Glufosinate Ammonium
Description
Glufosinate ammonium is a non-selective contact herbicide that kills weeds very quickly when sprayed on them. The word 'non-selective' means it will kill any plant it touches, including your crops, so you must be very careful when using it. The word 'contact' means it works by direct contact with the plant - it doesn't move through the plant like systemic herbicides do. When you spray glufosinate ammonium on weeds, you'll see them start to turn brown and die within a few days. It works especially well on annual and perennial broadleaf weeds and grasses. Glufosinate ammonium is very useful for clearing weeds before planting your crops, or for controlling weeds in areas where you don't want any plants to grow, like around farm buildings, along fences, or in pathways. It's also used in some genetically modified crops that are resistant to it. One of the advantages of glufosinate ammonium compared to some other non-selective herbicides is that it breaks down relatively quickly in the soil, so it doesn't stay active for a long time. However, it's very important to know that glufosinate ammonium will kill or damage any plant it touches, so you must never spray it on or near your growing crops unless you're using it on crops that are specifically resistant to it. Also, you need to be careful about drift - if the spray drifts onto your crops, it can cause serious damage. Always spray when the weather is calm, and be very careful not to let the spray drift to areas where you have plants growing. You can only use it before planting or after harvesting - never when your crops are growing (unless using resistant varieties). Always follow the label instructions and wear protective clothing when using this product.
