Pest Control Adviser (PCA) Plant Pathogens Practice Exam

Not adhering to treatment thresholds for pathogens can lead to economic losses due to crop damage or yield reduction. When treatment thresholds are ignored, it can result in uncontrolled pathogen populations that can severely impact plant health and productivity. Pathogens, such as fungi, bacteria, and viruses, can cause disease outbreaks that affect crop growth, resulting in lower yields and possibly reduced quality of harvested produce.

As crops become more affected, this can lead to increased costs associated with managing the outbreak after it has occurred, which can include expenses related to additional treatments, labor, and loss of revenue from unsellable crops. The economic implications extend beyond immediate yield loss; they can affect market prices, farm profitability, and overall agricultural sustainability in the long term. Recognizing and adhering to treatment thresholds is essential for maintaining healthy crops and minimizing economic risk in agricultural practices.
