Of the 333 introductions tested, 23% scored 3.0 or less indicating a high level of resistance. Bluegreen aphid screening: Two hundred and twenty four randomly selected subterranean clovers from all Western Mediterranean collections were tested for resistance to BGA in Nov/Dec of 1983. The susceptibility of annual legumes to Bluegreen aphid. Red legged earth mite screening: Results of two preliminary experiments to develop techniques for mass screening for RLEM resistance in subterranean clover were reported last year. …

Sorrel, Dicamba Soil Residual Effects, Glean, Veldt Grass, Declared Weeds Blackberry, Pattersons Curse, Penny Royal, J Moore

Experimental Summaries - Plant Research

CONCLUSIONS This trial has confirmed the field observation that 2,4,5-T whilst giving good initial control of Pennyroyal, fails after a number of years. Round up has a far longer term effect. This can only be attributed to a more complete initial kill as both herbicides are essentially non residual. Further work needs to be conducted on Round up in combination with soil residual chemicals or multiple applications to overcome the problem of reinfestation from seed reserves. 81A1 -01
