Rhizoctonia solani causes okra (Abelmoschus esculentus) seedling damping-off in South China with biological characterization and fungicide sensitivity profiling

mycolabadmin

Researchers identified Rhizoctonia solani as the fungus causing a serious disease in okra seedlings in southern China that was destroying about 35% of crops. The fungus dies when exposed to high temperatures (45-48°C) and grows best at about 28°C. Among seven tested antifungal treatments, a combination of trifloxystrobin and tebuconazole was most effective at controlling the pathogen, providing farmers with practical strategies for managing this crop disease.

Identifying Key Pathogens and Effective Control Agents for Astragalus membranaceus var. mongholicus Root Rot

mycolabadmin

Astragalus (a valuable traditional Chinese herb) often develops root rot disease caused by harmful fungi. Researchers identified the specific fungi causing this disease and tested various chemical fungicides and beneficial bacteria to control it. Carbendazim fungicide and a biocontrol bacterium called KRS006 proved most effective, suggesting a combination approach could protect this important medicinal plant from disease.

Isolation, Identification, and In Vitro Fungicide Screening of the Pathogen Associated with Pear Dry Blight

mycolabadmin

Pear dry blight is a serious fungal disease affecting pear orchards in China. Researchers identified the fungus Diaporthe fukushii as the cause and tested various fungicides to find the most effective treatments. The study found that thiophanate-methyl and difenoconazole mixed with propiconazole work best, while some other fungicides are less effective. The research provides farmers with evidence-based strategies to manage this devastating disease.

Biological characterization and in vitro fungicide screening of a new causal agent of walnut leaf spot in Guizhou Province, China

mycolabadmin

Researchers in China discovered that a fungus called Didymella segeticola is causing a serious leaf spot disease in walnut trees in Guizhou Province. They studied how this fungus grows under different conditions and tested 20 different fungicides to find the most effective treatments. Two fungicides—difenoconazole and tetramycin—were found to be particularly effective at stopping the fungus, offering practical solutions for protecting walnut crops.

The Impact of Sugar Beet Seed Pelletization on the Proliferation of Nematophagous Fungi

mycolabadmin

Sugar beet seeds are often coated with protective chemicals to improve planting. This study found that these chemical coatings significantly inhibit the growth of beneficial fungi that naturally attack plant-damaging nematodes. While these fungi can still be applied to fields separately as a biological pest control, they should not be added directly to the seed coating because the chemicals would kill them. Farmers could use a combination approach by applying the fungi to soil separately while using treated seeds.

Identifying Key Pathogens and Effective Control Agents for Astragalus membranaceus var. mongholicus Root Rot

mycolabadmin

Astragalus root, a valued traditional Chinese medicine, suffers from a serious fungal disease caused primarily by two Fusarium species. Researchers tested eight fungicides and nine beneficial bacteria to find the most effective treatments. The chemical fungicide carbendazim and a beneficial bacterium called KRS006 proved most effective, offering promise for developing better disease management strategies that combine both chemical and biological approaches.
