For many low-income farmers, commercial pesticides are too costly to use. Seemingly, the next best option for many is to turn to homemade botanical insecticides using local sources. But how reliable are these resources, and are they safe to recommend?
A CABI-authored paper published in Agronomy for Sustainable Development reviews the efficacy of some of the most commonly used homemade botanicals in controlling insect pests. This paper specifically focuses on previous studies that tested homemade preparations under “realistic local field or storage conditions”, as there has been no previous in-depth review on this particular topic.
CABI programmes, Plantwise and Action on Invasives, have showcased their expertise in plant protection and improving rural livelihoods to a global audience of agriculture experts and scientists at the recent International Conference on Plant Protection in Horticulture held at ICAR-Indian Institute of Horticultural Research, Bengaluru.
Researchers at North Carolina State University have published an exciting study on a novel technology which allows farmers and extension workers to identify plant diseases remotely in the field using airborne chemical fingerprints. The newly developed handheld sensory device, which can be plugged into a smartphone, samples the airborne levels of volatile organic compounds (VOCs) that are released by plants from the leaves.
Between 2011 and 2015, CABI set up 22 Trichogrammarearing facilities as part of a project to promote the use of biologically-based Integrated Pest Management (IPM) for rice and maize crops. In addition to creating the Trichogramma rearing facilities, IPM strategies for rice and maize were developed in Southwestern China, Laos and Myanmar.
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 a report on the honey locust podgall midge (Dasineura gleditchiae) in Ireland, a report population fluctuations of fruit flies in guava orchards and a report on a new record of Helopeltis theivora pest on tropical pitcher plants.

Pests, which threaten to destroy key cash and food security crops including maize, tomato and beans, are to be prioritized as part of an integrated pest management strategy using state-of-the-art space-age technology.
Scores of smallholder farmers in Rwanda are the latest to benefit from the CABI-led consortium, funded by the UK Space Agency and the Global Challenges Research Fund with co-funding from the CABI-led Plantwise, that is using a combination of earth observation technology, satellite positioning and plant-pest lifecycle modelling to provide an evidence-based Pest Risk Information Service (PRISE).
Grassland habitats play an important ecological and economic role in Inner Mongolia, China. The primary threats to this ecosystem are grasshoppers and locusts, which are major pest insects across China. There are currently a range of monitoring and management strategies in place to control and reduce the damage caused by these pest species. However, successful reduction of these insect populations within the grassland habitats remains a national and regional challenge. Early identification of these pest species has been found to enable a more significant change of controlling the problem, with recent advances in technology opening several opportunities for developing this.
