You can apply Hi-Yield 2, 4-D Selective Weed Killer to the grass directly after it has rained, however the product may not stick to the grass as well. If you add a surfactant you may get better results. This product will still work, however it may not work as fast, or you may need to treat again. For optimum results it is best to apply it once the grass has dried.
