Question

what are weeds ? How can we control them?​

Answer 1

$\huge{ \underline{ \underline \mathfrak \blue{Answer - }}}$

Weeds are unwanted and uncultivated plants that grow with crops and compete with crops for nutrients and can also cause crop toxification. Weeding is removal of weeds and is mostly done before flowering begins in crop plants. It is done using trowel, harrow or weedicides. Trowel is used in manual removal of weeds.

Answer 2

Answer:

Glyphosate is the most widely used weed killer in the world and is strong, safe & reliably eliminates most weeds in one application.

Kills right down to the roots so they don't grow back in one spray.

Kills 99% of garden weeds including tough ones like brambles & ivy.

Tilling before sowing of crops helps in the uprooting and killing of weeds. Which may dry up and get mixed with soil. Weeds are also controlled by using certain chemicals, called weedicides. Weedicides are sprayed in the fields to kill the weeds.
