NewsDrone-based tech deployed to detect subtle signs of rice blast disease
Scientists have developed a novel vegetation index—the Rice Blast Index (RBI)—using drone-based hyperspectral remote sensing technology, to rapidly and non-invasively detect subtle signs of rice blast disease and achieve precise field management.

NewsNanoparticle smart spray helps crops block infection before it starts
As climate change fuels the spread of plant diseases worldwide, a new nanoparticle smart spray could help crops defend themselves by blocking harmful bacteria from entering through tiny pores in their leaves.

NewsCutting off parasite’s energy supply could help fight malaria
Once inside the body of an infected person, the malaria parasite relies on a process called glycolysis to produce energy and stay alive. Blocking the enzymes involved in this process could cut off the parasite’s primary energy source and kill it.

NewsChiral phytovirucide targets viral Nia protein to inhibit proliferation
A new study focuses on the search for small molecules to target the Nia protein of Potato virus Y (PVY), one of the most economically destructive viruses affecting Solanaceous crops such as potatoes, peppers, and tomatoes.

NewsLeafcutter ants recognize and fight pathogen with social immunity
Various characteristics of social immune memory were observed in colonies of Atta sexdens (lemon leafcutter ants) exposed to different pathogenic fungi. Such information is useful for future development of appropriate pest control.
-
NewsResearchers demonstrate new technique for boosting plant growth with bacteria
A single combined delivery system incorporating multiple active ingredients, including plant growth-promoting bacteria and agrochemicals, is developed to ensure beneficial bacterial survival and improve plant growths.

NewsNot the usual suspects: Novel genetic basis of pest resistance to biotech crops
A study reveals a novel genetic basis of resistance to transgenic crops in the corn earworm. To gain protection from this pest, crop plants had been genetically engineered to produce proteins from the common bacterium Bacillus thuringiensis, or Bt.

NewsSymbiotic bacterium affects reproduction of biological control insect
Researchers have revealed that the symbiotic bacterium Rickettsia induces strong cytoplasmic incompatibility (CI) in the predatory mirid bug, Nesidiocoris tenuis, which preys on agricultural pests such as whiteflies and thrips.

NewsTicks’ secret allies: Bacteria’s hidden hand in tick survival
A new study of the relationship between the brown dog tick, Rhipicephalus sanguineus, and its Coxiella-like symbiotic bacteria reveals the bacteria help the ticks by providing essential B vitamins and possibly other nutrients like L-proline.

NewsField deployment of Wolbachia-infected mosquitoes using uncrewed aerial vehicle
The World Mosquito Program has developed a technique to control dengue transmission by releasing Wolbachia-infected Aedes aegypti mosquitoes.

NewsCopper oxide nanoparticles to counter pathogens are synthesized from mango
Researchers have synthesized green copper oxide nanoparticles from Mangifera indica leaf extract. They showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on persimmon fruit pathogens.

NewsNovel Plasmopara viticola resistance locus discovered in ‘moldova’ grapes
Researchers have identified a Plasmopara viticola-resistant locus, Rpv34, in table grapes through analysis of a high-density genetic map with 826 SNPs derived from F1 progenies of ‘Moldova’ (resistant) and ‘Shine Muscat’ (susceptible parent).

NewsRoot microbiota fight back against leaf-mining flies
A pioneering study reveals how cowpea plants respond to leaf-mining fly attacks by altering their root-associated microbiota. Leafminer infestation changes the rhizosphere microbiome, enriching beneficial nitrogen-fixing bacteria.
-
NewsScientists discover genetic defense against Huanglongbing disease
A recent study has pinpointed two key enzymes in Citrus sinensis that play a crucial role in the plant’s defense mechanism against the Asian citrus psyllid (ACP), a vector for the lethal huanglongbing (HLB) disease.
