Overview
About this product
Sumaro is a selective systemic herbicide for maize with mesotrione 480 g/L in a suspension concentrate. Mesotrione, from the triketone group, enters weeds through the leaves, roots and shoots and inhibits the enzyme HPPD, without which carotenoids are not formed; light then destroys the chlorophyll and the leaves lose their colour.
Growth of susceptible weeds stops within 1–2 days. Maize is treated once at the 3–8 leaf stage at 0.25 l/ha together with 0.25 l/ha of surfactant.
Among the targets the manufacturer names volunteer sunflower and oilseed rape, including volunteers resistant to imidazolinones and tribenuron-methyl. Pack size 5 l.
