For Phytophthora – copper has dissolved
Late Blight – a very dangerous disease of potatoes. It affects the leaves of plants, bulbs, dramatically reduces the quality of products. Active protection should be at the beginning of the disease, which usually coincides with the phases of budding-flowering plants.
To increase the stability of phytophthora in potato bushes reaching heights of 15-20 cm they need to process with copper sulphate at 10 g per 10 liters of water. Ten days later, spray again.
The first preventive spraying potatoes spend between budding and early flowering one of the so-called contact fungicides: 1% Bordeaux-term liquid (100 g copper sulphate + 100 g svezhegashenoy of lime per 10 liters of water), 0.4% solution of copper oxychloride (40 g per 10 liters of water), 0.5% solution oksihoma (for instructions), 0,4% solution polihoma (40 g per 10 liters of water).
Second processing carried out when the first infected leaves, the next – with an interval of seven to ten days. Results should be done not less than 3.4 sprays.
In the fight against late blight of potato also use and highly effective systemic fungicide ridomil MTs. It is usually used in the second treatment in a 0.5% concentration (50 g per 10 liters of water). Waiting period (from the date of last treatment to harvest) – 20 days.
Keep in mind that fungi Phytophthora quickly become accustomed to ridomilu MTs. Therefore, you should either alternate this drug with other contact fungicides, or used in a mixture with one of them.
Do not get carried away by nitrogen
Tomatoes are significantly affected by fungal, bacterial and viral diseases, which drastically reduces the quality and quantity of the harvest. The most important condition for obtaining excellent products are preventive measures aimed at improving disease resistance of plants.
Foliar feeding vegetable plants micronutrients to improve their resistance to disease is expedient to combine with fertilizers in the soil. In the presence of trace elements (copper, zinc, manganese, iron, and so on) plants make better use of basic fertilizers (nitrogen, phosphorus, potassium).
Significant distribution and harmfulness are viral diseases.
Improves the resistance of tomatoes range of infections and increase their yield of two-three times spraying with copper sulphate (20 g per 10 liters of water). Responsive tomatoes on a three-time watering 0,05% solution of manganese sulfate (5 g per 10 liters of water), as well as two-three times spraying with 0.2% solution of zinc sulphate (20 g per 10 liters of water).
Significantly increases the stability of tomatoes to viral diseases, phytophthora in two-three times the foliar feeding of superphosphate and ammonium nitrate (10-15 g per 10 liters of water), potassium salt (5-10 g per 10 liters of water).
Foliar feeding makroudobreniyami can be combined with the use of micronutrient fertilizers. But remember that excessive application of nitrogen fertilizers for tomatoes reduces their resistance to disease and reduces the keeping quality during storage.
One of the most affordable and effective means of protection against viral diseases of tomato is a two-three times spraying with 10% reversible (1 liter to 10 liters of water).
When the first signs of Phytophthora can be applied copper-soap emulsion (20 g copper sulphate + 200 g of soap in 10 liters of water). Of special agents against fungal diseases listed above can be applied 0,5-1%-ing Bordeaux liquid, 0,4% solution of copper oxychloride (40 g per 10 liters of water). Processes tomatoes with an interval of 10-14 days.
