The latest episode of the Tech4agri web series focuses on a number of farmers who attended Plantwise plant clinics in Trinidad and Tobago and received follow-up visits from Plantwise and NAMDEVCO extension workers.
As CABI’s Naitram Ramnanan explains: “We decided to follow up by visiting the farmer in the field and then realised that it was a pervasive problem in the christophene-growing areas of the country.” Plantwise is now working with a group of christophene [chayote] farmers around Brasso Seco to develop sustainable solutions to the pests and diseases affecting their crops.
Here’s a taste of some of the latest stories about plant health, including the invasive plants posing risk to food production in East Africa, a new tomato variety a hit with farmers in Australia and the use of botanical big data helping to predict how plant species will react to environmental change.

Scientists from the University of Delaware, USA, have recently uncovered critical information about the effect that deadly rice blast fungus has on rice plants, which could lead to more effective effective control measures in the fight against this disease. The team found that Magnaporthe grisea, the fungus responsible for rice blast, causes an increase in the production of abscisic acid in the plant on infection. Abscisic acid is a stress hormone usually released during times of drought to prevent the plant from losing water through holes in its leaves. However, it has been found that this hormone also causes a reduction in the disease fighting mechanisms of the plant.
The first factsheet of the month for 2016 ‘Blast in Paddy‘ contains information on the current methods of control used to manage rice blast in rice, or paddy as it is sometimes known. This Pest Management Decision guide was written by Mr G. Sudhakar from the M S Swaminathan Research Foundation (MSSRF), India.
