Control of weeds, pests and diseases by cultural methods

Question 1

Cultural methods description

Answer 1

non-chemical methods of preventing problem organisms from establishing and affecting the crop.
These methods often require planning and aren’t reactive.

Question 2

Ploughing

Answer 2

A top layer of soil is turned over to bury perennial weeds (which then die and decompose).

Question 3

Removal of weeds

Answer 3

Weeds are removed early in the life of the crop, enabling the crop plant to gain a head start and be better able to out- compete weeds at a later point.

A very different crop is grown in a field in successive years. This prevents the build up of pathogens which may cause an outbreak if the same crop is grown year after year in the same field.
