This paper finds that neonicotinoid use in rice paddies surrounding Lake Shinji in Japan was followed by a collapse in the fishery yields of smelt and eel, likely due to neonicotinoids reducing the abundance of zooplankton on which smelt and eels feed. The paper suggests that similar fishery yields decreases in lake across Japan could be linked to neonicotinoid use.

This report, commissioned by the Wildlife Trusts (a group of UK charities), summarises existing evidence on declines in insects, many types of which have substantially decreased in abundance since 1970 (see for example Worldwide decline of the entomofauna: A review of its drivers). It also explores the drivers of these declines and calls for an urgent halt to “all routine and unnecessary use of pesticides”.

The initial results of an experiment on palm oil plantations in Sumatra, Indonesia, suggests that using less fertiliser on palm oil plantations and controlling weeds through mechanical weeding instead of herbicide use could be beneficial both ecologically and economically.

According to this report from UK charity the Pesticide Action Network and the Soil Association, mixtures of pesticides can be more harmful to human health than the sum of the toxicity of the individual pesticides would suggest. 

This feature in the New Food Economy explores how autonomous weed-picking robots could replace herbicides and tackle weeds that have become resistant to some herbicides. The robots use both GPS tracking and cameras to navigate fields and remove weeds.

This report by the US non-profit Environmental Working Group analyses pesticide residue data from the US Department of Agriculture. It concludes that around 70% of produce in the US is sold with pesticide residues, with particularly high levels in strawberries, spinach and kale and relatively low levels in avocados, sweetcorn and pineapples.

Over 40% of insect species are at risk of extinction over the next few decades and 75% to 98% of insect biomass has already been lost, according to this review of the current state of knowledge about insect declines, with habitat loss through conversion to intensive agriculture being the main driver. Agro-chemical pollutants, invasive species and climate change are also driving insect declines.

This book discusses options for sustainable weed control for a variety of crops. Topics covered include the impacts of herbicides on people, soils and ecosystems, integrated weed management, and herbicide resistance.

Switching to an organic diet for six days significantly reduced the levels of several pesticides and pesticide metabolites found in the urine of the 16 participants of this study.
