Product Overview

Lawadin (CROP LIFE SCIENCE LTD.) Imazethapyr 10% SL is a selective post-emergence herbicide that effectively controls a wide range of annual broadleaf weeds and grasses in various crops, including rice, soybeans, and peanuts. It is known for its broad-spectrum activity, long residual activity, and favorable crop safety profile.

Active Ingredient

Lawadin's active ingredient is imazethapyr, an imidazolinone herbicide that inhibits the enzyme acetohydroxy acid synthase (AHAS) in susceptible plant species. AHAS plays a crucial role in branched-chain amino acid (BCAA) biosynthesis, essential for plant growth and development. Disruption of AHAS by imazethapyr leads to the accumulation of toxic metabolites, ultimately causing plant stunting and eventual death.

Mode of Action

Lawadin acts as a post-emergence herbicide, meaning it is most effective when applied to actively growing weeds and grasses. It is absorbed through the leaves and roots of plants and quickly translocates throughout the plant, disrupting AHAS activity and causing the accumulation of toxic metabolites, leading to plant stunting and eventual death.

Application Methods

Lawadin can be applied using various methods, including:

• Broadcast spraying: This involves applying the herbicide uniformly over the entire field using a boom sprayer or aerial application.
• Spot spraying: This method involves applying the herbicide directly to individual weed or grass clumps or problem areas, reducing herbicide use and potential environmental impact.
• Directed spraying: This method involves applying the herbicide directly to the base of trees, shrubs, or vines to control unwanted vegetation.

Application Rates

The application rate of Lawadin varies depending on the target weed or grass species, crop type, and soil conditions. Generally, application rates range from 40 to 120 grams of product per hectare (g/ha).

Residual Activity

Lawadin has a moderate residual activity, typically lasting for several weeks or months, depending on soil conditions and weather patterns. This provides effective weed and grass control throughout the growing season, reducing the need for multiple herbicide applications.

Crop Safety

Lawadin is considered safe for use on a wide range of crops, including rice, soybeans, and peanuts. However, it is important to follow label directions and consult with local experts to ensure crop compatibility.

Environmental Considerations

Lawadin is considered to have a relatively low environmental impact compared to other herbicides. It has a low mobility in soil, reducing the risk of leaching into groundwater. Additionally, imazethapyr is not persistent in the environment, breaking down over time into non-toxic compounds.

Safety Precautions

Lawadin is a moderately toxic herbicide, and it is crucial to follow all safety precautions when handling and applying the product. Personal protective equipment (PPE), including gloves, goggles, and a respirator, should be worn when mixing, loading, and applying the herbicide. Avoid contact with skin and eyes, and wash thoroughly after handling.

Storage and Disposal

Store Lawadin in a cool, dry place, out of reach of children and pets. Dispose of unused herbicide and empty containers according to local regulations.
