Abstract
Aldicarb (2 methyl thio) propionaldehyde-0-(methyl carbamoyl oxime), a systemic insecticide treatment altered the quantity and the quality of the extracellular polysaccharides (slime) produced by Pseudomonas solanacearum. Although 5 ppm (normal dose) aldicarb treatment reduced the quality of polysaccharides produced by the cells, the incorporation of /sup 14/C (glucose) label and the reducing sugar contents was higher than the other treatments. Chromatographic analysis of the hydrolysed polysaccharides showed that aldicarb treatment altered their qualitative composition also. The extracellular polysaccharides produced by the pathogen treated with 5 ppm aldicarb caused wilting of tomato seedlings earlier than others, indicating thereby, that the wilt inducing factor in the slime was altered by the pesticide treatment. The limited translocation of the /sup 14/C labelled polysaccharides in the wilted seedlings indicated mechanical blocking of the vascular system of the plants.
