Synergy against pests: the potential of «Stefotruta»

In the crop protection market, products combining the power of organophosphates and pyrethroids occupy the niche of "heavy artillery". «Stefotruta», manufactured by DDE Farm AG (Triesen, Liechtenstein) on behalf of Stefes, is a classic representative of this group. The effectiveness of the product is based on the combination of chlorpyrifos and cypermethrin — a combination that has remained a benchmark in the fight against resistant insect populations for decades.

Technical profile and mode of action

The product is an emulsifiable concentrate, which ensures excellent adhesion to the leaf surface and rapid penetration into the pest's cuticle. Its contact action allows «Stefotruta» to effectively strike insects both through direct hit of the solution and via contact with the treated plant surface.

• Active ingredients: Chlorpyrifos and Cypermethrin.
• Type of action: Contact insecto-acaricide.
• Control spectrum: Weevils, ground beetles, cereal leaf beetles, aphids, sunn pest and flea beetles.

Field application

The main crops for the application of this plant protection product are winter wheat and fodder beet. The use of «Stefotruta» is justified during periods of high pest activity, when it is necessary not only to stop the feeding process, but to rapidly reduce the population density. The application rate varies from 0.5 to 1.5 liters per hectare, depending on the phytosanitary situation. According to the regulations, a maximum of two treatments per season is allowed, with an interval ensuring a pre-harvest interval of at least 30 days. Given its Class 2 hazard rating, handling the product requires strict adherence to safety measures and consideration of weather conditions to prevent spray drift.

For agronomists, «Stefotruta» from DDE Farm AG is a tool that requires no long adaptation to new protection protocols, relying instead on time-tested chemical protection classics.
