Balloon flower (Platycodon grandiflorum) is a kind of mountain herbs whose roots have restorative properties and the cultivating acreage of balloon flower has been steadily increasing in Korea. More frequent rain and high amount of rainfalls as a result of climate changes predisposed balloon flower to the outbreaks of root rot at high-density cultivation area in recent years. Root crowns were u...

BACKGROUND Blind and excessive application of fertilizers was found during the cultivation of Panax notoginseng in fields, as well as increase in root rot disease incidence. METHODS Both "3414" application and orthogonal test designs were performed at Shilin county, Yunnan province, China, for NPK (nitrogen, phosphorus, and potassium) and mineral fertilizers, respectively. The data were used ...

PROCEDURES: We conducted two studies to investigate an integrated program for root rot (Phytopthora fragriae var. rubi) control in raspberries that would be useful to organic and conventional growers. These two studies have been carried out on our commercial field of ‘Meeker’ that was established in 1997 on raised beds with drip irrigation. Soil at this site is naturally infested with the root ...

in vitro studies with trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. microscopic observations showed that t. harzianm and t. viride, isolated from soil samples from ahwaz and karaj, adversely affected the mycelial ...

The widespread destruction of commercially grown bulbs of Narcissus tazetta papyraceus (Paper White) has been reported in Israel. This phenomenon is usually characterized by a premature yellowing of the foliage, accompanied by root rot and dark, sunken basal plates. This study confirmed thatAphelenchoides subtenuis is the main cause of the basal plate disease of Narcissus. In contrast to other ...

This paper describes the specifics of forests on former farmlands in Poland and their protection as well as preventive measures taken. The review refers to polish literature on the threat by root rot caused by Heterobasidion annosum (Fr.) Bref. to pine and spruce plantations established on postagricultural lands on an area of more than 1400 000 ha. In Europe, the latter presents an outstanding ...

The use of microorganisms and their secreted molecules to prevent plant diseases is considered an attractive alternative and way to supplement synthetic fungicides for the management of plant diseases. Strain BS062 was selected based on its ability to inhibit the mycelial growth of Botrytis cinerea, a major causal fungus of postharvest root rot of ginseng and strawberry gray mold disease. Strai...

to identify the fungi associated with foot and root rot of wheat in the khuzestan province, diseased samples were collected at all growth stages in three growing seasons of 2004-2007. pieces of infected parts of the root and foot were surface sterilized and cultured on acidic and non acidic pda media. one hundred and fifteen isolates were obtained and on the basis of macroscopic and microscopic...
