Herbicides that list control of night-flowering catchfly on the label are Ally Extra, dicamba, and Harmony or Express (thifensulfuron/tribenuron) premixes. The seedlings that White Cockle produces are light yellow in colour. Using IWM creates an opportunity to use herbicides more selectively, which reduces the impact on the environment as well as slow the development of weed resistance to herbicides. In Montana there are 19 Silene species, with about half of them being introduced from Europe, western Asia, or northern Africa. A widely distributed weedy species from Europe, White Campion is common in waste places and disturbed sites in both urban and rural areas.

In all four cases the weed control was executed using the same herbicide in the same doses and with regard to the weed species it showed the same level of efficiency. Common ragweed control was generally lower in Study 2 than Study 1 and may be due to greater ragweed populations in Study 2 trial locations. Mowing is best once flower buds begin to form and/or flowers begin to open. Also, its hairy leaves readily shed herbicide solution, making it difficult to apply adequate chemical concentrations. Consult herbicide labels for additional rate, application, and safety information. Digging up the entire plant is a practical way to eradicate small patches of a few species such as water-hemlock, but great care must be taken because of its high toxicity to humans.
