The Bill and Melinda Gates Foundation has paired with the UK Government to award the Next Generation (NextGen) Cassava Breeding Project $35 million with the aim of promoting the growth of cassava crops and to improve food security in Sub-Saharan Africa.
Globally, battery manufacturing and recycling plants have been identified as the major sources of soil lead contamination that have resulted in lead exposure to neighbouring communities via the accumulation of lead within plants.
Lead is naturally found in soil in relatively low concentrations (10-50 mg/kg) in which it is taken up by plants via the roots and accumulates within root cells as lead is used in low levels by plants. Excessive lead concentrations found within plants have been shown to reduce the functionality of morphological, biochemical and physiological functions as well as promoting deleterious effects. For more detailed information on the effects of lead on plant health, see here.
“No matter where you’re from, your dreams are valid!” Passionate words spoken in 2014 during an indelible Oscar moment. The utterance of these words, coupled with the winning of an Academy Award, announced Lupita Nyong’o’s entry into the global stage. Two years later in Lupita’s country of origin, Kenya, long-held dreams in the plant health sector are realized.
Indeed, the journey to realizing the usefulness of mobile technologies for the plant health sector has been long, and to some extent treacherous. Was the Plantwise program setting up the agricultural extension officers for failure? Was the program having unrealistic expectations? Could it be, in the program’s quest to keep up with the times, it was essentially building an ivory tower? All these were questions Plantwise grappled with in 2014 when it introduced mobile technologies for the running of plant clinics.
Cabbage is an important crop in Ghana where it grows all year round, right across the country. It is mainly grown for commercial production in Southern Ghana, in Akwapim and Kwahu areas and in the moist high elevations around Tarkwa.
Growing cabbage in Ghana is challenging since it can be attacked by a variety of pests, such as cabbage aphids, caterpillars, cabbage webworm, diamondback moth, mole cricket, snails and rodents. Worldwide, aphids are a major concern because they commonly spread plant-infecting viruses. These are often diagnosed as turnip mosaic virus and cauliflower mosaic virus, particularly in Europe and the US, according to Dr John Carr, University of Cambridge, UK (Phys.org, 2017).
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 new host records for the fruit fly Ceratitis capitata in the state of Pará, Brazil, the presence of Meloidogyne enterolobii on Jalapeño pepper in Sinaloa, Mexico and the first report of the invasive mealybug Phenacoccus parvus infesting Naga King chili in India.
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 powdery mildew (Erysiphe quercicola) on rubber trees in Viet Nam, the occurrence of anthracnose fruit rot (Colletotrichum nymphaeae) on pepper in Malaysia and the characterization of a novel polerovirus infecting maize in China.
Here’s a taste of some of the latest stories about plant health, including the effects of Tuta absoluta on tomato prices in Zambia, hail causing damage to crops in Colombia and the threat of invasive species on agriculture around the world.
