From the letter of the law so long as the branch can no longer live, one may detach fruits from it even if it is still slightly attached. However since people are not expert in this matter it is only permitted to do so if the branch has become completely detached. [ibid]

[6] This is forbidden due to the Mifarek prohibition, as it is the common way to remove the stalk of dates from the tree and then cut the dates off the stalks and send them to storage. This is exactly similar to threshing. Others however argue that threshing only applies to fruits which are concealed within their stalks, as are grains, and not by revealed fruits. [see Ketzos Hashulchan ibid footnote 9]

[8] Some Poskim [Peri Megadim A”A 320] rule that the “Dosh” “Threshing” prohibition applies equally to items which are removed from their stalk even if the fruits are revealed. Meaning that not only by concealed fruits such as legumes in their pods does the prohibition apply, but also by all foods which are attached to a stalk. Nevertheless even according to them it is only forbidden when done in order to store, or eat later on, as is the form of Melacha of threshing that it is done for storage purposes. If however it is done to eat right away then it is allowed according to all, as this is not like Dash at all. Thus one may remove bananas from their stalk, and grapes from their vines to eat right away. However this is only by fruits which it is common to eat the food soon after removing it from its stalk. If however it is common to store the fruits after removing them from their stalk then they have the same law as does removing dates, in which some rule it is forbidden even to do in order to eat right away due to the threshing prohibition.
