Product Overview

STIGMA (Nichino Chemical India) Imazapyr 10% SL is a non-selective herbicide commonly used to control a wide range of annual and perennial grasses, broadleaf weeds, and woody plants in various settings, including non-crop areas, industrial sites, and rights-of-way. It is an imidazolinone herbicide that works by inhibiting the enzyme EPSP synthase, which is essential for the synthesis of aromatic amino acids in plants. Without aromatic amino acids, plants cannot synthesize proteins, and they eventually die. STIGMA is a highly effective herbicide that provides long-term residual control of a broad spectrum of weeds.

Active Ingredient

The active ingredient in STIGMA (Nichino Chemical India) Imazapyr 10% SL is imazapyr, which is an imidazolinone herbicide. It is a yellow, odorless, and viscous liquid with a molecular formula of C13H12CIN3O3.

Mode of Action

STIGMA (Nichino Chemical India) Imazapyr 10% SL works by inhibiting the enzyme EPSP synthase, which is essential for the synthesis of aromatic amino acids in plants. Aromatic amino acids are essential components of proteins, and their inhibition disrupts protein synthesis, leading to the death of the plant.

Application Rates

The application rate of STIGMA (Nichino Chemical India) Imazapyr 10% SL depends on the type of vegetation being controlled and the application method. The recommended application rate for non-crop areas, industrial sites, and rights-of-way is 0.4 to 1.2 kilograms per hectare (0.36 to 1.08 pounds per acre).

Application Methods

STIGMA (Nichino Chemical India) Imazapyr 10% SL can be applied by either foliar or basal application. Foliar application is the most common method, and it involves spraying the herbicide onto the foliage of the target vegetation. Basal application involves applying the herbicide to the base of the target vegetation, such as the trunk or stems.

Restrictions

STIGMA (Nichino Chemical India) Imazapyr 10% SL should not be applied to areas where desirable vegetation is present. It should also not be applied to areas where there is potential for runoff into water sources.

Precautions

STIGMA (Nichino Chemical India) Imazapyr 10% SL is a moderately toxic herbicide, so it is important to wear protective clothing, such as gloves, goggles, and a respirator, when handling and applying the herbicide. STIGMA (Nichino Chemical India) Imazapyr 10% SL is moderately toxic to fish and other aquatic organisms, so it should not be applied near water sources.

Storage and Disposal

STIGMA (Nichino Chemical India) Imazapyr 10% SL 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

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