We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this month include the first report of a novel alphapartitivirus in Rhizoctonia oryzae-sativae, the causal agent of aggregate sheath spot disease of rice; a report on Bursaphelenchus rockyi sp. in peat moss in Russia and a report on Bursaphelenchus michalskii n. on large elm bark beetles and its association with Dutch elm disease.

Scientists and crop breeders in China have produced new varieties of rice called ‘Green Super Rice’ (GSR) to help tackle the global burden of increasing populations, food production and farmer incomes with its 20% increase in yield across varying challenging growing conditions.
Bananas are eaten the world over but could they really become extinct if a strain of Panama disease takes hold?
Did you know that more than 100 billion bananas are eaten every year in the world, making them the fourth most popular agricultural product? You might also be surprised to learn that Uganda has the highest average per capita consumption in the world, where residents eat an average of 226kgs of bananas per person per year.
In short, bananas are big business – a $35billion global industry as a rough estimate. But all that could come to a crashing halt if the headline in the British Daily Mail newspaper, predicting the fruit’s extinction, is to be believed. The fears are that a strain of Panama disease could wipe out the humble banana putting the food security of millions in Developing World countries that depend upon it for nutrition at risk.

In a recently published paper in Scientific African, CABI’s Willis Ochilo led on a study which captured a better understanding of tomato producers in Kenya, describing in detail the production practices in order to identify challenges and opportunities for increasing tomato productivity for the country’s smallholder communities.
Tomato is a good source of vitamins A and C, and lycopene making it an important crop in terms of food and nutritional security for families in Kenya, and is in fact eaten in nearly all households across the country.

In an unprecedented study, honey bees have been found to be the world’s most important single species pollinator in natural ecosystems. Working alongside wild bees, they are also said to be responsible for every one in three bites of food. For the smallholder farmer, befriending bees – both honey and wild – could mean more efficient, high quality pollination of crops, as well as pollinating wild plants for cattle and other livestock to graze on. The sale of honey could also provide a vital additional source of income. But the bees need human help in return; the global bee population is in decline due to the use of harmful pesticides, climate change and habitat loss. Finding a productive partnership between these small creatures and smallholders could benefit both sides. Continue reading
Invasive alien species (IAS) have devastating impacts on native biota, causing the decline or even extinction of native species, negatively affecting ecosystems. Invasive plants, animals, insects and microorganisms enter and establish in environments outside of their natural habitat. They reproduce rapidly, out-compete native species for food, water and space, and are one of the main causes of global biodiversity loss. Species can be introduced deliberately, through for example, fish farming, pet trade, horticulture, bio-control or unintentionally, through such means as land and water transportation, travel, and scientific research.
CABI, under its Action on Invasives programme, is working to manage the already existing and potential invasive species in Pakistan. Pest Management Decision Guides (PMDGs), through the Plantwise Knowledge Bank are practical, step-by-step tools for plant doctors and extension agents to give advice following the principles of integrated pest management (IPM).
