Molecular genetic linkage map for allotetraploid colonial bentgrass
Interspecific hybridization is a widely used approach to improve crop species. We are pursuing the possibility of using interspecific hybridization between the turfgrass species colonial bentgrass (Agrostis capillaris L.) and creeping bentgrass (A. stolonifera L.) for the improvement of resistance to the fungal disease dollar spot (Sclerotinia homoeocarpa F.T. Bennett) in creeping bentgrass. From ...

Effects of Aspergillus niger in onion bulbs (Allium cepa L.) stored in the post–harvest phase
Onion bulbs were stored in the field, in piles until its commercialisation but the bulbs may be affected by fungal diseases. The objective was to assess the effects of the temperature (T), relative humidity (RH) within the piles, the water percentage (WP) and soluble solids (SS) of the bulbs over Aspergillus niger incidence. Bulbs of Cobriza INTA, Antártica INTA, Valcatorce INTA, Valuno ...

Metalexyl fungicide induced oxidative stress and apoptosis in mouse thymus: the effect of antox
Metalaxyl is a benzenoid fungicide used to control soil-borne fungal diseases on fruits, cotton, soybean, peanuts, ornamental and grasses. The present work aims to evaluate the effect of oxidative stress on the induction of apoptosis in thymocytes of mice by metalaxyl. The work extends to study the possible role played by antox in minimising the toxicity of metalaxyl. Thymus of metalexyl-treated ...

Validation of RAPD markers for white mold resistance in two snap bean populations based on field and greenhouse evaluations
White mold [Sclerotinia sclerotiorum (Lib.) de Bary] is a fungal disease that can reduce yield of beans (Phaseolus vulgaris L.). A recombinant inbred line population and an independent inbred backcross population were developed that share a common white mold resistant donor parent, G122. Both populations were evaluated for physiological resistance in the greenhouse using the oxalic acid test and ...

Effects of the boscalid fungicide Filan® on the marine amphipod Allorchestes compressa at environmentally relevant concentrations
Fungicides are widely used in agriculture to control fungal diseases. After application, fungicides can be transported offsite to surface and ground water and ultimately enter estuarine/marine environments. The presence of fungicides in the marine environment may pose risks to marine organisms but little is known about fungicide effects on these organisms, especially invertebrates. The present ...

Soil genotoxicity induced by successive applications of chlorothalonil under greenhouse conditions
Greenhouse production of vegetables has been developed rapidly in China. High temperature and humidity inside the greenhouse make this environment more suitable for fast reproduction of fungal diseases. Fungicides are among intensively used chemicals in the greenhouse to prevent crops from the invasive infection of phytopathogen, however, little is known about accumulation of fungicides in ...

Cultivar type, plant population, and ascochyta blight in chickpea
Integrated management strategies are required to minimize ascochyta blight, a fungal disease caused by Ascochyta rabiei (Pass.) Labrousse [teleomorph, Didymella rabiei (Kovachevski) v. Arx] in chickpea (Cicer arietinum L.). This study determined the effect of cultivars varying in plant architecture and plant population density (PPD) on the severity of ascochyta blight. Four desi chickpea (with ...

Interspecies transfer of resistance to anthracnose in lentil (Lens culinaris Medic.)
Lentil, Lens culinaris subsp. culinaris Medic., is an important legume crop on the Canadian prairies. Anthracnose, a fungal disease caused by Colletotrichum truncatum (Schwein.) Andrus & W.D. Moore, is a major barrier to seed yield and quality in lentil. Pathogenicity testing has revealed two races, Ct1 and Ct0, of C. truncatum in western Canada. No cultivar or landrace of cultivated lentil ...

Fungal diseases are on the rise. Is environmental change to blame?
Scientists and physicians are looking for clues to a worrying increase in fungal infections and exploring ways to reduce the threat. Fungi are everywhere — from the mushrooms that decompose fallen logs in the forest, to the mold that grows in your bathtub, to the microscopic fungal cells that reside naturally on your skin. Scientists estimate there are 1.5 million species of fungi on the ...

Genetic mapping of sheath blight resistance QTLS within tropical Japonica rice cultivars
Most commercial cultivars of rice (Oryza sativa L.) are susceptible to sheath blight (SB), a devastating fungal disease causing significant losses in grain yield and quality. There are limited sources of genetic resistance adapted to U.S. growing conditions, and no commercial long grain cultivar of rice is currently available in the United States with a high level of SB resistance. Sheath blight ...

Combat insect and crop disease after harvest
Maize harvest is particularly early this season. It also means early preparation to remove stalk stubble so insects like corn borers and leafrollers have no chance to leave everlasting damage to future crops. The Major Cyclone mower is designed for this purpose: to destroy the tough crop stubble. Conventional mulchers – including flails – quickly reach their limits in the fields and ...

Plastic-Puglia: Watering your crops while saving resources
In summer, keeping a vegetable garden well watered means keeping an open tap like you haven’t seen since your last kegger in college. When the little rainfall in winter can make it seem like summer year-round, our finite resource such as water becomes ever more precious, in spite of the few rainstorms that did pass through in winter. Since the last few years, world has become ...

Coir - The Ideal Growing Medium for Strawberries
In June 2015, newspapers around Britain were buzzing about an offer from Marks and Spencer which sought to revolutionize gardening and retail shopping. For the first time in history, UK shoppers were given the opportunity to pick their strawberries from the store itself. These strawberries, which are grown in baskets and under LED lights, added a new dimension to the definition of fresh. ...

Plants Activate `Wartime` Protein Production to Fight Invasion
Plants are constantly attacked by bacteria, viruses and other pathogens. When a plant senses a microbial invasion, fundamental changes occur in the chemical soup of proteins inside its cells, the workhorses of life. In a new study published in Cell, Duke University researchers have uncovered a key ingredient in plant cells that reprograms their protein-making machinery to fight disease. Crop ...

Chemical-free disinfection of seeds for maximum yield
Seeds are the starting point for the majority of our food. Vegetables, cereals, fruits and many, many more products start as small seeds. It is no surprise that the seed market has kept growing over the past few years. In fact, the seed market is projected to grow even more, with a CARG of 3,4% from 2017 to 2023. Safe and delicate disinfection of seeds is a must in order to produce a healthy and ...

Bananas Face Another Extinction Crisis, Can Gene Editing Save Bananas?
Bananas are one of the most popular fruits in the world, however, in fact bananas are at stake and we may no longer eat them at any time. And the source of this crisis is fungal infection, and in 1950, an outbreak of a banana infectious disease with fungal infection called "Panama disease" directly led to the complete extinction of Gros Michel, the most widely planted banana variety at that ...

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, ...

Spacers: How they have evolved and their role in efficient Drainage Systems for Hydroponic Agriculture (soil level and elevated gutter systems)
In 2014, Hydroponic Systems launched its first patented Spacer onto the market. Its main advantages include excellent aeration and elimination of the moisture accumulated between the substrates and the surfaces they rest on. Due to that, the Spacer quickly found expert grower’s approval. They appreciated that, when used, the Spacer avoided a number of issues and diseases across the ...
