Knots and the surrounding wood have different densities. Since knots are more dense, they expand and contract less than the surrounding wood, loosening the bond. To protect against this, use a Premium or #1 board with both faces graded. The knots will be smaller and intergrown. The cost is slightly more, but your fence will have a longer serviceable life.
