A seed tube guard for agricultural planters is cast from a high-chrome cast-iron alloy or manufactured from other wear-resistant material. The seed tube guard has a leading front surface, a trailing rear surface, and respective right and left surfaces. A fluid delivery channel is integrated within the body of the seed tube guard between the leading front surface and the trailing rear surface, and between the right and left surfaces. The fluid delivery channel has an entrance and an exit with the exit located below and rearward of the entrance for delivering fluid into a seed furrow ahead of a seed tube exit.
