Residue Trials, Herbicide Incorporation And Leaching Of Chlorsulfuron, T Piper

Experimental Summaries - Plant Research

Residue Trials: Breakdown rates have been established for trifluralin at Wongan Hills and Avondale over the past two seasons. The decay curve follows a hyperbolic curve rather than the expected exponential curve with constant half life, probably due to the considerable loss of chemical by volatalization in the first few days, before biological decomposition takes over as the main breakdown factor.

b) Herbicide Incorporation. Du Pont Zl96 fluorescent orange powder at 30 g/m2 could be readily seen when illuminated by 400 yw/cm2 of 365 nm UV radiation, and was successfully photographed on Ektachrome 400 ASA film with a 4 sec. …

Clover Scorch Fungicide Trials, Cercospora Leaf Spot Of Sub Clover, Lupinosis Control., A Bokor

Experimental Summaries - Plant Research

82 AL 60, Clover scorch fungicide trials. Aim: Test a range of new fungicides for clover scorch control in comparison with Benlate. Comments: DPX 164-2 and Bavistin gave excellent disease control even at the lower rate. Benlate and Tilt were still satisfactory but control was not as good at the lower rate. Bayleton and Baycor gave some disease control but only at the higher rate. Cercospora leaf spot could be found on most plots with careful search. Economically important damage has occurred only on a few plots. Pseudopeziza leaf spot was notably absent during this season compared with others. 83 …

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
