Trigger VG

Technical performance of "Trigger WG": How tribenuron-methyl works

The efficacy of "Trigger WG" relies on the inhibition of the acetolactate synthase (ALS) enzyme. Unlike contact-based solutions, this systemic herbicide from Adama Agan Ltd. (Israel) penetrates the weed's foliage and moves through the plant, arresting cell division in meristematic tissues. Within hours of application, sensitive weed species cease their competition for moisture and soil nutrients with the host cereal crops.

Why formulation and selectivity matter

The water-dispersible granule (WG) formulation ensures consistent tank-mix stability and eliminates dust handling issues. A major technical advantage is the high selectivity of the herbicide: cereal crops like wheat and barley rapidly metabolize the tribenuron-methyl into non-toxic components, while broadleaf weeds such as amaranth, ragweed, and cleavers lack this protective mechanism and perish shortly after exposure. With usage rates as low as 20–50 grams per hectare, it provides a cost-effective solution for large-scale farming.

Application and Field Practicality

• Systemic Control: While full necrosis of weeds typically takes 7–10 days, growth inhibition occurs immediately, providing a critical buffer for the crop during its early development.
• Versatility: The product is highly effective against key broadleaf weeds like shepherd’s purse and field mustard, and remains active even in cooler temperatures (starting at +5°C), making it a prime choice for early spring weed management.
• Precision: Registered for one application per season, the timing should be carefully aligned with the crop’s vegetative stage—from the two-leaf stage up to the start of stem elongation.

By integrating "Trigger WG" into a crop protection program, producers benefit from Israeli formulation expertise, ensuring rapid absorption and reliability even under variable environmental conditions.
