Year on year is not necessary, and the fertile season can be replaced by a painful and poor harvest. It is unpleasant to observe how on lovingly grown plants there suddenly appear defeats and signs of ill health. And the sooner it becomes possible to understand why the leaves curl at the currant, the earlier one can take action.
Why do the currant leaves blush and curl?
The reasons for this phenomenon can be a few matter either in sickness or in pests.
- Buckwheat rust. Most of all currant varieties of this disease are susceptible to black currant - it twists the leaves, there are reddish pads under which spores develop. On cultural plants, spores fall with the wind, if there are sedge fields nearby.
Methods of combating glassy rust:
- first of all - cut the sedge at a distance of 200 meters from the garden;
- choose currant varieties that are resistant to this disease;
- Spray the bushes with a 1% solution of Bordeaux's liquid (the first time during the opening of the leaves, the second at the time of detachment of the buds, and the third immediately after flowering);
- treat with bio-preparation "Fitosporin";
- all the affected leaves tear off and burn out the patch.
Methods of fighting aphids:
- tear off the diseased leaves and burn them;
- treat the bushes with tobacco infusions and wood ash or infusion of onion husk , while try to wet the bottom of the leaves abundantly;
- Fight not only with aphids, but also with ants, because these two problems are inextricably linked.
