Pest and pest injury identification

Pest and pest injury identification

An injury caused by pests is defined as any observable deviation from the normal (healthy) crop. Injury may lead to damage/crop loss, i.e any detectable decrease in quantity and/or quality of a crop output. Damages can lead to economic losses (but the relationship between damage and economic loss is not systematic). A yield loss, the most commonly studied sort of crop loss, is defined as a quantitative direct crop loss.

In this section of QuantiPest, we focus on identification of pests and pest injuries, observable in the field. Since weed identification is less specific than pest and disease identification, this part of the platform contains one entry listing the main pests and diseases per crop and one entry dealing with weed identification, independently of the considered crop.
