Growth of Isolates of Paecilomyces lilacinus and Their Efficacy in Biocontrol of Meloidogyne incognita on Tomato.
The potential of 13 Paecilomyces lilacinus isolates from various geographic regions as biocontrol agents against Meloidogyne incognita, the effects of temperature on their growth, and the characterization of the impact of soil temperature on their efficacy for controlling this nematode were investigated. Maximum fungal growth, as determined by dry weight of the mycelium, occurred from 24 to 30 ...
متن کاملSurvival of Paecilomyces lilacinus in Selected Carriers and Related Effects on Meloidogyne incognita on Tomato.
Laboratory and microplot experiments were conducted to determine the influence of carrier and storage of Paecilomyces lilacinus on its survival and related protection of tomato against Meloidogyne incognita. Spores of P. lilacinus were prepared in five formulations: alginate pellets (pellets), diatomaceous earth granules (granules), wheat grain, soil, and soil plus chitin. Fungal viability was ...
متن کاملHistology of the Interactions of Paecilomyces lilacinus with Meloidogyne incognita on Tomato.
Excised tomato roots were examined histologically for interactions of the fungus Paecilomyces lilacinus and Meloidogyne incognita race 1. Root galling and giant-cell formation were absent in tomato roots inoculated with nematode eggs infected with P. lilacinus. Few to no galls and no giant-cell formation were found in roots dipped in a spore suspension of P. lilacinus and inoculated with M. inc...
متن کاملImpact of Paecilomyces lilacinus Inoculum Level and Application Time on Control of Meloidogyne incognita on Tomato.
Microplot experiments were conducted to evaluate the effects of inoculum level and time of application of Paecilomyces lilacinus on the protection of tomato against MeIoidogyne incognita. The best protection against M. incognita was attained with 10 and 20 g of fungus-infested wheat kernels per microplot which resulted in a threefold and fourfold increase in tomato yield, respectively, compared...
متن کاملMeloidogyne incognita Survival in Soil Infested with Paecilomyces lilacinus and Verticillium chlamydosporium.
Meloidogyne incognita-infected tomato seedlings were transplanted into sterilized soil or unsterilized soil collected from 20 California tomato fields to measure suppression caused by Paecilomyces lilacinus, Verticillium chlamydosporium, and other naturally occurring antagonists. Unsterilized soils Q, A, and H contained 35, 39, and 55% fewer M. incognita second-stage juveniles (J2) than did ste...
