Neem has been found highly compatible with nuclear polyhedrosis virus as lethal
time log has been found to considerably reduced when used in combination with
NPV against Spodoptera litura. Similar compatibility has been noticed with Bacillus
thuringiensis and one of the neem extracts even synergised the effect when used
against Plutella xylostella on cabbage. Ozoneem, a commercial neem formulation,
plus Cypermethrin offered far better control of cotton bollworms than either used
alone. Low damage of pods and higher yield were recorded when aqueous extract of
seed kernel was alternated with either fenvalerate or Cypermethrin for the
management of Helicoverpa armigera in Pigeonpea. Problems such as variations in
sensitivity of insects, doses, timing of application, stability etc. in the utilization of
neem products would be discussed in details.

Neem seed kernel has about 55 biologically active compounds. No study has been
done on the identification of gene responsible for production of these compound and
their consequent transfer in other plants. Azadirachtin is the most important
biologically active compound and its quantity varies greatly in neem trees so is the
case with oil and other compounds. A survey must be conducted immediately to
identify elite trees with different objectives for development of new varieties for future
propagation.

India is proud owner of about 20
million trees. Neem is cheap,
safe, effective, available and
renewable source of natural
pesticides and fits-in-well in
sustainable agriculture as well
as the life style of Indian farmers.
With little efforts farmer can easily
be trained how to grow (does not
compete with crop) and use
neem for solving their pest
problems. Government must take
immediate steps to popularize
use of neem as alternative to
hazardous synthetic insecticides.
