Methods of Herbicides Application

A) Soil Application

Method	Description / Examples
Soil surface application	Application of herbicides on the soil surface; commonly used for most triazines, urea, and amide group herbicides.
Soil application	Incorporation of herbicides into soil; generally followed for aniline group herbicides such as fluchloralin.
Sub-surface application	Applied below the soil surface; mainly recommended for deep-rooted and perennial weeds.
Band application	Herbicides applied in bands over crop rows; commonly practiced in maize using atrazine.

B) Foliar Application

Method	Description
Blanket application	Uniform application of herbicides over the entire leaf surface; generally restricted to selective herbicides.
Direct application	Herbicides are sprayed directly on weeds present between crop rows, avoiding contact with crop plants.
Spot application	Herbicide solution is applied only on weed-infested patches in cropped or non-cropped fields, particularly for obnoxious weeds.
Basal application	Used for brushwood and unwanted trees; bark at the base of the stem up to about 30 cm height is removed, followed by a drenching spray of herbicide at the base.
