Болезни суданской травы в условиях юга средней Сибири

Болезни суданской травы в условиях юга средней Сибири

Abstract

In conditions of the south of average Siberia the specific structure of illnesses of a Sudanese grass is revealed. It is established(installed), that the most widespread and nocuous diseases are root decayed, oblong spots(stains) on leaves, bacterial stem decay, red and black a bacterium. Seasonal dynamics(changes) of process of the basic diseases in various natural climatic zones is studied(investigated). The estimation of grades to a complex of the most widespread and nocuous activators is lead viewing plants. It is allocated and prepared for transfer on GSI perspective сортообразец К 57, possessing by the highest field stability to the basic diseases and economic valuable attributes.

В условиях юга средней Сибири выявлен видовой состав болезней суданской травы. Установлено, что наиболее распространенные и вредоносные заболевания корневые гнили, гельминтоспориоз, бактериальная стеблевая гниль, красный и черный бактериоз. Фитоиммунологическая оценка сортов показала, что наиболее высокой полевой устойчивостью к основным заболеваниям обладает сортообразец К 57, у которого индекс развития корневых гнилей в среднем за 2009 2010 гг. составил 7 %, бактериальных пятнистостей (красно бурого и черного бактериоза) 10,5 %.
