I lost a huge tomato crop last year and I need to try to prevent it this year.** A: Yes, George! I have used it the last couple years on my tomatoes and cucumbers and it really works. Start using it early, even before any signs of disease and continue to spray it on every week. Rotate your crop so you aren't planting were you had blight last year, it remains in the soil from year to year. I also plant in black plastic to help separate the plant from the soil. Be sure to spray the lower leaves the most. Good luck! **Q: what ratio water to concentrate?** A: Low end for preventative and low density pest problems. Higher concentration if severe issue is present. Try to use the lowest concentration that works for YOUR situation. Read entire label carefully. Ask questions with YOUR county extension agent or Dept. of Ag State Inspector for your region. Saftey first. **Q: Does this work on Damping Off root rot for seedlings?** A: Being that you are talking about the seedling stage of growth, this product won't work. Wait till the soil is warm to plant. If the plants had leaves to absorb the product, then the Bonide would be beneficial to use, but it will take several treatments. Keep in mind that rain or irrigation water will wash the product off the plants requiring retreating. **Q: anyone use this for cedar rust fungal infection on Apple trees? thanks** A: yes a copper fungicide will work .
