WONKA combines natural active ingredients with fungicidal activity and elicitors of plant defense mechanisms. The datasheet lists horsetail decoction, willow bark extract and purified chitosan.
The technical description attributes bactericidal and fungicidal activity to chitosan and describes additional plant-defense and growth-stimulation effects associated with the formulation.
Key product information at a glance.
| Composition | % w/w |
|---|---|
| Decoction of horsetail (Equisetum arvense) | 2.0 |
| Willow bark extract (Salix spp. cortex) | 0.22 |
| Purified chitosan | 2.0 |
The datasheet links chitosan activity to its cationic character and describes effects on fungal cell-membrane permeability. It also describes stimulation of beneficial soil microorganisms, induced resistance, antiviral activity and growth stimulation.
Application Guidance: Use the crop-specific foliar dose, timing and interval shown in the datasheet. The documented range is 300-600 ml/hl depending on crop and objective.
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Apple trees and peach trees | From bud break to wilting of the flowers, in spring; 2-6 applications at 7-day intervals. | 300-500 ml/hl | Objectives include apple scab, powdery mildew and peach leaf curl. |
| Grapevine | From development of the first shoots until the berries start touching; 2-6 applications at 7-day intervals. | 300-500 ml/hl | Objectives: downy mildew and powdery mildew. |
| Cucumber | From the ninth unfolded leaf until nine or more visible lateral shoots; 2 applications at 3-4 day intervals. | 400-600 ml/hl | Objectives listed in the datasheet include Podosphaera xanthii and root fungi such as Pythium spp. |
| Tomato | From the first visible inflorescence until the flower is about to open, in summer; 2 applications at 14-day intervals. | 300-500 ml/hl | Objectives: early blight (Alternaria solani) and Septoria leaf spot. |
| Strawberry and raspberry | From restart of growth until the end of fruiting, from early spring to late summer; 4-8 applications at 5-14 day intervals. | 300-500 ml/hl | Objectives: gray mold, powdery mildew and Colletotrichum acutatum. |
| Potatoes | From bud break to fruit ripening; 4-8 applications at 5-14 day intervals. | 300-500 ml/hl | Objectives: late blight, early blight and powdery mildew. |
| Ornamentals | One foliar application when the first symptoms of disease appear. | 400-600 ml/hl | Objectives: Marsonia spp., Phragmidium mucronatum, powdery mildew and downy mildew. |
Documented targets include apple scab, powdery mildew, downy mildew, peach leaf curl, early blight, Septoria leaf spot, gray mold, late blight and other listed fungal diseases.
WONKA is described as compatible with most phytosanitary and nutritional products. Do not mix with alkaline products; if in doubt, carry out a prior compatibility test.
What is WONKA?
WONKA is presented as a broad-spectrum natural biofungicide and elicitor based on horsetail decoction, willow bark extract and purified chitosan.
How is WONKA applied?
The datasheet specifies foliar application with crop-specific rates from 300 to 600 ml/hl.
Can WONKA be mixed with other products?
The datasheet states that it is compatible with most phytosanitary and nutritional products but should not be mixed with alkaline products.
What does WONKA do besides direct fungicidal activity?
The datasheet also describes activation of plant defense mechanisms and growth-stimulation effects.
