IPM has been around my whole life. 

Supervised control of field crop insect
pests was first developed on the northwest
side of the San Joaquin Valley.

A successful supervised control program
in a district requires the following:
an intimate knowledge of the insects; a
sufficient acreage to finance the district;
an informal grower cooperative to administer
the district and a properly
trained entomologist to supervise the insect
control.

Supervised Control of Insects
utilizes parasites and predators and makes
chemical control more efficient
