Fish attractant: Along the Coramandal coast, fishermen throw neem branches in the sea, fishes get attracted to them in large number during their spawning or egg laying period and can then be caught easily.
Green manure: Leaves, young branches and the oil cake (which is the best) constitute good green manure. This is a common practice in South India. Leaves are rich in potash and phosphorous and is a well tried and excellent manure.
Insect repellent: New and fresh leaves are dried and these act as good insect repellents. They are used in many libraries to prevent book worm attack for old books and records. Woolen cloth as well as hand loom dresses are also well protected by this means. Rice and other food grains are also stored along with such dried neem leaves to keep them insect free. The smell of the leaf is very upleasant and fatal to many insects.
The smoke from small branches along with green leaves placed on live coal is a good disinfectant for a closed room; by this way the bees are driven out from their hives. To keep young coca plants and other valuable trees in nursery, an application of neem oil is done.
Dye making: The gum of neem is used in making pigments for clothes. This is used to dye silk yarn in Maharashtra, cotton cloth (along with neem oil) in Mysore and Coorg specially to give the deep yellow colour while the bark is used in Sindh to secure a red pigmentation.
