The weather is heating up and that has people planting, but a recent study has some worried about clearing their gardens of pesky weeds.
The study suggests a chemical found in common weed killers could lead to health issues like cancer, infertility and Parkinson's disease.
The chemical is called glyphosate and is found in herbicides like Round Up. The report recently published in the Scientific Journal of Entropy suggests left over residues of the commonly used herbicide could cause health issues.
A local expert said there's not enough evidence to support the claim.
"There's been literally 100's and 100's of studies done for under EPA conditions called good lab practices that say glyphosate is a perfectly safe product for human and animal health," said Bob Hammon Entomology and Agronomy expert, CSU Tri-River Extension.
Hammon said one of the best qualities of the herbicide is it's effectiveness in spot treatment.
"It doesn't run off easily because it binds to soil as soon as it touches soils particles, but if you put it on the soil or the weeds next to the crop it binds and it doesn't move and there's no carry over," said Hammon.
According to the Environmental Protection Agency studies conducted up to this point glyphosate is only effective on a plant metabolism and does not effect humans or animals.
The EPA is currently conducting a standard review of the chemical to be completed by 2015, to determine whether or not glyphosate should be limited.
