Goltix 70

Metamitron: The Biochemistry of Selectivity

The core of "Goltix 70" by Makhteshim Agan is the active ingredient metamitron (700 g/kg as a suspension concentrate). Belonging to the triazine class, its mechanism of action involves the inhibition of photosynthesis by blocking electron transport in photosystem II. The primary value for sugar beet and fodder beet growers lies in its high selectivity. The crop metabolizes metamitron significantly faster than weeds, allowing for application without phytotoxic risks to the sprouts.

Versatility: From Soil to Foliage

The technological flexibility of "Goltix 70" is provided by its dual mode of action:

• Soil Control: By creating a protective screen in the upper soil layer, it prevents the germination of common lambsquarters and other annual broadleaf weeds. Effectiveness is highly dependent on soil moisture; higher levels facilitate quicker uptake by weeds.
• Foliar (Post-emergence) Action: When applied during the vegetative stage, the preparation penetrates the leaf surface and is systemically distributed through plant tissues. This is critical if the pre-emergence window has been missed.

Operational Best Practices

The maximum allowed number of applications is 3 per season. Dosage variation from 2.0 to over 3.0 L/ha allows for precise adjustment based on weed spectrum and crop development stage. A vital technical note: utilizing systemic action requires high-quality spray coverage. When working against emerged weeds, the growth stage is essential—maximum vulnerability in species like lambsquarters occurs at the cotyledon phase, so delaying application significantly reduces biological efficacy. As a selective tool, "Goltix 70" serves as an ideal component for tank mixes, effectively complementing contact-type herbicides.
