Introduction

Noweed Herbicide (Glyphosate 41% SL) is a non-selective, systemic herbicide formulated as a soluble concentrate (SL) containing 41% glyphosate, an organophosphate herbicide that acts as an inhibitor of the shikimate pathway in plants. By disrupting the shikimate pathway, glyphosate prevents the synthesis of essential aromatic amino acids, leading to protein starvation and plant death.

Active Ingredient and Mode of Action

The active ingredient in Noweed Herbicide, glyphosate, is a synthetic organophosphate herbicide that mimics the natural plant metabolite shikimic acid. When absorbed by susceptible plants, glyphosate binds to the enzyme 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase, an essential enzyme in the shikimate pathway. The shikimate pathway is responsible for the synthesis of aromatic amino acids, including tyrosine, tryptophan, and phenylalanine, which are essential components of proteins.

By inhibiting EPSP synthase, glyphosate disrupts the shikimate pathway, preventing the synthesis of aromatic amino acids and leading to protein starvation. This disruption manifests as chlorosis (yellowing) and necrosis (tissue death) of plant tissues, eventually leading to plant death.

Application Methods

Noweed Herbicide can be applied as a foliar spray, soil drench, or directed spray, depending on the target weed and application area.

• Foliar spray: Mix the recommended dosage of Noweed Herbicide with water and apply it to the leaves of weeds until they are thoroughly wet.

• Soil drench: Mix the recommended dosage of Noweed Herbicide with water and apply it to the soil around the base of weeds.

• Directed spray: For woody plants and hard-to-control weeds, use a directed spray to target specific areas of the plant, such as the stem or basal foliage.

Dosage Rates

The recommended dosage rate of Noweed Herbicide varies depending on the target weed, application method, and water volume. Consult the product label for specific dosage instructions.

Precautions

When handling and applying Noweed Herbicide, follow these precautionary measures to ensure safety:

• Wear protective clothing, including gloves, goggles, and a respirator.

• Avoid contact with skin and eyes.

• Do not apply the herbicide in windy conditions.

• Wash hands thoroughly after handling the product.

• Dispose of empty containers responsibly.

• Avoid using near water sources or aquatic habitats.

• Do not use on bees or other beneficial insects.

Storage and Shelf Life

Store Noweed Herbicide in a cool, dry place, away from direct sunlight and heat. When stored properly, the product has a shelf life of two years.

Conclusion

Noweed Herbicide (Glyphosate 41% SL) is a powerful and effective non-selective herbicide that provides broad-spectrum control of a wide range of weeds in various non-crop and pre-harvest desiccation applications. Its systemic action, rapid knockdown effect, and favorable environmental profile make it a popular choice for weed control. However, it is crucial to use Noweed Herbicide responsibly and in accordance with label instructions due to its non-selective nature and potential risks to non-target organisms and the environment.
