Question 2 of 3
2. Question
There are three main techniques used to prevent viable seed development. List these in order of most desirable to least desirable by dragging and dropping the boxes.
-
Cutting in the early phase of maturity so that the seed will not form adequately and there is insufficient time for the materials in the cut plant to translocate to the seed before the plant dries out.
-
Use herbicides (glyphosate or paraquat) at rates to sterilise the seed while it is forming, followed by cutting after the withholding period is observed (usually two days).
-
Disrupt the maturing process of the seed by depriving it of water, nutrients or oxygen through the conservation process (such as cutting it).
