AIMS To evaluate the cultivable mycobiota from agricultural soils exposed to pesticides, the aflatoxigenic capacity of Aspergillus section Flavi strains and the effect of glyphosate on lag phase and growth rates of native nontoxigenic Aspergillus flavus under different water potential (MPa) conditions on soil-based medium. METHODS AND RESULTS Culturable mycobiota analysis from different agric...

Background: The herbicide RoundUp® became widely used in agriculture in the mid-1990s. Current populations of the crop weed Ipomoea purpurea exhibit both resistance and tolerance to RoundUp, which are two types of defence that have previously been shown to have a genetic basis in this weed species. Questions: Did the genetic basis of RoundUp defence antedate the introduction of RoundUp? If so, ...

Jhala, A. J., Malik, M. S. and Willis, J. B. 2015. Weed control and crop tolerance of micro-encapsulated acetochlor applied sequentially in glyphosate-resistant soybean. Can. J. Plant Sci. 95: 973 981. Acetochlor, an acetamide herbicide, has been used for many years for weed control in several crops, including soybean. Micro-encapsulated acetochlor has been recently registered for preplant (PP)...

I n recent years, we have seen an exponential increase in the use of herbicides, such as RoundUp, that contain the active ingredient glyphosate (1). Glyphosate kills plants by inhibiting the production of aromatic amino acids in the shikimate pathway (2). This herbicide is popular because it works well and has been shown to be relatively ecologically ‘‘safe’’; it has low toxicity to animals, in...

Background: Glyphosate is the most widely used herbicide, and it poses numerous health risks to the environment and living organisms. This study aimed at assessing the protective role of Adansonia digitata (A. digitata) on glyphosate-induced hepatorenal toxicity in a Wistar rat model. Methods: Twenty-five rats were randomly divided into five groups of five animals each. The first group did not...

Greenhouse studies were conducted to determine the effect of 1-aminomethanamide dihydrogen tetraoxosulfate (AMADS) as a spray adjuvant on the efficacy of three different glyphosate formulations, the isopropylamine salt (glyphosate-IPA), potassium salt (glyphosate-K), and the acid of glyphosate dissolved in AMADS (glyphosate-A). All formulations were tested at multiple rates with and without AMA...

BACKGROUND Heterosis is a phenomenon that first-generation offspring perform better than their parents. Conventional breeding methods have their shortcomings. It would be optimal to construct inducible male sterile plants. RESULTS We developed a novel system for creating male sterile transgenic plants by downregulating the specific expression of the glyphosate tolerance CP4 EPSPS gene in male...

Glyphosate is a broad-spectrum herbicide used for the control of weeds in glyphosate-resistant crops. Glyphosate inhibits 5-enolpyruvyl shikimate 3-phosphate synthase, a key enzyme in the synthesis of aromatic amino acids in plants, fungi, and bacteria. Studies with glyphosate-resistant wheat have shown that glyphosate provided both preventive and curative activities against Puccinia striiformi...
