Question 1

Mechanical weed control in potatoes

False seedbed before planting (repeated, superficial tillage to destroy seedlings and stimulate germination of weed seeds

Shallow ridges on planting

possibly blind harrowing (slight cultivation of ridges)

Ridge build up

harrowing

formation of the ridges shortly before row closure

Question 2

Objectives of leave removal

Answer 2

Shell strength

limit tuber size

prevent viral infection of the tubers at seed potatoes (spraying time for seed potatoes depends on the aphid infestation)

reduce tuber rot

faciliate harvesting

delay late weeding

Question 3

How can leaves be removed?

Answer 3

With herbicides

Mechnanical herb removal with special machines helps to reduce herbicide use, but increases the risk of weeding

thermal herb removal

combination of several measures

Question 4

New cultivation system ‘All in one’
