Which of the following statements is true regarding non-fumigant nematicides?

The statement that non-fumigant nematicides are typically applied preventively is accurate because these products are designed to create a protective barrier in the soil that targets nematodes before they become a problem. Applying them preventively helps to manage nematode populations by hindering their establishment and reducing potential crop damage.

Non-fumigant nematicides are generally used in conjunction with integrated pest management strategies and are applied during the early stages of crop development or prior to planting to safeguard plants as they grow. This proactive approach is essential for effective nematode control, as it allows for the suppression of populations before they can adversely affect crop health and yields.

This reason distinguishes preventive application from other options, which imply limitations or conditions under which nematicides operate that do not accurately reflect their usage.
