In most field situations, this means observing and sampling at several sites and recording the data. This field record usually includes a map showing site location and sampling results. The grower now has a record of pest and natural enemy conditions at a particular point in time, a snapshot, which can be compared to previous and subsequent data. This forms the basis for pest management decisions. Careful observation of diseases, insect pests, and predators is what IPM is all about.
Regular monitoring allows for more efficient use of pesticides.
Less trips are made through the orchard and with improved timing of application, pesticide expense is lowered. Fewer sprays also helps preserve natural enemies. IPM means having a working knowledge of the biology within your orchard. It is no secret that fewer pesticides are available every year. One reason for this is that it has become expensive to research, develop, license, and market new pesticides, particularly for minor crops that represent a limited market.
