“…Therefore, it is necessary to carry out a study of the biological characteristics of the pathogen to investigate the suitable conditions for its occurrence and prevalence. Synthetic fungicides, such as metconazole [18] and carbendazim [19], are commonly used to control F. graminearum infection. However, biological control is becoming an important strategy in controlling F. graminearum to ensure food safety [20].…”

Kiwifruit (Actinidia chinensis) is an important commercial crop in China, and the occurrence of diseases may cause significant economic loss in its production. In the present study, a new pathogen that causes brown leaf spot disease on kiwifruit was reported. The fungus was isolated from an infected sample and identified as Fusarium graminearum based on morphological and molecular evaluation. Koch’s postulates were confirmed when the pathogen was re-isolated from plants with artificially induced symptoms and identified as F. graminearum. Based on the biological characteristics of the pathogen, it was determined that: its optimal growth temperature was 25 °C; optimal pH was 7; most suitable carbon source was soluble starch; most suitable nitrogen source was yeast powder; and best photoperiod was 12 h light/12 h dark. Further investigations were conducted by determining 50% effective concentrations (EC50) of several active ingredients of biological fungicides against F. graminearum. The results showed that among the studied fungicides, tetramycin and honokiol had the highest antifungal activity against this pathogen. Our findings provide a scientific basis for the prevention and treatment of brown leaf spot disease on kiwifruit.

“…The conditions in the field were suitable for FHB development (25–30 °C and 85% relative humidity), and no natural FHB developed in this field. FHB severity was rated 20 days after inoculation using the following scale: 0, no visible symptoms; 1, 1–3%; 2, 4–10%; 3, 11–25%; 4, 26–50%; 5, 51–75%; 6, > 75% of the spikelets showing FHB symptoms (Yu et al ., ). The disease index was [ n (1) × 1 + n (2) × 2 + n (3) × 3 + n (4) × 4 + n (5) × 5 + n (6) × 6]/(number of spikelets × 6) × 100, where n indicates the number of infected plants rated as 1, 2, 3, 4, 5 or 6.…”

Many endophytic fungi have been found to synthesize bioactive compounds to defend host plants against pathogenic organisms. Here we performed anti-fungal bioassay of 80 endophytic fungi isolated from Ginkgo biloba. Fifteen endophytes were active against at least one of the selected fungi, Fusarium graminearum, Sclerotinia sclerotiorum and Phytophthora capsici, using the agar diffusion method. The most bioactive strain CDW7 was identified as Chaetomium globosum by microscopic examination and ITS rRNA gene sequence data. Culture broth of CDW7 diluted 3-fold completely inhibited the mycelial growth and conidia germination of F. graminearum in vitro. Therefore, Fusarium head blight, a common disease in wheat and barley associated with Fusarium spp., was used to test the anti-phytopathogenic activity in vivo. The fermentation broth of CDW7 resulted in a protective efficacy of 54.9% and curative efficacy of 48.8%. Followed by a bioassay-guided approach, 1,2-benzenedicarboxaldehyde-3,4,5-trihydroxy-6-methyl (flavipin) was isolated and demonstrated to significantly inhibit the growth of several plant-pathogenic fungi, especially F. graminearum with an EC(50) value of 0.73 μg mL(-1) comparable to the commonly used fungicide carbendazim, indicating that it could be used as a fungicide or as a lead compound of new fungicides.

“…Additionally, benzimidazole fungicides (BMC), such as carbendazim, have been used in FHB management (Yu et al . ). Currently, wheat varieties with good levels of resistance are not available and the efficacy of triazole and triazolinthione fungicides is quite variable and rarely exceeds 65% (Paul et al .…”

“…The most commonly used fungicides to combat FHB belong to the demethylation inhibitors (DMI) group, and are formulated either as a solo activity ingredient (AI) or as a mixture of two AI such as two triazoles (tebuconazole and metconazole) and triazolinthione (prothioconazole) (Paul et al 2008). Additionally, benzimidazole fungicides (BMC), such as carbendazim, have been used in FHB management (Yu et al 2011). Currently, wheat varieties with good levels of resistance are not available and the efficacy of triazole and triazolinthione fungicides is quite variable and rarely exceeds 65% (Paul et al 2008).…”
