I am told that our allotments get very bad blight each year so I have been trying to find an alternative to Bordaux which I'd rather not use. I found this information and was wondering if anyone had tried this with any success.
"Compost and Manure Teas
Many people have success with manure tea keeping blight and other pathogens away from plant. Soak the area around plants and use as a foliar spray. Do not use on seedlings as it may encourage damping-off disease.
Fill a 30 gallon trash can with water. Let sit for 24 hours to evaporate the additives (use rain water if you can). Add about 4 shovels worth of manure to this and cover. Let it sit for 2-3 weeks, stirring once a day. Strain and apply as needed.
Various manures supply nutrients as follows:
Chicken manure: nitrogen rich: use for heavy feeders such as corn, tomatoes and squash.
Cow Manure: potash: use for root crops.
Rabbit manure: promotes strong leaves and stems.
Horse manure: leaf development.
Compost Tea: Make and use just the same as you would the manure tea. This is another terrific reason to compost all those prunings, grass clipping and kitchen wastes. Or you can use our HumAcid for a ready made foliar spray with all the goodness of compost!"
