Perun

Mechanism of Action and Selectivity

The «Perun» herbicide from «Agricopter Asia Limited» is formulated with prometryn, a triazine compound that acts as a robust soil-applied barrier. Its primary technical advantage lies in its systemic activity: by inhibiting the Hill reaction in susceptible weeds, it disrupts their photosynthetic processes. Because it is provided in an emulsifiable concentrate form, it ensures superior spread and retention within the soil matrix, delivering a targeted control effect before weeds even reach the surface.

Technical Application Guidelines

As a selective, pre-emergence herbicide, «Perun» offers a strategic solution for managing weed competition in sensitive crops.

• Soil Activity: The product effectively establishes a protection zone in the upper soil layer, targeting annual dicots and grasses at the point of germination.
• Formulation Quality: The concentrate emulsification allows for precise application at the recommended rate of 2–4 L/ha, ensuring even distribution across the field surface.
• Crop Compatibility: «Perun» is engineered for selective usage on crops such as carrots, garlic, coriander, peas, beans, and sunflowers. These plants are capable of metabolizing the active ingredient, making it safe for selective weed management.

Field performance is highly dependent on sufficient soil moisture for the activation of the compound. Falling under toxicity class 3, standard handling safety protocols are required during application. The limitation of one application per season is a critical design feature intended to manage environmental load and prevent soil residue buildup that could impact future crop rotation cycles. By suppressing competition at the early stages of development, the product provides a significant technical advantage for yield preservation.
