Glean 75 DF is a selective, systemic herbicide containing 75% Chlorsulfuron as its active ingredient. It is primarily used to control broad-leaved weeds and select grasses in wheat (pre- and post-emergence) and barley or oats (post-emergence). It is valued for its long-lasting residual action.
Active Ingredient: 75% Chlorsulfuron
Mode of Action: It acts as both a pre-emergence and early post-emergence herbicide. It inhibits the plant's ability to synthesize certain enzymes, which stops amino acid production and weed growth.
Application Guidelines:
- Target Crops: Wheat (winter/spring), barley, and oats.
- Application Method: Can be applied either as a pre-emergent (after planting, before the crop emerges) or as an early post-emergent spray (when crops are actively growing).
- Standard Rate: Generally applied at 15 - 20 grams per hectare (0.25 - 0.35 oz per acre) depending on the weed spectrum.
- Optimal Conditions: Best results occur when applied to small, actively growing weeds (less than 5 cm tall or across) and moist soil.
Usage:
Pre-Emergence: Apply after planting but before the crop emerges to stop weeds before their seeds germinate.
Post-Emergence: Apply when the weeds and crops (typically at the 2-leaf stage) are actively growing.
Safety Warning: Do not use pre-emergence on barley crops
Benefits:
Selective Weed Control: It targets invasive broadleaf weeds while keeping cereal crops completely safe and unharmed.
Dual Application Timing: It is highly flexible and can be applied pre-emergence (before weeds sprout) or post-emergence (after weeds appear).
Long-Lasting Residual Action: Beyond killing actively growing weeds, it remains active in the soil to suppress late-emerging weeds, keeping fields clean for months.
Ultra-Low Dosage: Requires only grams per acre instead of kilograms, making the product much easier to transport, store, and mix.
Systemic Effectiveness: The product is quickly absorbed by both the roots and foliage, causing weed growth to stop within hours of application.
