Peach leaf curl free peach?
Comments (7)An alternative option is to take a method from fig growers, who bundle up their trees to protect them from cold. The difference is that you can bundle up peaches to protect them from rain. I live in W. Washington and peach leaf curl is rampant. It takes using small pruned, or genetic dwarf, peach trees like Ponderosa (Or is it Bonanza?) or Honey Babe or Garden Gold (My varieties). I bundle up the branches with twine, each major branch being one bundle. Then I cover each bundle with a white plastic trash bag "sheath" and tie that in place as well. Keeping the rain off the buds, prevents peach leaf curl spores from getting into the buds and growing. I've sprayed the bundles before covering with copper spray but not sure if it's necessary. The bundling needs to be done in November. Then in February, I remove the trash bags and unbundle. I watch for when buds begin to swell, then remove the bags. This technique changed my peach loss from almost 100% to an overabundance of peaches. Only a few leaves were infected wtih leaf curl. I also did this with a Tri-lite peachplum, which is not genetic dwarf but is small. It worked for that as well. I plan to keep it pruned small so that the bundling is reasonably easy....See Morepics of peach leaf curl- despite using copper
Comments (33)I love these "tips". How bout a little research backup before someone looses a crop on an experiment. Peach leaf curl is an unpredictable disease so anecdotal observation is not going to be a very useful method of evaluation. Lychee, did you get my e-mail? Chlorothalonil aka Bravo, Echo, Applause, and Concorde is not a restricted material in NY which is one of the most restrictive states, 2nd to only CA I reckon. Or at least it wasn't as of the publishing of the Cornell 2007 Tree Fruit Pest Managment guidelines. It's use as a brown-rot control for peaches is limited to early application which doesn't matter to me either because I agree with Don that there are much better materials for this. To my knowledge however it is still supposed to be the most affective treatment for peach leaf curl and for black-knot on plums which is what I use it for. I don't find peach leaf curl to usually be a very persistant problem if trees are pruned open enough and they recieve enough direct sunlight....See Moredefeated by peach leaf curl - alternatives?
Comments (5)no, very true, MrsG. I have not seen anything like the fervour (and superciliousness) of the no-spray advocates on this forum. I have been growing fruit at my allotment for the last 10 years and have had a harsh education - (gooseberries, long lost to American mildew) Blackcurrants (big Bud and reversion) Raspberries, numerous virus issues and mildew last year too) peaches (well!) cherries (the rampaging birds and the everpresent threat of various cankers, apples (codling moth) pears (midge) plums (leaf curling aphids, strawbs (botrytis and redcore). Had 'em all. So, this would-be organic gardener has had to give in to pragmatism and break out the copper (would have no potatoes or tomatoes, 8 years out of 10 otherwise).....I have not even started on the veggies!!! I guess my point is that it is not worth getting dogmatic and although I don't have to rely on food I grow to survive, I still want to see returns from my efforts. Sometimes though, it just is not possible to have what we want (and I am thinking that growing peaches in the UK is really not worth the bother of covering them with polythene, hand pollinating and continual sprays. Better get going with blueberries then (I will grow them next to the water butts with a seephose)....See MoreCan I prevent Fire Blight the way I prevent Peach Leaf Curl?
Comments (3)It would help, probably a lot, but might not be as fool proof as PLC control. I've never had it in west Texas because it's so dry. But we don't have dew much and it dries off fast when we do. If there is little inoclulum for the bees to carry around and the trees aren't infected to start with, I'd bet on your plan working....See More- 17 years ago
