Research on phytotoxicity control of tobacco herbicides residues

Tobacco is more sensitive to herbicides and express phytotoxicity symptoms such as dwarfing, growth retardation, malformation and yellowing of old leaves with widespread application of herbicides, which affect tobacco quality and yield seriously. The environmental factors affecting the degradation of herbicides, the typical phytotoxicity symptoms induced by common herbicides, and several methods to remediate herbicide residues were reviewed in this artical. Traditional methods (soil plowing, herbicides rational combination, irrigation-drainage method, oil neutralization, pharmacy remedy, and animal repair), safeners application, plant growth regulators, cultivating resistant gene and microbial degradation in the treatment progress of herbicide residues were pointed out, which might provide evidences for the further research of herbicides phytotoxicity solution and promote the development of new methords for herbicides residues in the tobacco field.
