The Q&A Archives: Peach Tree

Question: Our peach tree had peach leaf curl, we sprayed the area with a insect killer and the portion that we sprayed the leaves turned brown but the top is green and flourishing. I;ve found articles about the peach leaf curl and I think I understand that but we have gobs of a jell sticky sort of stuff coming out of the trunk and branches-can you tell me what that is and if we need to do something.

Answer: Peach leaf curl is a fungal infection; an insect killer would not control a fungal infection. It is impossible to control this once it has appeared for the season. It must be controlled before it appears. It is controlled by treating either in late fall or early spring. So you should not be treating for it in midsummer. Here is more detailed information about it.

Please check with your local county extension as to what product to use and how/when is best to apply it in your local area. Also, read the entire label and follow the directions on it carefully and completely.

Some sprays will damage foliage if applied at a high temperature, at the wrong time of year, or on a plant that is not listed on the label. Always make sure the product you are using is intended to control the specific problem and is listed for use on the specific plant you want to treat. Apart from risking damaging your plant, "the label is the law" and to apply something outside the label directions is illegal.

Peach trees may ooze wherever there is damage to the trunk such as from a weedwhacker or borer infestation.
