Question

Write the methods employed to control weeds.

Answer 1

Hey Mate..!!!

Pls find the answer below:

The methods employed for weed control are as follows:

♦ Mechanical Method: The weed plants are removed from the field either manually or with the help of agricultural implements like uprooting or hand hoeing or weeding with khurpi, ploughing, etc.

♦ Cultural Method: This method includes:

• Proper seed bed preparation
• Timely sowing of crops
• Intercropping
• Crop rotation

♦ Chemical Methods: By Spraying chemicals that do not harm crop plants but destroy only the weed plants, the latter can be controlled. These chemicals are called weeclicides, e.g., 2, 4-D and atrazine.

♦ Biological Method: As we know, some insects feed an particular weeds. Thus, we use these insects as biological weed-controlling agents like the use of cochineal insect to control Opuntia weed and the use of the grass carp fish to control aquatic weeds.
