Can you tank mix Daconil with carbaryl or permethrin?
In a response to a qyestion at a Texas A&M ag extension site at:
http://aggie-horticulture.tamu.edu/a...es/tomat2.html they indicate that Daconil can be tank mixed with common garden insecticides. Wondering if anyone here has any specific experience with this? "Q. I planted the tomato varieties which you recommended and they are loaded with tomatoes. Now the leaves are beginning to turn yellow, then brown, then die from the bottom of the plant. What should I do; will this kill my plants? A. You and everybody growing tomatoes are having the same problem. Tomato plants are developing brown spots on the lower foliage. This is the result of a fungus infecting the foliage causing a disease known as early blight. Early blight is an annual problem for most gardeners. It normally develops into a problem when plants have a heavy fruit set and the area has received rainfall. Spores from the fungus are spread to the lower foliage by wind and splashing rain. Leaves must be wet for infection to occur. At 50 degrees F. the leaves must be wet for 12 hours for infection, but at temperatures above 59 degrees F., the length of time for infection is only 3 hours. Leaf spot development is most severe during periods of cloudy days and high humidity. To control the fungus, foliage applications of a fungicide must be made every 7 days until moist conditions (dew included!) no longer exist. Applications should begin when the first fruit is slightly larger than a quarter. Chlorothalonil (Ortho Multipurpose Fungicide or Fertilome Broad Spectrum Fungicide) and mancozeb hydroxide (Kocide 101) are fungicides used on tomatoes for early blight. The copper fungicides also are affective against the foliage and fruit-infecting bacterial pathogens. Benlate (Greenlight Systemic Fungicide) should also be added every second spray application to prevent Septoria leaf spot. All listed fungicides can be mixed with insecticides or other fungicides except the copper-based materials (Kocide). The copper fungicides have a high pH which will reduce the life of many insecticides and some fungicides. Kocide is the only effective organic control for this pestilence. "

Rebel,
I don't see anywhere on my Daconil label that recommends against it, but in this thread Carolyn called Ortho and they recommended not to tank mix: http://www.tomatoville.com/showthread.php?t=7922 Maybe try it on a few plants to compare effectiveness. Steve |

Also, I see in my label (at the end):
"If you have any questions relating to product use or application, please call 866-945-5033." |
