You never came home at night in the summer with your windshield plastered with gray-white greasy moths that windshield washer would just smear around? ECB.

I'm sure there was a lot of ECB damage in the '70s-early '80s. We'd scout & often find "shot holes", then find the larvae. 2-3 larvae per plant? Spray.

At least there was a chance to try & control ECB with post sprays. But, you could get re-infested & have to spray again. I think most effectiveness was around 75%. Never got 100%.

With CRW....there is no rescue. Better luck next year!
