What happens to seedlings with post-emergence seedling blight?

Seedlings affected by post-emergence seedling blight typically exhibit symptoms such as yellowing, wilting, and dying. This condition occurs when fungal pathogens or other stressors attack the seedlings after they have emerged from the soil. The blight can disrupt the plant’s normal physiological processes, leading to nutrient deficiency and water uptake issues, which manifest as wilting and chlorosis (yellowing of the leaves).

In contrast, the other outcomes presented in the choices do not accurately represent the impact of post-emergence seedling blight. The development of green lesions would suggest a different type of plant stress or disease, while normal growth or early maturation would indicate that the seedlings are healthy, which is not the case during a seedling blight scenario. Thus, option B accurately reflects the detrimental effects that post-emergence seedling blight has on young plants.
