Minimalist AdaBoost for blemish identification in potatoes [PDF]
, 2010 We present a multi-class solution based on minimalist Ad- aBoost for identifying blemishes present in visual images of potatoes. Using training examples we use Real AdaBoost to rst reduce the fea- ture set by selecting ve features for each class, then

Pest categorisation of Synchytrium endobioticum
EFSA Journal, Volume 16, Issue 7, July 2018., 2018 Abstract The Panel on Plant Health performed a pest categorisation of the fungus Synchytrium endobioticum, the causal agent of potato wart disease, for the European Union (EU). The identity of the pest is well established and reliable methods exist for its detection and identification. S. endobioticum is present in most continents.

Pests and diseases affecting potato landraces and bred varieties grown in Peru under indigenous farming system [PDF]
, 2015 The major pests and diseases were identified and quantified on thirteen potato landraces and three bred varieties cultivated in Peru. Late blight (Phytophthora infestans) was the primary biotic constraint affecting plants before flowering with an average

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 Multiple disease resistance is an aim of many plant breeding programs. Previously, novel somatic cell selection was used to generate potato variants of “Russet Burbank” with resistance to common scab caused by infection with an actinomycete pathogen. Coexpression of resistance to powdery scab caused by a protozoan pathogen was subsequently shown.

Susceptibility of Solanum curtilobum to Spongospora subterranea (Wallr.) Johnson [PDF]
Nature, 1951 IT has been stated by Dorojkin1 that Solanum curtilobum and eight other South American species and varieties of Solanum are immune from Spongospora subterranea, the causal agent of powdery scab of potatoes; in this paper the number 8008 is linked with S.

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 Prior studies have shown that applications of the synthetic auxin 2,4‐dichlorophenoxyacetic acid (2,4‐D) to the foliage of potato plants can reduce common scab. Here field and glasshouse trials suggest that 2,4‐D foliar treatments may also reduce the biologically distinct tuber disease, powdery scab.

Soil biome variation of Lupinus nipomensis in wet‐cool vs. dry‐warm microhabitats and greenhouse
American Journal of Botany, Volume 112, Issue 4, April 2025.Abstract Premise Environmental DNA (eDNA) can be used to determine the composition of the soil biome community, revealing beneficial and antagonistic microbes and invertebrates associated with plants. eDNA analyses can complement traditional soil community studies, offering more comprehensive information for conservation practitioners. Studies are also

Quantification of root fungi using signature fatty acids [PDF]
, 2004 Both deleterious (pathogenic) and beneficial (mycorrhizal) fungi inhabit plant roots with strong impact on plant growth and health. Various methods have been used to quantify these fungi, such as indirect measurements of plant parameters, disease index ...
