RT Journal Article SR Electronic T1 Landscape Integrated Pest Management JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 253 OP 259 DO 10.48044/jauf.1990.057 VO 16 IS 10 A1 David G. Nielsen YR 1990 UL http://auf.isa-arbor.com/content/16/10/253.abstract AB Discussions of Integrated Pest Management (IPM) are commonly introduced by the speaker or writer proclaiming that there are probably as many definitions as there are those who consider the subject. The time for that mind-set has passed. There has been enough said about IPM during the past 30 years in enough circles and forums that most of us understand the concept and its intent. For the purposes of clarity, I’ll define IPM as a common sense approach, using environmentally conservative methods to maintain pests below defined economic or aesthetic damage levels. Targeted intervention tactics are used, based on monitoring plant vitality and abundance of pests and their natural enemies. In short, IPM is an informed decision-making process that resuits in efficient risk reduction.
