Update on June 11, 2009
All treatments went out according to plans. RWW cores were taken on June 5, 2009, -- 3 weeks after establishment of permanent flood. The data are presented in the corresponding graph. RWW core data is an average of 10 cores/field, with the exception of the Dermacor field, which was an average of 9 cores per field. It is estimated that for each RWW larva/core, there is a .5-1.5% yield loss.
All of the insecticides provided some level of control. Control ranged from 76 to 100%. The untreated check field had an average of 9.2 RWW larvae per core. Karate Z pre-flood and Karate Z pre-flood followed by Mustang 1.5ec on fertilizer post-flood provided best control with no RWW larvae detectable in cores. This was closely followed by Dermacor X-100 with an average of 0.2 RWW larvae per core. The field treated with Mustang 1.5 ec post-flood had an average of 1.6 RWW larvae per core, while Trebon had an average of 3.1 RWW larvae per core. We will now compare these results to the other 5 locations in this test.
Yield data will be reported when they are gathered at the end of the season.
