EFFECT OF SOME FUNGICIDES AND ALTERNATIVE COMPOUNDS ON ROOT AND POD ROTS IN PEANUT
Plant Pathology Research Institute, Agricultural Research Center, Giza, Egypt
Abstract
Effect of three fungicides and three alternative compounds on the incidence of root and pod rots in peanut was evaluated and compared under greenhouse and field conditions. The fungicides were vitavax-thiram, rizolex-T and topsin-M70, while the alternative compounds were plant-guard (a formula of Trichodonna harzianum), rhizo-N (a formula of Bacillus subtilis) and the synthetic saponin. Experiments were carded out in artificially infested soil in the greenhouse, whereas the field was left for natural infection. The synthetic saponin was not used in pod rot experiments. All treatments reduced the percentage of root and pod rots in both the greenhouse and the field. Percent infection was less with fungicides than when the alternative compounds were used. Root rot was as low as 8.24% in greenhouse and 6.67% in field under fungiddal treatments compared to 14.94% and 11.33% with the alternative compounds, respectively Pod rot was 7.73 in greenhouse and 5.97 % in field in response to fungicides, while it was 12.17 and 12.50 % with the alternative compounds, respectively. Also, all treatments increased pod yield compared to the non-treated control. The fungicidal treatments gave a higher yield than that obtained in the alternative compound treatments.
