Professional Weed Control for Key Field Crops

"Shtarga," manufactured by DDE Farm AG (Liechtenstein), is a systemic selective herbicide engineered to target graminaceous weeds in essential crops such as soybeans, sunflowers, oilseed rape, sugar beets, and flax. In agricultural practice, it acts as a reliable insurance policy against heavy infestations of both annual and perennial grasses, including the notoriously difficult couch grass (Elymus repens).

How It Operates

The active ingredient, Quizalofop-P-ethyl, belongs to the aryloxyphenoxypropionate class. It works through systemic action: the herbicide is absorbed by the foliage and translocated to the growing points of the weeds. This halts plant development within hours of application, followed by total necrosis within 7–14 days. Because it is highly selective, it allows the crop to continue its development without the stress caused by competitive weed growth.

Key Application Guidelines

• Application Strategy: Designed for post-emergence application. For best results, target annual grasses at the 2–4 leaf stage, and perennial grasses when they reach 10–15 cm in height.
• Flexible Dosage: The application rate ranges from 0.4 to 1.2 L/ha, allowing for adjustments based on the specific weed pressure in your fields.
• Systemic Efficacy: Being a foliar-applied herbicide, it is perfectly suited for insurance treatments, hitting target weeds while sparing the crop canopy.
• Safety and Restrictions: Classified under hazard class 3, the product is safe when used according to regulations. Always maintain the 30-day pre-harvest interval before proceeding to crop collection.

For farm managers, "Shtarga" offers a streamlined approach to weed management, eliminating the need for mechanical weeding and saving valuable soil moisture. It ensures that nutrients intended for your crops are not hijacked by invasive grasses.
