Targon-S

Mechanism of Action and Selectivity of «Targon-S»

The active ingredient of this product is quizalofop-P-ethyl, belonging to the aryloxyphenoxypropionate chemical class. It is a systemic herbicide that is rapidly absorbed by the foliage of weeds and translocated via the xylem and phloem to the growth points. A key feature of the formulation developed by Shandong Binnong Technology is its high selectivity. Unlike non-selective herbicides, the molecules of «Targon-S» inhibit lipid synthesis exclusively in grass weeds, leaving crops like sunflower, soybean, rapeseed, and flax unharmed. Weed growth stops 24–48 hours after application, with complete mortality occurring within 10–14 days.

Application and Technical Nuances

• Formulation: The emulsifiable concentrate allows the product to effectively adhere to the leaf surface, penetrating the waxy cuticle of difficult weeds such as couch grass, barnyard grass, and wild oats.
• Timing: As a post-emergence herbicide, «Targon-S» must be applied during the active growth phase of weeds (from 2 to 4 leaves). A single application at a rate of 0.5 to 2 L/ha provides maximum control of weed infestation without the need for follow-up spraying.
• Safety Profile: The product is classified as Toxicity Class 3. It is reliable under standard operating procedures but requires strict adherence to temperature guidelines and the avoidance of stress conditions for the main crop.

The systemic nature of the herbicide prevents the regrowth of rhizomatous weeds, making «Targon-S» an essential tool in intensive production systems for oilseeds and industrial crops, where keeping fields clean during early vegetative stages is paramount.
