What could be an early symptom of nematode damage in corn?

The early symptoms of nematode damage in corn often include stunting and off-color leaves. Nematodes, particularly those that are harmful to corn, can cause root damage, which affects the plant's ability to take up nutrients and water effectively. As a result, the plants may exhibit reduced growth, which is characterized by stunted height compared to healthy plants. The off-color leaves can indicate nutrient deficiencies or stress as the plant struggles to maintain its normal physiological functions due to impaired root systems. This response is particularly characteristic of nematode infestations, making it an important symptom for growers to recognize for early intervention and management. Other options suggest symptoms that are either not typical of nematode damage or indicative of healthy plant conditions.
