Pasteuria penetrans for Control of Meloidogyne incognita on XXXX and @entity9688 , and M. arenaria on Snapdragon.

@entity9688 @entity34731 @entity523 @entity2199
Meloidogyne incognita and Meloidogyne arenaria are important parasitic @entity2199 of vegetable and ornamental crops. Microplot and greenhouse experiments were conducted to test commercial formulations of the biocontrol agent Pasteuria penetrans for control of M. incognita on @entity523 and @entity9688 and M. arenaria on snapdragon. Three methods of application for P. penetrans were assessed including seed, transplant, and post-plant treatments. Efficacy in controlling galling and reproduction of the two root-knot @entity2199 species was evaluated. Seed treatment application was assessed only for M. incognita on @entity9688 . Pasteuria treatment rates of a granular transplant formulation ranged from 1.5 * 10(5) endospores/cm(3) to 3 * 10(5) endospores/cm(3) of transplant mix applied at seeding. Additional applications of 1.5 * 10(5) endospores/cm(3) of soil were applied as a liquid formulation to soil post-transplant for both greenhouse and microplot trials. In greenhouse @entity9688 trials, all Pasteuria treatments were equivalent to steamed soil for reducing M. incognita populations in roots and soil, and reducing @entity2199 reproduction and galling. In @entity9688 microplot trials there were no differences among treatments for M. incognita populations in roots or soil, eggs/g root, or root condition ratings. @entity2199 reproduction on @entity9688 was low with @entity34731 and with the seed treatment plus post-plant application of Pasteuria, which had the lowest @entity2199 reproduction. However, galling for all Pasteuria treatments was higher than galling with Telone II. Root-knot @entity2199 control with Pasteuria in greenhouse and microplot trials varied on @entity523 and snapdragon. Positive results were achieved for control of M. incognita with the seed treatment application on @entity9688 .
