I plant a quarter-acre of zinnias, but I have a serious problem with pigweed and lamb's quarter. I am looking for a pre-emergent that might work over the zinnia seeds while preventing the pigweed and lamb's quarter from growing.
Pendulum 3.3 EC will prevent lambsquarter and pigweed from germinating. Zinnia is not listed on the product label so we would not suggest using the product in the newly seeded areas.
