Abstract:

The main objective of this article is to give an overview of both the right to a clean and healthy environment adopted in international and national agreements, and the effects that the release of genetically modified organisms (GMOs) into the environment (especially genetically modified maize) may cause to human, animal and plant health. This article is divided into three sections: The first section focuses on the right to a clean and healthy environment and its enjoyment as a third generation human right in Mexico and the European Union; the second section briefly examines the global status

Abstract Naphthalic anhydride is a seed-applied herbicide safener which reduces the toxicity of imazethapyr, an imidazolinone herbicide, to maize (Zea mays L.). Protection of maize from imazethapyr was dependent on the amount of naphthalic anhydride applied to the seed. Metabolism of imazethapyr by maize roots and shoots was increased by exposure of the roots to a solution containing naphthalic anhydride. Increased imazethapyr metabolism due to naphthalic anhydride treatment of roots was observed within 4 h following safener exposure. Nitrogen, carbon monoxide and tetcyclacis inhibited im

Green leaf volatiles (GLVs), which have mostly been described as providers of protection against insect herbivory and necrotrophic pathogen infections, were recently shown to provide significant fortification against cold stress damage. It was further demonstrated that cold-damaged maize seedlings released a significant amount of GLVs, in particular, Z-3-hexenal (Z-3-HAL). Here, we report that the in-cold treatment of maize seedlings with Z-3-HAL significantly improved cold stress resistance.

Maize is a global leader among grain crops in terms of planting area. Its uniqueness is related to a high potential yield and versatility. There are a great number of pest species that significantly damage maize plants reducing the yield by 30-50 % sometimes and drastically decreasing grain quality. One of the most dangerous pests in Russia and overseas is the corn borer.

Insect herbivores depend on their host plants to acquire macro- and micronutrients.

Maize plants use these same benzoxazinoids for protection against generalist herbivores and, as shown here, for iron uptake. We identify an iron transporter that allows th

SUMMARYIn 1981 and 1982, three crop protection regimes were compared with an unsprayed control for cowpea grown alone and in mixtures with maize, sorghum and cotton. Unsprayed cowpea in mixtures with maize had yields which suggested some pest escape in 1981 but not in 1982. When sprayed, only the maize–cowpea mixture showed much yield advantage over sole crops. For maize–cowpea in 1983, a very dry year, only the alternate row mixtures showed a yield advantage and three spray applications gave cowpea yields as good as those resulting from six applications.

Abstract:

Widespread use of genetically engineered maize targeting the corn rootworm complex ( Diabrotica species) has raised concerns about insect resistance. Twelve years of university field trial and farm survey data from 10 US Corn Belt states indicate that maize hybrids expressing toxins derived from the bacterium Bacillus thuringiensis (Bt maize) exhibited declining protection from rootworm feeding with increased planting while pest pressures simultaneously decreased. The analysis revealed a tendency to overplant Bt maize, leading to substantial economic losses; this was particularly striking in e

The study analyzed the records of maize ear damage for four maize fields in Southeast Hungary, Csongrád-Csanád County, in 2021. The performance of Sentinel-2 bands, PRISMA bands, and synthesized Sentinel-2 bands was compared using linear regression, partial least squares regression (PLSR), and two-band vegetation index (TBVI) methods.

Abstract:

Maize is a staple crop that plays a key role in global food security. It is a primary source of food for millions of people and provides essential raw materials for various industries, including animal feed and biofuel production. However, maize cultivation faces increasing challenges in the 21st century, in particular the negative impact of climate change. As our planet undergoes rapid climate change, the agricultural sector must adapt to ensure consistent and sustainable maize production. One of the critical challenges posed by climate change is the proliferation of pests that threaten maize

In contrast to other potentially toxic secondary metabolites, BXs have not been targets of counter selection during breeding and the effect of BXs on insects, microbes, and neighbouring plants has been recognised. A broad knowledge about the mode of action and metabolisation in target organisms including herbivorous insects, aphids, and plants has been gathered in the last decades.

In plants the chloroplast is a major site of free radical production and paclobutrazol protects plants by increasing antioxidant defense systems. Leaves from paclobutrazol-treated maize (Zea mays L. cv. Pioneer 3902 and Pride 5) had larger chloroplasts and grana stacks, and more stromal lamellae. Treated leaves had more epicuticular wax and were thicker and wider owing to enlarged vascular bundles, epidermal, mesophyll, and bundle sheath cells. Paclobutrazol increased survival rate following chilling (2°C for 8 h) and alleviated damage symptoms owing to chilling and exposure to paraquat (60 an
