Observations show that the severity of jaundice increased at week 2 until week 12 ,while the plants that has treated with PGPR has resistance to infection than plants whose are not treated with PGRP , that indicates the PGRP have ability to increase plant resistance for infection by leaf curl disease whose transmitted by white fly for plants, from other side the limiting edge also has shown ability to protection the plant from infection by insect and when we use corn like limiting edge ( pembatas pinggir ) the plants of chili has shown a low average of infection comparing with control and other limiting edge ( pembatas pinggir ) , even the plants are treated by PGPR without to use limiting edge has resistance to infection more than plants are not treated by PGPR without limiting edge ( pembatas pinggi ) .
