Effects of napropamide on microbiological characteristics of tobacco rhizosphere soil and its dissipation

Knowledge of microbiological characteristics in the plant rhizosphere is essential for understanding the fate and transport of agricultural chemicals in soils. The present study was conducted to investigate the effects of an acetanilide herbicide napropamide on microbiological characteristics of tob...
