Correct Answer:
Quackgrass has these characteristics
• Troublesome weed
especially in pastures and potato fields
• It cannot withstand the extreme high
temperatures of the southern United States
• A perennial that
can be a serious weed in home lawns and in row crops
• Can reproduce both
by seed and by very extensive rhizomes which may be 20 feet
or more in length
• These tough rhizomes are extremely
troublesome in potato fields because they will grow
right through a potato tuber thus destroying the marketable
portion of the crop
