Abstract:

Four compounds namely Fenor (F-760), Strom, salicylic acid (SA) and thiamin (B1) were tested against root rot disease of wheat under field condition. Wheat grains were soaked in these compounds for 6 h before sowing. Mean disease rating, disease appearance, and distribution of disease were estimated as parameters of disease severity. All tested compounds significantly reduced the root rot of wheat severity during seedling, flowering and ripening stages. Fresh and dry weights were also affected by application of these compounds.

Abstract:

The effect of soil tillage on plant growth, yield and root rot severity of beans was investigated in field plots with and without root rot infestation in 1992 and 1993. There was a significant reduction in root rot severity, and an increase in plant dry weight and yield in the root-rot-infested soils with deep tillage in both years. Deep tillage also significantly increased plant dry weight and yield in the non-root-rot soils in a dry year. The resistant cultivar (A300) had significantly less root rot damage than the susceptible cultivar (Harowood) in both root rot and non-root rot infested so

Abstract:

The rutabaga, also known as the swede turnip, is grown on ≈2000 ha in Canada. During the spring of 2006, a grower in Prince Edward Island noticed an advanced level of decay in his stored rutabagas (cv. Thompson Laurentian). About 80% of the stored crop was affected. Lesions on the surface of affected roots were circular to ovate and ranged in size from 10 to 50 mm. The lesions were light brown, with dark borders and some concentric zones evident near the perimeter of the affected tissue. Root tissue within the lesions was shrunken and often wrinkled. Sectioning the root through the lesion reve

Abstract:

The aqueous extracts of leaf of Citrus aurantifolia L were assessed in vitro for inhibitory activity against Macrophominaphaseolina isolated from dry root rot specimens of Gingelly. The antifungal activity was determined by poison food technique. The extracts have shown dose dependent inhibition of mycelial growth of test fungi. The extracts were more effective in inhibiting Macrophominaphaseolina. The extracts of Citrus aurantifolia were found effective against Gingelly dry root rot pathogens. Further field experiments are to be carried out to recommend the extracts against the disease.

Abstract:

An investigation was conducted on chickpea (Cicer arietinum L.) genotype JG-62 to study the effect of different abiotic factors on the incidence of dry root rot. Maximum disease incidence was observed at 35°C temperature while minimum disease incidence was observed at 20°C. More disease incidence was observed at low moisture conditions while low at high moisture conditions. Soil pH also influenced the disease incidence. Maximum disease incidence was observed at pH 4.5 while minimum disease incidence was observed at pH 7.5. The results are useful for managing the incidence of dry root rot in ch

Fusarium semitectum was found to be the major seed colonizing fungus in the commercial acid delinted cotton (Gossypium hirsutum) seed lots.

Inoculation technique simulating internally seedborne nature of the fungus showed that the observed non-correlation might be related to the threshold level of seed coat colonization. The internally seedborne inoculum besides reducing seedling emergence, incited an array of symptoms on the emerged seedlings, which

Rhizoctonia root and hypocotyl rot is a common disease of soybean caused by Rhizoctonia solani. There are no commercial cultivars marketed as resistant to Rhizoctonia root and hypocotyl rot, and only a few sources of partial resistance to this disease have been reported. Ninety ancestral soybean lines, maturity groups (MGs) 000 to X, and 700 commercial cultivars, MGs II to IV, were evaluated for resistance to R. solani under greenhouse conditions. Most of the ancestral lines and cultivars evaluated were susceptible; however, 21 of the ancestral lines and 20 of the commercial cultivars were par

Little is known about how mulching and frequent waterlogging affect disease severity in blueberries. Phytophthora cinnamomi Rands was grown on rice hulls, which were incorporated into the soil at the rate of 10% (v:v). Waterlogging conditions were imposed for 48 hours 1 week after planting on mulched and nonmulched blueberry plants at weekly, biweekly, and monthly intervals for a total of 3 months. Control plants were not subjected to flooding. The severity of Phytophthora root rot increas

Abstract:

Fusarium root rot is a major limiting factor in snap bean (Phaseolus vulgaris L.) production. The level of genetic resistance in commercial bean cultivars is minimal and disease is frequently exacerbated by environmental factors. We investigated the contribution of vigorous, adventitious roots to enhancing root rot tolerance in snap bean. Seedling root system architecture was evaluated in 17 recombinant inbred lines (RILs) from a cross of a resistant snap bean line (FR266) and a susceptible dry bean cultivar (Montcalm). The RILs varied in tolerance to Fusarium root rot. Although overall length

In Queensland, Australia there was evidence of tolerance in the wheat cultivar Banks across two locations, but the response was not consistent in all cultivars. Dry matter loss at immature growt

The herbicide trifluralin increased both the incidence and severity of root rot in four Medicago truncatula cultivars and reduced their dry matter production. In glasshouse studies with a naturally infested soil from Kaniva, medic root disease was controlled by soil incorporation of metalaxyl but not by soil treatment with benomyl. The known biological activity of metalaxyl suggests that the fungi responsible for the root rot were Peronosporales.

Chickpea is an essential crop for protein nutrition and is grown around the world in rain-fed conditions. However, chickpea cultivation is under threat due to emerging diseases favored by drought stress. Dry root rot (DRR), an economically devastating disease, is an example. Chickpea-specific strains of a necrotic fungal phytopathogen, Macrophomina phaseolina, cause DRR. Microsclerotia of this fungus, which are capable of withstanding harsh environmental conditions, serve as primary inoculum. Initial symptoms are scattered necrotic spots in roots, progressing to rotting and withering lateral r

Twelve soybean varieties were also assessed for resistance to seedling blight and tolerance to Fusarium root rot. All treatments except Vibrance + Apron XL improved emergence.

In Michigan, yield reduction as a result of diminished plant vigor owing to root rot is a major constraint associated with dry bean production and is exacerbated when fields have a history of short crop rotations. Replanting can be necessary when flooding, poor seed germination, or cool soil temperatures result in poor plant establishment, which may be compounded by increased disease pressure. To identify which soilborne pathogens are associated with root rot disease complex on dry bean and to determine their prevalence, a survey was conducted from 2014 to 2018.
