Some of the problem dicotyledonous weeds, such as common lambsquarters (Chenopodium album), pigweed (Amaranthus retroflexus) and Russian thistle (Salsola kali), are resistant to asulam. On the other hand, as a postemergence herbicide asulam is effective against Rumex spp., Averui fatua and Pteridium aquilinum. 

With very few exceptions, naturally occurring acids and alkalies are weak. All acids known in antiquity were of organic origin some occur in fruits, especially in unripe fruitjuices. Most ancient alkalies were derived from the ash of plants such as barilla, Salsola soda and Salsola kali (Russian thistle), and kelp.
