Introduction:
Glyphosate is a widely used herbicide that is commonly used to kill weeds and grasses. It has both agricultural and non-agricultural applications. However, there are concerns about its potential environmental impact, particularly its persistence in the environment and its potential to leach into groundwater.
Statement 1: Glyphosate is a widely used herbicide that can kill certain weeds and grasses.
This statement is correct. Glyphosate is one of the most widely used herbicides in the world. It is primarily used to kill unwanted plants, including weeds and grasses. It is effective in controlling a wide range of plant species and is used in agricultural, residential, and industrial settings.
Statement 2: Glyphosate is not biodegradable and results in leaching into groundwater.
This statement is incorrect. Glyphosate is actually biodegradable, meaning that it can be broken down by natural processes over time. However, it is important to note that the degradation rate of glyphosate can vary depending on environmental conditions such as temperature, pH, and soil type.
While glyphosate is biodegradable, there have been concerns about its potential to leach into groundwater. Leaching refers to the movement of substances through soil and into groundwater. Studies have shown that glyphosate can leach into groundwater under certain conditions, particularly in areas with sandy soils and shallow water tables. However, the extent of leaching can also depend on factors such as application rate, timing, and soil characteristics.
Conclusion:
In conclusion, the correct statement is Statement 1: Glyphosate is a widely used herbicide that can kill certain weeds and grasses. Statement 2 is incorrect as glyphosate is biodegradable, although there are concerns about its potential to leach into groundwater under certain conditions.

Experts have recently warned pesticide sellers against the sale and storage of glyphosate as its exposure is known to cause cancer.
About Glyphosate:
- Glyphosate is a widely used herbicide that can kill certain weeds and grasses.
- The product is used primarily in agriculture but also in forestry and lawn and garden care.
- Glyphosate is a small molecule made of a linear carbon chain with weaker bonds, which makes glyphosate less persistent in the environment.
- In India, it goes by various brand names, including Roundup, Glycel, and Brake.
- Herbicidal Action:
- Glyphosate works by inhibiting an enzyme called EPSP synthase, which is essential for the synthesis of certain amino acids that plants need for growth.
- By disrupting this enzyme, glyphosate interferes with the plant's ability to produce proteins, leading to the eventual death of the plant.
- Broad-Spectrum:
- Glyphosate is considered a broad-spectrum herbicide, meaning it can effectively control a wide variety of plants, including grasses, broadleaf plants, and woody plants.
- It is effective only on plants that grow above the water. It will not be effective on plants that are submerged or have most of their foliage underwater, nor will it control regrowth from seed.
- Systemic Nature:
- Glyphosate is a systemic herbicide, which means it is absorbed by the plant's leaves and then translocated throughout the plant's vascular system.
- This allows it to reach various parts of the plant, including the roots, leading to effective control of both above-ground and below-ground plant parts.
- Glyphosate is degraded in soil and water by microbesand binds tightly to soil particles, which prevents the leaching of glyphosate into groundwater.
- Glyphosate does not degrade quickly in plants. As a result, it is possible that glyphosate residues can occur in food products.
Hence only statement 1 is correct.
