Product Overview

Atrazine 50% WP (Crozin) is a selective pre-emergence herbicide commonly used to control a wide range of broadleaf and grassy weeds in maize, sorghum, and sugarcane crops. It is a triazine herbicide that works by inhibiting photosynthesis in susceptible weeds. Atrazine is a highly effective herbicide that has been used for decades to control weeds in agricultural settings.

Active Ingredients

The active ingredient in Atrazine 50% WP (Crozin) is atrazine, which is a triazine herbicide. Atrazine is a white, odorless, and crystalline solid with a molecular formula of C2H5ClN5.

Mode of Action

Atrazine works by inhibiting photosynthesis in susceptible weeds. It does this by binding to a protein complex in the chloroplast, which is responsible for light-dependent reactions in photosynthesis. When atrazine binds to this protein complex, it blocks electron transport, which prevents the production of ATP and NADPH, which are essential for photosynthesis. As a result, atrazine-treated weeds are unable to produce the energy they need to survive, and they eventually die.

Application Methods

Atrazine 50% WP (Crozin) can be applied either as a pre-emergence or early post-emergence herbicide. For pre-emergence application, the herbicide should be applied to the soil surface after planting the crop but before the weeds emerge. For early post-emergence application, the herbicide should be applied to the soil surface after the weeds have emerged but before they reach the four-leaf stage.

Restrictions

Atrazine 50% WP (Crozin) should not be applied to crops that are grown on sandy soils or soils with high organic matter content. It should also not be applied to crops that are under water stress.

Precautions

Atrazine 50% WP (Crozin) is a restricted-use herbicide, which means that it can only be applied by certified applicators. It is important to wear protective clothing, such as gloves, goggles, and a respirator, when handling and applying the herbicide. Atrazine 50% WP (Crozin) is toxic to fish and other aquatic organisms, so it should not be applied near water sources.

Storage and Disposal

Atrazine 50% WP (Crozin) should be stored in a cool, dry place out of reach of children and pets. The herbicide should not be stored for more than one year. Empty containers should be rinsed three times with water and disposed of according to local regulations.

Additional Notes

Atrazine is a persistent herbicide that can remain in the soil for several years. It is important to follow the recommended application rates and application methods to minimize the risk of environmental contamination. Atrazine is also a potential groundwater contaminant, so it should not be applied in areas where groundwater is used for drinking water.
