Here are some others that are perhaps not as well known:
Pea broth is essentially the outcome of the worst pea soup recipe you can imagine: nuke some frozen peas at 121°C for 15 minutes, strain the resulting sludge, then nuke it again to sterilize. We've used pea broth to grow oomycetes of the genus Phytophthora, which are responsible for the destruction of a wide range of plants including potatoes, oak trees, and cucumbers. A pea-based medium has also been used to grow the delightfully named fungus Botryotinia fuckeliana, which causes gray mold on a bunch of plants including peas. Karl Wilhelm Gottlieb Leopold Fuckel was a 19th century German botanist who focused his studies on fungi.

V8 vegetable juice is enjoyed by several fungi and oomycetes, including Thielaviopsis basicola (responsible for a plethora of plant diseases including a black carrot rot) and members of the genera Phytophthora (aforementioned destroyers of many plants) and Pythium (commonly found in soil and particularly good at killing seedlings). The blend of tomatoes, carrots, celery, beets, parsley, lettuce, watercress and spinach provides a convenient mixture that can support the growth of fungi capable of infecting plants or people. One thing V8 juice does particularly well is convince fungi they should make offspring via a process known as sporulation. Getting fungi to make spores is sometimes super annoying, but is necessary in order to understand how they spread between hosts (by producing spores that can be carried by wind/animal vectors/etc.) and acquire new abilities through sex. In particular, V8 juice has been used to study the sexual development of Cryptococcus neoformans, a fungus that causes disease in humans but also tends to live in old trees.
Oomycetes (Phytophthora and Pythium) can also be grown using straight up tomato juice (prepared fresh) or liquid squeezed from pulverized soybeans. This is useful since V8 juice can potentially be difficult to acquire in certain parts of the world. It also can address the issue of using a commercial product that could potentially be altered by the manufacturer unbeknownst to researchers who use it.

Orange serum (the result of heating up orange juice and then filtering it to remove fruit particles and precipitates) provides a good growth medium for fungi that spoil citrus fruits (e.g. Penicillium digitatum). This stuff has also been used to grow the following:
- Fungi living in association with Lophelia pertusa, a deep-sea cold-water coral notable for its ability to form large reef structures that serve as biodiversity hotspots in deep waters
- Apparently harmless fungi living inside Norway spruce needles while they are still green and attached to a tree
- Gremmeniella abietina, responsible for Scleroderris canker on coniferous trees

The liquid left over after boiling asparagus spears in water can support the growth of Fusarium oxysporum and Fusarium proliferatum, toxin-producing fungi capable of eating the roots and stalks of asparagus. I came across a paper from 1903 that mentioned using asparagus juice to grow species of Fusarium causing bulb rot in flowering plants such as crocuses. The juice has also been used to grow Cryptomyces pleomorpha, a mysterious fungus (it likely encompasses several bacteria and fungi thought to be different forms of the same organism) isolated from the blood of a cancer patient and briefly suspected to be carcinogenic.
It's not technically juice, but pureed carrots can be used to grow the fungi Gibberella fujikuroi (consumer of several plants including rice and corn, can also cause opportunistic infections in animals) and Gibberella zeae (damages wheat, barley, and other grains). Both species produce toxins (e.g. fumonisins and gibberellins) so even if infected plants can be harvested they're often not usable.

Aschersonia placenta, a fungus that infects scale insects capable of spoiling tropical fruits such as durian and guava, grows particularly well on mushed up pumpkin. Citric acid-producing Aspergillus niger also likes to eat pumpkin juice, although optimal acid production is achieved when the fungus is fed a combination of pumpkin and molasses.
