![]() (Biosphere 2 was inspired, but it shows just how clueless we are in thinking we can manipulate ecosystems and make it work out without taking the least among us into account. We just need to be careful about everybody in the food chain we have failed to do that with too many creatures and our understanding of operating ecosystems is so poor we cannot sustain one of our own making for more than a few months. Disease is a dominant culture, and Nature provides some very good tools to fight it. Exact same bacteria, to be specific.Nature always wants to balance itself it does not like dominant culture of any being and usually sends something along to counter it. You know how yogurt won't go bad, because it already has a bacterial culture? Exact same idea. after rain because you wash a good deal of last times calcium off (not so much the bacteria, as bacteria produces a sugary glue to stick itself, but still some are lost). Keep pruning off the dead as soon as you see it going and treat them like I said and you'll get through this.Ībsolutely and you can't really do it too much. But I had a plant or two hit hard last year and eked them along until the fruit ripened you can do this. ![]() I prune off the lower foliage as soon as plants are big enough to allow by the time they are three footers the bottom foot of foliage has been sheared off, and with everything above, I stay pretty clean. Neem oil has proven somewhat effective, but only when caught early, and that does not seem to be the case here. And develop good live soil ecologies that inhibit badguys, who are only 5% of the total biology mix in a healthy environment. Spread some good mulch under your tomatoes to keep water borne disease from splashing up. Liming the soil will help next year, but milk gets it into the plant much quicker than a mineralized form. Also the calcium in the milk is very important here as well seems calcium deficiency in plants is a key factor in early blight. This encourages Lactobacillus bacteria that have low level antifungal properties to colonize the leaf surfaces, called antagonistic biological counterculture, and no matter what you call it it sure does help with early blight. Mix milk to water, one to ten, and add a splash of fish hydrolysate, and water leaves with it after every rain or foliage wetting. I have harvested good fruit off of plants blasted with early blight you can help them through this but not by killing every fungus in a ten foot area, including mycorrhizal fungii supporting your tomato's root sysytem, or the Trichoderma fungus that has been killing a lot of other fungii that didn't end up attacking your plant. I can't tell you what to do, Dave, but I can ask, please don't go there. and we haven't even begun to talk about what it does to the environment. Possible carcinogen, low level toxicity for humans.eExtoxnet page says it stays persistent in plants and some metabolites do make it to harvested fruit. Yeah, early blight for sure.do you use a mulch under your tomatoes at all Dave? That can help a lot with the splash up diseases, as can watering in the AM rather than at night.ĭaconil? On a food crop? Read that MSDS, Dave.
