The Smarden incident and the arrival of Rachel Carson's Silent Spring in the UK lead people to a new view of the environment.
Fall armyworms have a number of characteristics that make them particularly hard to control. They are strong fliers, can breed at a high rate and also develop quick resistance to pesticides.
The Vespula germanica, or German wasp, is an invasive species in South Africa.

Indigenous biocontrol agents could be used to curb the spread of invasive wasps across South Africa and into sub-Saharan Africa.
Gardening in Australia requires, to varying degrees depending where in the country you are, pesticides, herbicides and fertilisers.
When working with garden chemicals, always make sure you are wearing gloves. Apply sprays and dusts downwind and wear goggles if necessary. Always follow the directions.
The threat of chemical weapon attacks is on the rise globally.
Governments often have limited knowledge of chemical production as it is the preserve of the private sector. Often these facilities are not as well secured as government facilities.
Honeybees aren’t the only wildlife affected by pesticides – wild bees and butterflies also feel the effect.

Two new studies have linked controversial pesticides neonicotinoides to wild bee and butterfly declines.

Advocates have argued for years about whether genetically engineered crops are safe to grow and eat. Plant pathologist and geneticist Pamela Ronald calls for a more nuanced discussion.
New research shows that street lighting changes the activity of moths, and is likely to disrupt nocturnal pollination.

Honey bees, which pollinate many valuable crops, are threatened by parasites, pesticides and development. But selective breeding, more benign pesticides and better nutrition could help turn the tide.
Are genetically engineered crops safe for human health and the environment? A new report says yes but points out problems and regulatory gaps. Three members of the study panel offer their takeaways.
Outbreaks of crown-of-thorns starfish, which eat coral, have been linked to poor water quality.

To fix pollution on the Great Barrier Reef, some farming practices will have to change.
Our modern crops need some help in the immunity department.

Modern agriculture is synonymous with monoculture. That lack of diversity is bad news for plants' natural immune defenses. Researchers are figuring out how to help plants fend off microbes – without pesticides.
Roundup, or the chemical glyphosate, is a very common herbicide used to kill weeds.
The World Health Organization classifies the common herbicide glyphosate as "probably carcinogenic to humans". But this doesn't mean using it to kill weeds in playgrounds will hurt children.
Pesticides have harmful effects on those using them.
Understanding the hazards and risks of pesticides is vital for people using them on crops.
Locust sits on a wheat stalk.
Insects have been in a feature in agriculture since the end of the 19th century. Using a combination of new and old control methods is the best way to deal with our food competitors.
Teeming with insect life?
Oregon Department of Agriculture
Continued use of pesticides will lower diversity of beneficial insects, costing corn farmers more money over time.
Not all bees are honeybees. This is a green ‘sweat’ bee.
Data from all over the globe suggest that bees are in decline, and we may lose a lot more than honey if bees are unable to cope with the changing climate and increasing demand for agricultural land.

Vaccines aren't just for animals anymore. Research shows priming plants with pathogen-derived compounds strengthens their immune systems and enhances protection against future attack.

Successive plans to curb the sediments, nutrients and pesticides flowing into the waters around the Great Barrier Reef have fallen short, leaving the corals that call the reef home highly vulnerable.
No insects here – and no insecticide either.
FAO of the UN
Spraying chemicals on crops has proven costly and counter-productive, according to new research.
