FAQ
Frequently Asked Questions
Its use has declined in many regions due to environmental regulations and the development of newer herbicides, but it may still be used in specific contexts.
Like many herbicides, fenuron can be toxic if ingested in significant quantities and requires proper handling according to safety guidelines.
It is generally considered a non-selective herbicide, meaning it can damage or kill most plants it contacts, not just weeds.
It is usually applied as a spray to soil or foliage, where it is absorbed by plants and disrupts photosynthesis.
