late blight, caused by phytophthora infestans, is one of the most important diseases of potato in the world and iran, especially in golestan province. 16 models have introduced for forecasting the disease in the world, sofar. in order to developing a forecasting model, wether and disease occurrence data during the recent 10 years were used.then, 22 variables were built using daily temperature, ...

A decision support system (DSS) for potato and tom ato late blight m anagem ent has been developed to provide disease m anagem ent recom m endations. The system is com prised of two disease-forecasting tools as well as a simulator. Results from simulation and field experim ents w ith the system have shown that the DSS schedules on moderately susceptible crops did not achieve sufficient disease ...

Tanaman kentang adalah tanaman yang dapat berkembang biak secara vegetatif melalui umbi. Kentang mempunyai peranan cukup penting untuk dimanfaatkan sebagai usaha. Penurunan produksi 80% diakibatkan oleh penyakit mengakibatkan penurunan maksimal karena terjadi penghambatan pertumbuhan. Early blight dan late merupakan umum menyerang kentang. Penyakit tersebut diidentifikasi bercak warna pada daun...

The central highlands of Mexico are considered to be a center of genetic diversity for both the potato late blight pathogen and for tuber-bearing Solanum spp. Recent work conducted in Mexico and South America sheds new light on the biology and evolution of Phytophthora infestans and other related Phytophthora pathogens. It now appears that Mexican Solanum species, which coevolved with P. infest...

The ability of two different flow cytometers, the Microcyte (Optoflow) and the PAS-III (Partec), to differentiate sporangia of the late-blight pathogen Phytophthora infestans from other potential airborne particles was compared. With the PAS-III, light scatter and intrinsic fluorescence parameters could be used to differentiate sporangia from conidia of Alternaria or Botrytis spp., rust uredini...

Resistance to pathogens is essential for survival of wild and cultivated plants. Pathogen susceptibility causes major losses of crop yield and quality. Durable field resistance combined with high yield and other superior agronomic characters are therefore, important objectives in every crop breeding program. Precision and efficacy of resistance breeding can be enhanced by molecular diagnostic t...

The late blight pathogen Phytophthora infestans can attack both potato foliage and tubers. When inoculated with P. infestans, foliage of nontransformed 'Russet Burbank' (WT) develops late blight disease while that of transgenic 'Russet Burbank' line SP2211 (+RB) does not. We compared the foliar transcriptome responses of these two lines to P. infestans inoculation using an RNA-seq approach. A t...

Late blight, caused by Phytophthora infestans, is the main constraint to tomato production and exportation in Cameroon. The objective of this study was evaluate impact chemical varieties control blight field for improvement west region Seedlings 7 produced nursery were transplanted into pits each containing 100 g fowl droppings 30 nematicide Carbofuran 5%. From 21st day after transplanting, dif...
