Effects of rice-cultured Paecilomyces lilacinus on Rotylenchulus reniformis were studied in both greenhouse and field microplot tests with 'Rutgers' tomato. Numbers of R. reniformis were reduced (P </= 0.05) by P. lilacinus, with suppression in the initial greenhouse test ranging from 46 to 48% for two rice + P. lilacinus treatments; the rice-only treatment caused a nonsignificant reduction of ...

N-Viro Soil (NVS) is an alkaline-stabilised biosolid that has been shown to suppress Meloidogyne incognita. In separate microplot studies, NVS was applied either alone at different rates (0, 25, 50, 75, 100 dry t ha−1), or in combination with M. incognitaresistant and M. incognita-susceptible cultivars, to different M. incognita initial densities (0, 37 500, 75 000 eggs/microplot). NVS suppress...

Inoculation of wheat seeds with two strains of Pseudomonas fluorescens (III107 and II21) and two strains of Bacillus mycoides (JC192 and K184) isolated from winter wheat roots, as well as with one strain of P fluorescens (ID13) isolated from oat roots, reduced the negative influence of Fusarium culmorum on winter wheat in a 28 day pot experiment. The bacterial strains (especially III107 and chi...

Greenhouse and field microplot studies were conducted to compare soybean shoot and root growth responses to root penetration by Heterodera glycines (Hg) and Meloidogyne incognita (Mi) individually and in combination. Soybean cultivars Centennial (resistant to Hg and Mi), Braxton (resistant to Mi, susceptible to Hg), and Coker 237 (susceptible to Hg and Mi) were selected for study. In the greenh...

Population dynamics of Meloidogyne chitwoodi were studied for 2 years in a commercial potato field and microplots. Annual second-stage juvenile (J2) densities peaked at harvest in mid-fall, declined through the winter, and were lowest in early summer. In the field and in one microplot study, population increase displayed trimodal patterns during the 1984 and 1985 seasons. Overwintering nematode...

Inula viscosa is a perennial plant that is widely distributed in Mediterranean countries. Formulations of I. viscosa extracts were tested for their effectiveness in control of Meloidogyne javanica in laboratory, growth chamber, microplot, and field experiments. Oily pastes were obtained by extraction of dry leaves with a mixture of acetone and n-hexane or n-hexane alone, followed by evaporation...

A soybean cyst nematode sex pheromone (vanillic acid), chemical analogs of the pheromone, and the fungus Verticillium lecanii were applied in alginate prills (340 kg/ha) to microplots and small-scale field plots as potential management agents for Heterodera glycines on soybean. In 1991 microplot tests, treatment with V. lecanii, vanillic acid, syringic acid plus V. lecanii, or vanillic acid plu...

A microplot study was conducted on a medium black soil to screen improved sulphur (S) utilizers among blackgram genotypes. For this experiment, four different S sources including Gypsum, SSP, FeSO4, and ZnSO4, were applied at levels (S @ 0, 20, 30, 40 kg ha-1). With the application of high (40 ha-1), growthand yield parameters (plant height, root length number pods per plant) gram increased sig...

The microplot experiment was carried out on two soils (clay and sandy) with spring wheat fodder pea. In the experiment, effect of a granular product made basalt dust elemental sulphur content 1.5% tested. Fertilization in dose 30 kg/ha S pea 20 form basalt-sulphur granulate resulted significant increase methionine, cystine protein grain sandy soil. However, no these amino acids seeds observed. ...

Rotylenchulus reniformis resistant LONREN-1×FM966 breeding lines developed at Auburn University have demonstrated that the nematode resistance is accompanied by severe stunting, limited growth, and low yields. The objectives of this study were to evaluate the effects of applying nematicides to selected LONREN breeding lines on R. reniformis nematode populations, plant stunting, and yield. Four ...
