Why is it important to use insecticides on seeds?

Using insecticides on seeds is crucial primarily because they protect against pest invasion during the planting phase. Seeds are vulnerable to a variety of pests that can damage them before they even have the chance to germinate and grow into healthy plants. By applying insecticides directly to the seeds, farmers and growers can create a protective barrier that reduces the risk of infestation by insects that might consume or damage the seeds, thereby ensuring a higher rate of successful germination and healthier plant development.

This proactive approach is vital in agriculture since pests can significantly impact crop yield and overall productivity. While other options, such as improving soil nutrients or providing health benefits to plants, contribute to plant growth, they do not directly address the immediate threat of pest damage during the early stages of seed development. Similarly, enhancing seed color does not have any direct relationship to the protection of the seed. Instead, the primary focus of using insecticides on seeds is to ensure that they remain intact and free from pest-related threats at the critical time of planting.
