The Movement of 2,4-dichlorophenyl methanesulfonate 35S in Plants

Movement of 2,4-dichlorophenyl methanesulfonate ³⁵S in plant roots was investigated using plastic containers which physically isolated portions of the plant root system. Results with bean and cotton plants showed that this compound can be absorbed in one part of the root system and distributed to other parts of the root system and also to the top of the plant. These tests confirm field observations of nematode control on roots outside a treated zone which indicated lateral movement of this compound in the roots. There was no evidence of its downward movement from treated leaves to stems or roots of cotton or beans.
