1) Four ways of classifying pesticides are: By target pest: This classifies pesticides based on the type of pest they control (e.g., insecticides for insects, herbicides for weeds, fungicides for fungi, rodenticides for rodents). By chemical composition: This groups pesticides based on their chemical structure (e.g., organophosphates, carbamates, pyrethroids, neonicotinoids). By mode of action: This categorizes pesticides by how they affect the pest (e.g., contact poisons, stomach poisons, systemic poisons, respiratory poisons). By formulation: This classifies pesticides based on how they are prepared for application (e.g., wettable powders, emulsifiable concentrates, granules, dusts). 2) Four factors that affect the efficiency of pesticides are: Environmental conditions: Factors like temperature, humidity, rainfall, and wind can affect pesticide degradation, drift, and uptake by pests or plants. Pest characteristics: The life stage, mobility, population density, and resistance level of the target pest influence how effective a pesticide will be. Application method: The technique used to apply the pesticide (e.g., spraying, dusting, soil incorporation) and the coverage achieved can significantly impact its efficiency. Pesticide properties: The inherent toxicity, persistence, solubility, and formulation of the pesticide itself determine its effectiveness.
