Native Bacteria Are Effective Biocontrol Agents at a Wide Range of Temperatures of Neofusicoccum parvum, Associated with Botryosphaeria Dieback on Grapevine

mycolabadmin

Researchers from Chile identified native bacteria (specifically Pseudomonas strains) that effectively prevent a destructive fungal disease affecting grapevines. These bacteria can work across a wide range of temperatures and significantly reduce fungal growth both in laboratory tests and in actual vineyard conditions. This discovery offers an environmentally friendly alternative to chemical fungicides for protecting grapevines, particularly important as younger vines appear more vulnerable to infection.

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

Growers struggle with fungal diseases that infect grapevine nurseries, reducing the quality of planting material. Researchers tested electrolyzed water—a solution made from salt and water using electricity—as a sustainable treatment for infected grapevine cuttings. Laboratory tests showed the treatment effectively killed fungal spores and reduced fungal growth. Field trials at a commercial nursery confirmed that treating cuttings with electrolyzed water reduced certain grapevine diseases without harming plant growth.

Scientists discovered that native bacteria from Chile, particularly Pseudomonas strains, can effectively control a serious fungus that damages grapevines. These bacteria work across a range of temperatures and successfully reduced fungal growth both in laboratory tests and in actual vineyards. This discovery offers a natural, environmentally-friendly alternative to chemical fungicides for protecting grape crops.

Argonaute1-Dependent LtmilR2 Negatively Regulated Infection of Lasiodiplodia theobromae by Targeting a Guanine Nucleotide Exchange Factor in RAS Signalling

Scientists discovered a tiny regulatory RNA molecule called LtmilR2 in a fungus that causes grape disease. This molecule naturally suppresses the fungus’s ability to cause infection by shutting down a gene called LtRASGEF. When researchers delivered LtmilR2 using specially designed nanoparticles, it successfully stopped the fungus from growing. This discovery could lead to a new type of biological fungicide for protecting grapes and vineyards.
