ANTIGROSS-ZORIA, KE

Mechanism of Action and Selectivity

«ANTIGRASS-ZORYA, CE» is based on the active ingredient quizalofop-P-ethyl, belonging to the aryloxyphenoxypropionate class. Unlike non-selective herbicides, this product operates systemically and selectively. Upon contact with the vegetative mass of grass weeds, quizalofop-P-ethyl is rapidly absorbed by the leaves and translocated to the points of active growth — the meristematic tissues of roots and shoots. By inhibiting lipid synthesis, the herbicide halts cell division, making the weed's recovery impossible.

Practical Implications

The systemic action of «ANTIGRASS-ZORYA, CE» ensures the eradication of both the above-ground part and the root system of perennial grasses, such as couch grass (Elymus repens). For an agronomist, this means no re-growth, which is critical when cultivating soy, sunflower, flax, or potatoes. As the product is selective, broad-leaved crops remain resistant to the active ingredient, allowing for post-emergence application without the risk of phytotoxicity.

• Formulation: An emulsifiable concentrate ensures rapid solubility and uniform distribution across the leaf surface.
• Application Method: A post-emergence foliar herbicide, the effectiveness of which depends on the active growth phase of the weeds.
• Safety Profile: Classified as Toxicity Class 3, it requires adherence to application guidelines while providing predictable control of grass components in crops.

The efficiency of the application is directly correlated with the weed growth stage: optimal results are achieved when treating annual species in the 2-4 leaf stage and when couch grass is between 10-15 cm in height. The systemic nature of the product allows it to reach hidden tillering nodes, making «ANTIGRASS-ZORYA, CE» a reliable tool for preserving yield potential in high-infestation conditions.
