Dacom, PLANT-PLUS

Late blight and Early blight PLANT-PLUS is developed and marketed by Dacom BV for farmers and advisors. The model supplies information about the optimum time to spray and the type of fungicide to use. A starting point in the model is provided by the protection offered to the crop by the previous spraying, in combination with the risk of disease infections occurring. In a clear presentation, the calculation is accounted for each step of the way, and presented by a graph and a report. With input of weather data like temperature, wind speed, rainfall and humidity combined with input of the grower on crop conditions, Plant-Plus calculates when an infection event occurs. This result in a crop protection advice: when to apply a new spray and what type of chemical to use. Louis Nannes

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 developed by the French Plant Protection Service (SRPV) and Arvalis for farmers and advisors. It contains 2 models. MILPV is based on the MILSOL forecasting model. MILDI LIS is based on the Ullrich and Schrodter negative prognosis. The models supply information about the optimum time to spray and the type of fungicide to use in a range of varieties with different resistance levels. MILPV also has a version for organic potatoes. Maps with infected fields are provided. Ludovic Dubois

NEGFRY

Late blight NEGFRY is developed in field experiments in a few agricultural institutes (IHAR-Bonin, IUNG -Pulawy, IOR-Pozna?) and fields of Protection Services since 2001, after cooperation in project with DIAS, Now AU, Denmark. The model supplies information about the optimum time to spray and the type of fungicide to use. A starting date of the protection is accessible for all farmers in Internet, based on nearest synoptic weather station data and calculated by NegFry. Jozefa Kapsa

I, IPI & MISP

Late blight and Early blight IPI and MISP are used to forecast the appraisal and evolution of late blight infections on potato and tomato, in the Emilia-Romagna region (Servizio Fitosanitario Emilia-Romagna). Model IPI (Indice Potenziale Infettivo) and Model MISP (Main Infection and Sporulation Period). Model IPI is informative about the occurrence of the disease and advises if it is necessary (and when) to start with the first spray, based on a series of climatic parameters. It was set up in 1990 and is used together with the Model MISP, developed in Switzerland, which provides indications on the following infective events. Riccardo Bugiani

Blight Management

Late blight BLIGHT MANAGEMENT is operated by the Aarhus University (AU), the Danish Agricultural Advisory Service (DAAC) and the Danish Meteorological Institute (DMI). It integrates all available information about late blight control, including tools like monitoring of early attacks, weather based late blight infection pressure, general weather information and -forecast, regional blight weather and -forecast, fungicide information, cultivar database with information about late blight resistance etc. The separate DSS components are not integrated to provide specific decisions on timing and use of a specific fungicide type and dosage.

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

Phytophthoramodel-Weihenstephan

Late blight and Early blight Phytophthoramodel-Weihenstephan was developed at the Münich University and is used by Syngenta to inform farmers and advisors. A nationwide network of untreated plots is used to monitor the presence of early and late blight. Information from weather stations is used to indicate blight critical weather. All this information is provided for both early and late blight. The growers and advisors can use this information to design their own spray strategy. Hans Hausladen

PROPLANT

Late blight PROPLANT is developed and marketed by ProPlant GmbH for farmers and advisors. The Expert Classic system is installed with a CD-ROM on the PC and supplies specific field information about the optimum time to spray and the type of fungicide to use. The Expert.Com system provides interactive recommendation on the internet. Thomas Volk

PHYTOPRE

Late blight PhytoPRE is developed by the Research Station Reckenholz-Tänikon ART for farmers and advisors. The interactive internet DSS and LB information system provides daily actualized maps and information on late blight infected fields in Switzerland. Based on regional and local weather data and the 2-day weather forecasts of MeteoSwiss, it shows current and recent information on main infection- and sporulation periods (MISPs). Spraying recommendations are provided based on field specific information, the current disease situation, weather conditions (MISP), used fungicide and level of fungicide protection. The system has modules for integrated and organic potato production (Bio-PhytoPRE with a special module for the timing and acquisition of copper sprays). Hans-Rudolf Forrer/ Tomke Musa

Blight Watch

Late blight The Blightwatch service providers have worked to develop this management tool which is available to farmers and other users free of charge. Traditionally the risk of potato blight infection has been based on the calculation of Smith Periods - a system that uses hourly temperature and relative humidity recordings. However, until now Smith Periods have been calculated for only a limited number of Met stations around the country. The Blightwatch service now covers the whole of the UK down to individual postcode level. The service operates in conjunction with the Potato Councils - Fight Against Blight! - service and delivers daily email and optional SMS alerts if blight risks are identified in your selected area(s).

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).
