Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

В статье приведены результаты мониторинговых обследований в Южном, Юго-Восточном и Центральном регионах Казахстана диких посадок яблони Сиверса на пораженность болезнями. В ходе проведенных исследований установлено, что в обследованных регионах встречались такие болезни, как парша (Fusicladium dendriticum), монилиозная плодовая гниль (Monilia fructigena), цитоспороз (Cytospora capitata), мучнистая роса яблони (Podosphaera leucotricha), ржавчина (Gymnosporangium juniperinum Mart.) и пятнистости различной этиологии. В засушливый 2021 год на дикоплодовых насаждениях проявление парши, монилиозной плодовой гнили, различных видов пятнистостей и ржавчины было слабым. Основной болезнью в 2021 году была мучнистая роса, которая паразитировала на угнетенных засухой деревьях.

In the drought period of 2021, the manifestation of scab, moniliose fruit rot, various types of spotting and rust on wild fruit plantations was weak.
