| I have about 15 varieties of tomatoes growing. I have sprayed Daconil 3 times so far. Always in the morning when the leaves are still wet from dew. I have noticed the day after the sprayings that my Persimmon and German Queen plants got burnt leaves and probably 90% of the blooms turned brown and aborted. The persimmons were full of flowers. Are these varieties more susceptible to chemical burn than others? |

| I know Daconil very well. The attachment sites for the fungal foliage diseases are on the upper leaf surface and when Daconil is used at the right concentration it binds to those attachment sites and prevents the fungal spores from attaching. So I don't know what's going on with the destruction of blossoms. All I can think of is that if the wrong concentration of daconil was used and theleaves were wet with dew, that when the sun came out that holes were burned on the foliage and you should see those holes, and that b/c what's on the leaves acts as a prism, concentrating the sun's rays. I have heard of that when other products are sprayed on the foliage, I can't remember which ones right now but I know that soap is one of them. So no, I know nothing special about either german Queen or Persimmon as to sensitivity to Daconil, I've grown both but no way can I remember if I was using Daconil when both were grown. But in the past I've used Daconil with thousands of varieties and never a problem. Daconil iis the most widely used anti fungal in the world and more data is known about chlorothalinol, the active ingredient in Daconil, than all other anti=fungals. Carolyn |
