Perceptions and Beliefs about Weed Management: Perspectives of Ohio Grain and Produce Farmers

Abstract

Experts have long sought to understand the factors that underlie farmer decision making for weed management. The majority of this interest has been in relation to the weak adoption of integrated management approaches and more recently, herbicide resistance strategies. In order to increase adoption in these contexts there is a need to understand better the underlying drivers for weed management decisions. The objective of the research reported here was to probe farmers' understanding of weed management to establish a baseline understanding of these key drivers. Thirty Ohio farmers participated in an in-depth interview where they were asked to reflect on how weeds are introduced and spread, what risks and benefits weeds pose, and what management strategies farmers are familiar with and which they prefer. Their responses were mapped, coded, and analyzed for dominant beliefs and major decision-making influences. The results indicate that farmers largely attribute the introduction and movement of weeds to factors outside their control (e.g., the environment, plant characteristics). They frequently cite diverse and integrated management, but their focus is on control as opposed to prevention. In general, they tend to receive messages about integrated and preventive approaches, but do not always put them into practice because of underlying beliefs about the inevitability of new weed introductions and spread.

Alternativas de controle químico do capim-amargoso resistente ao glyphosate, com herbicidas registrados para as culturas de milho e algodão

“…Atrazine, isoxaflutole, S-metolachlor, clomazone, diuron and flumioxazin presented themselves as effective pre-emergents for controlling this species. Keywords: resistance, associations, graminicides, pre-emergence, post-emergence plantas daninhas resistentes está além de suas capacidades (Wilson et al, 2008); (iii) outros agricultores acreditam que a indústria criará novos herbicidas capazes de controlar biótipos resistentes (Llewellyn, 2007). Em todos os casos os agricultores estão equivocados.…”

Global Status of Herbicide Resistance Development: Challenges and Management Approaches

“…2 is logically recommendation to control herbicide resistant weeds. Some growers believe that mitigating herbicide weed-resistant is beyond their control, depending more on their neighbor's behavior (Llewellyn and Allen, 2006;Wilson et al, 2008). Growers may also believe that industry will develop new formulations of herbicides, decreasing the benefits of resistance management (Llewellyn et al, 2002;Llewellyn, 2007).…”

La gestione integrata delle malerbe: un approccio sostenibile per il contenimento delle perdite di produzione e la salvaguardia dell’ambiente

“…Gli interessi, convergenti in questo caso tra agricoltori ed industria, fanno ben sperare che almeno in questo ambito gli agricoltori possano essere spinti a scegliere sistemi gestionali virtuosi. Wilson et al (2008) sottolineano che salvaguardare l'efficacia degli erbicidi prevenendo l'insorgenza della resistenza è uno dei principali obiettivi dell'IWM. Llewellyn et al (2007) evidenziano in questo ambito la necessità di una approfondita valutazione economica della gestione della resistenza, soprattutto per quanto riguarda i costi delle misure di prevenzione.…”
