The surfactants Triton X-100 and X-171 were found to facilitate the replica plating of Fusarium solani by markedly inhibiting the radial growth of this fast-growing fungus. In addition, specific types of morphological mutants were isolated which assisted the replica plating of F. solani.

Anti Fungal

The anti-fungal activity of schefflone, a mixture of dimmer, 3,5 dimethoxy carvacrol and annonaceous acetogenin, extracted from stem-bark and root of Uvaria scheffleri and Artabotrys bruchypetalus against Fusarium solani, Botryodiplodia theobromae, Asperillus niger and Aspergillus flavus was determined. An in-vitro bioassay showed that the minimum inhibitory effect of the compounds to the fungal pathogens occurred at 200 ppm in both radial growth and mycelia dry weight measurements. Acetogenin from A brachypetalus had a very strong anti-fungal effect on all the test fungi. The effects of the compounds were more pronounced on F solani than on the other. The bioassay methods also play a significant role in the sensitivity of the samples on the pathogens. .

Chitosan hydrolysate was obtained using nitric acid; the prevailing fraction had a molecular weight of 30 kDa and a deacetylation degree of 95%. The effect of chitosan hydrolysate when added to potato dextrose agar (PDA) in different concentrations (0.5, 1, 1.5, 2, 4, 6 and 8 mg/mL) was studied on the growth of the fungi Alternaria solani Sorauer, Fusarium solani (Mart.) Sacc. and Rhizoctonia solani J.G. Kühn. A. solani was the most sensitive to the addition of chitosan hydrolysate to PDA in radial growth experiments. On days 3 and 7 of incubation, the antifungal activity of the phytopathogen growth was 69%-92% and 69%-88%, respectively, in the concentration range of 0.5-2 mg/ml.

Guar gum (Galactomannan) is extracted from Guar (Cluster bean), which is extensively used in petroleum, food and pharmaceutical industry. Root rot of guaris caused by Fusarium solani EGY1 under Punjab, having sub-tropical climatic conditions. This study was undertaken to evaluate different culture media, grain substrates (sorghum, maize, cowpea, guar and pearl millet), temperatures (20, 25, 30, 35oC), pH levels (5.0, 6.0, 7.0, 8.0), light and darkness for the identification of optimum conditions for the growth and sporulation of the fungus. Czapek’s dox media was found to be best for growth (84.65 mm) and sporulation (1.8 x 104microconidia and 3.0 x 104 macro conidia) of fungus. For mass multiplication of the fungus, sorghum grains proved to be the best substrate. The fungus showed maximum radial growth at temperature of 25oC (84.36 mm) and pH of 6.0 (84.43 mm) whereas sporulation was highest at 30oC (2.0 x 104 microconidia and 3.2 x 104 macroconidia) and pH of 8.0 (1.8 x 104 microconidia and 3.1 x 104 macroconidia) respectively. Continuous light favoured radial growth (84.62 mm) whereas sporulation (1.8 x 104 microconidia and 3.1 x 104 macroconidia) was favoured by darkness.

Acalypha Wilkesiana

This large, fast-growing evergreen shrub provides a continuous splash of color in the landscape. The bronze red to muted red 4- to 8-inch-long, heart-shaped leaves are available in varying mottled combinations of green, purple, yellow, orange, pink, or white, depending upon cultivar (Figure 1). These colors make copperleaf difficult to blend into the landscape. Two or three shrubs are usually sufficient for specimen or accent plantings. Be careful not to over-plant with copperleaf. Their unusual color attracts attention and they could look gaudy. The dense, much-branched growth habit creates a full shape, but plants occasionally need shaping to maintain a neat appearance. The upright growth of copperleaf can reach 10 to 15 feet in height, making it well-suited to use as an accent in mixed shrubbery borders. Upright and side branches eventually droop and the plant can spread to about 8 feet wide. The unusual, red, fuzzy, catkin-like flowers hang pendulously from leaf axils and are 8 to 12 inches long. It has been used as a hedge or screen planted on 3- to 5-foot centers. This document is Fact Sheet FPS-6, one of a series of the Environmental Horticulture Department, Florida Cooperative Extension Service, Institute of Food and and Agricultural Sciences, University of Florida.
