EVALUATION OF SEED TREATMENTS ON THE NODULE COMPETENCY OF SOYBEAN INOCULANTS
… from atmosphere for vegetative growth and seed production through the symbiosis with the soil bacterium Bradyrhizobium japonicum (B. japonicum). However, the native soil bradyrhizobia may be ineffective in nitrogen fixation and the greatest limiting factor in increasing symbiotic nitrogen …

Effect of fungicide seed treatments on Fusarium virguliforme and development of sudden death syndrome in soybean
… for disease development. This suggests fungicide seed treatments could be effective in limiting early infection possibly resulting in disease control. Field, greenhouse, and laboratory studies were conducted to evaluate eight fungicides in multiple seed treatment combinations for effects on Fv …

A Study of Neonicotinoid Seed Treatments in Bt Maize: Insect Resistance Management, Efficacy, and Environmental Fate
… States (US) is treated with a neonicotinoid seed treatment (NST), and transgenic (GMO) maize, Zea mays L. (Poaceae), that produces insecticidal toxins by way of genes derived from Bacillus thuringiensis (Bt), occupies more than 75% of maize acreage. Among a variety of secondary pests targeted …

Response of alfalfa to foliar applications of long-chain fatty acids or seed treatments with Chevron XE-1019
… when applied to 21 and 28 day-old plants. DPA treatments also had no effect (p=0.05) on the leakage of Ca²⁺, K⁺, Mg²⁺, and PO₄³⁻ from foliar leaf discs. Foliar treatments containing either 10 mM CaCl₂ + DPA or 10 mM CaC1₂ were effective in increasing shoot biomass in plants grown in solution …

Evaluation of Safening Effects to Herbicides Conferred via Insecticide Seed Treatments in Soybean (Glycine max) and Grain Sorghum (Sorghum bicolor)
… recent research has shown that, when applied as seed treatments prior to planting, some neonicotinoid insecticides can safen rice to drift from both glyphosate and imazethapyr. Since insecticide seed treatments are commonly used in many crop production systems throughout the Midsouth, exploring …

Soybean disease research on green stem disorder, effects of seed treatments on Sclerotinia stem rot, and resistance to Cercospora leaf blight
… maturity with normal, fully mature pods and seeds. Data on GSD incidence were collected for 1090 soybean cultivars from 2009 to 2012 at seven locations throughout Illinois. Data on six agronomic traits were also collected for every GSD observation, including height, lodging, moisture, …

Detection of Acidovorax citrulli, the Causal Agent of Bacterial Fruit Blotch Disease of Cucurbits, Prevention via Seed Treatments and Disease Resistance Genes
… on watermelon crops and $75M (worldwide) to the seed and transplant industries since 1996. Disease symptoms include water-soaked cotyledons, leaf necrosis, and internal fruit rot. Current commercial management strategies are very limited and include: seed production field sanitation, greenhouse …

Evaluation of Pythium root rot and damping off resistance in the ancestral lines of North American soybean cultivars and chemical control of the active ingredient ethaboxam in seed treatments
… Merrill) earlier in the growing season has made seedling diseases more prominent. A survey of biotic causes of yield loss between 2006 and 2009 rated seedling diseases second in only to soybean cyst nematode. Pythium ultimum var. ultimum is an oomycete that favors cool wet conditions in early …

Evaluation of Rhizoctonia solani - Heterodera glycines interactions on soybean
… were conducted to evaluate four fungicide seed treatments in multiple combinations to evaluate this interaction as well as early season control of the pathogens. Seed treatments were applied to soybean cultivars that were resistant and susceptible to SCN. Field studies were conducted at two …

Evaluation of Agents for the Suppression of Take-all of Wheat in Virginia in Greenhouse and Field Studies, and Characterization of Isolates of Gaeumannomyces graminis varieties
… in Virginia. 'Jackson' soft red winter wheat seeds were planted in a Kempsville loam containing millet seed infested with Ggt or sterile millet seed in the greenhouse. Root necrosis ratings, and root and shoot weight were determined as a measure of disease severity. In the field, plots were …

Influence of seed and foliar applications of growth regulators on turfgrasses
The effects of propiconazole and seaweed extract seed treatments on the germination of Kentucky bluegrass (<i>Poa pratensis L.</i>) under osmotic and temperature stresses were determined in the laboratory. As polyethylene glycol (PEG) 8000 concentrations was increased from 50 to 250 g/L, percent …

Influence of Seed Treatment on Tobacco Mosaic Virus Incidence in Tobacco Seedlings and Virus Distribution in Greenhouse Transplant Production
… has been studied for over one hundred years. Seedlings, seed coats, and nutrient solution were assayed for the presence of the virus and seed treatments were tested on seeds. Double antibody sandwich enzyme-linked immunosorbent assay (DAS ELISA) and biological local lesion assay data were …
