Sharifzadeh MS, Abdollahzadeh G. Do typologies of pesticide risk knowledge influence the adoption of IPM strategies? Evidence from rice farmers' behavior in northern Iran. PEST MANAGEMENT SCIENCE 2024; 80:4427-4436. [PMID: 38676571 DOI: 10.1002/ps.8151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 04/14/2024] [Accepted: 04/27/2024] [Indexed: 04/29/2024]
Abstract
BACKGROUND The active participation of farmers in adopting eco-friendly practices is vital to mitigate the environmental and health risks linked to pesticide usage. Farmers' awareness of these risks significantly influences their adoption of integrated pest management (IPM) methods over traditional pesticide applications. This study sought to explore the range of understanding on pesticide effects, categorize IPM strategies employed in pest management, and examine the correlation between knowledge levels and IPM strategy choices. Data was gathered through structured questionnaires from 391 rice farmers in Sari County, Mazandaran province, Northern Iran. RESULTS Exploratory factor analysis revealed three distinct dimensions of pesticide risk knowledge: personal risk of pesticide, environmental risk of pesticide, and community risk of pesticide. Furthermore, the study identified three primary categories of IPM strategies: high familiarity, intermediate familiarity, and low familiarity. The results of the regression analysis indicated that the personal risk of pesticides (β = 0.556; P < 0.01) and the environmental risk of pesticides (β = 0.262; P < 0.01) are significantly correlated with the adoption of high familiarity IPM strategies. Furthermore, the study revealed that there was no significant statistical evidence to support the notion that different types of pesticide risk knowledge had any influence on the adoption of intermediate and low familiarity strategies. CONCLUSION The findings of this study imply the critical importance for agricultural extension programs to focus on enhancing farmers' knowledge of pesticide risks and various IPM strategies. © 2024 Society of Chemical Industry.

Abstract
Precision and efficient pesticide spraying is an important part of precision agriculture, banana is a large broad-leaved plant, with pests and diseases, has a high demand for spraying and pest control. The purpose of this study was to clarify the wettability of different pesticides on the banana leaf surface, and the effects of nozzle type and working parameters on the deposition distribution performance under air-assisted spray conditions. The wettability test results of different pesticides on banana leaf surfaces showed that the wettability of the adaxial side was always stronger than that of the abaxial side, the smaller the surface tension of the droplets, the better the wettability on the surface. The spray experiment was carried out on the previously developed air-assisted sprayer with the latest developed intelligent variable spray control system. Three types of nozzles were used to spray with different combinations of working parameters. The deposition distribution performance on the banana leaf surface was obtained by image processing using a self-compiled program. The experimental results show that the nozzle type, wind speed, and spray pressure have significant effects on the deposition distribution performance. Through the study of the interaction and coupling effect of nozzle type and working parameters on the spray droplet deposition distribution on both sides of banana leaves, the results show that under the conditions of hollow cone nozzle, 0.5Mpa spray pressure and 3-5 m/s wind speed, the spray coverage and droplet density are in the optimal state. This is mainly due to the low spray pressure and/or wind speed is not enough to make the banana leaves vibrate and improve the performance of pesticide deposition. excessive spray pressure and/or wind speed will cause large deformation of banana leaves and make them airfoil stable, which reduces the surface deposition performance. It is of great significance for promoting sustainable and intelligent phytoprotection.

Abstract
Background Pesticides are widely used around the world. However, these chemicals are being used more frequently and at increased doses in underdeveloped and developing countries. Although the hazard of pesticides has been studied in ecological fields, the effect of residual amounts of these compounds on the physiological processes of the body has always been debated. Materials and Methods In this experimental study, 45 greenhouse cucumber plants were sprayed with dichlorvos and acetamiprid pesticides in concentrations of twofold (acetamiprid 500 g/1000 L and dichlorvos 4 L/1000 L) and threefold of the recommended dose. After 24 h, the residual amount was obtained. To evaluate the residual effect of the mentioned pesticides, an equivalent of this residue was added to the drinking water of 105 mice. Results Pesticide residues were obtained for twofold and threefold concentrations of the recommended dose, 1.5 and 2.5 (mg/kg cucumber) for acetamiprid and 0.5 and 1 (mg/kg cucumber) for dichlorvos, respectively. Application of these chemicals at higher doses not only significantly reduced the body weight, food consumption, testosterone production, testicular germ cells and embryo numbers, but also increased the levels of follicle-stimulating hormone and luteinizing hormone in mice. Conclusions The emergence of biological disorders and reducing reproductive potential in male mice can be attributed to the addition of pesticides to their drinking water. Therefore, to reduce the hazards caused by insecticides, it is recommended to familiarize farmers with the harmful effects of overdose of pesticides and monitoring the residuals in agricultural products.

Abstract
OBJECTIVE This cross-sectional study aimed to examine farmers' knowledge, awareness, practices regarding pesticide use, and prevalence of health symptoms related to pesticides exposure among farmers who applied organophosphates (OP) and pyrethroids (PY). METHODS Data regarding demographic variables and health symptoms pertinent to pesticide use was collected from 67 farmers who applied OP and 50 farmers who applied PY using interviews from January to March 2021. RESULTS The farmers who applied OP had lower knowledge, awareness, and prevention practices regarding pesticide use than those who applied PY. After adjustment of covariate variables, the farmers who applied OP had a significantly higher prevalence of respiratory conditions (OR = 8.29 for chest pain, OR = 6.98 for chest tightness, OR = 27.54 for dry throat, and OR = 5.91 for cough), neurological symptoms (OR = 10.62 for fatigue and OR = 6.76 for paresthesia), and neurobehavioral symptoms (OR = 13.84 for poor concentration, OR = 3.75 for short term memory, and OR = 8.99 for insomnia) related to pesticide exposure than those who applied PY. CONCLUSION Our findings suggest that OP had a more adverse effect on human health than PY, resulting in a higher prevalence of pesticide-related symptoms. The outcomes of this study have the benefit of providing vital information for all stakeholders with regard to the implementation of safe practices in the utilization of personal protective equipment (PPE) and pesticide use in a health intervention and health promotion program.

Abstract
INTRODUCTION Playful learning for environmental education represents a participatory pedagogical mediation that considers the socio-environmental realities in which persons are immersed. OBJECTIVE To promote environmental education, through playful, participatory, and flexible methods, to prevent pesticide exposure. METHODOLOGY Using geographic information systems, the distances between schools and bananas plantations were calculated. A playful and constructivism methodology was designed for primary school students (6 - 8.5 years), and their legal guardians. Subsequently, 148 workshops were developed in 37 rural Costa Rican schools, in which 2757 children and 387 adults participated. RESULTS Thirty-eight percent (38 %) (n=14) of the schools were located at less than 100 meters from banana plantations. Playful communication generated a participatory environment, in which local needs were identified and collective knowledge was built about the effects of pesticide exposure on the environment and human health. Participants were able to identify the main preventive actions to reduce pesticide exposure. CONCLUSIONS Playful, participatory, and flexible methodologies in environmental education facilitate the process of sensitizing first cycle primary school students and their parents from rural communities about the risks of exposure to pesticides. The methodology used can be easily adapted for application in other environmental science studies.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 773:145615.

Abstract
Pesticides are often applied multiple times during cucumber cultivation in China. In order to obtain the residue concentrations and subsequently human health risk assessment after pesticide multiple applications, plenty of field trials have been conducted, consuming a lot of labor force and funds. The application of kinetic models can address this problem to some extent by predicting the residue values of pesticides in cucumber. In this study, a dynamic model (dynamiCROP) was applied in combination with field experiments to investigate the distribution, translocation, and dissipation after the one-time application of seven pesticides in a cucumber-soil environment. Moreover, the residue concentrations after the second and third applications of the seven pesticides were estimated through a "simple superposition method", i.e., superimposing the output results of dynamiCROP after each single pesticide application. The estimated residue concentrations show good agreement with that measured through field experiments with R2 = 0.865 and relative root mean squared error (RRMSE) = 13.2%. Meanwhile, the short- and long-term risks of each pesticide were assessed according to the concentrations estimated by the "simple superposition method" with the dynamiCROP model. It shows that the seven pesticides, applied multiple times during cucumber cultivation, pose a very low dietary risk to human health through cucumber intake. Our study presents a cost- and time-efficient way to investigate the dissipation of pesticides in the cucumber-soil environment, predicate the residue concentrations of pesticides after multiple applications and assess the dietary risk of pesticides to human health through cucumber intake.
