HERBICide DEFENDA PERUN

Mechanism of Action

PERUN is a herbicide of the selective action. The preparation is absorbed by both sprouts, and roots of sprouting weeds when applying the preparation to their sprouts. PERUN impacts on the sprouting weeds through the leaves. The effectiveness of the preparation is achieved due to the ability of the active substance of the preparation (promethrin) to block the process of photosynthesis in weed plants.

Preparation Properties

Application of a herbicide significantly reduces the adverse effects of weeds in the early, most critical period for the culture. It destroys weeds at the time of their germination or within 5-7 days when it is applied post-emergence. The long protective period lasts 10-12 weeks (depending on the weather conditions). It is not phytotoxic to the culture in compliance with the rules of application. It does not affect the following cultures in crop rotation.
