What are the different types of herbicides?
Basically, there are two main types of herbicides – selective and non-selective. The former is used when inhibiting the growth of a specific weed, leaving the other plants unharmed. The non-selective variants kills all the plants it comes in contact with.
What are some selective herbicides?

Is Atrazine a selective herbicide?

What are selective herbicides?
Selective herbicides are a type of herbicide that will only kill a certain type of plant, while leaving other plants unaffected. This makes it useful when weeds are growing within or very closely to desirable plants or grass because you won’t have to worry about accidentally killing or harming your lawn or landscape plants.
What are contact herbicides and systemic herbicides?
They are known as Contact Herbicides and Systemic Herbicides. Contact herbicides: Contact is a word that means the chemical in that specific type of herbicide will kill the parts of the plant it contacts.
How do non-selective herbicides work?
Contact herbicides work best against annual plants, especially seedlings. If you want to remove perennial plants, keep in mind that contact herbicides can only provide top kill. The other kind of non-selective herbicide works in a systemic way. The chemicals enter through a point in the plant, usually the roots, and spread throughout.
What are the different types of weed control?
There are two broad types of weed control: selective and non-selective herbicides. Selective herbicides are used to remove one specific type of plant without harming the others, which is an effective way of managing weeds in crops or fields. Non-selective herbicides, on the other hand, kill all of the plants they come into contact with.
