- For control purposes there are two types of thistleâ€”Californians and the rest
- Annual and biennial thistles are best controlled by pasture management practices that encourage the maintenance of a tight sward
- Topping, grubbing and herbicides also have a place in thistle control
- Californian thistle can be controlled by regular rotational grazing, associated with the use of either topping or herbicides to deplete root reserves and weaken the plant.
