What is a primary use of systemic fungicides in seed treatment?

The primary use of systemic fungicides in seed treatment is to treat seedborne diseases. Systemic fungicides are designed to be absorbed by the seeds and subsequently translocated throughout the plant as it grows. This property allows them to combat various types of fungal pathogens that can infect seeds and establish themselves in seedlings. By treating seeds with systemic fungicides, growers can significantly reduce the risk of diseases that can damage or destroy young plants, which is crucial for achieving healthy crop establishment.

This method is particularly important in agricultural practices, as seedborne diseases can lead to reduced yields and quality of crops if not managed effectively. The proactive application of systemic fungicides ensures that the plants are protected right from the germination stage, improving the likelihood of successful growth and development. This contrasts with other options which are not the main purpose of systemic fungicides in the context of seed treatment.
