Progard, CS, herbicide

Mechanism of Action and Selectivity

The Progard, SC (Suspension Concentrate) herbicide is formulated with prometryn, a compound that exerts systemic control over weed emergence. As a soil-applied herbicide, it inhibits the photosynthetic process (Hill reaction) in germinating weeds. Its systemic effect allows for uptake through both the root system and developing shoots, creating a vital chemical barrier within the top layer of the soil.

Technical Application Details

The SC formulation ensures a uniform distribution of the active ingredient during spraying. Classified as a selective soil-applied herbicide, it is designed strictly for pre-emergence application. Adhering to the specific dosage—ranging from 1.0 to 3.0+ liters per hectare—is critical and depends on the soil texture and weed pressure. Because of its selective nature, Progard does not inhibit the development of crops such as carrots, potatoes, coriander, or sunflower, provided it is applied before the crop emerges.

Key Advantages for Agrotechnology

• Broad Spectrum Control: Effectively suppresses annual broad-leaved and grass weeds that typically compete with crops during early developmental stages.
• Residual Efficacy: The prometryn-based composition provides a long-lasting protective window, ensuring the crop has a weed-free start to the season.
• Soil Adaptability: The flexible application rates allow for optimization based on varying soil types, from sandy loams to heavy chernozems.

Manufactured by Rangoli, this herbicide is classified under hazard class 3, requiring standard safety precautions during handling. A single seasonal treatment, applied at the correct growth stage, effectively mitigates weed competition, allowing the crop to develop without the stress of nutrient or sunlight scarcity caused by invasive vegetation.
