Active ingredients: Propamocarb – 530 g/l, aluminium fosetyl – 310 g/l.
Preparative form: water-soluble concentrate.
Mechanism of action:
Propamocarba - is based on interrupting the formation of fungal cell membranes and suppressing mycelial growth, blocking the formation and germination of spores.
Fosetyl - based on a combination of two principles:
1. Direct effect on pathogenic micromycetes - fosetyl stops the disease by inhibiting the germination of spores and the penetration of the pathogen into the plant (preventive effect); blocks mycelium development and sporulation (therapeutic effect).
2. The indirect effect is based on the fact that fosetyl enhances the protective and immune response of the plant, which significantly reduces the ability of pathogens to penetrate and develop in plant tissues. The activation of such mechanisms is called “System Acquired Resilience” (SAR).
Purpose: the drug is highly effective against pathogens that cause root and basal rot (Pythium spp., Rhizoctonia spp., Fusarium spp.), as well as against late blight (Phytophthora), downy mildew (Peronospora) on vegetables (tomato, cucumber, pepper, lettuce) protected soil.
In addition, Previcur® Energy suppresses the development of fusarium in substrates and, in some cases, bacteria of the genus Pseudomonas.
Action: the effect lasts up to 2-3 weeks, depending on the degree of infection of the plants. Speed of influence – within 2-4 hours from the moment of treatment. In conditions of severe disease damage and rapid plant development, the intervals between treatments should not exceed 7-14 days.
Instructions for use: treatment is carried out in the morning or evening, in dry, windless weather.
Compatibility: Previcur is compatible with many pesticides, with the exception of highly alkaline substances. However, in each specific case, before use, it is recommended to check the drug for compatibility.
Directions for use: Previcur working solutions are prepared in food-grade plastic or stainless steel containers since the active ingredients of the drug actively react with metals and filler components of non-food plastics. The working solution should be used during the day.
Safety precautions: when working with the product, it is advisable to use protective clothing, a respirator, goggles and gloves. Avoid contact with skin and eyes. Also, do not inhale vapours when preparing the working solution and spraying.
Application: systemic fungicide for combating diseases of cucumbers, zucchini, eggplants, melons, watermelons and other cucurbits, tomatoes, peppers, lettuce, radishes, white cabbage, leaf and cauliflower, salad and ornamental plants in greenhouses and outdoors.
The drug Previcur Energy contains two active ingredients that complement each other both in the spectrum of action and in the effectiveness of control.
Propamocarb stops the formation of the fungal cell membrane; inhibits the growth of fungal mycelium, as well as the formation and germination of fungal spores.
Fosetil increases the systemic resistance of plants to fungal diseases by stimulating the natural defense system of plants. At the same time, fosetil has a preventive effect on infection - it does not allow spores to germinate and penetrate the plant. Fosetil also has medicinal properties — the active substance suppresses the release of spores from sporangia and stops the development of mycelium.
Maximum number of uses:
Plants growing on mineral wool can be watered 4 times; plants growing in soil 2 times;
Plants can be sprayed up to 2 times during the growing season.
Extended use: to combat fungal diseases on trunks and shoots in plantings of Norway spruce, birch and Scots pine.
Consumption rate:
6.0 l/ha; 600 ml/1000 m2; 60 ml/100 m2 - 3 sprays. At a consumption rate of 3 ml/m2, if the consumption of the working solution is 20,000 l/ha, prepare a 0.15% solution: mix 150 ml of Previkur Energy with 100 l of water (or mix 15 ml of Previkur Energy with 10 l of water, the consumption of the working solution is 2 l/m2).
Spray coniferous crops 2-4 weeks after sowing, birch crops after emergence with an interval of 30 days.
Preparation of the working solution: shake the bottle with "Previсur Energy" thoroughly before opening it. Add the preparation, mix thoroughly, and then add the remaining amount of water. Use the prepared spray solution immediately. Prepare only the required amount of spray solution. Rinse the used container 3 times with clean water and add the rinse water to the prepared spray solution.
Cleaning the sprayer: after finishing work, thoroughly wash the sprayer, hoses and nozzles with water and a special detergent. For this purpose, you can use regular baking soda, adding 200-400 g per 10 l of water.
