For potato growers, Curzate™ fungicide is the heart of an effective preventative late blight program. It’s highly effective because of its preventative, post-infection and antisporulant activity. Curzate delivers unique kick-back action and deals with disease at the point of infection.
Curzate fungicide is a powerful, locally-systemic fungicide registered for the control of late blight when tank-mixed with Manzate® Pro-Stick™. Curzate is the only systemic fungicide to feature post-infection protection from late blight in the field. Post-infection activity is an integral part to a multi-level approach in controlling late blight.
Curzate inhibits sporangium and zoospore germination. This activity is synergized in combination with Manzate® Pro-Stick™ protectant fungicide.
When Curzate is applied 1 to 3 days after infection and before symptoms appear(1), it can stop initial stem and foliar lesion development. Curzate provides up to 72 Hours of post-infection disease control. (1) Curzate will not control late blight when it has advanced to the infectious stage and lesions are visible.
Curzate suppresses sporulation, reducing total spore counts and reducing spore viability on already developed stem lesions. Oospore development is also inhibited where conditions are present for sexual reproduction.
Curzate is the only Group 27 fungicide so it controls the disease at a unique site of action. Curzate should be used as part of a proactive disease management program to ensure multiple modes-of-action are used in controlling late blight.
