Abstract:
... Systematic rat control was developed in oil palm plantations in the 1960s and 1970s by comparing bait mixtures and application techniques mainly for anticoagulant poisons, in trials with related ecological studies. Rattus tiomanicus populations of 100-600/ha were estimated in plantings of a range of ages and localities, and numbers fluctuated slowly within these limits in a single plot without con ...

Abstract:
... Transgenic plants are produced via Agrobacterium mediated transformation and other direct DNA transfer methods. A number of transgenes conferring resistance to insects, diseases and herbicide tolerance have been transferred into crop plants from a wide range of plant and bacterial systems. In the majority of the cases, the genes showing expression in transgenic plants are stably inherited into the ...

Abstract:
... Corn earworm (CEW), Helicoverpa zea (Boddie), is a major economic pest of corn both in the US and worldwide. The primary means of controlling CEW on corn is to use host plant resistance because chemical control is costly and inconsistent. The objective of this study was to identify new sources of CEW resistance genes from the Germplasm Enhancement of Maize (GEM) germplasm with either 25% or 50% tr ...

Field studies were established at two locations in Missouri to determine Amaranthus rudius (common waterhemp) control by single or multiple pre-emergence and/or postemergence herbicide strategies in glyphosate-resistant corn and soybean. The corn study assessed five herbicide strategies: pre-emergence alone; mid-postemergence alone; early postemergence followed by mid-postemergence; pre-emergence ...
