Metribuzin
Description
Metribuzin is a selective systemic herbicide that is effective at controlling both broadleaf weeds and some grasses in certain crops. The word 'selective' means it can kill weeds while leaving your crops unharmed, but only if you use it on the right crops. The word 'systemic' means that when you apply it, it gets absorbed into the plant and moves throughout it, killing it from the inside. Metribuzin is most commonly used in soybean fields, where it's very effective at controlling weeds without harming the soybean plants. It can also be used on some other crops like potatoes, tomatoes, and sugarcane. When you apply metribuzin to the soil or spray it on weeds, it prevents them from growing by interfering with their ability to make food. It works especially well on annual broadleaf weeds and some grasses. One of the advantages of metribuzin is that it has residual activity, which means it continues to work in the soil for several weeks after application, providing ongoing weed control. However, it's very important to know that metribuzin can be harmful to the environment, especially to water sources, and it can damage or kill many other crops, so you must only use it on crops that are specifically listed on the label. Also, metribuzin can stay in the soil for a long time and can affect crops that you plant later in the same field. You must wait the required number of days (usually 30-60 days or more) after application before planting other crops in the same field. Always follow the label instructions very carefully and wear protective clothing when using this product.
