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.
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.
Simon N. Groot, the Dutch founder of East-West Seed, has won the World Food Prize 2019 for empowering millions of smallholder farmers in more than 60 countries earn greater incomes through enhanced vegetable production.
New research by CABI reveals that just five invasive alien species are causing US$0.9 – 1.1 billion in economic losses to smallholder farmers across six eastern African countries each year, equating to 1.8% – 2.2% of total agricultural GDP for the region. These losses are expected to grow to $1.0 – 1.2 billion per year over the next 5-10 years, highlighting the urgent need for coordinated responses at regional, national and international levels.
New research published in the open-access journal Global Food Security estimates the alarming level of economic losses suffered by smallholder farmers each year in eastern Africa, to a handful of species that have become damaging crop pests since their introduction to the region. These few invasive species can have devastating impacts on important staples such as maize, but also high-value crops including tomatoes, peas and green beans.
CABI has just launched its Facebook page. In addition to posts from Plantwise, there will be news and articles from the other arms of CABI including Global Health, Environmental Impact, Animal Science, Forest Science, and newly published books and journals. There will also be updates from the work that CABI is doing in countries all over the world from Barbados to Bangladesh.
If you are interested in invasive species, international development or climate change, we highly recommend that you ‘like’ the CABI Facebook page to stay up-to-date with the latest research and activities in the field.
