prevention measures
field anthracnose activity is not limited only cucumbers, under his influence fall vegetable crops such as melons, pumpkins, watermelons.Anthracnose (or copperhead cucumbers) can reduce the yield by half, destroying virtually all plants;Infection can persist in the soil on plant debris and infected seeds.Therefore, to prevent anthracnose should follow some rules:
- promptly remove and dispose of the remains of vegetation from the site after the harvest;
- comply with crop rotation, ie to plant cucumbers in a previous landing no earlier than 3 years;
- seed collection made exclusively from healthy plants;
- select varieties of cucumbers are resistant to diseases;
- etched preparations seeds before sowing;
- disinfected soil, construction of greenhouses and tools;
- restore the health of the soil by adding organic fertilizers and biological products.
Optimal conditions for the spread of anthracnose Anthracnose
cucumbers - a disease that gets most its activity at high humidity;dew and rain and above-zero temperatures from 4 to 30 degrees - the most komfornosti conditions for its spread.The incubation period lasts 4 to 7 days.At a temperature of + 20-25 degrees ripening period of the fungus is reduced and is three days.When humidity less than 60% of cucumber anthracnose does not occur.In addition multiplication conidia when sprinkling with condensation and irrigation water, the fungus is transmitted through contact with sick healthy plants, with cross-ventilation, is transferred to the working clothes, aphids and spider mites.
fungus overwinters, not only on the left after harvesting the plants, but also on film and glass greenhouses and their constructions.The collected seeds can be so dangerous to native plant infection.
fight against anthracnose
addition to the above preventive measures aimed at preventing the disease cucumber anthracnose, which is required to carry out the treatment with a competent approach can be overcome with the help of chemicals.Seeds before planting is recommended to etch the fungicide TMTD per 1 kg - 4 grams of the drug.This operation can be performed 2-3 weeks before planting.Action treater applies to the entire growing period and is slowing down and stopping the process of cell division and nuclear pathogenic fungi, which are located in the plant and soil.Before sowing, seeds are also recommended to soak in a solution of bio-stimulator "Immunotsitofit."Its action carries a preventive sense, forms the high resistance of plants to various diseases (including fungal), stimulates the rapid growth of culture and passing it different biological processes.
Upon detection symptoms required to spray crops 1% suspension of colloidal sulfur and treat 0.5-1% strength Bordeaux mixture, copper oxychloride or "Poliramom";such a measure at the same time will be the prevention against the appearance of mildew.To the affected area it is recommended to apply a 0.5% solution of copper sulfate, and then dusted with powdered charcoal, honey or lime.From modern recommended use of the drug "Zineb" at the rate of 20-30 grams per 10 liters of water or "ziram" - in the same amount of water is 30-40 grams.
Basal irrigation as a measure to combat copperhead
At the root form of anthracnose high effect gives dips 1% solution of liquid Bordeaux or a 0.5% solution "Abig Peak" at the root of each plant.You first need to moisten the soil liberally with water and then pour under every bush solution of the drug in a way that most of it came under the root, and the rest - on the stalk (at the rate of 0.5-1 liters per vegetable crops).Such treatment may be repeated, if necessary, 2-3 times a week.Be sure you want to protect the solution from falling leaves.
No antrankozu!
Anthracnose Cucumber, treatment which is not only in the processing of chemicals, but also in the application of preventive preventive measures will be successfully overcome during the above-described events at the complex.
