CONCLUSION
The integrated pest nmanagemcnt strategics presented here have been
developed using a combination of large experirnental ficld plots and farmers'
fields, as well as testing through field technicians. All components of the
system, cven if used individually, can result iii substantial savings on chemical
sprays. Initial results f'ron on -larmi rescarch indicate that fa rmners appreciate the
di fferent colnponents to varying degrees. Ilowever, all were able to understand
how to implement the various technologies. An economic appraisal is currently
being undertaken and will be reported elsewhere.
Nevertheless, this approach has barely left the developmental stage. Much
more eflort is needed to create an awarcne:;s of its advantages and uses among
tanrers themselves before a judgcenien can be made as to how well it can be
inplemented and how well it suits tie needs of the Filipino cotton Iarmer.

Although not mentioned as authors, many have ::ontributed to the work
presented here. Foremost of these are the research assistants and field technicians
ol the Phililppine-Gernan Cotton Project who did all the hard work. Above all,
however, Mr. Mauricio Disu and his staff, who through their tireless efforts
during countless lectures and field trainings, have created the necessary
tuderstanding of IPM among I'arnrcrs and PhilCotton production personnel.
Only in this environment could positive results be achieved.
