Simazine 4L Herbicide is not labeled to be used on soybeans, so we would not recommend it. The only mention of soybeans on the label is a precaution stating, "In western Minnesota and eastern parts of the Dakotas, Nebraska, and Kansas, do not plant soybeans following corn treated with SIMAZINE 4L if more than 2 qts. of SIMAZINE 4L per acre (or equivalent rate in a band) were applied, as injury may occur."
This product is labeled to be used on Red Pine (Norway Pine) and White Pine, however, it is not labeled specifically to be used on seedlings. Pre emergents stop seeds from germinating, and pre emergents are normally recommended to be used on established plants and grasses as instructed.
Please be sure to review the product label for more information and complete application instructions.
