Lemur, EC, herbicide

Selectivity Mechanism and Performance of Lemur, EC

The herbicide Lemur, EC by Nertus is based on the active ingredient quizalofop-P-tefuryl, which ensures high systemic activity. As a selective post-emergence herbicide, this product is engineered specifically to control grass weeds in broad-leaved crops, including vegetables and industrial crops (onions, sugar beets, winter rapeseed, sunflower, etc.).

Biochemical Action

Quizalofop-P-tefuryl is rapidly absorbed through the leaf surface and translocated throughout the plant (systemic action), accumulating in the meristematic growth zones. The compound inhibits the synthesis of fatty acids, which halts cell division and leads to the inevitable death of the weed. Critically, the herbicide exhibits high selectivity, meaning it effectively eliminates quackgrass (Elytrigia repens), wild oats, barnyard grass, and green foxtail without harming the cultivated plants.

Application Guidelines and Technical Specifications

• Growth Stage: Optimal performance is achieved when applying the product to actively growing weeds (at the 2- to 4-leaf stage for annuals).
• Dosage: The technical guidelines specify an application rate of 1.0 to 2.0 liters per hectare, depending on weed infestation levels and species composition.
• Frequency: The herbicide is designed for a single application per season.
• Safety: Classified as a Hazard Class 2 substance, requiring strict adherence to safety protocols when handling emulsifiable concentrates.

The emulsifiable concentrate formulation enhances rapid penetration into weed tissues, and the systemic mode of action allows the product to maintain efficacy under varying environmental conditions, provided they do not inhibit plant metabolism. This Nertus solution is a robust tool for clearing fields of grass-type competitors, ensuring that crops have maximum access to soil nutrients and space for development.
