What is a common issue controlled by Metalaxyl and Mefenoxam?

• A. Weed growth
• B. Plant nutrient deficiencies
• C. Seed rot and damping off
• D. Insect infestations

Answer: (C)

Metalaxyl and Mefenoxam are both systemic fungicides primarily used to control certain fungal diseases in plants. Their effectiveness is particularly noted in managing diseases such as seed rot and damping off, which are caused by various fungi, including species of *Pythium* and *Phytophthora*. These diseases often occur in the early stages of plant development, leading to significant losses in seed germination and plant establishment if not effectively managed. By targeting these pathogens, Metalaxyl and Mefenoxam help ensure that seeds can germinate properly and develop into healthy seedlings, ultimately contributing to improved crop yields. The focus of these chemicals on fungal pathogens is crucial, as addressing issues like weed growth, nutrient deficiencies, and insect infestations requires different strategies and treatments.
