Astra copper oxychloride 1 kg

Homemade use: 20-40 g/10 l water

The preparation is recommended for use in apple crops as a spring and autumn foliar spray against bacterial and fungal diseases (scab, monilia, twig dieback, etc.).
Controls against fire blight should be carried out as a preventive measure, from bud break until the end of green bud stage, at 2-3 intervals of 7-10 days, with high application rates. After waxing of the crop, the product can be re-applied for final spraying, taking into account the copper sensitivity or risk of scorch.

In nursery stock, seedling and nursery stock nurseries, for control of needle dieback, apply 2-3 times every 14 days in the period prior to infection with 300-400 l/ha of water.

In berry crops, it is recommended to apply as a wash spray at the beginning of the growing season and after harvesting for control of cane and leaf spot diseases.

In potatoes, treatments should be started preventively based on a forecast and repeated every 8-12 days depending on the development of the infestation.

In sugar beet, the control of foliar diseases other than powdery mildew should be carried out as a preventive measure or at the latest at the time of the first symptoms. Depending on the weather conditions and the development of the disease situation, it is advisable to repeat the protection every 7 to 10 days.

In peaches and stone fruit, protection against Taffinella should be terminated by a wash spray at the latest at bud break to avoid the risk of scorch. Treatments against bacterial and fungal twig blight should be carried out in the autumn, at the beginning of leaf fall.

In plums, sour cherries and cherries, spraying against leaf blight and moniliaceous diseases can be carried out continuously during the growing season, according to the development of the infection. In quince, treatments with the product should not be continued after red bud stage.

In shell fruits, treatments should be started after the appearance of diseases and repeated every 14 days depending on the severity of the infection.

In grapes, treatments against grapevine peronospora should be started preventively, based on a forecast, around the 20-25 cm shoot stage and repeated every 7-14 days depending on the development of the infection. Residual treatments after cluster closure also have a positive effect on effective control of grey mould.

In vegetables, treatments against bacterial and fungal diseases in peppers, tomatoes, cucurbits, beans, peas, onions should be started preventively based on a forecast and repeated 2-3 times every 10-14 days depending on the development of the infection.
In sweet peppers, 2-3 additional control treatments are also necessary during periods of pest risk. In onions and peas, the addition of a wetting agent is necessary for good adhesion of the spray.
In crops authorised for use of the preparation, a higher dose is recommended in case of high infestation pressure.

For control of bacterial and fungal diseases (except powdery mildew), it is recommended to apply the product as a wash spray on woody stem crops in spring and autumn. In ornamental apple crops, after green bud stage, do not apply copper containing product until the fruit is waxy to avoid possible phytotoxicity. Spraying against bacterial and fungal diseases should be carried out preventively during the growing season and repeated as the infection develops. A phytotoxicity test is recommended before use. The amount of spray applied should be chosen according to the size of the foliage and the type of machinery used.
