Pristar, WG, herbicide

Efficient Weed Control for Winter Wheat by Pest.Ua

In modern agricultural production, choosing a selective herbicide is a matter of both yield potential and cost-efficiency. The Ukrainian manufacturer Pest.Ua offers a solution for controlling broadleaf weeds in winter wheat fields—the «Pristar, WG» herbicide. This systemic herbicide serves as a localized response to the demand for accessible and high-quality crop protection products adapted to specific regional growing conditions.

Active Ingredient and Mechanism

The preparation is based on tribenuron-methyl, rightfully considered the "gold standard" for combating a wide range of weeds. As a systemic herbicide, Pristar penetrates through the leaves and quickly translocates to the growing points of the weeds, inhibiting the acetolactate synthase enzyme. This process effectively halts cell division, leading to the certain elimination of the target weeds.

Spectrum of Action and Application

The herbicide proves highly effective against some of the most aggressive competitors of grain crops:

• Common lambsquarters and wild mustard;
• Field pennycress and shepherd's purse;
• Common chickweed;
• Cleavers, purple dead-nettle, and field pansy.

The water-dispersible granule formulation ensures easy measuring and rapid dissolution in the spray tank. With a dosage rate of up to 25 grams per hectare, it serves as an economically viable tool for winter crop protection. As a post-emergence selective herbicide, Pristar allows growers to respond flexibly to the phytosanitary status of their fields, applying the treatment exactly when weeds are at their most vulnerable stage.

Practical Insights

Due to its high selectivity, the product is gentle on wheat, causing no growth depression. It is important to note that Pristar is designed for a single treatment per season. When handling the product, users should adhere to the 3rd hazard class safety protocols. Being a locally produced agricultural input, Pristar ensures full compliance with Ukrainian field regulations, minimizing the risks of unpredictable effects on crop development.
