A new risk model developed by researchers at the University of Delaware allows lima bean growers to assess their fields' risk of downy mildew, a fungal-like disease. The tool provides a numeric scale from 1 to 10 and takes into account individual tolerance levels.
A study found that multiple pesticides within colonies closely correlate with colony death, including some 'bee-safe' fungicides. The researchers assessed 91 colonies and found that the number of different compounds was highly predictive of colony death.
Researchers found chemicals in commonly used fungicides alter gene expression in mouse brain cells similar to those in people with autism and Alzheimer's disease. The study suggests these chemicals may impact brain function, including synaptic transmission and inflammation.
A new Cornell study reveals that pesticides harm wild bees and indirectly threaten native pollinators, particularly in orchards with limited natural areas. The research highlights the importance of protecting these vital pollinators for food production, as they contribute to 35% of global food production.
Researchers at the University of Exeter have discovered a long-distance messaging system in fungi that enables them to evade plant immune systems. By targeting this process, new fungicides could be developed to prevent crop damage and reduce losses estimated at $60 billion annually.
Research found Aspergillus fungus resistant to life-saving drugs in UK rural areas treated with fungicides. The study highlights a worrying link between fungicide use and the emergence of multi-resistant fungal strains posing a significant threat to transplant patients and those with weakened immune systems.
Scientists have confirmed the presence of a new fungus variant in Alava, Spain, which may be more resistant to conventional fungicides. This discovery could lead to the emergence of more aggressive strains of Phytophthora infestans, causing further damage to potato crops.
Researchers have found pesticides commonly used in California's agricultural regions contaminating Pacific Tree Frogs in remote mountain areas, including national parks. The detection of pyraclostrobin, tebuconazole, and simazine highlights the potential long-term impact on biodiversity.
A Clemson University researcher is working on a project to develop a model that can predict the risk of downy mildew infection in cucurbit crops. This model aims to help reduce the need for fungicides, lower production costs, and increase crop yields.
A Purdue University study found that four popular fungicides have lost effectiveness against apple scab in Indiana and Michigan. The fungus has developed resistance, making it difficult for growers to manage their orchards without using older, more expensive fungicides.
A recent study published in Phytopathology reveals that fungicide applications on corn are unlikely to produce yield increases unless fungal diseases are present. Farmers should weigh the cost of treatments against potential benefits and consider the price of corn when making decisions.
University of Illinois researchers tested foliar fungicides on hail-damaged corn and found no significant improvement in yield. The study simulated hail damage to corn and applied fungicides, but results showed no differential reaction where the fungicide improved damaged corn.
A Purdue University study found that planting more corn for biofuels would lead to higher levels of nitrogen, fungicides, and phosphorus in nearby water sources. Continuous-corn rotations result in greater sediment losses, allowing these pollutants to enter the water.
Researchers developed new 'paldoxins' that block fungal enzymes, boosting plants' natural defenses and overcoming fungal attacks. These environmentally friendly fungicides could protect crops like corn, wheat, and soybeans from disease-causing fungi.
Researchers found that combining pesticides disrupts frog development, causing delayed maturation, retarded growth, and increased susceptibility to infections. The study suggests that the interaction between pesticides and environmental factors may be a major contributor to amphibian decline.
New research by Purdue University finds that fungicides on golf courses do not contaminate surface water or groundwater when used according to manufacturer's guidelines. In fact, most of the fungicide remains on the grass leaf blade and is degraded internally.
