Biofungicides: Up to 65% Less CO₂ Compared to Chemical Solutions, Says Bureau Veritas

A comparative assessment shows that biological solutions are gaining strategic relevance, offering agronomic performance comparable to chemical products while enhancing soil health. Bureau Veritas's study reveals that biological fungicides, such as Biotrop's Bombardeiro, emit up to 65% less CO₂ than conventional chemical fungicides.

New Peer Communities: Towards Equitable Scientific Publishing

RNA Biopesticides: Nanoparticles Enhance Cotton Bollworm Control Efficiency

The use of chitosan nanoparticles to encapsulate double-stranded RNA (dsRNA) has shown increased efficacy against the cotton pest Helicoverpa armigera, while ensuring safety for pollinators. Results indicate a significant increase in larval mortality, even at reduced concentrations, with no observed toxicity to bees.

Effectiveness of Brachiaria Mavuno in Nematode Management Confirmed by Study

A study conducted by Araucária Soluções Agronômicas demonstrates that Brachiaria Mavuno, developed by Wolf Seeds, is an effective alternative for controlling nematode populations while improving soil structure. With a 65.8% reduction in nematodes compared to a soybean control, Mavuno stands out for its ability to maintain a high root mass, essential for soil health and the productivity of subsequent crops.

Plant Diseases: A Global Mapping of Bacterial Pathogens

An international study led by Professor Brajesh Singh (University of Western Australia) has mapped the hotspots of bacterial plant pathogens by analyzing 1,602 soil metagenomes from 59 countries. Researchers identified 32 dominant pathogens, particularly prevalent in warm ecosystems and agricultural soils. The study also shows that microbial diversity and soil organic carbon can limit their presence, paving the way for microbiome-based disease management strategies.

Agricultural Yields: Are Advances in Variety Selection Overestimated?

A study by researchers from the University of Nebraska published in Nature Communications suggests that yield gains attributed to variety selection may be largely overestimated. By analyzing 849 wheat varieties across several countries, the researchers demonstrate that a significant portion of the observed progress is actually due to maintenance selection aimed at sustaining performance against diseases and climate, rather than increasing yield potential.

Traditional Philippine Rice Reveals Key Genetic Traits for Climate Adaptation

A sequencing program of 1,001 traditional rice varieties, led by the Philippine Rice Research Institute and the University of the Philippines Los Baños, highlights early maturity traits and flood tolerance. These genetic resources could support the selection of more resilient and nutritious varieties in the face of climate challenges.

Soil Microbes: Unexpected Allies of Soybeans Against Nematodes

Researchers from the North Central Agricultural Research Laboratory of the USDA demonstrate that certain resistant soybean varieties recruit soil microorganisms capable of limiting the soybean cyst nematode (SCN), one of the most destructive pests of the crop. These microbial communities can then be transferred to other soils to protect sensitive varieties, paving the way for new protection strategies based on microbiome management.

AI-Designed Toxins Could Revolutionize Biopesticides

A study shows that peptide toxins targeting insect sodium channels can serve as a basis for new biopesticides. Researchers have resolved the structure of the NavPaS channel bound to two insect-selective toxins, Av3 and LqhαIT, using cryo-EM. With AI-assisted protein design tools, the insecticidal efficacy of LqhαIT has been doubled, paving the way for more targeted and potentially safer pest control agents.

A New Compact Gene Editor to Enhance Plant Breeding

A study published in Nature Plants by researchers from the University of California, Davis, and the Innovative Genomics Institute (UC Berkeley) highlights a gene editor that is more compact than CRISPR/Cas9, capable of making effective genetic modifications in tobacco. Based on an enzyme derived from 'jumping genes', this tool could accelerate plant breeding by enabling precise modifications without the insertion of foreign DNA.
