TEBUCO 87 WG – DVA is a preventive and curative systemic fungicide that inhibits sterol biosynthesis. It works by preventing the pathogen from completing its infection process and it also reduces the production of conidia in established lesions. The active substance is quickly absorbed by the parts of the plant that take part in the assimilation process and is transported acropetally (upwards). This systemic movement ensures its distribution within the plant and, in addition, allows the active substance to have less risk of being washed by rainwater or irrigation.
