I had a healthy garden up until about two years ago when a tropical rain storm came through and rained for 3 days. A few days after the rain stopped, I noticed a whitish, moldy look on some leaves. Soon after that, the leaves developed dead, brown spots, withered and then eventually died. This issue spread throughout my entire garden. I have tried Copper, Neem Oil and Daconil with no luck. Someone advised me that a Systematic Fungicide may be applied to the soil as well as to the newly emerging plants but I’m not sure if that is what I should do as I am not sure what the problem in the garden was in the first place? I plan to regrow cucumbers, tomatoes, watermelons, strawberries, peppers and onions, can you please provide me with advice on which product or products I need?
This sounds like downy mildew and/or tomato blight.
What I would suggest is to first amend the soil with compost. I would also add some 10-10-10 or Garden food to the soil as well. Then, roto-till the soil so that it’s nice and fresh. Adding these materials will give some of the nutrients back into the garden.
After amending and roto-tilling the soil, plant all of your plants like you normally would. Once everything is planted, use Agri-Fos as a Foliar spray.
For the Tomatoes and Peppers the rate should be 2tsp to 2oz per gallon of water every 2 weeks.
For onions it should be 4 tsp. per gallon of water every 2 weeks.
For the Strawberries use 2 to 3oz per gallon of water. This should be done at time of planting than 14 to 21 days after and then repeat at 1-2 month intervals when disease is evident.
For the watermelons and cucumbers apply 1 oz per gallon of water. Apply within 7 to 10 days of infection and repeat every 2 weeks as necessary.
We recommend the use of Agri-Fos immediately after planting due to the fact that the disease was previously present in the soil. Agri-Fos can be sprayed on the plants up to 7 to 10 days before harvest.
