Crop Rotation
Crop rotation as an integrated mean to control weeds
• Crop rotation allows a better weed management,
because:
1 - Mechanical weeding is carried out in different
seasons and with different working depth.
2 - Chemical weed control is carried out with different
active ingredients and affects different weeds.
• As a result, weeds are not selected by resistance to certain herbicides or by crops, so formation of specialized weeds’ population is hindered.
• At the contrary absence of rotation (monocropping, monocolture) make easy the formation of specialized weeds population, which gets very difficult to manage. In certain cases, cropping had to be suspended for 1 or 2 years.
