Francon, CS, herbicide

Why Frankorn became a staple for corn protection

When you step into a field where corn is struggling against ragweed or velvetleaf, you realize that half-measures just don't cut it. Frankorn, SC from Frandesa is the kind of tool that does the job right. It is a systemic post-emergence herbicide, and its main advantage is that it attacks weeds from within, blocking their development almost immediately after application.

Application experience and dosage logic

In practice, we typically work with a rate of 0.5–1.0 L/ha, depending on how heavy the weed infestation is and the growth stage of the weeds. The product is selective: corn tolerates it well, while a wide range of broadleaf weeds (from lambsquarters and pigweed to shepherd's purse) stop competing with the crop for light and moisture. Keep in mind: this is a post-emergence herbicide. Spray the foliage when weeds are actively growing to get the fastest results.

Practical tips

• Systemic action: The mesotrione ingredient is reliable. It penetrates deeply, meaning that even if some weeds were partially covered by leaves, the product will still reach them.
• Ease of use: The suspension concentrate formula mixes easily and doesn't clog sprayer nozzles, which saves a lot of time during tank filling.
• Safety: Given its Hazard Class 2, always wear proper PPE when handling. Also, don't try to double-up on treatments; the guidelines specify a maximum of one application per season.

Frankorn is the choice for the agronomist who needs to clean a field of problematic broadleaf weeds in a single pass. A workhorse for those who value efficiency and cost-effectiveness.
