And one more attack of seeds - black cancer. In this case, a black spot under the top translucent film of the cortex appears first - i.e. The disease increases as if from the inside of the bark, and the film remains untouched outside. Then the ulcer grow up, the bark is as if falling inside, and then the outer translucent peel is burst.
I will tell you about measures to combat this insidious disease. Infection with black cancer goes in Mainly through nurseries, where to deal with this disease is extremely difficult due to the huge number of seedlings.
Therefore, the landed seedling, bought in the nursery, should be carefully inspecting the next year if black spots appeared under the top of the cortex. Watch all seedlings need a year 3-4 until it becomes clear that there are no diseases. If the disease still appeared, you need to do the following. Take a knife with a very well sharpened tip and cut all sick fabrics on the crust to a healthy place. Sometimes it seems that you have already achieved a healthy fabric, but unnoticed brown bodies can reduce the entire operation. Therefore, until a purely green bark appears, do not stop the operation. Then it is necessary to clean the wood in the wound, cutting off its top layer.
H The most important thing - none of the pieces of bark and wood from the wound should fall to the ground. Everything needs to be collected and burn.
Next, the wound must be processed. You can do this as described in the literature. I do it an ancient way. Two parts of Nigrol and 1 part of well-sashed ash are taken. All motorists and tractor drivers know what nigrol is. All this is thoroughly mixed. Then this mixture is embossing the place of operation. Just do not smear a thick layer, because in the heat all this will flow. The ash in tanks with a mixture quickly settles, so it must be mixed before each shutter.
