Sodium Sulfanilate(Ⅰ)and sulfanilic acid (Ⅱ)were found to penetrate readily into the leaves when sprayed on groundnut plant,the amounts taken in being 0.1352 and 0.0772μg/mg dry wt.of leaf respectively.The distribution pattern of I within the plant was rather uniform. The amounts of the chemical in the upper,middle and lower leaves were 0.1043, 0.1070 and 0.1024μg/mg dry wt.of leaf respectively on the 8th day after spraying and 0.0972,0.0797 and 0.0765μg/mg dry wt.of leaf respectively on the 15th day.The acropetal translocation was demonstrated to be very prominent with I in groundnut plant. But merely a limited basipetal movement was shown,the amount recovered in the roots being only 0.25% of the chemical applied to leaves.However,the ability to move down-ward to a short distance was shown for I and the transverse translocation was found to be relatively more significant.Therefore,it is not necessary to have a highly uniform spray during the application of the chemical.The amounts of I determined in plants growing from seeds sown right after and 3 days after dressing were 2.4628-2.6200 and 1.8654-1.8664μg/plant respectively. It is,therefore,recommended to sow seeds on the day of dressing but not to store the treated seeds intentionlly when a seed treatment is claimed to control leaf rust of groundnut. Sodium sulfanilate was found to penetrate through roots and translocate to foliages in the above-ground parts of groundnut plant readily when applied to soil. Surfactants were shown to faciliate the penetration. The solution of I with an addition of "Tween 80"(Ⅲ)or colloidalsurfur containing 50% of sulphite by product of pulp)(Ⅳ) were found to promote the readiness of the movement of the chemical in soil. In a layat of "20 cm of soil, the retention rates of the chemicals were found to be 3.41% 2.58% and 2.74% for Ⅰ,Ⅲ and Ⅳ respectively. In the soil drench experiments on the control of leaf rust,it was found the efficacies were 59.45% and 95.52% for Ⅰ and Ⅳ respectively.It was thus further shown that the formulation of the combination of "di-xiu-na" and colloidal sulfur is very reasonable.
