Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...

Detecting plant root diseases & pests
Soil-borne pests and diseases are harder to detect than those on the aerial parts of a plant. Visible symptoms in leaves and stem appear only in the final stages of the attacks. If plants are treated at this point, it may be difficult to avoid plant injury, as plants could already have been severely impacted. Early detection and identification are key to prevent crop loss. There are, however, ...

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 ...

The developing world is awash in pesticides. Does it have to be?
Herbicides, insecticides and fungicides threaten the environment and human health in many parts of the world. But research is pointing to a better approach. In today’s globalized world, it is not inconceivable that one might drink coffee from Colombia in the morning, munch cashews from Vietnam for lunch and gobble grains from Ethiopia for dinner. That we can enjoy these products is thanks, ...

Case study - Back Sand Point
As part of the £3.5 million hazardous landfill restoration project at involving 250,000 tonnes of restoration material we were contracted by local firm KLR to hydroseed over 100,000m2 in two stages using an Emorsgate wildflower seed mixture. In addition to the hydroseeding works, we also planted over 6,000 bare root trees and shrubs across the site, helping transform the once blighted land ...

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, ...

Chemical and ecological control methods for Epitrix spp.
Very little information exists in regards to the control options available for potato flea beetles, Epitrix spp. This short review covers both chemical and ecological options currently available for control of Epitrix spp. Synthetic pyrethroids are the weapon of choice for the beetles. However, the impetus in integrated pest management is to do timely (early-season) applications with something ...

The Spirit Level, economic democracy and health inequalities
'The Spirit Level' by Wilkinson and Pickett (2009) provides a serious critique of inequality and how it blights the lives of many people in high-income countries. Unfolding in two main sections, this paper initially outlines Wilkinson's thesis generally before focusing and initiating a debate on Wilkinson and Pickett's suggestion of economic democracy (increased employee control and ...

Characterization of resistance to fusarium head blight in an eastern U.S. soft red winter wheat population
Host resistance is important to control Fusarium head blight (FHB) ), caused by the fungus Fusarium graminearum (Schwabe) [teleomorph: Gibberella zeae (schw.) Petch], in wheat (Triticum aestivum L.). Effective breeding requires understanding the genetics of resistance in breeding populations. Our objective was to deduce the genetics of FHB resistance in eastern U.S. soft red winter wheat (SRWW) ...

Effects of planting pattern and fungicide application systems on ascochyta blight control and seed yield in chickpea
Improved cultural practices can be used to manage ascochyta blight in chickpea (Cicer arietinum L.), a disease caused by Ascochyta rabiei (Pass.) Labrousse. This study examined the effect of planting pattern, seeding rate, and fungicide application systems on ascochyta blight severity and crop yield of chickpea at Swift Current (50°25' N, 107° 44' W), SK, Canada, in 2004 and 2005. Crop was grown ...

Ancestral landraces of common bean from the South of Europe and their agronomical value for breeding programs
Selection among breeding lines has been widely used to identify important cultivars and favorable alleles for adaptation, and resistance to abiotic and biotic stress. The objective of this work was to study the variability among common bean breeding lines selected from ancestral landraces, to evaluate the reaction of these lines to anthracnose (ANT) rust, common bacterial blight (CBB), halo ...

Meta-analysis of QTL associated with fusarium head blight resistance in wheat
Quantitative trait loci (QTL) associated with resistance to Fusarium head blight (FHB), which is mainly caused by Fusarium graminearum Schwabe [telomorph: Gibberella zeae Schw. (Petch)], have been identified in wheat (Triticum aestivum L.) from different countries. Due to the differences of genetic backgrounds and analysis methods, the linked marker and significance levels of QTL are not ...

Tests of taxonomic and biogeographic predictivity: Resistance to disease and insect pests in wild relatives of cultivated potato
A major justification for taxonomic and biogeographic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in only a representative subset of the group. Such predictors are regularly used by breeders interested in choosing potential sources of disease and pest resistant germplasm for cultivar improvement, by genebank managers to ...
