Should I trim this diseased frond?

[Noob2palms]

Hi I have this potted bottle palm it has 5 fronds in total 2 are very advanced with leaf spot disease. Should I remove one or two of them to avoid spread even though it’s still green. The most advanced one is the next frond to die so it would just speed up that process. I did copper fungicide spray on the others to help avoid spread but it looks like all have at least a little bit. It’s rained a lot here and I think that’s contributed too 
thanks 

pic 1 and 2 are the front frond I think I should remove - pic 3 is a back frond that’s next most advanced and 4 is whole tree

Don't cut off any fronds unless they are completely brown - the palm takes back all the nutrients to use for growth. And as you are in NY yours needs to conserve as many nutrients as possible. If the appearance of the fronds really bothers you, take a pair of sharp scissors and trim away the brown tips.

Thanks I appreciate the reply! The appearance doesn’t bother me I just want to make sure I’m not sure I’m not enabling it to spread

I don't think the fronds are diseased, just showing wear and tear - a combination of dry tipping, sunburn, windburn. The oldest frond is probably being recycled before being shed. The other frond is the 2nd oldest and will be next. The newest fronds look good. All in all, a very nice bottle grown in NY. Impressive.

Thanks! I appreciate the feedback and insight

Cut it off if you're tired of looking at it, even though, yes, palms use nutrients in older leaves for new growth as mentioned above. Sometimes, for aesthetic or safety reasons, you have to trim off unsightly leaves before they are totally brown; it's not going to have seriously detrimental effect on the plant.

just trim the leaf itself. Cutting of leafs on a crownshafted palm is not good
