On the territory of our country, gooseberries are quite popular. Diseases, unfortunately, do not bypass it, and in order to get a good harvest, you need to take care of eliminating this scourge.
Main types of diseases
All diseases of these garden bushes can be conditionally divided into two types: verticillium drying and wilting of branches and shoots and a variety of spotting. Consider them in more detail.
How does gooseberry wilt and wilt affect? Diseases of this kind affect the branches and leaves of the bushes. In the first case, wilting of the foliage is observed, which at the same time acquires a yellow color. It does not crumble from the branches, but remains attached to them. The second name of the gooseberry disease speaks for itself. Branches and shoots of bushes dry out, cracks appear on the bark, between which black dots are clearly visible - pathogens.
As already mentioned, various gooseberry spots are also striking. Diseases of this type can be attributed to one of five types of pathogens:
1. Spotting black, or alternaria - on the leavesbushes appear gray-black spots with a velvety coating of olive color of a relatively large size.
2. Brown spotting - the appearance on the leaves of brown spots with a small black bloom.
3. Ascochitous spotting - spots of light gray or white, around each of which there is a brown border, rounded, sometimes with black dotted pycnidia.
4. White spotting (septoria) - the appearance on the foliage of shrubs of small angular or rounded brown spots, around which there is a red-brown border. Over time, these spots become lighter, but the border remains just as bright.
5. Anthracnose spotting - can appear not only on foliage, but also on branches and petioles. Represents small depressed rounded spots of dark brown color.
It is necessary to highlight some more points regarding the spotting that gooseberries suffer from. Diseases of this kind have characteristic features: spots, sporulation and pads. All of them are located on the top of the leaves. However, if light spots are visible from above, and below there are orange-colored sporulation pads, then this is already rust. Moreover, it spreads quite interestingly.
Other diseases
If sedge grows next to bushes, gooseberry rust may appear on gooseberries, if Siberian cedar or Weymouth pine, then columnar rust. Thanks to this neighborhood, the causative agent of the disease has the opportunity to overwinter on sedge orpine, and in the spring to infect young gooseberry leaves.
Sometimes you can see a thin black film on gooseberries, this is nothing but a disease called black. Another ailment is also known - the sphere library, also called powdery mildew. It is a plaque on the gooseberry. If the plant is severely affected by this disease, then drying occurs on the young shoots in the upper part, but the pathogen hibernates under the bark.
All the diseases that were listed above belong to the fungal category, but viral diseases are also found in shrubs. Among them is the edging of the veins. The plant has a pale yellow border on the first and second order of veins. Plus, chlorosis occurs on the leaves, after which they quickly lose their shape and become wrinkled.
Fight disease
There are not so many drugs used to combat various gooseberry diseases. This is copper sulfate, which helps get rid of septoria and other types of spotting, cumulus saves from powdery mildew, anthracnose and ascochitosis, as well as Bordeaux mixture - from rust, septoria and anthracnose.
Some gardeners are trying to use drugs such as Topaz and Fundazol to combat gooseberry diseases. This decision is wrong, since these products can only be used to treat blackcurrant. However, if there is a whole gooseberry nursery on the site, then it is possible to use Fundazol to get rid of verticillium wiltgooseberry bushes.
