The efficiency of thiophanate-methyl was compared with that of S.P.F. (a Japanese formulation), benomyl, and thiabendazole when used as post-harvest treatments for the control of crown rot of banana hands artificially inoculated with Gloeosporium musarum. The fungicide treatments all provided some control but differed in the concentration required for equivalent effectiveness. Benomyl was the most effective with thiophanate-methyl being less efficient than either benomyl or thiabendazole, but superior to S.P.F.

Fusarium species produce toxic mycotoxins that are known to exert adverse health effects in humans and animals. No attempts have been made to establish mycotoxin-producing capabilities of isolates of Fusarium species from bananas exhibiting symptoms of crown rot. Crown rot is one of the most serious post harvest problems in banana and the disease is caused by different fungal species, principally Fusarium species. Banana, which is of great economic significance in growing countries (i.e. Costa Rica, Cameroon, Ecuador) is seriously affected by crown rot and is a major cause of fruit loss

Postharvest Loss

For reducing the post-harvest loss and extension of shelf-life of banana, it is treated with fungicide or combination of fungicide and hot-water treatment. A study was conducted for developing a method to control post-harvest diseases and extension of shelf-life of banana through non-chemical method of hot water treatment. The best treatment combination was found at 53 °C for 9 minutes. Shelf-lives of BARI Kola 1 and Sabri Kola treated with hot water increased by 26 and 27.5%, respectively against untreated fruits. Post-harvest loss (decay and crown rot) of these varieties was reduced, respectively by 95% and 70% against untreated fruits. Firmness of treated fruits for both varieties was found higher than that of untreated fruits during ripening. Total soluble solid, total sugar, acidity and ?-carotene of treated fruits of these varieties increased over untreated fruits. The pH and vitamin C of treated bananas decreased over untreated fruits during ripening.

The ability of fungicides to control Colletotrichum crown rot of strawberry caused by C. gloeosporioides was examined over three seasons. A single application of each fungicide was made 2 days before inoculation (2 DBI) or 1 day after inoculation (1 DAI) with conidial suspensions of C. gloeosporioides. The proportion of plants collapsed on one date at the end of each season was evaluated. In a combined analysis, there was a significant fungicide treatment-season interaction (P = 0.004). Percent mortality was 64% over 3 years in control plots that were inoculated with C. gloeosporioides but not treated with fungicide. Captan applied 2 DBI consistently reduced plant mortality (mean mortality = 17%). However, it was not as effective when applied 1 DAI (mean mortality = 46%). Azoxystrobin, pyraclostrobin, and thiophanate-methyl all reduced plant mortality relative to the control if applied 2 DBI (mean mortality = 46% for azoxystrobin, 37% for pyraclostrobin, and 41% for thiophanate-methyl) or 1 DAI (mean mortality = 29% for azoxystrobin, 27% for pyraclostrobin, and 32% for thiophanate-methyl). Results indicated that these fungicides were more effective when applied 1 DAI; however, lower plant mortality was not always observed with postinoculation applications. Cyprodinil + fludioxonil reduced mortality relative to the control, but there was no consistent evidence that it was more effective when applied at 2 DBI (mean mortality = 39%) than when applied 1 DAI (mean mortality = 40%). Similarly, mortality in plots treated with thiram 2 DBI (mean mortality = 30%) or 1 DAI (mean mortality = 32%) was not different. Potassium phosphite did not affect mortality, regardless of the timing of application (2 DBI mean mortality = 61%, 1 DAI mean mortality = 67%). The results indicated that an effective strategy for controlling Colletotrichum crown rot caused by C. gloeosporioides should be based on weekly applications of captan throughout the growing season. Azoxystrobin, pyraclostrobin, or thiophanate-methyl applications should be applied when weather conditions are highly favorable for disease development and the activity of contact fungicides such as captan or thiram might be compromised.

Screening Trials

Five chemicals were used in screening trials for the control of black end and anthracnose of bananas, both caused by Colletotrichum musae. Of the fungicides tested, Benlate (R)-[Methyl (l-butylcarbamoy1)- 2-benzimidazolecarbamate] was the most effective. Thiabendazole and 2-amino butane also gave significant control. In a larger scale trial varying concentrations of Benlate were examined using clusters of fruit in commercial fibreboard carton packs. At 100 p.p.m. and above a high degree of control of crown rot and anthracnose was achieved, both diseases being virtually eliminated at 400 p.p.m.

A study was made to compare the relative effectiveness of thiabendazole, benomyl, thiophanatemethyl and the methyl ester of benzimidazol-2-ylcarbamic acid, when used as post-harvest fungicides for the control of Penicillium digitatum in Washington Navel oranges. Twenty four hours after artificial wound inoculation the fruit was dipped for 30 seconds in suspensions of the materials, stored for seven days at 23�C and assessed for mould wastage. Relative to benomyl, thiabendazole was 0.27 times as effective (95 per cent fiducial limits 0.20 and 0.36); thiophanate-methyl 0.08 time (limits 0.06 and 0.11) and the ester 1.05 times as effective (limits 0.77 and 1.44).

Rot Disease

Introduction: The banana is the world’s most popular fruit crop. A complex of fungal pathogen is responsible for crown rot diseases of banana. Aims: The present study was designed to detect and characterize the crown rot disease of post-harvest banana (Musa paradisiaca) and also develop an alternative quality improvement approach to improve banana shelf-life during storage period. Study Design: A simplest general factorial experiment that was designed to control crown rot disease of banana using different biological factors, including plant extract, antagonistic agents and commercial fungicide. Place and Duration of Study: Disease infected bananas were collected from Rajshahi city, Rajshahi, Bangladesh in 2017 and the experiment had been conducted from April 2017 to April 2018. Methodology: Different morphological, biochemical and molecular techniques were used to characterize and detect the liable fungi. Responsible fungi were subjected to antifungal activity screening test and in vitro antagonism test. Effect of carbendazim and kanamycin B against the mycelial growth of the isolates was determined by disc diffusion method. Quality parameters including disease incidence and severity, pH, TSS, TTA and AA of the treated banana were also analyzed after application of treatments in the packing stage through standard estimation techniques. Results: Two fungi, isolated from the infected portion were further identified as C. musae and L. theobromae. D. metel and A. sativum extract was better in inhibiting mycelial growth of all the test pathogen in culture. B. cereus and T. harzianum moved and attached to fungal isolates, affecting mycelial growth and A. sativum extract significantly affecting conidial germination on artificial medium. Satisfactory mycelia inhibitory effect was recorded from kanamycin B. Quality analysis after storage of banana showed minor measurable differences among treatments. Conclusion: Post-harvest application of A. sativum extract (Conc. 25% w/v) improve the overall quality of harvested banana fruits and reduced the disease incidence and severity of crown rot to a level significantly lower than in fungicide treated or control fruits.
