Amelioration of root-knot disease of lady's finger plants by potentized Cina and Santonin

Abstract

Lady's finger plants (Hibiscus esculentus), grown in pots, were inoculated with the second-stage larvae (76+/-6) of root-knot nematodes Meloidogyne incognita, starting 7 days later they were treated with Cina 30c, Santonin 30c or Ethanol 30c by foliar spray for 10 consecutive days. The drugs in 90% ethanol were diluted with distilled water 1:1000 before application on plants. Thirty days after the last treatment the plants were uprooted. Cina 30c and Santonin 30c reduced nematode infestation of plants significantly in terms of root-gall number, root-protein content and nematode population in roots. Santonin 30c reduced root water content. Santonin 30c may have influenced the water channel proteins of root tissues thereby altering the water contents of roots. The reduced water content in roots might have adversely affected the root-knot nematodes and thus reduced nematode infestation. Ethanol 30c also has some effect on treated plants.

Influence of High Dilutions of <i>Cina</i> for the Control of <i>Meloidogyne incognita</i> in Tomato Plants

“…So it is possible that ethanol has served as an attractiveness to infestation by nematodes and consequently, there was a higher rate of galls on roots. Different results were observed when ethanol potentized at 30 CH was applied on okra plants, which was verified a significant reduction in the number of root galls and nematode population when treated with Cina 30 CH and Santonin 30 CH, when compared to treatment with ethanol 30 CH and inoculated and non-treated plants, which were statistically equal [12]. The authors emphasize that it must have occurred due to changes in the content of the root tissue of plants treated with Cina and Santonin, which disfavored infection by nematodes in the roots, so that they remained in the soil.…”

“…The treatments were administered in the soil three days before inoculation, on the day of inoculation, and 3, 10, and 17 days after inoculation. They were applied to the soil at a concentration of 0.1%, based on other works (Damin et al, 2014;Sukul et al, 2006) Daily measurements of the lesions caused by S. sclerotiorum were taken using a caliper as soon as the first symptoms appeared at the base of the plants, and ceased when the control plants were To analyze the data, an analysis of variance (ANOVA) was performed and, when relevant, regression analysis and the test of averages at a 5% probability of error were conducted using the statistical program GENES (Cruz, 2006).…”
