Grand Guard EC + PAR 'Corona'

Advanced weed control for sensitive crops

The «Oberig Grand» herbicide, complemented by the «Korona» surfactant (PAR), is a specialized solution designed to combat a broad spectrum of grass weeds. Featuring clethodim as its active ingredient, this product is a staple in modern intensive farming. Developed by the manufacturer «Zhenjiang Agrin Company Ltd.», this herbicide offers precision, allowing farmers to clear fields of couch grass, wild oats, and foxtail without harming the sensitive crops being cultivated.

Mechanism and Systemic Protection

The systemic action of clethodim ensures rapid penetration through the leaf surface directly into the weed's vascular system. By targeting the growth points, the herbicide effectively halts development, making it an essential tool for post-emergence crop protection. The included «Korona» surfactant enhances adherence, ensuring the active ingredients penetrate effectively even in adverse weather conditions or on difficult-to-wet leaf surfaces.

Target Crops and Application

Due to its selective (discriminatory) nature, this herbicide is widely used across various agricultural sectors:

• Oilseeds: sunflower, winter rapeseed, soybean.
• Vegetables and Root crops: bulb onion, carrots, forage beet, cucumber.
• Technical crops: common flax.

As a post-emergence foliar herbicide, «Oberig Grand» is best applied when weeds are actively growing to maximize the systemic effect. Formulated as an emulsifiable concentrate, the product is easy to prepare and mixes well with standard application protocols, though a compatibility test is always recommended prior to tank mixing.
