Sachara, EC, herbicide

An effective soil barrier for corn and sunflower

"Sahara, KE" by Defenda is a selective systemic herbicide based on acetochlor (emulsifiable concentrate), which shifts weed control from post-emergence salvage to preventative protection. Its technical value lies in creating a stable protective screen in the topsoil layer, neutralizing threats even before weeds germinate.

Mechanism of action: targeting cellular processes

The active ingredient, acetochlor, belongs to the chloroacetamide group. Its primary function is to block protein synthesis and suppress the growth of meristematic tissues in weed seedlings. Due to its systemic nature, the product is absorbed by the coleoptile (in grasses) and hypocotyl (in broad-leaved weeds). Consequently, weed growth stops at early stages, even before the seedlings emerge on the soil surface.

Technological aspects of application

• Formulation: The emulsifiable concentrate ensures high stability of the spray solution and optimal distribution across the soil surface, which is critical for forming a continuous protective barrier.
• Control Spectrum: The herbicide shows high efficacy against most annual grasses and broad-leaved weeds that typically compete with corn and sunflower for moisture and nutrients during the critical initial vegetation period.
• Application method: As a typical soil-applied herbicide, "Sahara, KE" should be applied before, during, or immediately after planting, but prior to crop emergence.

The application rate ranges from 1.0 to 2.0 L/ha, depending on soil type and weed pressure. A crucial technological requirement for maximum efficacy is sufficient soil moisture at the time of application, as moisture activates the herbicide screen and ensures its uniform fixation within the soil profile.

By adhering to the application guidelines (one treatment per season), "Sahara, KE" eliminates weed competition during the most vulnerable growth phases of sunflower and corn, preserving the yield potential inherent in the seeds.
