Postharvest Disease Management of ‘Akizuki’ Pear in China: Identification of Fungal Pathogens and Control Efficacy of Chlorine Dioxide

mycolabadmin

Researchers identified four types of fungi that cause rot in ‘Akizuki’ pears during storage: Alternaria alternata, Diaporthe eres, and two types of Penicillium. They tested chlorine dioxide gas as a treatment and found it effectively stopped the fungi from growing without harming the fruit. This discovery offers a safer, more environmentally friendly alternative to traditional fungicide chemicals for keeping stored pears fresh longer.

An Efficient Microwave Synthesis of 3-Acyl-5-bromoindole Derivatives for Controlling Monilinia fructicola and Botrytis cinerea

Researchers created new chemical compounds based on indoles that can kill harmful fungi affecting fruit crops. These compounds were made using microwave energy, which made the synthesis faster and more efficient. Testing showed that some of these new compounds worked better at stopping fungal growth and spore germination than currently used commercial fungicides, making them promising candidates for protecting fruit crops from rot diseases.

Optimizing a modified cetyltrimethylammonium bromide protocol for fungal DNA extraction: Insights from multilocus gene amplification

mycolabadmin

Researchers developed an improved method for extracting fungal DNA that is faster, cheaper, and safer than current commercial kits. The new protocol works by using a special chemical solution and simple crushing tools instead of expensive equipment like liquid nitrogen or bead beaters. They tested it on 40 different fungal species found in dry fruits and successfully identified them all using genetic markers, showing the method could help diagnose fungal diseases in plants, animals, and humans.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four new species of endophytic fungi called Diaporthe living inside plant tissues without causing visible disease. Using genetic testing and microscopic examination, they identified D. caryae, D. phoenicicola, D. stewartii, and D. unshiuensis as previously unrecorded in Korea. These fungi can potentially produce compounds with medicinal properties or help manage plant diseases. This discovery helps scientists better understand the hidden fungal diversity in Korean ecosystems.

Polyphasic characterization and mating type allele distribution of Monilinia laxa in Iranian stone fruit orchards

Brown rot is a serious fungal disease affecting fruit trees like apricots, cherries, and plums. Researchers collected over 400 fungal isolates from Iranian fruit orchards and identified two main species causing the disease, with one species being far more common. By developing new genetic tests, scientists discovered both male and female forms of the fungi exist in equal proportions, suggesting the disease could evolve through sexual reproduction, which has important implications for managing the disease in orchards.

Antifungal Effect of Cinnamon Bark Extract on the Phytopathogenic Fungus Fusarium sporotrichioides

mycolabadmin

This study tested whether cinnamon bark extract could stop the growth of a harmful fungus called Fusarium sporotrichioides that damages crops and produces toxins. Researchers used a water-based cinnamon extract at different concentrations on fungal cultures and found that the highest concentration significantly reduced fungal growth and caused visible damage to fungal structures. The cinnamon extract contains natural compounds with antifungal properties that could potentially be used as an eco-friendly alternative to synthetic fungicides in agriculture.

Improvement of antioxidant capacity, aroma quality, and antifungal ability of cherry by phenyllactic acid treatment during low temperature storage

mycolabadmin

Researchers found that treating sweet cherries with phenyllactic acid (PLA), a natural organic acid, can significantly extend their shelf life while keeping them fresh and flavorful. A treatment with 8 mmol·L⁻¹ PLA concentration worked best, reducing decay, maintaining firmness and sweetness, and improving the fruit’s natural antioxidant properties during cold storage. This natural preservative approach offers a safe alternative to chemical fungicides while preserving the delicious taste and nutritional quality that consumers value in cherries.

Comprehensive analysis of the mechanisms conferring resistance to phenamacril in the Fusarium species

mycolabadmin

Fusarium fungi cause serious diseases in crops like wheat, corn, and fruits, causing huge losses in agriculture worldwide. Phenamacril is a new antifungal drug designed specifically to fight these fungi by blocking a protein they need to grow. However, the fungi are developing resistance to this drug through genetic mutations and other biological mechanisms, making it less effective over time. Understanding how this resistance develops helps scientists develop better strategies to maintain the drug’s effectiveness and protect our food supply.
