Why "Diagonal, EC" is the choice for soybean and sunflower protection

When the machinery hits the field for pre-emergence treatment, an agronomist gets exactly one chance to create a reliable protective barrier. The Chinese product "Diagonal, EC" by Shandong Zhongshi Pesticide is a classic soil-applied tool based on acetochlor, which has proven its effectiveness against stubborn annual grasses and broad-leaved weeds for years.

Operating and application features

As an operator, I value predictability. This systemic herbicide works on a "apply and forget" principle, provided the technology is strictly followed. Acetochlor forms a protective "screen" in the topsoil layer, blocking weed germination in the early stages.

• The application rate (1.5–3 L/ha) allows for flexibility depending on soil type: use the minimum for light sandy soils and shift toward the upper limit for heavy chernozems.
• The product is selective; when incorporated properly, crops like soybeans, corn, or sunflowers face minimal stress.
• The emulsifiable concentrate mixes easily with water and does not clog sprayer nozzles, which is critical during high-volume operations.

Key considerations

"Diagonal" is classified as a category 3 hazard, so standard protective measures when handling concentrated emulsions are essential. A single seasonal application is sufficient to relieve competitive pressure during the crop's early development stage. Remember: this herbicide is a team player. Its performance depends directly on soil moisture and the quality of seedbed preparation; clods of earth in the field are the primary enemies of uniform coverage. If soil moisture is low, effectiveness may decrease, which is why many farms prefer applying it before rainfall or under irrigation.
