Knowing the residues left by pesticides is crucial for several reasons. Understanding the effectiveness of a pesticide can help determine whether it succeeded in controlling the targeted pests and if the application rate was appropriate. Additionally, regulatory compliance and safety are significant considerations since there are established guidelines regarding acceptable residue levels to protect human health and the environment. Finally, knowing the residue levels is vital when determining the appropriate waiting period before harvesting crops to ensure that pesticide levels are below permissible limits, which helps avoid potential health risks associated with consuming produce that may have pesticide residues. Hence, all of these aspects are interconnected and collectively emphasize the importance of being aware of pesticide residues.
