A recent study published in Nature Climate Change has suggested that the future global effects of climate change will impact the livelihoods of over 200,000 coastal farmers in Bangladesh as sea levels rise. Flooding of saltwater is already negatively impacting coastal residents in the country as soil conditions alter, causing farmers to either change from historic rice farming to aquaculture or to relocate further inland to avoid such salinity changes.
We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include the first report of Trochoideus desjardinsi in Cuba. 8 new records of Curculionidae in Saudi Arabia and 3 new species of aphids in China. Continue reading
Bacterial wilt (Ralstonia solanacearum) is one of the world’s most devastating plant diseases, with major crops such as tomato, potato and pepper being severely affected. Until now, crop breeders and farmers have had to simply wait for their crops to mature to determine the level of resistance to the disease. New research has shown that with modern metabolomics technology, it is possible to determine the level of disease resistance in plants much earlier at the seedling stage. This development could save both farmers and breeder time and money when growing host crops, and reduce the yield losses caused by the bacterial disease.
We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include the first report of sweet potato Badnavirus in South Africa. The first report of Arabis mosaic virus in rhubarb in Poland and the first report of maize yellow mosaic virus on corn in South Korea. Continue reading
Using specialised carbon-fixing material from blue-green algae, scientists have successfully engineered crop plants to boost photosynthetic productivity and crop yields. This exciting development promises to increase the yield of important food crops such as cassava, wheat and cowpea.

At the recent International Conference on Tropical Fruit Pest and Diseases (known as TROPED), which took place in Malaysia, attendees from countries including the Philippines, Fiji, China, Sudan, and India learned about Plantwise through a series of talks, demos, and an exhibition stand.
