High resistance risk of Phytophthora colocasiae to azoxystrobin in southeastern of China.

Quinone outside inhibitor (QoI) has been applied to manage taro leaf blight caused by Phytophthora colocasiae in southeastern of China for many years. The risk of P. colocasiae to QoI and the potential resistant mechanism remain unknown.

Resistance risk and resistance-related point mutations in cytochrome b of florylpicoxamid in Colletotrichum scovillei.

Anthracnose caused by Colletotrichum scovillei is one of the most destructive diseases of chili worldwide. Florylpicoxamid is a new quinone inside inhibitor (QiI) fungicide, which shows intensively inhibitory activity against C. scovillei.

Analysis of the Difenoconazole-Resistance Risk and Its Molecular Basis in from Soybean.

Anthracnose disease, caused by , is a destructive fungal disease in soybean worldwide, and some demethylation inhibitor fungicides are used to manage it. In this study, the sensitivity of to difenoconazole was determined, and the risk for resistance development of to difenoconazole was also assessed. The results showed that the mean EC value was 0.

Three Species, Including a New Species, Cause Wet Bubble Disease of in China.

White button mushroom, (Lange) Imbach, is the most extensively cultivated and edible mushroom worldwide. The production of is commonly affected by wet bubble disease (WBD), imposing a significant economic burden in China. Although studies have shown that this disease is caused by fungi of the genus, the pathogen has not been fully characterized.

Analysis of the prochloraz-Mn resistance risk and its molecular basis in Mycogone rosea from Agaricus bisporus.

Background: Wet bubble disease (WBD), caused by Mycogone rosea, is one of the most serious diseases of white button mushroom (Agaricus bisporus) in China. Prochloraz-Mn is the main fungicide used in the management of WBD. To provide essential references for early warning of prochloraz-Mn resistance and management of WBD, this study was performed to assess the resistance risk to prochloraz-Mn in M.

[Biological effects of root exudates from resistant and susceptible banana varieties on f. sp. and ].

Root exudates of banana resistant variety ('Nantianhuang') and susceptible variety ('Guijiao No. 6') to Fusarium wilt were collected by bathing root system to examine the biological effects of root exudates from banana varieties on f. sp.

Characterization of Natural Isolates of Associated with Mating Types, Genetic Diversity, and Pathogenicity in Fujian Province, China.

Due to the natural destructiveness and persistence of the southern corn leaf blight (SCLB) fungus (Nisikado et Miyake) Shoem, the characterization of field isolates is essential to guide the rational distribution of resistant materials in corn-growing regions. In the present study, 102 field isolates collected from seven locations covering the entire region of Fujian Province, China, were assessed for mating type distribution, genetic diversity, and pathogenicity toward local sweet corn cultivars. Mating type detection via polymerase chain reaction indicated that 36.

Evaluating the Sensitivities and Efficacies of Fungicides with Different Modes of Action Against .

Asparagus stem blight caused by is a major hindrance to asparagus production worldwide. Currently, fungicides are used to manage the disease in commercial production, but resistance to common fungicides has emerged in the wild population. In the present study, 132 isolates of collected from different provinces in China were tested for sensitivities to pyraclostrobin, tebuconazole, and fluazinam.
