Copper chloride (or “Hom”, copper oxychloride, blitox, cupricol, zoltosan, cupritox) - refers to medium toxicity fungicides. It allows you to quite effectively deal with various plant diseases: with brown spotting, macrosporiosis, late blight, scab, curly, powdery mildew, rust.
Copper chloride (the average price is 16-18 rubles. For a package of 40 grams) does not have side effects on the treated plants. Contact requires protective measures (gloves, mask, goggles). The product, accidentally on the skin or eyes, should be immediately washed off with plenty of running clean water. For bees, the fungicide is low toxic, but it is better to isolate the hives before processing (with a shutter speed of at least 6 hours after processing).
Copper oxychloride is an analogue of Bordeaux fluid (substitute). A small minus associated with weaker retention on the plant is neutralized by a significant plus, which lies in the simplicity of the preparation of the working solution (the drug is simply mixed with water and quickly dissolved in it).
Plants are recommended to be sprayed only during the growing season.
Uses for protection against diseases
1. To protect against moniliosis and scab, six sprayings of the tree are required, the first spraying should be when pink buds appear (pinking), the second spraying should be done immediately after flowering, then - with an interval of 15 days (if necessary). Consumption rate - 35 gr. per bucket of water (average).
2. Against the curliness of the leaves of apricot, cherry, peach, plum and cherry, against coccomycosis and kleasterosporiosis, four sprayings will be required: the first - for swollen but not yet budged buds, the second - immediately after flowering, two more - with a two-week interval. Consumption rate - 35 gr. per bucket of water (average).
3. To protect the potato from macrosporiosis and from late blight, five treatments are required: during budding, the first treatment (for insurance), if there are signs of one of these diseases, the next treatment, the next three, if necessary, with a two-week interval. Consumption - 40 gr. on a bucket of water. In the treated areas, the larvae of the Colorado potato beetles also die, and mature insects of the treated plantings are wary.
4. To protect the crops (plantings) of onions or cucumbers from peronosporosis, the treatment is carried out only if signs of one of these diseases are detected. Reprocessing - after two weeks. Consumption - 40 gr. on a bucket of water.
5. In case of peronosporosis of hops, treatment is carried out when a disease is detected, then every 16 days if the weather is dry, and every 10 days if it rains.
The last treatment can be carried out three weeks before harvesting, regardless of the type of crop.
To increase the retention (stickiness) of the solution, it is recommended to add a small amount of 1% skim milk.
Copper chlorine is non-phytocidal for most cultures, but burns can subsequently occur in delicate, especially sensitive plants.
The drug is well combined with many pesticidamies and, when used wisely, shows very high efficiency. Shelf life of copper oxychloride, packaged in paper bags, is almost unlimited.
