Copper chloride - description, application

Copper chloride (or Hom, copper oxychloride, blister, cuprikol, zltozan, cupriotox) refers to fungicides of medium toxicity. It allows you to effectively combat various plant diseases: with brown spots, macrosporium, late blight, scab, curly, powdery mildew, rust.

Copper chloride (the average price is 16-18 rubles per packing in 40 grams) does not have side effects on the plants being treated. When contact requires protective measures (gloves, mask, glasses). The drug, accidentally got on the skin or in the eyes, should be immediately washed off with a large amount of running clean water. For bees fungicide is low toxicity, however, it is better to isolate the hives before treatment (with a minimum of 6 hours after treatment).

The drug copper oxychloride is an analog of the Bordeaux liquid (substitute). A small minus, associated with a weaker retention on the plant, is neutralized by a significant advantage, which lies in the simplicity of preparation of the working solution (the preparation simply mixes with water and dissolves rapidly in it).

Plants should be sprayed only during the growing season.

Methods of application for protection against diseases

1. To protect against moniliasis and scab, six sprayings of the tree are required, the first spraying should be with the pink coloring of the buds (porozovenii), the second - immediately after flowering, then - with an interval of 15 days (if necessary). The rate of consumption is 35 g. On a bucket of water (on average).

2. Against the curly leaves of apricot, cherry, peach, plum and cherry, against anticoccosis and kleisterosporiosis, four sprayings will be required: the first - with swollen but not yet budding buds, the second - immediately after flowering, two more - with a two-week interval. The rate of consumption is 35 g. On a bucket of water (on average).

3. Five treatments are required to protect the potato from macrosporia and from late blight: in the case of budding, the first treatment (for insurance), if there are signs of one of these diseases, the next treatment, three subsequent ones, if necessary, with a two-week interval. Consumption - 40 gr. On a bucket of water. On the treated areas, the larvae of the Colorado beetles also die, and the mature insects of the treated plantations are cautious.

4. To protect the crops (landings) of onions or cucumbers from peronosporosis, the treatment is carried out only when the signs of one of the named diseases are revealed. Repeated treatment - after two weeks. Consumption - 40 gr. On a bucket of water.

5. When peronosporoze hops treatment is carried out in the detection of the disease, 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 the harvest, regardless of the type of crop.

To increase the retention (stickiness) of the solution, it is recommended to add a small amount of 1% skimmed milk.

Copper chloride for most of the crops is nonphytocidal, however, tender, especially sensitive plants can subsequently be burned.

The drug is well combined with many pesticides and with reasonable use shows very high efficiency. The shelf life of copper chloride, packed in paper bags, is almost unlimited.
