| Your tree has suffered spray damage, so you want to spray it some more? |

| Can Neem Oil really cause a problem like that? Or is the "cause /effect" really just coincidental? I have no personal thoughts on this. I was just getting ready to spray the same product. Now I'm just going to wait for experienced opinions. |

| thats one of my questions at the recomended dosage should neem oil do damage. spots on leaves seem now to develop into holes. i usually spray every ten days. don't know whether to wait or not. |

| Yes, it can cause damage if used too heavily, if applied when too hot or sunny. That may not be your problem but the timing and nature of the injury are suggestive. I wonder why you're using it on that tree now. Or why you'd want to spray something when you don't know what the problem is. |

| I don't see much reason to ever spray neem on a peach tree. Its not going to do much to help with diseases, and you probably don't have aphids or scale. The one thing it can be useful for is the white peach scale on trunks, spray dormant strength in spring for that. Any oil sprayed in hot weather can cause damage. Figure out what disease you have and then research and plan an appropriate control program. If you don't have a disease or pest, there is no need to spray. Scott |

| Hi Marcantonio, Did you apply the neem oil when the sun was still shining? I have been using neem oil for the last 3 years on my peach, plum and fruit cocktail trees and it works for me. However, I will not give those little pests the opportunity of building up a resistance to the oil so I am incorporating other solutions in my insecticide regime along with the neem oil-like home remedies; a mixture of cayenne pepper, garlic clove, mineral oil and a little dish detergent. When using most insecticides, you want to do it early in the morning before the sun comes up. Because I work until the evening, I do it in the evening although I try to make sure that it doesn't get too cool as to cause other problems like fungus, mold and mildew. I am in the deep south-georgia-and we have a lot of hot and humid weather here so I am always taking care to make sure that I dont spray anything during peak sunshine which is a lot in this location. You mentioned using spectricide as well-could it be that instead of the neem oil? I also allow the daddy long-legs to hang out on my fruit trees as well. I don't dismiss them until harvest time and then I just gently take them out of the trees along with their webs. I don't harm them, I just relocate them to my rose garden. LOL. They consume quite a lot of the little insects trying to make holes in my fruit and flowers as well. I have been gardening for about 8 years steadily and its been a lot of trial and error and it always will be-that comes with the occupation. LOL. However, if something doesn't work for me, I eliminate the product (provided I have done everything according to directions) and I go on to something else. You are in New York and the weather is very different than it is here in georgia so conditions will not be the same. I have always just used just 1 capful of neem oil to a gallon of water and I spray lightly above and under the leaves-within 1 week I saw a difference-that was 3 years ago and it has been a faithful product in my collection of insecticides, pesticides and fungicides since. Marcantonio, keep looking for products to take care of your specific concerns and you will find one-just don't give up because there is nothing like home-grown fruit and produce. It will be worth the effort in the long run! Schucks, a sun-ripened peach is simply indescribable but I guess you know this, thats why you are seeking help. Good Luck. |

| ahgrower, bugs don't develop resistance to neem. Some bugs just don't get bothered by it. For example plum curculio could care less about a little neem oil. If you are setting those guys back it must be from something else you are spraying. I use Surround clay to deal with them. The only thing I ever had neem help with was aphids and I don't get aphids on my peaches. What problem did you have that the neem solved? Scott |
