“…More specifically, the Danish DSS CPO is a threshold-based system that determines economically viable strategies for control of diseases, pests and weeds using low pesticide input (Secher et al 1995;Rydahl 2003). The system is designed to support advisors and farmers when they make decisions about crop protection in arable crops.…”

Plant pathologists have traditionally worked in the area of clarifying and understanding the disease cycles of specific diseases, factors influencing epidemiology, yield loss potential and host-pathogen interactions in order to be able to minimise the disease risk, build warning systems or recommend specific control thresholds in relation to the application of fungicides. The decision support system Crop Protection Online (CPO) is an example of a threshold-based system that determines economically viable fungicide strategies. The system is based on using appropriate doses aimed at minimising the overall pesticide input. CPO is used widely by advisors and many of the thresholds are generally accepted and disseminated through newsletters. The national figures for the use of fungicides in cereals have shown a major reduction during the last 20 years and their use today is much in line with the level that can be achieved from using CPO as indicated from validation trials. The number of end-users among farmers has been stable at around 3% during the last 10 years (800-1,000 farmers). Major hurdles in increasing the number of users are believed to be: (1) the requirements for carrying out assessments in the field, (2) farm sizes getting larger, leaving less time for decision making for individual fields, (3) lack of economic incentives to change from standard treatments, (4) the failure of decision support systems to interact with other computer-based programmes on the farm, (5) the lack of compatibility of decision support systems with farmers' ways of making decisions on crop protection in general, (6) the need for direct interactions with advisors. A sociological investigation into the farmers' way of making decisions in the area of crop protection has shown that arable farmers can be divided into three major groups: (a) systems-orientated farmers, (b) experienced-based farmers and (c) advisory-orientated farmers. The information required by these three groups is different and has to be looked at individually from the end-user's perspective rather than from the scientist's perspective. New ways of entering the decision support system where specific Eur J Plant Pathol (field inspections are omitted and where regional disease data are relied on, have been investigated and tested in field trials. The results show possibilities for further developments in that direction, which might be one way of gaining more end-users.

“…Each of these methodologies addresses a particular area of concern, such as groundwater (Gustafson 16 ) or application equipment (Parkin et al 17 ). Some systems are wider in their application such as the Danish PC Crop Protection system (Secher et al 18 ) which addresses many issues associated with crop applications and the efficacy of pesticides. The computerised system being described in this paper, offers a broader approach still and considers a wide variety of parameters seen to effect the fate and transport of pesticides in the environment.…”

A computer-based decision support system is described which aims to encourage and enhance sound environmental management within agriculture. Part of the system focuses on the management of pesticides on the farm, and can help to ensure that the farmer adopts practices which maximise crop production and profitability without jeopardising the environment. The approach taken looks at all aspects of farm pesticide use including crop applications, storage and waste disposal and the use of non-crop pesticides.As a whole, the system can act as a informal environmental management system. An eco-rating is derived by comparing actual farm practices with what is perceived to be best practice for the site, to provide a measure of environmental performance. The first time the method is used these indices act as bench-marks against which the success of future improvements can be judged.The system has three modes of operation. An "assessment mode" seeks to identify strengths and weakness in practices and regulatory compliance and to provide guidance on areas where improvements could be made. In support of this a second mode known as the "technical system" allows the user to explore 'what-if' scenarios in order to identify site specific best practice and aims to provide answers to the issues raised in the assessment mode. The third mode is a fully integrated hypertext information system containing a range of context-sensitively mapped text on agriculture and the environment which can be used on a stand-alone basis or accessed from any part of the software system.

Decision support systems: barriers and farmers’ need for support*

The highly complex knowledge of scientific disciplines makes nuanced analysis and modelling possible. However, the information produced often does not reach farmers because it is presented in a way that does not correspond to the way their work is carried out in practice. The decision support system Crop Protection Online is widely used by advisors and as a learning tool for students. Although the system has been validated in many field trials over the years and has shown reliable results, the number of end‐users among farmers has been relatively low during the last 10 years (approximately 1000 farmers). A sociological investigation of farmers’ decision‐making styles in the area of crop protection has shown that arable farmers can be divided into three major groups: (a) system‐orientated farmers, (b) experience‐based farmers and (c) advisory‐orientated farmers. The information required by these three groups to make their decisions varies and therefore different ways of using decision support systems need to be provided. Decision support systems need to be developed in close dialogue and collaboration with user groups.
