Red Spidermite damage & other photos
These plants were so pretty and healthy last week. How quickly things change...
Red Spidermite infestation on Japanese Black Triefele: Faux Red Brandywine infested too: Sophie's Choice has spidermites as well as blight & powdery mildew problems, and like everything else I have, leafminer damage. If you look closely, you might see the webbing and small dots that are the red spider mites. Several sprayings will ultrafine oil, thyme oil, and water over the last couple of days may have damaged the leaves, but I still see the mites moving around. Now trying Neem. Spots on Snow White Cherry: Suspect fungal, even though I have been spraying w/ Daconil. Our weather had been humid, sunny and hot during the day, and raining at night. Sudden wilt of sweet baby girl... Suspect Sclerontinia sclerotiorum. Found the white powdery stuff on the stem near the soil-line. As my luck would have it, after I cut away all the foliage and finally saw the white powdery mold on the stem, a blast of wind dispersed it in the direction of adjacent tomato plants. Would appreciate any suggestions to prevent this infection from spreading to other plants. |

What really sux is that some folks will tell you that if you just increase the humidity then you won't have problems with the mites. I wish that were the case, but as you know, it doesn't always work that way in the warmer climates. What I've found is that when I tried to do that by hitting the plants with frequent sprays of water, I still had the mites *and* also got fungal disease to boot for my trouble. What I do now is to alternate my Daconil sprays with my Pyganic sprays, and that seems to work fairly well. I have also mixed the two (I know, not recommended by Ortho) with great results. |

I am so glad you posted this... often I feel like such an oddball. Thanks for the info on pyrethrin products. That is eye-opening to hear of the rotenone in pyrethrin products. If I had seen rotenone on the label, I wouldn't have bought it. Thank you for the information on Pyganic. Good news to hear you had good result mixing Pyganic w/ Daconil and that I don't have to wait days after Daconil application to use it, since I often need both at the same time. Have your plants ever fully recovered from decimation like mine? My Japanese Black Triefele looks mostly dead, but it's still drinking water, so I'm hopeful. |

Suze,
I'm guilty of repeating that suggestion as far as misting to get rid of mites. Maybe it works in Arizona.
