If you read some sicklepod information, you will find that this is one interesting plant. Look for a stalk up to 2 ½ feet (0.75 m.) high, smooth, hairless, oval leaves and showy, buttercup-yellow flowers with five petals each.

Sicklepods are annuals that bloom for one to two months, from late summer into fall. However, the plants reseed themselves so generously that they are considered sicklepod weeds, and are hard to eradicate. A tough plant, sicklepod grows in most soils, including the poor, compressed earth between railroad ties.
Sicklepods are also drought tolerant and disease resistant. These qualities, together with its impressive seed quantities, make controlling sicklepod difficult.
Sicklepod is also a bad thing to have growing in a pasture since it is toxic. Hay taken from pastures with sicklepod weed in them is of no use for livestock since they refuse to eat the contaminated hay.
People faced with these problems are interested in sicklepod control. They want to know how to get rid of sicklepod plants.

Sicklepod control is not as difficult as controlling some other weeds. You can remove sickleweed manually by pulling it up by the roots as long as you are sure to pull out the entire taproot.
Alternatively, eradicate sickleweed by applying post-emergent herbicides.
