Depuis la commercialisation du coton Bt, question de pureté des semences utilisées par les producteurs est peu abordée, encore moins en relation avec l’analyse système semencier dans le pays concerné. Cet article étudie cas Burkina Faso 2015, où couverture surfaces transgénique deux gènes Bt restée partielle, jusqu’à sa suspension décidée même année. En se basant sur seuils présence retenus l’é...

The widespread planting of corn genetically modified to produce Bacillus thuringiensis endotoxin has led to speculation that pollen from these fields might adversely affect nearby nontarget lepidopterans. A previous study of Bt corn engineered with Monsanto event 810 failed to detect an effect of pollen exposure on the black swallowtail, Papilio polyxenes, in either the field or the laboratory....

Since the first commercial release of a bioengineered crop in 1996, planted acres of enhanced crops have increased steadily each year. Yet, public perceptions and knowledge of the benefits of this technology have not kept pace with grower demands for the new tools. Additionally, global regulatory infrastructure and capacity to evaluate and approve the release and import of these products has be...

BACKGROUND Residents of Anniston, Alabama, live near a Monsanto plant that manufactured polychlorinated biphenyls (PCBs) from 1929 to 1971 and are relatively heavily exposed. OBJECTIVES The goal of this study was to determine the relationship, if any, between blood pressure and levels of total serum PCBs, several PCB groups with common actions or structure, 35 individual PCB congeners, and ni...

The results of a 90-day rat feeding study with YieldGard (YieldGard Rootworm Corn is a registered trademark of Monsanto Technology, LLC.) Rootworm corn (MON 863) grain that is protected against feeding damage caused by corn rootworm larvae are presented. Corn rootworm-protection was accomplished through the introduction of a cry3Bb1 coding sequence into the corn genome for in planta production ...

Laboratory studies were conducted to investigate the subacute effects of transgenic Cry1Ab corn leaf material containing Bacillus thuringiensis (Bt) protein on the terrestrial isopods Trachelipus rathkii and Armadillidium nasatum. Survival and growth were measured for eight weeks in isopods fed leaf material of two Bt11 corn varieties, two Monsanto 810 (Mon810) corn varieties, and the isolines ...

the alternative use of non-selective herbicides in different years will reduce the possibility of weeds resistance to herbicide by avoiding the crops constant exposure to herbicide selection pressure. the photoperiod-sensitive genic male sterile (pgms) rice with herbicide resistance will be convenient to the mechanization of hybrid seed production and weed control. in order to develop double he...

Replacement trees were planted in the transgenic field plot. A total of 124 plants in the plot now includes 3 Su-2 clones with Bt (~IA(c» and Kan, 3 similar control clones without Bt, 10 Su-2 clones with Kan and GUS, 8 SF-delta clones with Kan, and 2 untransformed control clones (Su-2 and SF-delta). Seven trees (representing 3 clones) flowered in their second season in the field. Polymerase cha...

A field study was conducted on sandy clay loam soil to evaluate the impact of row spacing and N application method on the productivity of maize (Zea mays L.). The experiment was conducted using four row spacings (60 cm spaced single rows, 90 cm spaced double row strips, 90 cm spaced single rows and 135 cm spaced double row strips) and two methods of nitrogen (N) application (broadcast and band ...
