Systemic fungicide for the control of powdery mildew and gummy stem blight in pumpkin and winter squash.


General Instructions

General Information

COLLISS is a novel combination of carboxamide and strobilurin type fungicides providing protectant activity against powdery mildew and gummy stem blight. It is locally systemic and translaminar to provide some protection to new growth. Thorough coverage of the crop is necessary for best results. Best results are obtained from protectant applications prior to the onset of infection.

Resistance Management

COLLISS contains boscalid, a carboxamide fungicide from the SDHI (Succinate Dehydrogenase inhibitors) mode of action group GROUP 7 FUNGICIDE, and kresoxim-methyl, a stobilurin type fungicide from the QoI (Quinone outside Inhibitors) mode of action group GROUP 11 FUNGICIDE. Resistance to this fungicide could develop from excessive use. To minimise this risk use strictly in accordance with the label instructions and resistance management strategies that exist for any fungus listed on the label. COLLISS should be used in a programme that incorporates fungicides with different modes of action to GROUP 7 and GROUP 11 fungicides, and that have satisfactory efficacy against the targeted pathogen(s) e.g. sulphur or triazoles. Refer to the NZCPR web site ( for more detailed information. It is an offence to use this product on animals.
