“…Depuis 1970, la dodine y a ete utilisee avec satisfaction, en alternance avec les dithiocarbainatcs, sclon une tcchniquc prcconisant dcs traitements a cadence fixe (hebdomadaircs) sans tenir compte des facteurs de l'environnement (Cesari r t al., 1976;Minghetti et ol., 1977). A partir des annecs 70, des Cchecs ont cte cnregistres dans ccs vcrgcrs, laissant supposcr la prescnce de souches resistantes du champignon pathogene, comme cela avait deja ete le cas aux Etats-Unis et au Canada (Szkolnik & Gilpatrick: 1969;Jones & Walker. 1976: Ross & Ncwbery, 1977McKay & MacNeill, 1979).…”

Des recherches réalisées au cours des trois dernières années sur l'éventuelle variation de la sensibilité de Venturia inaequalisà la dodine ont mis en évidence la résistance de certaines populations à ce fongicide, utilisé depuis très longtemps et de façon intensive dans les vergers d'Italie septentrionale. Les résultats ont été obtenus dans des vergers traités à la dodine depuis aumoins 10 ans. Les mêmes échantillons ont montré une variation de la sensibilitéà la dodine au cours des applications d'une seule saison.

“…Benzimidazole fungicides are used for the management of diseases caused by Botrytis , Monilinia , Colletotrichum , Sclerotinia , Podosphaera , and so on ( Bradley et al, 2006 ; Chen et al, 2014 ; Hwang et al, 2010 ; Sedláková and Lebeda, 2008 ). However, the use of the fungicide has resulted in point mutation that confers resistance of the pathogen to the fungicide ( Albertini et al, 1999 ; Jones and Walker, 1976 ; Ross and Newberry, 1985 ). Resistance to benzimidazole-based fungicide was reported in New Zealand in 1975 on apple scab disease caused by Venturia inaequalis and it was also reported in 1977 in Japan on Venturia nashicola on pear ( Hartill, 1986 ; Ishii and Yamaguch, 1977 ).…”

Colletotrichum species is known as the major causal pathogen of red pepper anthracnose in Korea and various groups of fungicides are registered for the management of the disease. However, the consistent use of fungicides has resulted in the development of resistance in many red pepper-growing areas of Korea. Effective management of the occurrence of fungicide resistance depends on constant monitoring and early detection. Thus, in this study, various methods such as agar dilution method (ADM), gene sequencing, allele-specific polymerase chain reaction (PCR), and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were applied for the detection of benzimidazole resistance among 24 isolates of Colletotrichum acutatum s. lat. and Colletotrichum gloeosporioides s. lat. The result of the ADM showed that C. gloeosporioides s. lat. was classified into sensitive and resistant isolates to benomyl while C. acutatum s. lat. was insensitive at ≥1 µg/ml of benomyl. The sequence analysis of the β-tubulin gene showed the presence of a single nucleotide mutation at the 198th amino acid position of five isolates (16CACY14, 16CAYY19, 15HN5, 15KJ1, and 16CAYY7) of C. gloeosporioides s. lat. Allele-specific PCR and PCR-RFLP were used to detect point mutation at 198th amino acid position and this was done within a day unlike ADM which usually takes more than one week and thus saving time and resources that are essential in the fungicide resistance management in the field. Therefore, the molecular techniques established in this study can warrant early detection of benzimidazole fungicide resistance for the adoption of management strategies that can prevent yield losses among farmers.
