What action should be taken if moisture levels in soil are higher than normal?

When moisture levels in the soil are higher than normal, considering delaying the application of fumigants is the most prudent course of action. Increased soil moisture can significantly affect the efficacy of the fumigants. High moisture levels may result in the fumigant being less effective in penetrating the soil and reaching the target pests, as excess water can create barriers and reduce gas diffusion. Additionally, excessive moisture can lead to the fumigant reacting with water, which may alter its chemical properties and reduce its effectiveness.

Fumigation relies on the fumigant being able to diffuse evenly through the target area, and excessive moisture can hinder this process. Therefore, postponing the application until soil moisture levels are more optimal ensures that the treatment will be more effective and safer.

Proceeding with the fumigation as scheduled, increasing the fumigant dosage, or using only solid fumigants do not address the underlying issue of elevated moisture levels and may lead to ineffective pest control or potential environmental risks.
