Gaucho 70 WS

An Engineering Approach to Seedling Protection

The core of Gaucho 70 WS is imidacloprid at a concentration of 700 g/kg. This is not just an insecticide, but a high-tech solution for pre-sowing preparation, where the formulation—a wettable powder—plays a decisive role. This specific physical and chemical form ensures an even distribution of the active ingredient over the seed surface, creating a protective barrier without the risk of over-application or dusting off during seed transport.

Systemic Dynamics and Contact Efficiency

The technical advantage of Gaucho 70 WS lies in its dual-action mechanism: contact and systemic. Once the seed enters the soil, imidacloprid exhibits contact activity, neutralizing attempts by soil pests, such as wireworms or ground beetles, to damage the seed coat. Subsequently, the systemic mechanism takes over: after germination, the substance is absorbed by the root system and transported acropetally up the plant's vascular system. This establishes a long-lasting protective barrier for the above-ground part of the crop, preventing attacks by sucking pests (aphids, leafhoppers, cereal flies) during the most vulnerable stage—seedling emergence.

Practical Implementation and Benefits

The choice of this Bayer product is driven by its selectivity and high bioavailability across various crops: sunflowers, maize, sugar beets, winter and spring cereals, and potatoes. Using this seed treatment allows growers to shift focus from early-stage pest control to optimizing crop nutrition and development. Given its WHO Class III toxicity rating, when used in accordance with the regulations, the product offers an ideal balance between efficacy against pathogens and operational safety. The stability of the formulation ensures predictable performance even under fluctuating soil moisture conditions, which is critical for protecting winter crops in unstable autumn climates.
