The energetic component is the chemical component in the pesticide item that regulates the insect. By understanding the difference in poisoning levels of pesticides, a user can decrease the potential threat by picking the chemical with the most affordable toxicity that will certainly manage the parasite.


However, applicators can reduce or virtually remove exposure-- and hence reduce danger-- by complying with the label instructions, utilizing individual safety garments and tools (PPE), and handling the chemical properly.

The reduced the LD50 or LC50 worth of a chemical item, the greater its toxicity to human beings and pets. Pesticides with a high LD50 are the least hazardous to people if utilized according to the directions on the item label. The persistent toxicity of a chemical is established by subjecting test animals to long-lasting exposure to the active ingredient.
