How to grow herbs without using pesticides
- by admin
Gardeners have been experimenting with growing herbs without pesticides for decades, but new research suggests the plants have also been affected by the herbicides glyphosate and dicamba.
A new study by a University of Arizona team suggests the use of herbicides can be problematic, with some plants becoming sick and dying.
The herbicides have been blamed for the demise of many native species, including the red sage, but now researchers say they’re also having a negative impact on the species that live in the fields.
The study was published online by the journal PLOS ONE.
The researchers found some plants were dying and some had trouble growing without pesticides.
“These findings provide a possible link between glyphosate and herbicide use and the development of disease,” said study author Matthew H. Kuehn, an assistant professor of agronomy at the UA School of Forestry and Environmental Studies.
“The ability of plants to recover after a prolonged exposure to glyphosate can be critical for maintaining their resilience to stress and disease.
This may have implications for herbicide management in the future.”
The researchers also say they think herbicides may have a negative effect on the plants’ ability to withstand the effects of climate change.
The paper was published in the Proceedings of the National Academy of Sciences.
It’s not clear how the plants got sick.
Kueshne said he’s not aware of any cases of the herbicide causing cancer, but that it is possible it could cause other diseases.
The new research was conducted in a field near Tucson, Ariz., in a growing population of red sage and other herbaceous plants.
Researchers planted a number of herbaceous crops in the field, some of which had been sprayed with glyphosate, and then the plants were collected.
Katesh said that, in some cases, the herb plants started to die or had trouble surviving the effects.
In other cases, there were no signs of damage to the plants, Kueshn said.
“There was no evidence that there were other problems with the crops or other problems in the soil or in the air,” Kueshs said.
Kühn said he and his team were trying to identify the effects the herb treatments had on the herbs.
He said they were particularly interested in the ability of the plants to tolerate the chemicals and were able to test them on the herb crops.
The findings show that there is a range of potential health effects, from herbicide resistance to altered growth rates.
“We’re not aware that there’s any significant difference in survival between herbicide-treated and control-treated plants, and we’re also not aware there’s a significant difference between herbicides that have been used in a controlled manner and those that haven’t,” Kuehs said in a press release.
The plants used in the study were herbaceous and fern, as well as a number other herb plants, including oak, cedar and white oak.
Kutesh said the researchers plan to continue their research into the health effects of herbicide exposure in the coming months.
