doi:10.11924/j.issn.1000-6850.casb17050114

Abstract

Abstract: In this paper, through the field plot experiment, we study the influences of reducing pesticide combined with pyroligneous acid and charcoal and foliage spraying pyroligneous acid on tobacco agronomic traits, yield, quality, disease, and economic effects. [Result]The results shows that: compared with complete use of pesticides, reducing pesticides combined with pyroligneous acid and charcoal and foliage spraying pyroligneous acid can improve agronomic traits during vigorous growth period and inhibit the occurrence of diseases, without obvious changes in yield, quality and output value. [Conclusion]Pesticides of 10-20% reduction combined with the considerable amount foliage spraying pyroligneous acid can assure tobacco normal growth and satisfying demand of yield, quality and economic effects.
