How do farmers use seedling nets or covers to protect seedlings from pests and diseases?

Farmers use seedling nets or covers to create a physical barrier around young plants, protecting them from pests and diseases. These covers can be made of various materials, including lightweight fabrics or fine mesh, which allow light and air to reach the seedlings while keeping out larger pests. They prevent direct contact between seedlings and harmful insects, reducing the risk of damage and disease transmission. Additionally, these covers can help maintain a more consistent microclimate around the plants, which can reduce the growth of fungal diseases that thrive in damp conditions. By using seedling nets or covers, farmers can reduce the need for chemical pesticides, promoting more sustainable and environmentally friendly agricultural practices.
