A Cornell University-led team of researchers field-tested 14 active ingredients in insecticides, applied in a variety of methods, to understand the best treatment options against the Allium leafminer, a growing threat to onions, garlic and leeks.
This week, scientists of the Institute of Bee Health of the University of Bern have published an article in the peer-reviewed journal Communications Biology, which shows how even low doses of neonicotinoid insecticides, as they may realistically occur in contaminated soils, adversely affect the development of black garden ants (Lasius niger). This study highlights the need to overthink current deployment and management of chemical pest control for more sustainable agriculture.
Precision agriculture technologies can improve efficiency on smaller farms
The decline of the Western bumblebee is likely not limited to one culprit but, instead, due to several factors that interact such as pesticides, pathogens, climate change and habitat loss.
Purdue researchers have figured out a way to calculate surface viscosity just by looking at a stretched droplet as it starts to break.
DNA clues show that eelgrass growing underwater along Washington state shorelines is associated with fewer of the single-celled algae that produce harmful toxins in shellfish. Observations show this effect extends 45 feet beyond the edge of the eelgrass bed.
Fish exposed to very low levels of chemicals commonly found in waterways can pass the impacts on to future generations that were never directly exposed to the chemicals, according to Oregon State University researchers.
The tool allows for effectively calculating fertigation with reclaimed water, a technique that applies nutrients to crops by means of the irrigation system.
The world is very aware of the overuse of antibiotics and the development of resistance in bacterial populations. This has led to calls for greater control and monitoring of their use in both human and veterinary medicine. What is less well known is that antibiotics, are routinely used in crop production and according to new research are being recommended far more frequently and on a much greater variety of crops than previously thought.
Cabbage plants defend themselves against herbivores and pathogens by deploying a defensive mechanism called the mustard oil bomb. Researchers at the Max Planck Institute for Chemical Ecology and the University of Pretoria have now been able to show that this defense is also effective against the widespread fungus Sclerotinia sclerotiorum. However, the pathogen uses at least two different detoxification mechanisms that enable the fungus to successfully spread on plants defended in this way.
