The process of introgression between a transgenic crop modified for better agronomic characters and wild relative could lead potentially to increased weediness adaptation the environment species. However, formation hybrid progeny be associated with functional imbalance low fitness, which reduces risk gene escape establishment species in field. Our work compares fitness components parents different types backcross sixth generation hybrids oilseed rape (Brassica napus, AACC, 2n = 38) resistant...
The effect of two‐component rice cultivar mixtures on the control blast disease was studied in three different experiments under rainfed upland conditions Madagascar Highlands. involved a susceptible (either or very susceptible) and resistant mixture arrangements (random row mixtures) with proportions (50, 20 16·7%), which were compared to grown pure stand. these incidence severity leaf panicle measured weekly, yield components at harvest time. more efficient reducing proportion 16·7%...
Magnaporthe oryzae is the fungal plant pathogen that causes rice blast. The sources of primary inoculum and overwintering mode fungus remain largely unknown. effect residues on onset blast epidemics potential for survival M. in were studied upland conditions Madagascar. Blast disease was observed a 3‐year field experiment three treatments: with either infected or uninfected soil surface, without residues. Leaf incidence significantly higher treatment than two other treatments at early stages...
In response to the extensive development of upland rice on hillsides Madagascan highlands, alternative cropping systems based conservation agriculture have been recommended halt declining soil fertility and limit erosion. To assess efficiency these in limiting blast disease measure their yield performance, an experiment was set up 2003 at Andranomanelatra (1640 m a.s.l.) highlands. The crop planted every second year following oat ( A vena sativa ) after common bean P haseolus vulgaris ),...
Bacterial leaf streak (BLS) caused by Xanthomonas oryzae pv. oryzicola is an important disease of rice. BLS prevalent in Asia and West Africa, where it was first reported Nigeria Senegal the early 1980s (4). Recently, molecular analysis strains from Mali (2) Burkina Faso (5) further confirmed presence Africa. In Madagascar, symptoms were Buddenhagen but causal agent not unequivocally determined (1). To confirm Buddenhagen's observations using modern typing tools, we surveyed several rice...
Summary Weed beet populations growing in each crop of the arable rotation could be a relay for gene flow from adjacent transgenic herbicide‐resistant sugarbeet. In this study, weed growth and reproduction were assessed under several conditions which found rotation: various densities (ranging 1 to 120 plants m −2 ) crops (winter wheat, spring barley, pea, sugarbeet, maize, ryegrass). Measurements carried out both on life‐cycle dynamics (bolting time, time flowering onset, flower opening)...
We review interactions between crop protection practices (developed to control plant pathogens and invertebrate pests) human fungal infectious diseases. Unlike viral, bacterial parasitic infections, infections in humans are usually only superficial healthy individuals, but can become invasive pose serious risks immunosuppressed individuals. Although their global impact is less than that of other diseases, still public health issues. For instance, the use synthetic agricultural fungicides,...
Evaluating cropping systems depends on the perspective and scale considered. An agronomic point of view is often considered with assessment impacts system at field scale, or an economic consequences implementing a farm. Tools have been developed to enable more integrative systems. This case MASC® model which, using multicriteria evaluation, estimates sustainability from environmental, social perspectives. MASC-Mada was specifically for upland in Madagascar. It has used compare conservation...
