depends on what the background looks like, but if it’s fairly plain and you’ve got a fair bit of similar colour/pattern around then select area around the stick with either lasso or rectangular marque tool or similar. then select “patch tool”, drag the stick area away and it will replace it with whatever sample area you move it to.
sort of hard to explain, but experiment with the patch tool and you’ll work it out.
other than that, you can use the healing brush – press alt and click to set the sample area, then draw over the stick. again, experiment and you’ll see.
if you want to just put it on here i’ll do it for you!
