disease controlled » disease:a controlled (Expand search), disease controlling (Expand search), disease control (Expand search)
decrease spot » decrease sod (Expand search), decrease soon (Expand search), decrease of (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease spot disease controlled processes ) OR ( python code to python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease spot disease controlled processes ) OR ( python code to python programming ))*.
