Crop Heat Units (CHU) are based on a principle similar to GDD. CHU accumulations are calculated on a daily basis, using the maximum and minimum temperatures, however, the equation that is used is quite different. The CHU model uses separate calculations for maximum and minimum temperatures. The maximum or daytime relationship uses 10°C as the […]
Growing Degree Days Growing degree days (GDD), an estimate of accumulated heat, are used to predict the growth and development of plants, insects and diseases during the growing season. Insect, disease and plant development are very dependent on temperature and the daily accumulation of heat. The amount of heat required to advance a plant or […]

When scouting for insects that move too quickly in the canopy to be spotted or counted, or insects which are difficult to detect, it may be beneficial to use a drop cloth, insect traps or a sweep net to collect and count them. Using a Drop Cloth Spread a white drop cloth on the ground […]
Field scouting is an important part of cropping system and farm management. Ongoing monitoring of fields and crops throughout the growing season and beyond, allows a producer to identify issues and apply remediation in a timely manner to minimize negative economic impact, while improving field operation efficiencies. Some problems cannot be addressed when observed, but […]
Tools used to monitor crop development and pests vary with the crop and the pest. Basic field scouting equipment includes: Professional scouts often carry other tools that could include: When scouting, proper clothing is important for protection from the sun and from other unknown risks such as poisonous plants, ticks and mosquitoes. Be aware of […]
