PROPHY | Late blight and Early blight | PROPHY is developed and marketed by Opticrop (now Agrovision) for farmers and advisors. Local weather stations and regional weather forecasts are used to identify critical conditions for the development of blight. The duration of protection of the crop with fungicides is calculated. The duration of protection depends on the fungicide used, the dose rate, the variety resistance, rainfastness of the fungicide, the disease pressure, and the growth of the crop. In combining weather and protection with fungicides a recommendation is calculated: a preventative spray is necessary as soon as critical conditions are expected in combination with an insufficient level of fungicide protection of the crop. The system provide a complete advice (yes/no spray, product choice and dose rate). | Erno Bouma

MILEOS | Late blight | Mileos ® is a web-based, on-farm Decision Support System (DSS) available to potato growers to control potato late blight (LB) caused by Phytophthora infestans. It results from collaboration between ARVALIS and the French Ministry of Agriculture. The two pre-existing DSS’s (MILPV and Mildi-LIS®) have been fused, in 2009, into an optimized tool, entirely reviewed and up-dated in order to better meet national demand and help farmers to comply with EU regulations. With Mileos® (see www.mileos.fr), the fungicide application on potato crops is optimized, triggered according a real-time LB risk assessment taking into account environmental data (climatic and disease pressure), agronomical data such as cultivar’s LB resistance and crop health practices for potato fields such as chemical input, cultivar choice and irrigation. | Dennis Gaucher

SIMPHYT | Late blight | SIMPHYT is developed by ZEPP and provided by ISIP e. V. for farmers and advisors. SIMPHYT 1 recommends on the spray start whereas SIMPHYT 3 provides indications for the disease pressure and advises on follow-up sprays. The input data used are weather information, variety and emergence date. The model can also calculate advises for extra risky situations such as fields close to infection sources or fields with very wet conditions. A nationwide network of untreated and treated plots is used to monitor the presence of late blight. In 2010 Öko-SIMPHYT an expansion for organic potato production will be provided. The system recommends the timing and amount of copper-hydroxid follow up spays. | Benno Kleinhenz

Blight Watch | Late blight | The Blightwatch service uses the Hutton Criteria to calculate blight risk across the UK. Using UK Met Office forecast data for thousands of forecast points, the Blightwatch service provides warning indications up to 24 hours ahead of potential Hutton Criteria. Alerts are generated and sent to users based on the warning criteria or when there has been a blight outbreak confirmed through the AHDB Potatoes ‘Fight Against Blight’ service for a selected region. The Blightwatch alerts do not constitute a recommendation to spray but provide an early warning to aid management decisions around spray timing and intervals. Blightwatch is supported by The Agricultural and Horticultural Development Board (AHDB Potatoes) and operates in conjunction with their ‘Fight Against Blight’ (FAB) service. It also relies on support from agro-industry sponsors. | Claire Hodge, AHDB Potatoes Knowledge Exchange Manager - Scotland e: Claire.Hodge@ahdb.org.uk (link sends e-mail) ¦ t: 07771 798 552 |

VNIIFBlight | Late blight | The VNIIFBlight system was developed in the All-Russian Research Institute of Phytopathology for the farmers and advisors, working in the potato production industry. The model identifies the image of the weather, favourable or unfavourable for the outbreaks in the LB development. Together with a 5-day weather forecast, it provides the information about the optimum time of treatments.
A simple computer program is available for potato growers in the Internet. Each treatment should be applied in accordance with the VNIIFBlight recommendations, but the repeated treatments should be applied not earlier than 7-10 (susceptible cultivars) or 11-14 (resistant cultivars) days after the previous treatment. A cultivar is considered to be susceptible or resistant if its LB resistance is < 5 or > 5 scores, respectively (using a 9-score scale). | Alexey Filippov

 | Irish rules | Met Éireann (Irish Meteorological Service) is issuing blight warnings guided by outputs of algorithm proposed by Bourke (1953), known as Irish Rules. Blight risk is expressed in effective blight hours which are calculated using observed weather data and ten day weather forecast (ECMWF and HILRAM models). Model outputs are used as synoptic weather forecasting guide to weather forecasted on duty. Blight warnings include information about areas affected, duration of spell, and opportunities for spraying, where possible. Warning service is operational from May to September through Met Éireann web page and android app (www.met.ie), daily radio and television broadcast, and email. | Mladen Cucak

Nærstad model | | Calculations of risk values are based on sub-models for the different steps in the disease cycle like spore production, spore release, spore survival and infection of spores. The model criteria for spore production is long humid periods and at moderate humidity sporulation is reduced. The amount of viable attached sporangia is reduced by drought, and some spores are washed off during rain. The model criteria for spore release into the air is a drop in humidity or increased radiation, but the release is inhibited by high leaf wetness. The model includes criteria for spore survival and the viability of released spores is strongly inhibited by solar radiation. The spore load is also reduced by precipitation. The criteria for infection is that leaf wetness duration has to be sufficient for the spores to germinate and infect. The risk of blight development is a function of the amount of viable released spores and the duration of leaf wetness. The model outputs are based on the assumption that inoculum is available in the field, and is meant to provide information for optimal timing of pest management strategies. | Håvard Eikemo & Anne-Grete Roer Hjelkrem Norwegian Institute of Bioeconomy Research (NIBIO) haavard.eikemo@nibio.no Anne-Grete.Hjelkrem@nibio.no |
