Description
ACTION OF OBSERVER PRO:
OBSERVER PRO features a dual-action mechanism against pathogens, which drastically reduces the risk of resistance development in fungi. The product exhibits strong systemic and surface activity. Propamocarb hydrochloride penetrates deeply into plant tissues, quickly moving within, ensuring full protection of newly emerging leaves and stems, even under conditions of intensive biomass growth.
Meanwhile, zoxamide binds excellently to the waxy layer on the plant surface, creating a durable protective barrier highly resistant to wash-off by rain. This synergy blocks spore germination and inhibits the development of potato late blight mycelium at every stage of its life cycle. The product performs excellently under varied weather conditions, offering long-lasting preventive and curative effects.
CONTENT OF ACTIVE SUBSTANCES:
propamocarb hydrochloride (a compound from the carbamic acid derivatives group) – 450 g/l (41.22%)
zoxamide (a compound from the benzamide group) – 67.5 g/l (6.18%)
Advantages of using OBSERVER PRO:
- Comprehensive protection of young growth: Systemic action ensures the product also protects parts of the plant that have grown after spraying.
- Exceptional wash-off resistance: Strong binding to the leaf wax layer guarantees stable plantation protection even during rainy weather.
- Anti-resistance strategy: The combination of two different chemical groups effectively blocks the development of resistant strains of potato late blight.
- Wide application window: Usable from early stages of lateral shoot development until the end of fruit development phase.
Pre-harvest interval:
- Potato - 7 days
OBSERVER PRO - SCOPE OF USE, TIMING AND DOSES:
Potato
| Target pests: | Potato late blight |
| Maximum / recommended dose: | 2.0 l/ha |
| Application timing: | Apply the product from the beginning of lateral shoot development on the main stem, when the first lateral shoot is visible (>5 cm) until the end of fruit (berry) development phase (BBCH 21-79). Perform the first treatment according to forecasting or: − on early variety plantations: at the onset of first disease symptoms, − on late variety plantations: at the onset of first disease symptoms on early varieties. |
| Maximum number of treatments: | 3 (interval between treatments: at least 7 days) |
| Recommended water volume: | 150 - 300 l/ha (adjust spray liquid volume to plantation density; fine droplet spraying recommended) |
