Colloidal sulfur (another common name - fungicide) is used everywhere to protect all horticultural crops from most pests and diseases, including powdery mildew, ascochitosis, keel, plant mites, oidium, anthracnose, and scab.
The fight against any of these diseases begins already at the first sign of its manifestation. Processing is carried out with an absolute absence of precipitation and wind. It is very important to moisten the leaves on both sides, evenly. Sulfur colloidal phytotoxic effects usually do not cause (if you follow the instructions and follow the dosage), but sometimes it is still possible undesirable damage (for example, in some varieties of gooseberries), up to the falling of flowers and part of the leaves. Therefore, it is better not to process the plants during flowering.
Colloidal sulfur should not be mixed with other drugs, although the combination with some fungicides is allowed by the instruction. However, chemicals are prone 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 process cabbage against keel or sugar beet against powdery mildew, a sachet of the drug is diluted in ten liters of water. A liter of solution is designed for 10 m². Triple processing.
2. For the treatment of powdery mildew cucumbers:
- in the open ground 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-fold processing);
- for protected soil, the working solution is prepared from 10 liters and 40 g of the drug (two liters of solution are designed for 10 m², five-time treatment).
3. For the treatment of melons and watermelons from ascochitosis, anthracnose, powdery mildew in 10 liters of water, one sachet is bred (40 g). 10 m² is treated with a liter of solution. Sprayed thrice.
