Economics Of Summer Weed Control., T. Piper
Experimental Summaries - Plant Research
Aims: To test various chemical options for summer weed control; measuring their efficacy, the amount of soil moisture conserved, and follow-up crop yield. A full season cost-benefit could then be produced. Summer rains were widespread in 1990, and summer weed sites were plentiful.

Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd
Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd
Experimental Summaries - Plant Research
Trials : 88BY26, 88PE34, 88MD35
Control of Rhizoctonia solani infection of potato stems and daughter tubers was demonstrated by preplanting applications of tolclofos-methyl (RIZOLEX TM) to either cut or round seed tubers. Yield of tubers from cut seed treated with Rizolex was increased over that of cut seed cured before planting bu not when seed was cut and planted the same day. Crops grown from round seed treated with Rizolex yielded higher than from untreated round seed.
Surface sterilization of seed tubers with Sodium hypochlorite was effective in reducing stem damage but not in reducing daughter tuber sclerotes. This indicates …

Experimental Summaries - Plant Research
86KA71, Pasture legumes improve the feeding value of summer pastures in a mediterranean-type environment by maintaining the protein intake of grazing animals over the dry summer period, much of which comes from the ingestion of legume burr (A.D. Wilson and N.L. Hindley, 1968). Some of the most important species of pasture legumes to have been released commercially are Trifolium subterraneum (sub.clover), Medicago truncatula (barrel medic) and Medicago polymorpha (burr medic) (D.B. Purser, G.B. Taylor and W.J. Collins, 1987). What little information is available on the feeding value of these species suggests that barrel medic pod (H. Brownlee, 1973) and dry …
