Fungicide Tersel: instructions for use and composition, dosage and analogues

Apple diseases can reduce the yield and resistance of the trees themselves to external influences. Modern preparations are being developed for the treatment and prevention of fungal infections. Consider the possibilities of the fungicide "Tersel", specially obtained to combat these diseases. How the remedy works, how to make a solution, according to what norms to use according to the instructions. Compatibility of the drug and its substitutes.

Composition and release form of Tercel

The active ingredients of "Tersela" act in combination and reliably protect apple trees, both on the surface of the bark and leaves, and inside them.Works in dry and wet weather. The fungicide contains pyraclostrobin and dithianon at a concentration of 40 and 120 g per kg. Substances belong to the classes of strobilurins and quinones.

By the method of penetration, "Tersel" refers to contact pesticides, by the nature of the action - to protective pesticides. Manufacturer BASF produces the fungicide in the form of water-dispersible granules or suspension, in 5 kg bags or in 5 liter cans.

Mechanism and spectrum of action

Pyraclostrobin after spraying penetrates into the tissues of the apple tree and is distributed in the plant, even in those areas with which there was no direct contact of the drug. The substance blocks the cellular respiration of fungi. Dithianon remains on the surface in the droplet moisture and blocks the entry of pathogens inside. The substance stops the vital processes occurring in mushrooms, inhibits the activity of enzymes.

The active ingredients remain in stock in plant tissues, which makes them resistant to precipitation. At the same time, it is precisely because of moisture that they are gradually released and redistributed.

This happens in wet weather when fungus activity is highest. In addition, "Tersel" prevents the formation and germination of spores, which stops the penetration of infection. Can be used to protect harvested apples from rot during storage.

Fungicide consumption rate

From scab and powdery mildew, apple trees are sprayed prophylactically. Application time - from the stage of a rose bud to the stage of development of fruits the size of a walnut. The break between sprayings is 8-14 days, the interval depends on the level of infection and the weather. The maximum number of treatments is no more than 3 for the entire season.

Tersel consumption rate is 2-2.5 kg per ha.

Instructions for using the drug

The duration of the protective action of "Tersela" is 10-12 days. Scab and powdery mildew pathogens are not resistant to the drug.It is possible to apply the fungicide on plants in any phase of development, even during flowering. Its action does not depend on temperature conditions. The waiting period after the last spraying is 35 days. Before the waiting time is over, you cannot collect and use fruits from processed apple trees.

Safety precautions

When diluted in normalized dosages, Tercel is non-phytotoxic. It is low toxic to humans, bees, toxic to fish and aquatic organisms (gardens located close to water bodies should not be sprayed). May be harmful if swallowed, may irritate eyes.

If it is not indicated in the instructions whether the pesticides are compatible or not, it is necessary to dilute the preparations in a small volume before preparing the solution. If there are no unexpected reactions, they can be shared.

Storage conditions and expiration date
