Controls mildews, blights and other tough fungal diseases such as Septoria leaf spot on tomatoes (shown in inset). More effective than other copper-based products; uses less copper. Apply up to harvest. Pint makes up to 16 gals.
We've used various sprays for several years including copper powder mixed with water. The copper definately works the best. In 09 we used the soap shield and and saw a big difference in how long the tomato plants stayed healthy. This year looks same as last so far. The plants look great going into the hot part of summer.
