Questions about the fight against diseases and pests arise constantly. Often the answer is in the literature or by the neighbors, but no, no yes, and you will chase something in an unknown. I am engaged in gardening since 1978, when we have frozen all the gardens. Grandfather made the stump and plant a new garden. So I also bought to this case. Now I have a large garden that occupies approximately 45 acres. In it, there are over 20 types of fruit crops. And for each type - big Number of varieties. Therefore, I do not know about the difficulties of each culture. And I am writing to people, solving this series of problems, did not lower your hands from the inability to find a way out.
I have been engaged in pears for 15 years. For the North-West, this culture is new. I have a test now over 30 varieties. And every year at the beginning of summer on some young plants (mostly 2-4-year-old), the edges of the leaves on young green escapes. Then for several days and the shoots themselves gradually black, lose the tour. And breathe almost until last year's growth. Next, only the trunk is growing, and the tops of the shoots do not grow. What I just did not! And sprayed from diseases, and loose, and fertilized, and stimulated. Against pests, however, did not undertake anything, since they could not be found for 13 years. It does not have a relationship with a pear gallopage. With this tick once my 10-year-old pear was amazed - the leaves are also black too. After a single spraying, the tick died.
Attempts to find in the literature at least mention about this phenomenon or illness did not give anything. Distribution on exhibitions and markets also did not help. Nobody knew anything. 13 years of searches passed. And 2 years ago, when I almost got up with the fact that I could not solve this problem (the pears really do not grow!), Providence sent me a randering.
It was in mid-June, about 11 pm, in a white night. Pearing a pear tree with a height of about a meter, I could glimpse something strange on it. Approached closer. I look: Sit on the tops of green shoots some beetles devour the leaves. It is on my own pear! I have never seen such beetles. Fully green, under the color of young leaves, the magnitude of times one and a half more ladybugs, and some angular. I extended my hand to catch at least one, and they swallowed and disappeared somewhere. No found in the grass failed. Nutro I went to inspect the seedling. The edges of young sprayed leaves have already begun to be black, and the top of the green escape has lost the tour. And then everything is as always. More I have never seen these zhukov, although the consequences of their activities are watching every year.
Looks like they lead a nightlife - in the afternoon I would find them a long time ago. I assume that they are injected into the sheet, so the leaf subsequently drawn. After all, if the sheet eats ordinary caterpillars or other insects, the leaves do not black, just left the hole.
Our house is in a small village, in the midst of huge forests and fields. Pear for our zone culture is new, and in the wild there is no one here. I think some kind of zhukov "retrained" and eats now at the same time and pear. Although how to know, maybe they were brought with pear seedlings. How fight unknown beetles? The question is complex. Do not sleep at night, or what? Next season, I will try to attach sticks impregnated with creosote to seedlings, frozen from sleepers to scare away insects by the smell. I do not know whether it will help.

Can this bacterial burn?
Very similar to the description. Same faced with such a problem - on the boost and nuts (Greek), what to do - I do not know!
I have the same. Bought at the station of gardening in 1995 two pear saplings. Summer grew normally. The next year, the tree began to grow well, but in mid-June they began to root and change the color of the leaves, only on new, green, shoots. Then at the beginning of July they began to dry, pereknesh then black. Then he painted almost completely and the new shoots themselves. The leaves were dying, like black tea, did not appear in winter. The next year everything happened. There was no flowering. So she lasted 6 years. Trees did not grow up, only thickened the trunk and increased bush. I had to reverse. In 2008, again bought seedlings at the gardening station. I planted for a new place 30 meters from the old one. A year later, the same thing began. Other trees and bushes do not ill, pests are not visible in the pest, the soil is normal, groundwater at a depth of 6 meters, everything else grows perfectly. On cancer and bacterial burns like it does not seem. So what is it? How to treat?
Received a cottage (1986). Posypipped fruit trees, including 2 pears. It would have begun. But then the growth stopped and the leaves of the pear began to black. Grushi grew in the place where there was a big shadow from the Garden House. Another place (5-6 meters), rooted, began, the leaves are not Cherneli. This time is one of the pears died (in the winter it was crushed from a large number of snow), the second of this year cut off, went new shoots from the trunk. Left several old branches).
