GIS can be used in pesticide management in several ways: 1) GIS monitors and maps the spatial extent of pests and diseases to identify patterns and link locations to other spatial data. 2) GIS predicts the potential spread of pests and diseases and provides input for risk assessment models in pest control. 3) As shown in a case study, GIS was used to map the spread of a banana disease in Africa, identify priority intervention areas based on food security, and target control efforts to maximize impact.

2. Pest & Pesticide
Pest:
A pest is "a plant or animal detrimental to humans or human concerns
(as agriculture or livestock production)“; In its broadest sense, a pest is
a competitor of humanity.

3. Pesticide:
 Pesticides are substances meant for attracting, seducing and then
destroying any pest.
 They are a class of Biocide.
 The most common use of pesticides is as plant protection products (also
known as crop protection products), which in general protect plants
from damaging influences such as weeds, fungi, or insects.

4. Role of GIS in Pest & Pesticide Management:
 Geographic information systems (GIS) provide valuable tools in
monitoring, predicting, managing and fighting the spread of pests and
diseases.
 The tools offer opportunities for cost-effective and efficient targeting
of control interventions.
 In monitoring, GIS can be used to determine the spatial extent of a
disease, to identify spatial patterns of the disease and to link the
disease to auxiliary spatial data.
 GIS can also be used to predict the projected spread of diseases, to
provide input for risk assessment models in pest control and in
quantifying changing thresholds of pests and diseases due to climate
change.

5. The potential benefits of GIS techniques in disease and pest control: A
Case Study Based on a regional project in central Africa
 Pests and diseases of bananas threaten the livelihoods of over 20
million people in the Great Lakes region.
 This case study illustrates the use of GIS tools on data collected to
identify critical intervention areas to combat the spread of
Banana Xanthomonas wilt (BXW).
 In a survey covering the Great Lakes region, on-farm incidence of the
disease was monitored and precise GPS coordinates of each sampled field
were recorded.
 This enabled accurate mapping of the disease and performing the various
spatial analyses, permitting an understanding of the geographical
distribution of BXW infection.

6.  Data on food security and dependency on banana to rural populations
was linked to the BXW severity to target priority areas of interventions
and maximize impact.
