Effects of fenamiphos and biocontrol agents on cotton growing in nematode-infested soil
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 68 (1), 12-14
Abstract: Efficacy of a chemical nematicide, fenamiphos and three microorganisms in controlling Rotylenchulus reniformis and Tylenchorhynchus latus on cotton planted in field plots was investigated. Monthly records of the nematode population levels showed that fenamiphos had the highest (p < 0.05) levels of their control which resulted in the top cotton yield. Plots receiving the bacterium Bacillus sp. had various degrees of nematode control though their cotton yield was comparable (P < 0.05) to the fenamiphos-treated plots. Plots inoculated with a fungus Chaetomium spirale recorded the least effect for controlling the two nematode species and their cotton yield was not significantly different from the untreated plots. Plots treated with an actinomycete, Streptomyces sp., had an intermediate effect on both nematode population densities and cotton yield. At harvest, T. latus population densities were equally suppresed (P < 0.05) in all treatments which should be reflected on the subsequent crop.
