Molecular genetics of pathogenic oomycetes
Parasitic and pathogenic lifestyles have evolved repeatedly in eukaryotes (93). Several parasitic eukaryotes represent deep phylogenetic lineages, suggesting that they feature unique molecular processes for infecting their hosts. One such group is formed by the oomycetes. Traditionally, due to their filamentous growth habit, oomycetes have been classified in the kingdom Fungi. However, modern ...

Potato Late Blight, Lelystad, Netherlands - Case Study
Late blight, caused by Phytophthora infestans, is the most important disease in potato production. Under favourable conditions the pathogen can destroy the potato foliage very rapidly and cause tuber blight. To avoid infection of the foliage, fungicides are frequently sprayed onto the crop. In the Netherlands, in some years up to 15 sprays are necessary to prevent the crop from infection by the ...

Inheritance and genetic mapping of resistance to Pythium damping-off caused by Pythium Aphanidermatum in ‘Archer’ soybean
Pythium damping-off and root rot of soybean [Glycine max (L.) Merr.] causes poor stands and consequently reduces yields. Resistance to seedling diseases caused by Pythium spp. was reported in the soybean cultivar Archer and was described to be associated with the Rps1k gene for resistance to Phytophthora sojae. To characterize the inheritance of Pythium damping-off resistance in Archer and to ...

Top 10 Tips To Improve Plant Quality
1) Venting – it’s crucial to keep air movement and temperatures at the optimum levels. 2) Watering at the right times – and just importantly in the correct fashion! Make sure plants are grown nearby those with similar needs so plants with a need for a lot of water will be apart from those with dryer needs. 3) Keep roots strong – as fertilizers are applied and plants grow, ...

The influence of biowaste and garden waste composts on diseases caused by pythium ultimum and rhizoctonia Solani related to the antagonists trichoderma hamatum and flavobacterium balustinum
Soilborne plant pathogens can cause serious losses on both agricultural and horticultural crops. Examples include damping-off diseases caused by Pythium spp. and Rhizoctonia spp., Pythium and Phytophthora root rots, Rhizoctonia crown rot, Fusarium and Verticillium wilts, nematode and even bacterial diseases. Until the fifties, the principal methods to control soilborne diseases were through the ...

Crop protection 2.0: reducing environmental impact in the EU Is it feasible?
By 2023 all EU member states must be complying with more stringent guidelines related to Integrated Pest Management (IPM). “The essence of the new guideline is reducing the environmental impact of pesticides,” says Piet Boonekamp, manager of the Bio-interactions and Plant Health business unit at Wageningen UR. “In principle this European goal can be achieved, as has been shown ...

Summer Irrigation Makes the Crop
Summer Irrigation Makes the Crop Summertime. At this point in the growing season, fruit for tree and vine crops has long been set. Now, the challenge is to bring as much of this yield potential to harvest, and at the desired quality. Irrigation management is crucial to achieve this goal. For most crops, irrigation should provide readily available soil moisture continuously so that fruit and ...

Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...
