What is a typical symptom of Phytophthora in young soybean seedlings?

A typical symptom of Phytophthora in young soybean seedlings is off-color yellowing and wilting. Phytophthora is a water mold that affects plants primarily in saturated soil conditions, leading to root and lower stem rot. When seedlings are infected, they often display a yellowing of the leaves, which is indicative of nutrient deficiency and stress caused by the pathogen disrupting normal water and nutrient uptake.

The wilting occurs because the roots are compromised, making it difficult for the plant to absorb water adequately. As a result, affected seedlings may not thrive, and the visible symptoms can serve as early warning signs for growers to take preventive measures to mitigate further damage. Recognizing these symptoms is crucial for effective management and control strategies against this pathogen to protect young soybean crops.
