Fungicide Collis: instructions for use, mechanism of action, consumption rate

When looking for a good effective drug for getting rid of oidium caused by powdery mildew fungi, it is recommended to opt for the Collis fungicide. The drug is able to provide good protection of grapes from fungal infections from spring to late autumn, without affecting the quality of the original product.

Composition, purpose and release form of the Collis fungicide

The main components of the fungicidal preparation:

• 200 g/l boscalida;
• 100 g/l kresoxim-methyl.

Boscalid belongs to the chemical group of carboxamides and has a mechanism of action that extends to a certain spectrum of the pathogen. Kresoxim-methyl inhibits mitochondrial respiration by inhibiting cytochrome c reductase activity.

The drug is produced in the form of a suspension concentrate in plastic canisters from 1 to 10 liters. It is prescribed for the treatment of oidium at any stage in different grape varieties.

How does the drug work?

During processing, some components of the fungicide remain on the surface of the plant, providing reliable protection against resistance and damage by other pathogens, while other substances pass into the body and spread through the conducting system in search of the pathogen. The essence of the action of the fungicide is to inhibit the mitochondrial cycle. Subsequently, difficulties with breathing appear, the formation and germination of spores stops, and further development of the infection is excluded.
