I think it is fertilizer or something !!

Answer 2

A herbicide is a pesticide used to kill unwanted plants.

Selective herbicides kill certain targets while leaving the desired crop relatively unharmed.

Some of these act by interfering with the growth of the weed and are often based on plant hormones.

Herbicides used to clear waste ground are nonselective and kill all plant material with which they come into contact.

Some plants produce natural herbicides, such as the genus Juglans (walnuts).
