This descriptive study was conducted in 2019-2020 aiming to investigate the knowledge of farmers and gardeners about the use of pesticides in greenhouses in Tiran -Karvan County, central Iran. In the first stage, a 30-item questionnaire was developed which included parameters such as the application time, the dose, and the side effects of pesticides and the Pre-Harvest Interval (PHI). Out of a total of 450 greenhouses in the area, 50 greenhouses that were selected through the simple random sampling method filled out the questionnaire. The collected data were analyzed and compared in SPSS. According to the results, whiteflies were the most common pests in greenhouses. The pests were mostly identified by an expert. The most important side effects of pesticides among greenhouse owners in Tiran -Karvan County were burning and itching (52%), cough and sneezing (30%), and sensitivity (18%); 76% of greenhouse owners observed the PHI for their products; and 92% of greenhouse owners used Personal Protective Equipment (PPE). Public and private education, increasing the knowledge of greenhouse owners about the hazards of pesticides, the use of PPE, and observing the principles of environmental health by implementing new and up-to-date educational programs are essential.
