Question

which of these is the primary drawback of digging up individual plants as part of a control solution for a small infestation that needs to be cleared quickly?
a. it could result in chemical contamination of the soil
b. it would remove only seedlings
c. it would take much longer than other control methods would
d. it could leave behind seeds that might germinate again and regrow in a new infestation

Explanation:

Digging up individual plants may not remove all seeds. Seeds left in the soil can germinate and cause a new infestation, which is a significant drawback when trying to quickly clear an infestation. Chemical contamination is not relevant here as it's just digging. It doesn't only remove seedlings and isn't necessarily slower than other methods in all cases.

Answer:

D. It could leave behind seeds that might germinate again and regrow in a new infestation
