Clark Aitken, a crop specialist formerly with AGRIS Co-operative, inspects soybean leaves for aphids north of Chatham.
I can remember when I was a kid being a Cub and Boy Scout member at our troop at Victoria Avenue United Church. The motto for the Boy Scouts was ‘Be Prepared.’ That’s always a good plan in all areas of life, including the agriculture sector.
As our producers grow more crops, the pests and diseases that attack these crops also become more challenging. Insects and disease can have a devastating effect on crops and on the producer’s bottom line. That’s why our producers walk their fields a number of times during the growing season and check for the presence of insects and diseases.
This area of insect and disease detection is so specialized, many producers are turning to ‘crop scouts’ to help them detect these pests and make recommendations on how to deal with the problem in their fields. Crop scouts are trained professionals, most having a degree in agriculture and specialized training in crop management practices, especially as it relates to insects and diseases.
Crop scouting is one tool used as part of an Integrated Pest Management (IPM) strategy that can help farmers make important and timely decisions in their crops. Crop scouts assist farmers who may not have the time to spend inspecting their crops for pest and disease pressures.
Crop scouts are able to examine any of the crops grown in Chatham-Kent. A crop scout is also a second pair of eyes for the farmer as a check to ensure they both see the same things in the field. A crop scout provides reassurance and also begins a record keeping system of what is going on in the fields, so the farmer can concentrate on other aspects of their business operations.
Scouting also provides timing accuracy for crop spraying. Knowing the insect and disease thresholds is an integral part of the process. A threshold is the level of plant damage or the number of insects at which treatment is recommended – hopefully the point at which the benefits of control will outweigh the costs of control. If spray is applied too early, then the chemical application is wasted. If the spray is applied too late, the crop damage is already done.
A crop scout may visit a producer’s field one to two times a week depending on a number of factors. They monitor for insect, disease, weed pressures, nutrient deficiencies, physiological problems, overall crop health, and also take tissue and soil samples. The specialty crop scouting reports are GPS (Global Positioning System) mapped and recorded so when an issue is identified, they can return to the same area a few days later to re-evaluate the problem or return in the fall to take soil samples if needed.
Another set of eyes for scouting agricultural fields is the use of drones, which are unmanned aerial vehicles (UAV). The drone will fly over a field on a pre-determined flight path and then record and transmit high-quality aerial images of the field. This becomes another effective scouting tool in identifying any issues within the farmer’s field.
Our agricultural sector will continue to expand into more specialized and diverse areas. Our farmers need to ‘be prepared.’ Crop scouting will play an even more vital role in the business of agriculture.
