"Ordan" - effective protection and treatment of vegetables from diseases
Vegetables during the growing season can be subject to various diseases. The disease that appeared, it would seem, from nowhere is capable of killing plants in a matter of days and leaving the gardener without a crop. And mushroom diseases can appear for various reasons - infected planting stock, weakened seedlings, bad weather conditions.
Dangerous diseases of tomatoes, cucumbers and potatoes
Late blight is the most dangerous fungal disease that affects, most often, tomatoes, potatoes, eggplant and pepper. Manifestations of the disease usually occur in the second half of summer, when nights become cold and a significant difference in daily temperatures appears. High humidity, dew in the morning or lingering cool rains contribute to the rapid progression of the disease.
Brown spots appear on the leaves of vegetable crops, and on the lower side of the leaf plate you can find a white coating - these are spores of the fungus. Affected leaves quickly die and fall off. With watering and rains, spores penetrate the soil, which contributes to the spread of the disease. Gray spots appear on the potato tubers, which eventually turn into rot.
Blight spreads very quickly and, if it is not noticed and taken in time, can cover all plantings within a week. The main thing here is not to miss the time, because if more than 10% of all leaves of the plant are affected, it will be impossible to defeat late blight. Therefore, it is very important to carry out preventive measures at the beginning of the growing season.
Alternariosis is another common fungal disease that affects a wide variety of cultures. Most often, the fungus appears on the leaves of plants, sometimes it passes to the stems and tubers. The first manifestations of the disease can be noticed during budding - round brown necrotic spots appear on the leaves. Spores of the fungus with gusts of wind are transferred to healthy plants, leaving less and less chance of saving the crop.
Cucumbers, zucchini and other representatives of pumpkin are often affected by peronosporosis, or downy mildew. The causes of the disease are several:
- cultivar unstable to peronosporosis;
- prolonged high humidity;
- excess nitrogen in the soil with a lack of potassium;
- infected planting material;
- plant residues;
- a large difference in daily temperatures.
The appearance of peronosporosis can be recognized by rusty oily spots on the surface of the leaves. On the underside of the leaf, spores of the fungus in the form of grayish spots can be detected. Spreading, spots cover the entire plate of the sheet, which dries and dies. Peronosporosis develops very quickly and under favorable (for him) weather conditions in three days it can destroy all plants.
"Ordan" - an effective fungicide for prevention and treatment
As you know, any disease is easier to prevent than to treat, and especially this applies to fungal diseases. So, for example, the strict implementation of all techniques of agricultural technology when growing vegetables will help significantly reduce the risk of peronosporosis, but its appearance can be completely eliminated only with the help of preventive treatments.
For the prevention and treatment of tomatoes, cucumbers and potatoes, the company "August" offers an effective tool "Ordan." This unique drug combines immediately 2 active substances with various mechanisms of action. One, penetrating the plant tissue, stops and destroys the disease if infection has already occurred, the second - remains on the surface of the leaves, creating an insurmountable barrier to infection.
The broad-spectrum fungicide "Ordan" compares favorably with other similar products in several ways:
- effective both as a preventive and as a therapeutic agent;
- not addictive in infectious agents;
- short waiting period - you can harvest a crop already 3-5 days after processing;
- low toxicity for humans and pets.
Features of the use of the Ordan fungicide
The drug is conveniently packaged in 12.5 g (water-soluble bag) and 25 g (regular bag). For the prevention and treatment of late blight and peronosporosis, plants are sprayed three times in the phase of 4-6 true leaves or during the first two days of infection.
Preventive spraying of potatoes is carried out before the leaves close in rows. Subsequent treatments are carried out at intervals of 7-10 days. The solution is prepared at the rate of 25 g per 5 liters of water. This volume is enough to process 100 m2. For greenhouses, a more concentrated solution is prepared - 25 g per 8 liters of water.
All details on working with the drug - breeding rates, methods of application on different cultures and safety measures are described in detail in the attached instructions for the drug.
