Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows.
Pests that have not been reported in a certain area are usually assumed to be absent, but analysis by the University of Exeter shows many pests are “currently unobserved, but probably present” (a likelihood of more than 75%).
The study identified large numbers of pests in this category in China, India, southern Brazil and some countries of the former USSR.
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.
A CABI-led project involving an international team of remote sensing and plant protection experts is helping China reduce its reliance on harmful pesticides to fight crop pests and diseases including yellow rust fungal disease of wheat and locusts.
The £1.6 million STFC Newton Agri-Tech Fund-financed project is leaving a lasting legacy in helping the Chinese Government reach its goal of zero increase in pesticide use by 2020 – adopting more sustainable controls, where possible, instead.
Every time you see a ladybug—also known as the ladybird beetle—you should tuck it in your wallet as a lucky charm to bring prosperity, according to the folklore of many countries. There’s a grain of truth in the old stories. Research shows that each ladybird in a cotton field in the North China Plain provides an economic benefit to farmers of at least 0.05 yuan, or one U.S. cent. This may not sound like much, but consider: Doubling the current ladybird density in two-thirds of Chinese cotton fields could bring farmers around $300 million per year.
CABI organized a five-day course on Integrated Pest Management (IPM) at the Graduate School of the Chinese Academy of Agricultural Science (CAAS) in Beijing on 13 to 17 February 2017. The course was delivered by CABI IPM expert Stefan Toepfer, a visiting professor at the Institute of Plant Protection in CAAS, where the joint Chinese Ministry of Agriculture-CABI laboratory is also located.
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 Alternaria leaf blight disease on oil palm in Thailand, caused by Alternaria longipes, the detection of a virus affecting chilli pepper in Chihuahua, Mexico and the association of Papaya leaf curl virus with the leaf curl disease of grain amaranth 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 new hosts (turmeric and black pepper) of root knot nematode in Pakistan, two fungal leaf spot pathogens on Indonesian cinnamon, and a species of phytoplasma not previously found on apple trees in China.
