Editor’s note: This commodity is from the athenaeum of the MSU Crop Advisory Team Alerts. Check the characterization of any pesticide referenced to ensure your use is included.
BASF appear a new use characterization for Headline as an in-furrow at-planting appliance for amoroso beet as able-bodied as blah and soybeans. The characterization can be beheld here. I accept conducted no trials on this appliance timing at MSU or, as far as I am aware, none accept been conducted at Michigan Amoroso Company according to Ralph Fogg. BASF has, however, sponsored a analysis for 2009. There were no abstracts accessible from the APS web armpit (Fungicide and Nematicide tests or Bulb Disease Management Reports). At this stage, although I accept no acknowledging abstracts to the contrary, it would be difficult for MSU to angle by this appliance timing although it may able-bodied be effective.
Crown and basis rot was astringent in abounding operations in 2008. Dr. Linda Hanson appear an alternation with the clay bane Rhizopus that affronted the problem. In trials conducted at the MSU Bean and Beet Farm, Saginaw, MI; amoroso beet (Beta vulgaris L., cv. 5534N) was PAT-treated and buried on April 21 and a fungicide timing abstraction initiated. A abounding address is accessible on the Bean and Beet Annual Address 2008.
The clay damp and temperature altitude added development of acme and basis rot. Quadris activated in channel at burying had decidedly lower bulb stand, 25 DAP in allegory to the non-treated control. No treatments had decidedly greater bulb angle in allegory to the non-treated control. Proline activated at GS 4-6 additionally had decidedly lower RAUEPC. The beggarly allotment of asleep and dying amoroso beets 127 DAP in the non-treated plots was 72.8 percent. Some treatments such as Quadris activated at GS 6-8 gave outstanding ascendancy of acme and root. Proline and Quadris activated at GS 4-6 additionally decidedly bargain acme and rot in allegory to the non-treated control. No added analysis timings were effective. Quadris activated at GS 2-4 and 6-8 and Proline activated at GS 4-6 bargain accident of acme and basis rot of actual plants in allegory to the non-treated control. Quadris activated at GS 4-6 and 6-8 bargain severity of acme and basis rot of actual plants in allegory to the non-treated control.
Dr. Kirk’s assignment is adjourned in allotment by MSU’s AgBioResearch.
