nice find BOM... you jusat added 1 to my "get list"
Nice Wiz! Makes me mouth waterI was growing them for their nitrogen fixing properties..hadn't thought of screening..
Can I use that soil in the bag that's never been opened, but was subject to a sever fungi infection and expect a clean grow?
Ultimately, you'll need to keep humidity very low to prevent re-infecion and not get leaves wet when watering... it cant live without moisture.Septoria Leaf Spot
Symptoms
Septoria can infect all above-ground parts of the plant other than the fruit but infections are most obvious and extensive on the foliage. The infections are characterized by small (1/8″), circular lesions with dark borders and grayish centers. Close inspection reveals tiny black or brownish dots within the lesions. These are the spore producing structures (pycnidia) of the fungus. The leaves eventually wither and die. The disease progresses up the stem and total defoliation of the plant may finally occur.
Survival
Septoria survives the winter on infected plant debris including tomato and related plants. The fungus may also be transmitted by infected seed and spores can be present around growing facilities such as greenhouses, cold frames, flats, etc.. Where spores have survived the winter, initial infections may begin early in the year. Otherwise, the fungus will not sporulate below 59oF which delays the onset of infections. The spores are splashed by rain, blown by the wind, or carried by insects and other animals (including man) and once the initial infections have started the fungus can produce new spores which rapidly increases the rate at which the disease spreads.
Control
- Use disease-free seed or if the seed is suspect use a hot water treatment (122ºF for 25 min.). This practice may reduce seed viability.
- Remove and destroy crop refuse at the end of the season. Where this is not practical, plow the refuse into the soil at the end of the season which will promote rapid breakdown by soil micro-organisms.
- Practice rotation (3 years) to non-susceptible crops. The most effective rotations will also try to exclude susceptible weeds.
- Promote good air circulation by spacing plants properly.
- Hand-picking infected leaves will reduce the number of spores available for new infections.
- Stay out of growing areas when the foliage is wet.
- Water early in the day and, if possible, avoid wetting the foliage.
- Stake plants.
- Be sure plants have adequate nutrition.
Finally got myself a new camera

Nice Wiz! Makes me mouth water
Assume it is contaminated and get new / clean...
reason being... one spore on the outside of that bag makes it into the soil... and you're re-infected. and spores are sooooooo incredibly tiny (microscopic)
for disinfecting surfaces... use H202 in place of bleach
