Colloidal sulfur (another common name is fungicide) is used worldwide to protect all horticultural and horticultural crops from most pests and diseases, including powdery mildew, ascochitosis, clubroot, plant mites, oidium, anthracnose, scab.
The fight against any of these diseases begins at the first sign of its manifestation. Processing is carried out in the absolute absence of precipitation and wind. It is very important to wet the leaves on both sides, evenly. Colloidal sulfur usually does not cause phytotoxic effects (if you follow the instructions and follow the dosage), however, sometimes unwanted damage is still possible (for example, in certain varieties of gooseberries), up to the fall of flowers and part of the leaves. Therefore, it is better not to process the plants when flowering.
Colloidal sulfur should not be mixed with other drugs, although the instructions allow combining with some fungicides. However, chemical reagents tend to give reactions, so in order not to be left without a crop, it is better to abandon the experiments. Standard packaging - 40 g.
Colloidal sulfur application
1. To treat cabbage against clubroot or sugar beet against dew, a powdery sachet of the drug is diluted in ten liters of water. A liter of solution is designed for 10 m². Processing three times.
2. To treat powdery mildew on cucumbers:
- in the open field, a working solution is prepared from 20 liters of water and 40 g of the drug (a liter of solution is designed for 10 m², four times treatment);
- for protected soil, the working solution is prepared from 10 liters and 40 g of the preparation (two liters of solution are calculated for 10 m², five times processing).
3. For the treatment of melons and watermelons from ascochitosis, anthracnose, powdery mildew, one sachet (40 g) is diluted in 10 liters of water. 10 m² is treated with a liter of solution. Sprayed three times.
4. To protect currants from powdery mildew, a sachet of the drug is diluted in 10 liters of water. One bush will require 1.5 liters of solution. Processed three times.
5. For the treatment of apple trees, quince, pears against scab and dew, the powdery package of the drug is diluted in 5 liters of water. A young tree consumes about two liters of solution. For an adult, the volume of the solution is increased depending on the size of the tree. Processing five times.
6. Treatment of grapes against oidium is carried out with a solution of 5 liters and a sachet of the drug. Approximately 1.5 liters of solution is consumed per 10 m². On average, six treatments are required.
7. Powdery mildew medicinal crops are treated with a solution prepared from 4 liters of water andsachet of colloidal sulfur. The consumption rate is a liter per 10 m². Double processing.
8. Flowers, flowering crops against anthracnose, ascochitosis, powdery mildew require treatment with a solution of 5 liters of water and a sachet of the drug. Approximate consumption per 10 m² - a liter of solution. Spraying five times.
9. The remaining cultures against plant mites are treated with a solution of colloidal sulfur prepared from 5 liters of water and a sachet of the drug. Spraying five times.
Intervals between treatments are 10-15 days. The last spraying can be carried out 3 days before harvest. The solution is prepared by gradually adding water to the preparation and consumed on the same day. In a diluted form, colloidal sulfur is not stored. Action starts 3 hours later.
