, sterilizing, repelling oviposition, and disrupting molting processes (Brahmachari, 2004). Little is known about the mode of action of azadirachtin as a feeding inhibitor, although it is possible that it stimulates cells involved in feeding inhibition, causing weakness and pest death (Brahmachari, 2004).

Neem oil is particularly effective against small soft-bodied insects. Examples include aphids, thrips, spider mites, mealybugs, scale, and white flies. When applied directly, the oil can coat their bodies and kill them – or otherwise interfere with reproduction and feeding. It is also said to repel mosquitoes, flies, cabbage white butterflies, and moths.

On the other hand, neem oil is not toxic to bees when used correctly! It also doesn’t bother other beneficial insects like ladybugs, earthworms, parasitic wasps, spiders, or adult butterflies – as long as they aren’t directly sprayed with it! Therefore, take care to spray it only in the evening hours, when beneficial insects are least active. Note that neem doesn’t do much to control caterpillars, except maybe repel their adult butterfly or moth form.
