Lobera

Chemical Mechanism for Grass Weed Control

The herbicide "Lobera" is based on the active ingredient quizalofop-P-ethyl, a member of the aryloxyphenoxypropionate group. Unlike non-selective herbicides, this formulation acts as a highly selective tool. Technically, the mechanism involves inhibiting the enzyme acetyl-CoA carboxylase, which is responsible for fatty acid synthesis in grass cells. The result is a total cessation of growth in weed meristematic tissues within hours of absorption through the leaf surface.

Formulation Architecture and Systemic Action

"Lobera" is produced as an emulsifiable concentrate, ensuring optimal adhesion to the waxy layer of weed leaves. Due to its systemic nature, the active ingredient quickly translocates via the phloem and xylem, reaching growth points, including the rhizomes of quackgrass. This is critical for preventing the secondary regrowth of rhizomatous weeds.

Operational Guidelines

• Crop Selectivity: The product exhibits high selectivity, allowing use on sugar beets, oilseed rape, soybeans, sunflowers, and flax without the risk of phytotoxicity to the primary crop.
• Application Standards: The application rate ranges from 0.5 to 1.2 L/ha. It is important to note that maximum efficacy is achieved with a single application. A pre-harvest interval of at least 30 days must be observed after treatment.
• Efficacy: The product is designed to eliminate both annual and perennial grass species, functioning effectively as a post-emergence rescue herbicide.

The production cycle of the herbicide combines the capabilities of Zhejiang Hisun Chemical Co., Ltd. (China) and the manufacturing facilities of the Bila Tserkva Plant of Preparative Forms (Ukraine), ensuring formulation stability while adhering to a Class 3 toxicity rating.
