Sembria

Spirotembria

The only insecticide here that travels down to the roots as well as up.

Spirotetramat 100 g/l
Spirotembria — SC - Suspension Concentrate — Sembria

Spirotembria is based on spirotetramat, and its distinguishing feature is two-way systemic movement: it travels both up in the xylem and down in the phloem. A foliar spray therefore reaches sucking pests on parts of the plant the spray never touched — including root mealybug and scale under bark. Against psyllids, aphids, mealybug and scale, that reach is worth more than knockdown speed.

Characteristics

  • True two-way systemic movement — reaches roots and hidden tissue from a foliar spray
  • Excellent on psyllids, aphids, mealybug and scale insects
  • Controls pests sheltering under bark and below ground
  • IRAC Group 23 — a lipid biosynthesis inhibitor
  • Comparatively soft on many beneficial insects
  • Effective on immature stages and reduces female fecundity

How it works

Spirotetramat inhibits acetyl-CoA carboxylase and blocks lipid biosynthesis. Immature insects cannot develop and adult females produce far fewer viable offspring. Its phloem mobility is what sets it apart — most systemics move only upward. Effect builds over days rather than hours. IRAC Group 23.
