Application of a Sex Pheromone, Pheromone Analogs, and Verticillium lecanii for Management of Heterodera glycines.
A mutant strain of the fungus Verticillium lecanii and selected bioregulators of Heterodera glycines were evaluated for their potential to reduce population densities of the nematode on soybean under greenhouse conditions. The bioregulators tested were the H. glycines sex pheromone vanillic acid and the pheromone analogs syringic acid, isovanillic acid, ferulic acid, 4-hydroxy-3-methoxybenzonit...

متن کاملCharacterization of Spanish strains of Verticillium lecanii.
We have characterized biologically and physiologically eight Verticillium lecanii strains from several origins including insect pests. Of all the temperatures tested, 25 degrees C was the best for growth and at 40 degrees C none of the strains could grow. At 4 and 7 degrees C, growth was reduced in comparison to warmer temperatures. The strains had better development at pH close to 7 (F = 27.64...
متن کاملEffects of a Mutant Strain and a Wild Type Strain of Verticillium lecanii on Heterodera glycines Populations in the Greenhouse.
A wild type strain ofVerticillium lecanii and a mutant strain with increased tolerance to the fungicide benomyl were evaluated in greenhouse experiments for effects on Heterodera glycines populations. Nematodes were applied at 300 eggs and juveniles per 4,550-cm(3) pot (two soybean plants in 4,990 g loamy sand per pot) and at both 300 and 10,000 eggs and juveniles per 1,720-cm(3) pot (one soybe...
متن کاملPathogenicity of Fungi to Eggs of Heterodera glycines.
Twenty-one isolates of 18 fungal species were tested on water agar for their pathogenicity to eggs of Heterodera glycines. An egg-parasitic index (EPI) for each of these fungi was recorded on a scale from 0 to 10, and hatch of nematode eggs was determined after exposure to the fungi on water agar for 3 weeks at 24 C. The EPI for Verticillium chlamydosporium was 7.6, and the fungus reduced hatch...
