A wide variety of herbicides, such as 2,4-D, PastureGard, and Crossbow have proven effective in controlling common cocklebur. Treatment should be applied between May and July. However these chemicals should not be sprayed near a garden as it can be harmful to the plants and/or person consuming the vegetables/fruit.
Timely mowing can reduce the top growth and seed production of common cocklebur. This is best achieved when the plants are around 12 inches tall and they are cut down to 4 inches or less. Digging out the weeds, including the root system, may also be an option in the garden setting.

Hope this is helpful!
