DIAGONAL

Systemic weed control: «Diagonal» herbicide

In modern intensive farming, soil protection is the cornerstone of crop productivity. «Diagonal», developed by Shandong Zhangmi Pesticide Co., Ltd. (China), is a systemic herbicide based on acetochlor. It is a strategic choice for growers focusing on suppressing weed competition before the crop even establishes itself.

Technical profile and selectivity

As a selective soil-applied herbicide, «Diagonal» (emulsifiable concentrate) is specifically designed for sunflower and corn crops. Its main task is to inhibit the growth of annual grasses and broad-leaved weeds at the germination stage. Acetochlor disrupts protein synthesis and cell division in meristems, leaving weeds vulnerable as they push through the treated soil layer.

• Type: Systemic, selective herbicide.
• Application rate: 1.5–3 L/ha (depending on soil type and weed pressure).
• Timing: Pre-emergence, single application per season.

The manufacturer, Shandong Zhangmi Pesticide Co., Ltd., focuses on delivering consistent active ingredient performance, allowing «Diagonal» to fit well into cost-effective crop protection programs. Given its Class 2 hazard rating, strict adherence to safety protocols during handling and application is mandatory.

Effective application strategy

For maximum performance, «Diagonal» requires a well-prepared seedbed. The efficacy of acetochlor is closely linked to soil moisture levels. Therefore, the optimal window for application is immediately after planting, before the crop emerges. When incorporated properly or activated by rainfall, «Diagonal» forms a reliable «protective screen,» ensuring that corn and sunflower crops start their cycle without competing for moisture and nutrients.
