What causes white rot?
Introduction. White rot is a very serious disease of garlic and onion (Allium species) due to its highly aggressive nature: it can survive for a lengthy period of time in the soil between crops and spreads easily. The disease is caused by the fungus Stromatinia cepivora (Berk).
Which fungicide best for onion white rot?

How do you treat white rot fungus?
Treatment involves mixing soil with fungus and a suitable substrate such as wood chips. White rot fungus has been tested in situ (i.e., in place) and in an above-ground bio-reactor. Moisturized air on wood chips is used in a reactor for biodegradation.
How do you control onion fungus?
Crop rotation is important to prevent pathogen populations from building up to high levels. Rotations out of onions for 2-3 years are recommended. Most commercial onion crops must be protected from purple blotch by using repeated applications of protective fungicides.
How can I make wood decompose faster?
Add Green Materials. Mix in roughly equal amounts of green organic materials, such as green grass clippings, vegetable scraps and manure. Shred or chop these materials as small as possible for rapid decomposition. Adding nitrogen to wood chips is essential to the composting process.
Is white rot fungi toxic?

Can you overwater onions?

How do fungi take in nutrients?
Fungi are heterotrophic. Fungi are not able to ingest their food like animals do, nor can they manufacture their own food the way plants do. Instead, fungi feed by absorption of nutrients from the environment around them. They accomplish this by growing through and within the substrate on which they are feeding.
What can digest lignin?
Fungi are the only major organism that can break down or significantly modify lignin. They’re also much better at breaking down cellulose than most other organisms.
How do you add urine to compost?
To add pee right to your garden, instead of to your compost bin, be sure to dilute to a 10:1 ratio. Urine can be collected in mason jars, or if you are coordinated (or male) you can pee straight into the bin.
Does Epsom salt rot tree stumps?
When used as directed on a tree stump, Epsom salt will dry out the root system, and prevent it from absorbing the moisture and nutrients it needs to live. It will also dry out the tree stump itself, which will cause it to rot and break down, at which time it will be easy to manually remove.
