Grass weed competition with bread wheat in Ethiopia. 2: Prediction of grain yield loss and implications for economic weed control
(African Crop Science Society, 1996)
Two multi-year studies were conducted in Ethiopia to examine the effects of competition by the predominant grass weed species on bread wheat (Triticum aestivum L.). In the first experiment, the effects of four grass weed ...

Assessing the potential economic impact of Bacillus thuringiensis (Bt) maize in Kenya
(Academic Journals, 2011)
The Insect Resistant Maize for Africa (IRMA) project is currently developing Bt maize for Kenya. So far, Bt genes with resistance to Chilo partellus, Chilo orichalcociliellus, Eldana sacharina, and Sesamia calamistis, four ...

Evaluation of stem borer resistance management strategies for Bt maize in Kenya based on alternative host refugia
(Academic Journals, 2011)
Stem borers are the major insect pests of maize in Kenya. The use of Bacillus thuringiensis (Bt) technology is an effective way of controlling lepidopteran pests. However, the likelihood of development of resistance to ...

Bt-transgenic maize does not deter oviposition by two important African cereal stem borers, Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae)
(FacT Limited, 2008)
Objective: To assess Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) ovipositional responses on Bt (Event 216, containing the Cry1Ab gene) and isogenic non-Bt (CML ...

Combining ability of maize (Zea mays L.) inbred lines resistant to stem borers
(Academic Journals, 2011)
Ten inbred parents with varying resistance levels to Chilo partellus and Busseola fusca were crossed in a half diallel mating scheme to generate 45 F1 hybrids. The hybrids and five commercial checks were evaluated across ...
