Influence of Caging and Pesticide Drenches on Yield and Persistence of Red Clover, Trifolium pratense L.1

K.E. Zeiders, R. C. Newton and J. H. Graham2

Drenching of field plots with insecticides resulted in a highly significant increase in yield in each of three harvest years. Fungicide drench had little or no effect on yield and was discontinued after the first harvest year. A significant increase in yield due to caging was observed in 1966 and 1967. Effects of both insecticides and caging on stand survival were highly significant in 1967, but nonsignificant in preceding years. Caging decreased the incidence of virus disease and foliar insect damage, and the percentage dry matter of forage in both check and insecticide-treated plots. External root rot was severe on all surviving plants after 39 months regardless of treatment. Insecticides favored root growth as evidenced by larger crown diameters.

Key Words: Dry matter production • Stand survival • Soil fumigation • Insecticides • Fingicide • Rootfeeding insects • Root rot
