In soil fumigation, the treated area may be replanted usually within how long?

• A. Immediately
• B. Within a month or less
• C. Several months later
• D. One year later

Answer: (B)

After soil fumigation, the pest control effect lasts only for a limited window as the fumigant dissipates through the soil. To protect young plants from potential phytotoxicity and to ensure the crop is established while the soil is still managed for pests, most labels specify a replant interval of about 30 days or less. So, replanting within a month aligns with the intended duration of effectiveness and safety for the crop, making it the best choice.

Waiting longer than a month increases the chance of pest resurgence and may violate label restrictions, while replanting immediately could still expose new plants to residual fumigant. Replanting several months or a year later goes beyond practical pest control timing and is not consistent with typical fumigation label requirements.
