What are Herbicides
Herbicides, also commonly known as weedkillers, are substances used to control unwanted plants. Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact.
Advantage of Using Herbicides
- Herbicides can kill many weeds that survive by mimicry.
- Herbicides can be safely used where manual weeding damages the crop, e.g. onion, garlic, cumin etc.
- Herbicides are convenient to use on perennial and parasitic weeds where other methods are not effective.
