2. AGENDA
Weeds present in non-cropped areas.
Consequences of spread of weeds in non-cropped
areas.
Management practices.
Brush weed management.
Soil treatments.
3. The areas where a crop or any intentionally planted
vegetation is not grown and that are in various uses
other than crops cultivation Non-cropped
area.
These non cropped areas generally refer to road sides,
airports, industrial areas, railroads, playground,
storage areas, public work yards, transmission lines,
banks of streams and rivers etc…
14. CONSEQUENCES OF SPREAD OF
WEEDS IN NON-CROPPED WEEDS
The fast growth and spread of these weeds prevent the
establishment of native trees, shrubs and grasses
Serious threat to plant biodiversity
Increased danger of reptiles to the inhabitants and
livestock .
Fodder scarcity.
Reduce the productivity of grasses.
15. Lantana camera and Ageratum plants when taken
along with other grasses or grazed accidentally cause
death to plants due to poisonous alkaloids.
Create fire hazards.
Reduce drainage.
Reduce visibility to snow blockage in roads.

30. BRUSH WEED MANAGEMENT
Brush weeds are shrubs or small trees.
Eg. Bushy growth of Lantana sp, Cassia sp, small trees of

33. 2.Trunk injections
I. Frill treatment
Herbicides are sprayed
entirely around the cut.
2,4 –D, 2,4 5-T can be
used.
34. II. Notching

axe for every 15 cm of
trunk circumference.
Cuts should be deep
enough and close to the
ground lines to place
herbicides.

The cuts may Sprout
immediately

vapours in the soil
Weed seeds get killed
