Kill it, these are nasty invasive plants. Triclopyr 4 is highly effective against this weed.

We saw a massive invasion of stinknet at the San Pascual Battlefield memorial site (not the State Park) Here are the coordinates for this massive infestation:  
It is where the three monuments are placed.

Thanks Robert. I relayed your data to the person who deals more closely with invasive plants in San Diego County.

Lots of stinkweed along the New River road between I -70 and AZ Hwy 74 beginning in early March 2020.

Dale is spot on as the weed is taking over the desert ground on the north side of Phoenix. There are numerous state sections that are covered in this toxic weed. I read it was not in the US until the 1980s and comes from South Africa. Unless you spray it in it's early stages with a Roundup-like (Glysophate) product it's tough to kill with the products typically used here for week control. Bigger plants can be pulled but it would be nice to get some moisture to help in that regard. I have not tried Triclopyr 4 but will. For sure I will be spraying with the pre-imergent like Pendulum to discourage its germination.
