The visitors could have led when Junior Stanislas went on a fine run only to see his shot cannon back off the post.
Ross Wallace also saw a decent attempt saved by Matt Gilks but Blackpool also hit the crossbar through Tom Ince as both sides struggled to play passing football on a terrible surface.
Ludovic Sylvestre's stunning strike won the game for the home side, and Dyche said: "On that surface it was either probably going to end up as a mistake from someone or a quality finish.
"It was a tight affair. They had the better fist of it the first 25 minutes but I actually thought they managed to play on that surface.
"We had pockets of it as the half went on, their keeper made a brilliant save against Wallace which is the best I've seen for quite some time.
"(In the) second half the quality softened because of the pitch - which is the worst I've ever seen in my career and I've played on some bad ones, I can assure you.
"I'm absolutely sure Paul Ince wants to play on a better surface than that but it is what it is - there are no excuses, I want to make that clear.
"We came with a game plan to deal with it and we did go close, if Junior's shot is half an inch to the right it goes in."
