JOHNSON GRASS CONTROL AND ERADICATION

THE SUMMARY AND DATA COLLECTED IN A SERIES OF TESTS MADE DURING 1966 AND 1967 ON THE CONTROL AND ERADICATION OF JOHNSONGRASS ARE PRESENTED. IT WAS DETERMINED THAT A NEW EXPERIMENTAL CHEMICAL, CP 49814, HAS SYSTEMIC PROPERTIES AND IT MAY BE EFFECTIVE IN CONTROLLING JOHNSONGRASS. PRELIMINARY OBSERVATIONS INDICATE THAT MORNING APPLICATIONS OF DALAPON ARE MORE EFFECTIVE THAN THOSE MADE AT OTHER TIMES OF THE DAY. MONURON WAS CONSIDERED SUPERIOR TO ALL OTHER SOIL STERILANTS TESTED. OF THE FIVE GRASS SPECIES USED IN THE EXPERIMENT TO DETERMINE GRASSES THAT WOULD BE RESISTANT TO CHEMICALS APPLIED TO ERADICATE JOHNSONGRASS, THE RESEARCHERS FOUND THAT TALL FESCUE SHOWED THE GREATEST AMOUNT OF TOLERANCE TO DSMA (DISODIUM METHANEARSONATE). /BPR/
