1. Pest infestations: Pesticides are often used to control and eliminate pests that can damage crops, spread diseases, or cause harm to humans and animals.
2. Crop protection: Pesticides are used to protect crops from damage caused by insects, weeds, and diseases, which can reduce crop yields and quality.
3. Public health concerns: Pesticides are used to control disease-carrying insects and pests that can pose a threat to human health, such as mosquitoes that transmit malaria or ticks that carry Lyme disease.
4. Environmental protection: Pesticides are used to control invasive species and protect native plants and animals from harm. They can also be used to prevent the spread of diseases that can harm ecosystems.
5. Economic reasons: Pesticides are used to protect agricultural crops and livestock, which are important sources of food and income for many people around the world. Without pesticides, farmers may suffer significant financial losses due to crop damage.
6. Regulatory requirements: In some cases, pesticides are required by law to be used to control certain pests or diseases in order to protect public health and the environment.

Intrinsic Factors within the Active Ingredient
- Chemical structure: Pesticides with certain functional groups (e.g., carbamates, organophosphates) are more prone to degradation.
- Molecular weight: Heavier molecules tend to be more persistent and less likely to degrade.
- Solubility and volatility: Soluble pesticides are more likely to leach into water and be transported to soil where degradation can occur. Volatile pesticides can evaporate into the atmosphere and undergo photodegradation.
Environmental Factors
- Temperature: Higher temperatures generally accelerate degradation.
- Moisture: Water influences the availability of microorganisms and enzymes that promote degradation.
- Soil type: Clayey soils with higher organic matter content provide a more favorable environment for degradation.
- pH: Acidic or alkaline conditions can affect the stability and degradation rate of pesticides.
- Sunlight: Ultraviolet radiation from sunlight can cause photodegradation of some pesticides.
Biological Factors
- Microorganisms: Soil microorganisms (e.g., bacteria, fungi) play a crucial role in pesticide decomposition.
- Enzymes: Enzymes produced by microorganisms and plants can catalyze pesticide degradation reactions.
- Plants: Plant roots can take up and metabolize pesticides, leading to their degradation.
Agricultural Practices
- Application method: The form and method of pesticide application can influence its availability and degradation rate.
- Dosage: Higher application rates can result in slower degradation due to saturation of degradation mechanisms.
- Cropping system: Crop rotation and cover crops can promote soil microbial activity and enhance pesticide degradation.
- Soil management: Tillage practices can affect soil moisture and aeration, influencing pesticide degradation rates.
Other Factors
- Formulations: The addition of adjuvants, solvents, and inert ingredients can alter the stability and degradation characteristics of pesticides.
- Storage conditions: Improper storage can lead to pesticide degradation due to temperature fluctuations or exposure to light.
- Waste management: Disposal of pesticide containers and residues can contribute to environmental contamination and persistence.
