Ragged, cracked leaves, are often seen, as are swollen stems at ground level or near the ground, or the formation of 3 to 4 stalks on the same plant. Seedlings may be cut off at the base. The maggots reach body lengths of up to 5 mm. Approximately 30 days after hatching from the eggs, the maggots have completed their development and they leave the host plants a... | | |
