Evaluation Of Repellent Seed Treatments And Effects On Early Corn Performance, Ann E. Koehler, Ron J. Johnson, Orvin C. Burnside, Stephen R. Lowry

Department of Agronomy and Horticulture: Faculty Publications

A combination of field, field enclosure, and germination chamber studies was used to evaluate the effects of methiocarb [3,5-dimethyl-4-(methylthio)phenol methylcarbamate] and thiram (tetramethylthiuram disulfide) repellent seed treatments on early corn performance. The thiram treatments used (0.08, 0.4,0.8,0.5,1.25, and 2.5% active ingredient by corn seed weight) had negligible effects on germination/emergence time or on com plant heights. The thiram treatments never reduced stand counts in comparison to controls, but apparently increased stand counts in some trials, particularly under wet conditions. The methiocarb treatments evaluated (0.5, 1.25, 2.5, and 5.0% active ingredient by corn seed weight) had only occasional effects on early …

A Guide To The Identification And Control Of Insect Pests In Maize Crops Grown Int He Ord River Irrigation Area, S.E. Learmonth

Grain and other field crops published reports

The importance of insect pests in Ord maize crops is seasonal both in terms of their abundance and the species present. It is therefore desirable that the main pests of maize can be recognized quickly and appropriate action taken to avoid crop loss

In this guide, all of the common insect pests likely to be encountered in Ord maize crops are described. Photographs of only the more important of these and some of their natural enemies are included. Any insect that cannot be readily identified may be taken to the office of the Department of Agriculture.
