My question is can we get away with just thoroughly rinsing the stems and leaves under a strong cold spray of water from a shower-head spray, and “squeegeeing” each leaf between thumb and forefinger under running water — that should physically (not chemically) remove any OE spores, right? Bad weather, spring droughts, dwindling supplies of wild milkweed, and other factors also contribute to the decline.
