I have been loosing leaves due to brownish curling and drying up. The main stems are brownish.
I have been researching use of wettable sulfur but the bag does not have any application info.
the more I google the more confused I am. I see ... Don't use in hot climate. Don't apply to plants with flowers. Don't spray on melons or cucurbits. Don't apply if oil was used in last month. I have all of these issues.
I am in hot climate, I used neem a couple of weeks ago. I have melons and cukes in next row in high tunnel. My plants are fruiting and flowering and going downhill fast.
With all of these issues I am looking to test a little as I am desperate but I cannot find any application rate ie tablespoons per gallon for example. Any ideas on safe use of this stuff?
Some photos if interested
