Calibre 75

Field Experience: Why Caliber 75 is a Reliable Choice for Cereal Protection

When it comes to protecting winter wheat, barley, or rye, timing and reliability are everything. Based on my field experience with DuPont's Caliber 75, this systemic herbicide has become a standard in my weed management program. It is highly effective at controlling stubborn weeds without causing unnecessary stress to the crop.

How it performs

The synergy between thifensulfuron-methyl and tribenuron-methyl makes this product a powerful tool. It is particularly impressive against aggressive weeds like Cirsium arvense (field thistle) and Chenopodium album (fat-hen). Once applied, the systemic action kicks in almost immediately, stopping weed growth at the root level.

Operating advantages

• Efficiency in application: The water-dispersible granules dissolve flawlessly, ensuring your sprayer nozzles stay clean and free of sediment, which is a major time-saver during busy spraying seasons.
• Logistical ease: With a dosage of up to 25 grams per hectare, storage and handling are incredibly convenient compared to bulkier liquid herbicides.
• Post-emergence flexibility: As a selective herbicide, it allows for a wide window of application, meaning I can hit the fields when the timing is perfect for the crop's development stage.

Practical tips

One of the best aspects is the single-treatment requirement per season. With a pre-harvest interval of just one day, it provides great flexibility for scheduling harvest operations. In my practice, the key is to apply Caliber 75 while the weeds are still in their early growth stages to maximize its selectivity and potency. For any producer looking for a clean field and high yield potential, this DuPont solution is a trustworthy and efficient ally.
