The Impact Of Beneficial Organisms In Corn Agroecosystems, Callie Rosalind Braley
The Impact Of Beneficial Organisms In Corn Agroecosystems, Callie Rosalind Braley
Doctor of Plant Health Program: Dissertations and Student Research
Corn is one of the world’s, and Nebraska’s, most important crops. Millions of acres are planted to corn each year in the Cornhusker State. However, each year there are a plethora of arthropod, weed, and microorganism pests that rob farmers of reaching their maximum yield potential. There are many options available to manage these pests in corn agroecosystems, but one option is often underutilized: beneficial organisms. For each pest, there are a variety of natural enemies that can assist in mitigating the damage caused by pests.
Many beneficial organisms exist, and they can be grouped by the type of pest …
Impact And Liberty Rates And Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Impact And Liberty Rates And Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of the study was to compare Impact (topramezone), Liberty (glufosinate) and a premixture of the two herbicides (Sinate) for efficacy in corn. Rates for each herbicide were 0.75 and 1.0 oz/a for Impact, 22 and 30 oz/a for Liberty, and 21 and 28 oz/a for Sinate. Impact and Sinate, each at the high rates, and Status plus glyphosate provided the best kochia control for corn late in the season. These treatments, along with the low rate of Impact controlled crabgrass the best. Status was also the best treatment for Russian thistle, Palmer amaranth, and green foxtail control. The …
Outlook Alone And In Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Outlook Alone And In Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of the study was to compare Outlook (dimethenamid) alone and in various tank mixtures for season-long weed control in corn. Kochia control with most herbicides was 95% or more late in the season. However, Russian thistle control did not exceed 83% with any herbicide tested. Palmer amaranth control at 59 days after the postemergence treatments was similar among all herbicides, while green foxtail control was 93% or more with each treatment. All herbicides increased grain yields relative to the untreated control, but corn treated with Outlook or Verdict alone yielded less grain than the best yielding plots.
