What might labels recommend adding to the tank mix with pesticides?

  1. Pure water only

  2. Adjuvants like surfactants and buffers

  3. More active ingredient

  4. Non-related chemicals

The correct answer is: Adjuvants like surfactants and buffers

Labels might recommend adding adjuvants like surfactants and buffers to the tank mix with pesticides because they can improve the effectiveness and efficiency of the pesticide. Adding pure water only (A) may not provide enough mixing and spreading of the pesticide, resulting in uneven coverage and potentially reducing its efficacy. Adding more active ingredient (C) can be harmful to the environment and increase the risk of resistance in pests. Adding non-related chemicals (D) can also be harmful to the environment and have unpredictable effects on the pesticide. Therefore, adjuvants like surfactants and buffers are the recommended additive for a pesticide tank mix.
