About Curzate® M WG


Curzate® M WG will control strains of blight both resistant and sensitive to phenylamides (e.g. Metalaxyl). The rapid penetration of cymoxanil into the leaf and its post-infection, curative activity means that Curzate® M WG provides blight protection both inside and outside the leaf and is effective even under irrigated conditions.

Curzate® M WG combines the security of the full rate of macozeb, the leading protectant, with the semi-systemic activity of cymoxanil, which provides an additional timing flexibility of 2-3 days compared with purely protectant mixtures.

Curzate® M WG is not damaging to the foliage of potatoes, which together with its excellent blight activity ensures consistent improvements in yield and tuber quality. It can be applied right up to the end of a blight programme, with sprays continuing as long as blight conditions last.
