Weed Control in Forest and Grassland

To know the control of specific weeds observed in non-cropped areas.

I) Weeds of Forest: Woody Plant Species:

Control:

1. Cutting
2. Burning
3. Bulldozing
4. Use of rollers
5. Mowers discs
6. Chemicals
7. Managed grazing
8. Insects etc.

Ester formations of 2.4-D are most effective to control woody species. Other herbicides effective are (i) Formations of 2.4,5-T, 2.4-DB, MCPB and Silvex (ii) Amitrol (iii) Ammate (iv) Fenuran pallets.

II) Weeds in Grass Lands:

Shrubby and herbaceous weeds grow in grass land. There weeds are competitive and harmful to grass growth due to mismanagement of grassland.

Control:

a. Controlled and deformed grazing.

b. Proper fertilization.

c. Appropriate gap filling.

d. Soil and water conservation etc. are used to keep the weeds suppressed.

Physical Weed Control in Grasslands:

Burning, mowing, hand grazing controlled grasing grubling etc.

Biological Weed Control:

In grassland prickly pear (Opunting spp) in Australia has been successfully controlled.

Herbicidal Control in Grasslands:

a. Removal of weeds from grasslands and

b. Remove them to grow more nutritive species that are present.

c. Herbicides control weeds efficiently non – residual herbicides like paraquat and MSMA are successfully use to kill total vegetation and to plant seeds of desired grasses and legumes.
