What you need to know about the drug
The Topsin fungicide is produced in the form of an emulsion or powder. The dry matter dosage is more common in large packages weighing 1-10 kg. Such packaging of Topsin is convenient for farmers, as well as owners of large plots of land. For private use, there is a small dosage of the fungicide of 10–25 g. However, the emulsion is more popular. For Topsin M 500 SC, the instructions for use are the same as for the powdery substance. The advantage of the emulsion is the readiness of the fungicide for use, as well as a convenient dosage for a private trader. The drug is sold in vials with a capacity of 10 ml.
The main active ingredient of the drug is a pesticide called theophanate-methyl. Fungicide belongs to the class of drugs of average toxicity, does not cause chemical burns of the skin and mucous membranes. For Topsin M, the instructions for use provide for the treatment of plantings by spraying. The active ingredient of the fungicide is rapidly absorbed by the whole tree or plant. The pesticide destroys fungal spores, prevents the awakening of the mycelium, heals the affected areas. Additionally, the fungicide protects the green mass from aphids and other leaf beetles.

- the protective period of the fungicide lasts up to 1 month;
- the fungicide is compatible with all preparations that do not contain alkali and copper;

The action of the active substance
The systemic action of the Topsin fungicide is at the same time the prevention, treatment and destruction of the developing fungus.
Often the disease occurs in stone fruit varieties. The fungus in the spring affects the buds, foliage, appearing on the plates with brown specks. After 10-14 days, the plots dry up and crumble. The foliage becomes all in small holes.
Over time, the fungus spreads to the fruit. Symptoms are similar. First, spots appear, turning into dry rot.The fruits fall off along with the foliage, keeping the spores of the fungus all winter until next spring. With the onset of heat, the causative agent of the disease awakens. Fungal spores are activated at a temperature of +4aboutC. There is an infection of neighboring plantations with the help of wind and insects.
The main method of control is burning in the fall, affected by fallen leaves and fruits. Dry and recovered shoots are cut from trees. In the spring, immediately after flowering, the first treatment with Topsin is carried out. The procedure is repeated two weeks later.

Application instructions
If it is decided to use Topsin M fungicide, instructions for use are written on the original packaging and must be followed. Regardless of the use of powder or emulsion, the solution is prepared on the day of use. According to the instructions, the required dose of Topsin is dissolved in water. The finished fungicide solution is thoroughly mixed, filtered, and then poured into the sprayer tank.
Usually, for Topsin M, the instructions for use say that 10 to 15 g of the drug are dissolved in 10 liters of water. Spraying is recommended during the growing season. Do not use fungicide during flowering. The best period is before bud or after harvest. There should be no flowers on a tree or garden crop. During the season, 2 treatments are carried out, otherwise the drug will not bring benefits.
Spraying with fungicide is carried out in clear, calm weather. The repeated action is performed no earlier than 2 weeks later. It should be noted that Topsin is addictive. From frequent use, fungi adapt to the drug and acquire immunity. For the best effect, adhere to the annual alternation using analogs. Tsikosin, Peltis have proven themselves well, but in such matters, an individual recommendation of a specialist is needed.
Compliance with safety measures when treating plantations with fungicides
Topsin's instructions for use state that when working with the drug, it is imperative to observe precautions. In terms of danger to humans, the fungicide belongs to the second class. Topsin will not bring any particular harm to the skin and mucous membrane, but you cannot spray without a respirator and rubber gloves. It is advisable to wear glasses when processing trees. From a height, sprayed mist will settle and may enter the eyes.
A feature of Topsin is an effective action aimed at increasing yields by almost two times. Farmers use this. When processing your plantations, you need to take into account that there will be no particular harm to bees and birds. However, it is difficult for fish to tolerate the ingress of the fungicide into the water. Topsin should not be used near bodies of water. It is strictly forbidden to pour out the remains of the solution, and to wash the equipment in water.
Application of the drug for different types of crops
Before starting use, read the instructions for use on the Topsin fungicide packaging, where the recommended dosage is indicated. It will be different for different garden crops and trees. If spraying is needed for treatment, the degree of infection is additionally taken into account.
Dry Topsin powder is dissolved until the crystals disappear completely. The fungicide emulsion can be dissolved in a small amount of water directly inside the spray tank. Close the container tightly with a lid, shake it several times, open it and add water to the required rate. The closed tank is shaken again, pumped up with a pump and proceed to spraying... During the procedure, periodically shake the balloon to avoid sediment formation.
Spraying cucumbers
The fungicide effectively protects cucumbers from powdery mildew. The planting is cultivated twice a season.With an open cultivation method, spraying is allowed to be carried out with the emergence of shoots and before the formation of an ovary. Flowering time is excluded. It is best to spray early. The drug is valid for 1 month, and at the time of harvest, this period should preferably be over. 1 m2 beds usually need 30 ml of solution. The concentration of the active substance reaches approximately 0.12 g / 1 liter.
Roots
Most often, the fungicide is in demand for beets, but it is also suitable for other root crops. The drug protects against powdery mildew, as well as manifestations of cercosporosis. During the season, 3 treatments are carried out every 40 days. It is this time that Topsin effectively protects root crops. Consumption of ready-made solution per 1 m2 is about 30 ml. The concentration of the active substance is adjusted to 0.08 g / 1 l.
Fruit trees
All fruit-bearing trees are sprayed twice a season. The best period is considered to be early spring before the onset of buds and the end of flowering, when a young ovary appears. The protective effect lasts for a maximum of 1 month. The consumption of the finished solution depends on the size of the tree and can reach from 2 to 10 liters. The optimal concentration of the active substance is 1.5%. The action of the drug extends to the destruction of pathogens of scab and powdery mildew.
Vineyards and berry bushes
Spraying of berry bushes and vines is carried out before the onset of flower stalks, as well as after harvesting. While pouring berries, processing is prohibited. Rapid ripening does not make it possible to completely neutralize all substances that are undesirable for ingestion.
The protective actions extend to the resistance to gray rot, as well as the occurrence of anthracnose. Vineyard fungicide protects against powdery mildew. The consumption of the finished solution depends on the size of the bush and can reach 5 liters. The optimal concentration of the active substance is 1.5%.
