Research Progress on Occurrence of Tobacco Black Shank and its Integrated Control
2015
Tobacco black shank is a soil borne fungi disease caused by Phytophthora parasitica var. nicotianae. In recent years,the large area occurence and wide spread of this disease has caused serious losses to tobacco industry in China,and threated its sustainable development. This paper discussed from the following 3 aspects: the occurrence process of tobacco black shank,the factors influencing the disease outbreak,and the integrated control method and effect. The paper suggested that biological control was the key development direction for preventing and controlling tobacco black shank in the future,more emphasis should be put on studying the pathogenesis and biological control mechanism of the disease. It also propost that systematic research should be carried out in combination with other control measures,so as to strive for exploring more feasible methods to prevent and control black shank disease.
