Picante is salsa. Picante is to salsa as grape is to jelly or Taurus is to Ford. It's just a variety of salsa. Picante means spicy, so salsa picante is "spicy sauce." There are also sweet salsas and sour salsas.
To add to the correction, Salsa simply means "sauce." So Picante is just a description of the sauce, or salsa, and it indeed means "spicy," or, perhaps, "sharp." In Spanish, it would be "Salsa Picante," but companies like Pace call it Picante Sauce.
And to correct the original answer, Pico de gallo (not "piccode geillo") in much of Northern Mexico is a non-saucy mix of chopped tomatoes, onions, chiles, and so on. Farther south, it is made with jicama and orange, and is another thing entirely.
