Brassica species were tested for production of volatile fungicidal compounds from macerated green leaf tissue. Tissue (10, 20, and 40 g) one cultivar each six was assayed inhibition Fusarium sambucinum. Only cultivars B. nigra juncea suppressed radial growth (>50% control). Plant introduction accessions (PIs) juncea, carinata, nigra, napus screened suppression F. carinata PIs had suppressive activity, but activity varied among within these species. The concentration allyl isothiocyanate...
Biostimulant seed coating formulations were investigated in laboratory experiments for their potential to increase maximum germination, germination rate, uniformity, and seedling growth of red clover (Trifolium pratense L.) perennial ryegrass (Lolium perenne seeds. Red seeds coated with different combinations soy flour, diatomaceous earth, micronized vermicompost, concentrated vermicompost extract. Coated non-coated evaluated after 7 10 days, respectively. was maintained at a constant 20 °C...
The Regional Feedstock Partnership is a collaborative effort between the Sun Grant Initiative (through Land Universities), US Department of Energy, and Agriculture. One segment this partnership field-scale evaluation switchgrass (Panicum virgatum L.) in diverse sites across USA. Switchgrass was planted (11.2 kg PLS ha−1) replicated plots New York, Oklahoma, South Dakota, Virginia 2008 Iowa 2009. Adapted cultivars were selected for each location baseline soil samples collected before...
Abstract Switchgrass ( Panicum virgatum L.) has been the principal perennial herbaceous crop investigated for bioenergy production in North America given its high potential, relatively low input requirements, and potential suitability use on marginal lands. Few large trials have determined switchgrass yields at field scale lands, including analysis of costs. Thus, a field‐scale study was conducted to develop realistic yield cost estimates diverse regions USA . Objectives included measuring...
A means for determining the rate of release, Q (spores per square meter second), spores from a source inoculum is paramount quantifying their further dispersal and potential spread disease. Values were obtained Phytophthora infestans sporangia released an area diseased plants in potato canopy by comparing concentrations airborne measured at several heights above source, with predicted Lagrangian Stochastic simulation model. An independent estimate was number unit beginning each sampling day...
To determine if the desert tomato, Lycopersicon pennellii, possesses resistance to late blight, caused by Phytophthora infestans, two plant populations were analyzed. Resistance was identified through assessments of disease progress in an F2 mapping population (L. esculentum × L. pennellii) and a series introgression lines pennellii into esculentum). Levels varied widely among individuals within each population. However, response different strains P. infestans consistent. In population,...
A novel delivery method for the application of bio-based biostimulants as seed coatings was developed using different sources liquid and powder forms vermicompost soy flour. Micronized (MVC) flour (SF) were mixed in combinations dry coating blends applied rotary pan equipment. The physical properties coated seeds measured, binder concentration increased, strength increased. rates percentages germination newly formulations SF+MVC did not decrease parameters significantly than control....
Switchgrass ( Panicum virgatum L.) is undergoing development as a biomass crop to support conversion of cellulosic energy. To avoid the competition with food or feed crops, most commercialization proposals suggest that switchgrass should be grown exclusively on marginal lands are not fit for production. The objective this study was investigate potential cultivar × environment interactions would affect methods and approaches breeding evaluating cultivars, including both upland lowland types,...
Oospores of Phytophthora infestans produced in vitro and planta, from a cross between US-17 US-8 genotypes, were exposed to variety environments their survival was assessed. Additionally, the pathogenic characteristics some resultant progeny isolates Viability oospores as measured by plasmolysis declined slightly over period 18 months whether they stored water at 4°C, soil 18°C, or under natural field conditions. In comparison, viability germination lower overall but appeared increase after...
Ten institutions in nine countries joined together to test the stability of resistance 14 potato genotypes oomycete pathogen Phytophthora infestans three separate trials. Seven were tested one trial involving seven locations, and all two subsequent trials, each eight locations. Stability was with nonparametric tests an additive main effects multiplicative interaction (AMMI) model. Overall, P. robust; resistant consistently locations The analysis indicated that specific basically stable...
Drought conditions after sowing threaten the seedling establishment of all seeds, including cover crops. Cover crops are commonly broadcast and, thus, often susceptible to drought stress sowing. Our hypothesis was that seed coating with superabsorbent polymers (SAPs) would enhance germination in lab and stand field by increasing water availability single seeds. Red clover (Trifolium pratense L.) seeds were coated following selected SAP formulations at 2% their weight: cross-linked potassium...

Oospores were identified in pure culture ofPhytophthora infestansstrains of the clonal lineages US-7 and US-8 (A2 mating type), but not US-1 lineage (A1 type). This self-fertility was due to contamination, a mixture isolates, or heterokaryosis because all single-zoospore isolates (n = 128) from these cultures displayed same phenotype as parental isolate which they derived. The different previously reported forP. infestansand otherPhytophthoraspecies oospores appeared young mycelia appressed...

ABSTRACT Phytophthora infestans is generally regarded as heterothallic-requiring physical proximity of two individuals different mating type (A1 and A2) for oosporogenesis. Recent reports limited selfing in young cultures this oomycete stimulated us to investigate factors contributing the phenomenon. The ability produce oospores rapidly (within 2 weeks) pure, single individual (self-fertility) was tested 116 isolates. isolates were from geographically diverse locations (16 countries)...
Three fungicides were tested in the field for efficacy on late blight caused by Phytophthora infestans. The effects of these epidemic development, lesion growth rate and sporulation measured. No fungicide completely arrested development under environmental conditions experiments. However, mixture, propamocarb hydrochloride plus chlorothalonil, had most suppressive effect tested. mechanism included suppression disease progress expansion. Growth chamber studies demonstrated that 24°C compared...
