Abstract

Inputs, including herbicides, used in crop production may create negative environmental impacts. One solution to minimize these adverse effects is the adoption of integrated weed management (IWM) with the intention of reducing herbicide use. This study, conducted in 2010, estimates the willingness of farmers to pay for the adoption of more effective weed management methods. Results suggest that the willingness to pay (WTP) for IWM is greater than the WTP for other weed management methods, including chemical weed management and chemical and mechanical weed management. This study also identified a number of factors that influence the adoption of IWM on wheat farms in Iran using a multinomial logit model. Total annual income, area under irrigated wheat, wheat yield loss due to weeds, perennial nature of the weeds, and having awareness of weed resistance to herbicides had a positive effect on the adoption of IWM practices. However, having rain-fed (dryland) wheat cultivation and a larger number of plots on the farm had a negative influence on the choice of IWM.

Insumos usados en producción de cultivos, incluyendo herbicidas, pueden generar impactos ambientales negativos. Una solución para minimizar estos efectos adversos es la adopción del manejo integrado de malezas (IWM) con la intención de reducir el uso de herbicidas. Este estudio, realizado en 2010, estima la disponibilidad de productores de pagar (WTP) por la adopción de métodos de manejo de malezas más efectivos. Los resultados sugieren que la WTP por IWM es mayor que la WTP por otros métodos de manejo de malezas, incluyendo el manejo químico de malezas y la combinación de manejo químico y mecánico. Este estudio también identificó un número de factores que influencian la adopción de IWM en fincas de trigo en Irán usando un modelo logit multinomial. El ingreso total, el área de trigo bajo riego, la pérdida de rendimiento del trigo debido a malezas, la naturaleza perenne de las malezas, y el conocer sobre la resistencia de las malezas a los herbicidas tuvo un efecto positivo sobre la adopción de prácticas de IWM. Sin embargo, el tener trigo dependiente de lluvia (sin riego) y un número grande de parcelas en la finca tuvo una influencia negativa sobre la escogencia de IWM.
