The poisoning of a particular pesticide is established by subjecting examination animals to varying does of the active ingredient (a.i.) and each of its developed products. The energetic ingredient is the chemical part in the pesticide product that controls the parasite. By understanding the distinction in poisoning levels of chemicals, a customer can reduce the possible danger by selecting the pesticide with the most affordable poisoning that will certainly control the parasite.


Nonetheless, applicators can reduce or virtually get rid of direct exposure-- and hence lower hazard-- by following the tag directions, making use of personal safety clothes and equipment (PPE), and taking care of the pesticide effectively.

Furthermore, the LD50 and LC50 values are based on a solitary dosage and are recorded in milligrams of chemical per kg of body weight (mg/kg) of the test pet or in components per million (ppm).


The lower the LD50 or LC50 value of a pesticide product, the higher its toxicity to humans and pets. Pesticides with a high LD50 are the least poisonous to human beings if utilized according to the directions on the item label. The chronic toxicity of a pesticide is established by subjecting guinea pig to lasting exposure to the active ingredient.


The persistent poisoning of a pesticide is more difficult than severe toxicity to establish through research laboratory evaluation.
