Plants for supporting Orius species
Orius laevigatus and Orius majusculus are predatory bugs, which are applied in several crops in greenhouses. They can eat many pests species, including nymphs and adults of thrips species, aphids, whtiteflies, eggs of moths, young caterpillars and spider mites. In some crops such as sweet pepper Orius survives easily. Cut roses are apparently less suitable for oviposition. For this reason we ...

Major breakthrough on how viruses infect plants
CSIRO plant scientists have shed light on a problem that has puzzled researchers since the first virus was discovered in 1892 – how exactly do they cause disease? In a major breakthrough that helps us better understand how viruses cause diseases in plants – and potentially in animals and humans – Dr Ming-Bo Wang and Neil Smith of CSIRO Plant Industry have revealed a ...

Controlled forest fires could kill invasive tree disease
In a new study, researchers examined the potential influence of human-driven changes in land-use on disease establishment in forests. The research suggests that changes in forest management, which encourage greater and more dense forest cover, are creating environmental conditions that promote disease. The invasive, fungal-like Phytophthora ramorum causes Sudden Oak Death (SOD), which is ...

Measures to prevent entry of citrus pests ‘are appropriate’
Existing measures are effective at protecting the EU from two serious diseases that attack citrus plants. That is the conclusion of risk assessments carried out by EFSA on Phyllosticta citricarpa, the organism which causes citrus black spot, and Xanthomonas citri, which causes citrus canker. Both pathogens present a risk to the EU citrus industry because host plants are present in Europe and the ...

Effect of afforestation on soil fungal community structure is greater than spatial distance
Afforestation is an important strategy to enhance terrestrial carbon sink. It alters regional landscapes and affects microbial processes in soil ecosystems. In particular, soil fungi, which play an important role in carbon and nitrogen cycling, could be greatly affected. However, at a watershed scale, the changes of soil fungal communities under afforestation could not only be influenced by host ...

EU study on bee-killing pesticides increases pressure for ban expansion
A study by the European Food Safety Authority (EFSA) has linked the spraying of three neonicotinoid pesticides to harmful effects on bees, increasing the pressure on the European Commission to expand a current EU-wide ban to all uses and crops, said Greenpeace. EFSA assessed the safety of pesticides thiamethoxam (produced by Syngenta), clothianidin and imidacloprid (both produced by Bayer) when ...

AgBiome Granted Multi-year Award to Discover Biological Solutions to Diseases Affecting Subsistence Crops of Sub-Saharan Africa
The Bill & Melinda Gates Foundation has awarded AgBiome a new multi-year grant, entitled “Broad-Spectrum Biological Control of Fungal Diseases,” which will fund the evaluation and development of lead, proprietary biological fungicides in the fields of African smallholder farmers. The aim of the project is to identify and validate biological fungicides to control one or more of ...

Florendovirus: new genus of virus in plant genomes
While the extent and importance of endogenous viral elements have been thoroughly researched in animals, there is a dearth of knowledge when it comes to plants. Within the framework of a broader international effort, researchers at INRA Versailles-Grignon and Cirad have described a new genus of the Caulimoviridae family of viruses, called Florendovirus, whose members have colonised the genomes of ...

Plants host pathogenic bacteria from livestock farming
Disease-causing bacteria resulting from livestock farming can contaminate food products and find their way to humans. This occurs remarkably effectively via plants, which explains why recent outbreaks due to infection with EHEC and other E. coli and Salmonella strains are regularly attributed to the consumption of fresh vegetables. These are the findings of researchers from Wageningen UR ...

Unearthing the Roots of Fungal Symbioses
To understand the bases of mutualistic symbiosis between soil mycorrhizal fungi and plants, an international consortium of researchers conducted the first broad, comparative phylogenomic analysis of mycorrhizal fungi. Scientists describe how the comparative analyses of 18 new fungal genomes allowed them to track the evolution of symbiotic fungi interacting with trees, heath plants and orchids. ...

Organic mulch lets insect pollinators do their job
As interest in organic agricultural and horticultural practices continues to grow, so does the need to identify alternative weed control practices. Mulching, a common practice used to control weeds and reduce the need for tillage, can also reduce insect pollinators' exposure to harmful pesticides; however, finding the right mulch materials that allow pollinators to flourish can be challenging. ...

Diversifying crops `could green African agriculture`
The biodiversity of crop fields could be key to a greener revolution in Africa, where ecosystems are degrading and crop yields are stagnating, says a study conducted in Malawi. African farmers could halve their fertiliser use and still get the same yields, the study found, with less year-to-year variation in yields and with as much as 70 per cent more protein in grains — by simply rotating ...

Desert bacteria could help boost crop yields
Desert soil microbes could help halt desertification and boost agriculture in arid regions of the Middle East and North Africa, according to a study. Scientists from the United Arab Emirates [UAE] have isolated local salt- and drought-tolerant strains of Rhizobia, soil bacteria that fix nitrogen when they become established inside the root nodules of legumes. Rhizobia bacteria establish a ...

Salt-tolerant wheat a breakthrough for better yields
Australian scientists have successfully carried out field trials of a salt-tolerant durum wheat, boosting grain yield by 25 per cent in salty soils. Durum is one of the most widely grown cereals in the world, but in saline soils it is vulnerable to salt build-up in the leaves, which can hinder growth and reduce yields, threatening food security. The researchers at the University of Adelaide and ...
