How resilience innovations in food supply chains are revolutionizing logistics, wholesale trade, and farm services in developing countries por Reardon, Thomas, Vos, Rob

“…Developing country food supply chains have been pummeled by a series (and often a confluence) of shocks over the past several decades, including the Russia-Ukraine war, COVID-19, climate shocks from hurricanes to floods to droughts, animal and plant diseases, an intensification of road banditry and local conflicts, and overlaying all these, deep transformation in markets themselves with new requirements for quality and food safety. …”

The effect of slash and burn agriculture on plant nutrientes in the Tertiary Region of Central Amazonia por Brinkmann, W.L.F, Nascimiento, J.C. do

“…The current availability of nutrients has been significantly reduced due to solid fixation It is concluded, based on the results obtained, that the nutrient return caused by burning is not capable of guaranteeing tropical agriculture in the long term. pH correction and the use of good fertilizers are necessary, as is the use of herbicides, insecticides, and fungicides to reduce root competition and plant diseases. It is advisable to establish favorable conditions for protection against the impact of atmospheric agents through the use of shading, observing the requirements of each crop.…”

Sensitive detection of Xanthomonas oryzae Pathovars oryzae and oryzicola by loop-mediated isothermal amplification por Lang, Jillian M., Langlois, Paul, Nguyen, Marian Hanna R., Triplett, Lindsay R., Purdie, Laura, Holton, Timothy A., Djikeng, Appolinaire, Vera Cruz, Casiana M., Verdier, Valérie, Leach, Jan E.

“…Loop-mediated isothermal amplification (LAMP) is a PCR-based tool that allows the rapid, highly specific amplification of target DNA sequences at a single temperature and is thus ideal for field-level diagnosis of plant diseases. We developed primers highly specific for two globally important rice pathogens, Xanthomonas oryzae pv. oryzae, the causal agent of bacterial blight (BB) disease, and X. oryzae pv. oryzicola, the causal agent of bacterial leaf streak disease (BLS), for use in reliable, sensitive LAMP assays. …”

Programmed cell death suppression in transformed plant tissue by tomato cDNAs identified from an Agrobacterium rhizogenes-based functional screen por Harvey, Jagger J.W., Lincoln, J.E., Gilchrist, D.G.

“…Anti-PCD genes recovered by this screen represent potential sources of resistance to PCD-dependent plant diseases, while the screen should be useful to identify genes capable of suppressing PCD triggered by other effectors, including those expressed by root pathogens during infection.…”

Restoring soil health from long-term intensive Robusta coffee cultivation in Vietnam: “A review” por Van, Long Nguyen, Quang, Duy Nguyen, Laetitia, Herrmann, Enez, Aydin, Brau, Lambert, Van, Chung Nguyen, Katz, Mathias, Lesueur, Didier

“…We found that the overuse of nitrogen-based chemical fertilizers to grow coffee is the primary driver of soil acidification, consequently increasing soilborne diseases and the severity of plant diseases. Additionally, the effects of soil amendments as a sustainable solution to reduce soil acidity, enhance soil health, and better control soilborne pathogens. …”

The effect of combining two biological control microbes on seed and root colonization por Wang, Jinhui

“…Clonostachys rosea strain IK726 and Pseudomonas chlororaphis strain MA342 are two promising biocontrol microbes which both has various biocontrol mechanisms to control many seed and soil-borne plant diseases. Because a potential additive effect may exist between these two biocontrol microbes, like an expanded antagonistic spectrum and enhanced persistence of biocontrol effect, we expected to get a more competitive biocontrol with a mixture of IK726 and MA342. …”
