Crop scouting
Crop scouting is the process of precisely assessing pest pressure (typically insects) and crop performance to evaluate economic risk from pest infestations and disease, as well as to determine the potential effectiveness of pest and disease control interventions. Scouting is usually sold as a commercial service to farmers as part of Integrated pest management. New tools are available to increase the effectiveness of crop scouting, including specialized field instruments and handheld computers with GPS, enabling geo-tagging of crop problems. There exists a new generation of crop scouting systems that enables growers and crop consultants to precisely and accurately locate and tag crop issues, visualize them on an aerial map and make decisions for site-specific treatments.
==Preparation==
Before starting any actual scouting, preparation is essential to provide accurate information in an efficient manner. Crop scouting is a Integrated pest management strategy that looks at many different aspects of crop production, not just any single pest or problem.〔 Scouts must be actively observing environmental conditions, beneficial insects, pest insects, diseases, weeds, crop growth stage, and the general health of the crop in question to get a complete picture of any problems.〔 Since field and landscape characteristics affect pest distribution, symptom expression, crop injury, and crop recovery, it is important to develop a complete field history in order to properly assess and plan management strategies.〔
