Pierwsze próby wykorzystania Internetu dla potrzeb monitorowania zagrożenia ziemniaka przez P. infestans w Polsce podjęto w latach 2001-2002 z zastosowaniem oprogramowania przekazanego stronie polskiej przez Duński Instytut Nauk Rolniczych. Istotny wkład w opracowanie rodzimego systemu internetowego wniosła również współpraca Instytutu Ochrony Roślin z Centrum Oprogramowania i Systemów Decyzyjnych...
Przedstawiono pierwszy w Polsce niekomercyjny system wspomagania decyzji w ochronie ziemniaków, dostępny i funkcjonujący dzięki Internetowi. Omówiono schemat funkcjonowania, sposób korzystania i możliwości jego rozbudowy oraz udoskonalania. Korzystanie z tej formy pomocy w określeniu właściwych terminów zabiegów zwalczania sprawcy zarazy ziemniaka (Phytophthora infestans) pozwoli uzyskać wyższą skuteczność...
Measurements of spectral reflectance from potato plants were carried out in the years 2000 and 2001 using the field radiometer CE 313 of Cimel Electronique Company. Field experiments permitted to perceive differences in the reflectance of electromagnetic radiation from potato plant cultivars Bekas and Mila as well as differences between the plants treated with fungicides providing the protection against...
In the field experiments performed in 1999–2001 the profitability of late blight control in accordance with three decision support systems: NegFry,Simphyt and Stephan with routine fungicide program was compared. Potato protection carried out according to the recommendations of the decision support systems guaranteed higher profitability of late blight control than when potato was protected routinely...
Two potato cultivars, sprayed and nonsprayed with fungicides, were evaluated to determine the association of late blight (caused by Phytophtora infestans) and radiometric leaf reflectance to disease development. Spectral radiance measurements were taken with CIMEL CE3132 luminancemeter in the visible (450 nm, 550 nm and 650 nm) and near-infrared (850 nm) range of the electromagnetic spectrum. The...
