The second International Neem Conference was held in West Germany in December 1983. Over one hundred delegates participated in this conference. The neem tree came into sharp focus in the context of the adverse effects of man-made chemical insecticides. It is a principal source of inexpensive natural repellent and causes no environmental damage.
A noted animal physiologist, Dr. L.M. Schoon Hoven, of an agricultural university at Wagenigen in Holland, said that the unique defence system in neem provided a rare opportunity for insect control. Experiments held in Togo, Africa, had showed that neem leaves worked into the soil, reduced the population of the plant parasitic nematodes and promoted “spectacular increase” in crop yield.
Now the question arises, what exactly enabled the neem tree to survive, perhaps for millions of years, in a world of greedy insects? And what enabled it to provide protection to the rest of the biological world?
The reason given at the International Neem Conference was that the tree has developed, over the ages, a strong and steady chemical defence system, which enabled it to thwart the heavy pressure exerted by insects.
Only an All-Knowing and All-Powerful Being could have invested a Neem plant with such magic and farseeing properties.
