Why are certain herbicides banned?
Herbicides, also known as weedkillers, are chemical substances used to control and kill unwanted plants (weeds), leaving the desired plants unharmed. While these products are very useful for farmers, they are not always safe. In fact, many herbicides that were in common use around the world a few years ago are slowly being banned. In this blog post, we will look at a few herbicides that are used ...

The influence of reduced light intensity on the response of benthic diatoms to herbicide exposure
Herbicide pollution events in aquatic ecosystems often co‐occur with increased turbidity and reduced light intensity. It is therefore important to determine whether reduced light intensity can influence herbicide toxicity, especially to primary producers such as benthic diatoms. Benthic diatoms collected from four rivers were exposed to herbicides in 48 h rapid toxicity tests under high light ...

Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...

The complex nature of GMOs calls for a new conversation
An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many domesticated ...
