Today, deism is considered to exist in the classical and modern forms, where the classical view takes what is called a cold approach by asserting the non-intervention of deity in the natural behavior of the created universe, while the modern deist formulation can be either warm (citing an involved deity) or cold (citing an uninvolved deity).
Herbicides are substances that are used for killing all types of plants, especially noxious weeds. Herbicides can be put into eight different groups including one group that is an ungrouped or, catch-all catagory.
Really a herbicide is a kind of pesticide. Cide means to kill, so a pesticide is just anything that's meant to kill a pest. So all of these are pesticides. So insecticides are meant to kill insects, fungicides are meant to kill fungi, herbicides are meant to kill plants.
