What should you do if you encounter dense pest populations in the soil before fumigation?

When encountering dense pest populations in the soil before fumigation, delaying or adjusting the fumigant application is the most appropriate course of action. Dense pest populations can indicate that the infestation is more severe than initially understood, which might require a different strategy to ensure effective pest control.

Adjusting the fumigation plan allows for several considerations, such as increasing the dosage to achieve greater effectiveness or modifying the application method to ensure proper penetration into the soil where pests are concentrated. Delaying application also provides an opportunity for further assessment of the situation, allowing for a more informed decision on how best to proceed with the fumigation process.

Other actions, such as proceeding with the original plan, using double the amount of fumigant, or switching to a different pesticide, may not adequately address the issue of dense pest populations. They could potentially result in ineffective pest control or unintended consequences, such as environmental harm or resistance development. Therefore, the best practice is to delay or adjust the fumigant application based on the current pest density to ensure successful outcomes.
