Tava
Tava is a plant growth regulator, a soluble concentrate with ethephon 480 g/L, for wheat and barley against lodging: it restrains stem growth and makes the stem stiffer.
Main advantages
- Ethephon 480 g/L — forms ethylene in the plant
- Inhibits gibberellin synthesis — the stem grows less
- Wheat from BBCH 37, barley from BBCH 32 — until ear emergence
Overview
About this product
Tava is a growth regulator against lodging in wheat and barley with ethephon 480 g/L in a soluble concentrate. In the tissues ethephon breaks down to form ethylene, which inhibits auxin transport and gibberellin synthesis; the stem is restrained in growth and becomes stiffer.
Wheat is treated from the start of flag leaf emergence to the start of ear emergence (BBCH 37–48) at 0.75–1.0 l/ha, barley from stem elongation (BBCH 32–48) at 0.5–0.75 l/ha, once. Herbicides are not applied within 6 days before and after.
Pack size 5 l.
