LOOK FOR

Look for in shoots
• Collapse (sudden death) of one or more shoots on an arm or of the whole vine
• Broken, callused or damaged areas on trunk, cane or shoot
• Single affected vines or many along a row
• MAN OR THE VINE
• Yellowed or reddened leaves on isolated shoots or single arms
• Physical damage on shoot, arm or trunk below the affected leaves
• Tendrils, wires or training strings constricting the shoot, arm or rootling
  

   CONDITIONS

• MACHINERY
• Vineyard equipment sometimes hits and physically damages the vine which wilts or declines, particularly after hot weather.
• MAN OR THE VINE
• Sometimes caused by the things we do or by the vine itself.
