Wayne says... Is this what the leaves look like Kerri, if so here is something that might help. ""Black Spot on Pawpaw Adequate nutrition is as much a tool in disease control as the use of sprays. Plants deficient in potassium, phosphorous and magnesium are more susceptible to attack by black spot and powdery mildew. Simply increasing the potassium (sulphate of potash and/or lucerne mulch), phosphorous (rock phosphate or chicken manure) and magnesium levels (Epsom salts) helps to make plants more resistant to disease. Pawpaws are most susceptible to black spot disease during the cooler months. Spraying with sulphur or copper based compounds prior to the onset of the cool weather and watering with liquid seaweed can help reduce the severity of infestations. ""

Ali Rose says... Hi, I Work at Nashville State School in the Permiculture Garden and year 2K are investigating how to get rid of blackspot of the paw paws. We supply these as organically grown to breast feeding mothers from the playgroup to help with their milk supply and as such do not want to spray with copper sulphate. Other then the above are there any other known methods for helping our trees beat this?

Wayne says... Hello Ali Rose Are they spotting on the tree or only after you pick them. Perhaps sprinkle a good coverage of dolomite around under the tree and water it in. I would consider spraying the fruit with a solution of pure uncented liquid soap and water, say 30ml per 2L water, it must be uncented. The others might have better ideas to help you out as it is for a good cause, congratulations to you and the kids | About the Author Wayne Mackay QLD 26th October 2009 7:06pm #UserID: 338 Posts: 908 View All Wayne's Edible Fruit Trees |

Brendan says... Hi Richard, The guru here says; 'Pawpaws falling off, trees need gypsum AND dolomite'. Gypsum @ 4 handfuls per sq metre/yard, dolomite @ 2 handfuls per sq metre/yard. I'd give it some sulphate of potash fertilizer as well, 1 handful per sq metre/yard. Mulch well, but keep away from the trunk. | About the Author Brendan Mackay, Q 25th June 2011 7:05am #UserID: 1947 Posts: 1722 View All Brendan's Edible Fruit Trees |

Mike says... I lose the plants routinely and try to have 6 or 7 with new recruits coming on.Paw Paws are very prone to root rot diseases in heavy soil after wet weather, 'bunchy top',fungal spotting and fruit rots (like mango fruit rot).While they can grow through these occasionally when growing conditions are good you have to accept casualties.They don't like excess fertliser close to the trunk,too much lime,salt or chlorides and fruit drop and leaf burn can result. Sick trees can be mulched, supplied with friendly 'organic' fertilisers,light dolomite,micronutrients and P and K.Copper oxy or mancozeb doesn't usually seem to cure fungal problems and there are no hot water or chemical dips that treat rot rot in fruit. | About the Author Cairns 25th June 2011 8:34am #UserID: 5418 Posts: 1438 View All 's Edible Fruit Trees |

Jason says... On most forums there's not really such a wide climate range as there is on this one so there not usually a mixing of Queenslanders with the Californian/Southern Australia/NZ climates. But because we have such a wide range here it's best to use Papaya when talking about c. papaya to get in line with the rest of the world outside the Queensland border | About the Author Jason Portland 25th June 2011 4:46pm #UserID: 637 Posts: 1217 View All Jason's Edible Fruit Trees |

Wayne says... http://www.daleysfruit.com.au/fruit%20pages/pawpaw.htm So what do you think, perhaps we should refer to the American pawpaw as Asimina triloba It is confusing to some for sure | About the Author Wayne 25th June 2011 6:09pm #UserID: 338 Posts: 908 View All Wayne's Edible Fruit Trees |

Mike says... For most Australians paw paw is the only name for C.papaya having long ago accepted the west indian name for the fruit rather than american.Interestingly the name paw paw for Asimina came about due to its resemblance to C.papaya fruit and the early yanks chose the WI common name for C.papaya.Asimina is often called wild banana,kentucky banana and lots of other names. Saying all that it is probaly better to say Asimina and papaya to avoid confusion. | About the Author Cairns 25th June 2011 8:46pm #UserID: 5418 Posts: 1438 View All 's Edible Fruit Trees |

Carolyn says... I have two young red papaya trees and they were coming along nicely, however nearly 2 weeks ago my neighbour accidentally sprayed his citrus trees with Gramoxone (a herbicide) which drifted over to my backyard, leaving brown spots on everything it touched. The leaves on the papayas were also affected but they didn't seem to suffer too badly, until today when the younger leaves at the top started wilting. I noticed the trunk up near the new shoots is looking sort of puckered and dimpled but am not sure if this was there before or is it a result of the spraying. Does anyone know of a disease that could cause this? | About the Author Carolyn Buderim 9th January 2012 7:43pm #UserID: 6374 Posts: 4 View All Carolyn's Edible Fruit Trees |

snottiegobble says... "accidently sprayed his citrus trees with Gramoxone" Er, I dont think so Carolyn! This is like a farmer in the Otways who ariel sprayed his crop & completely ruined a thriving vineyard next door. It took years for the vines to recover & stop producing mutant growth & grapes!

Carolyn says... No, it's not good enough! The guy is an absolute idiot ... what he was trying to do was spray some "big black ants" that were climbing up and down the trees. The spray he intended to use was also used to treat termites, but I can't remember the name of it now! I don't know which was worse!! | About the Author Carolyn Buderim 11th January 2012 11:40am #UserID: 6374 Posts: 4 View All Carolyn's Edible Fruit Trees |

Jantina says... GGRRRRR! that is precisely my beef against people who spray toxic chemicals around. Some of them are incapable of thinking past their own immediate want ie. get rid od some ants. I have experienced being covered by chemicals from aerial drift twice when pilots ignored the fact that strong winds were blowing, had my plants killed by careless spraying and seen similar events to that which Snottie refers to. Complaints to authorities fall on deaf ears. And some of that stuff persists in the environment for hundreds of years. It,s time people were made accountable for their actions. Poisons are far too freely available for any idiot to spray and cause irreversible damage. | About the Author Jantina Mt Gambier 11th January 2012 12:21pm #UserID: 1351 Posts: 1272 View All Jantina's Edible Fruit Trees |

Mike says... Unfortunately the use of pesticides is here to stay and there is actually a trend towards less toxic ones.The with-holding period for insecticides and fungicides gives a clue to their relative breakdown rates.There aren't anywhere near as many bio-accumulating ones around.Herbicides are also not as strong or persistent as in the past.There are a few baddies however that can cause environmental harm and adversely impact people.You can access the particulars of just about all of them and see what their specific risks are, their LD 50's etc.There are huge problems with inappropriate uses, concentrations,uses that expose people,animals and watercourses to poisoning.Regulatory authorities are weak and often unresponsive and much could be done to tighten usage. | About the Author Cairns 11th January 2012 5:33pm #UserID: 0 Posts: View All 's Edible Fruit Trees |

john says... I have an horticultural text from the 1950's that recommends lead arsenate as a treatment for a wide variety of fruit problems. We have moved on. Most of us are attempting to be organic but if that means we end up with no fruit and need to purchase what we did not grow ourselves then excess purity is a little futile. | About the Author 12th January 2012 6:28am #UserID: 0 Posts: View All 's Edible Fruit Trees |

Carolyn says... In the meantime, what can I do about my pawpaw problem, regarding the young leaves wilting and the top of the plant looking dehydrated. They're no more than a metre tall, and don't seem to be growing very vigorously since they copped the spraying. I only bought them a couple of months ago. Most of the trunk seems fine, so if I cut the affected top part off will it branch out the sides? | About the Author Carolyn Buderim 13th January 2012 6:37pm #UserID: 6374 Posts: 4 View All Carolyn's Edible Fruit Trees |

snottiegobble says... Amanda,did he/she protect it with plastic during the winter like I did?. I would like to know because my papaya is headed for 3 mts & it will be difficult this year! I was using crossed poly pipe to support the plastic which only comes in 2m wide rolls! Thats builders "grunt" by the way & splits along the fold after about 6 months, worse luck! Carolyn,thats what they do to stop bunching tops initially caused by some sucking bug! Never tried it myself, I just picked the best of the bunch, cut all the other growths off & away she went after a good feed of potassium s. & seasol. | About the Author snottiegobble Bunbury/Busso (smackin the middle) 14th January 2012 7:27pm #UserID: 3468 Posts: 1458 View All snottiegobble's Edible Fruit Trees |

jimroz says... It looks like it might be Fruit Spotting Bug. No cure, but you can try cutting tree off below the damage to healthy stem and put a tin can on top to stop rain getting in. Give it a good fertilize with some Dolomite, well rotted manure and Potash (Fertilizer info from Brendan in another forum),and new growth should pop out.Picture is various stages of the bugs life cycle. Good Luck!

Peppercorn says... I have about 8 Paw Paw plants in my backyard that have been effected by all the rain we've had. All the leaves have gone yellow and some have fallen off but, I'm confident the plants will survive. However, I cut off the tops where there was a rot happening, and hundreds of little black ants crawled out from the centre of the stalk. The plants have attracted the stinkbug, the one that sucks the sap but, do THEY cause the rot or is it the black ants? Is there any way of ridding the plants of the bugs?? My plants look just like the photo's that Elaine Styles posted on this thread. thanks for any help. | About the Author Peppercorn Tewantin 21st March 2020 2:44pm #UserID: 21830 Posts: 2 View All Peppercorn's Edible Fruit Trees |
