Abstract:

<em>Damping-off, root and/or stem blights caused by oomycetes of the Phytophthora genus are one of the most important groups of the most destructive diseases of cultivated plants, in particular legume crops. More than 15 species of this genus can infect species of beans, mungbean, soybean, cowpea and other legumes. No one of these species have been registered on legumes in Uzbekistan, but in our country, there are some other species of the genus that affect other crops (potatoes, tomatoes), so the danger of their accidental introduction into the territory of the republic is not excluded.

Abstract:

The assessment of alien invasive species of Phytophthora genus causing serious forest tree species diseases was carried out in Lithuania. The presence of Phytophthora DNA was recorded for the first time using real-time PCR analysis on 23 DNA samples. The sampling included wood from diseased trees, leaves from shrubs, leaves baited in water, and soil samples taken around diseased plants. Extracted DNA from soil and plant tissues was tested for the presence of Phytophthora. All analysed samples were positively recognized by Phytophthora-specific probe during real-time PCR which proved the presen

The multidisciplinary ‘Phyto-threats’ project was initiated in 2016 to address the increasing risks to UK forest and woodland ecosystems from trade-disseminated Phytophthora. A major component of this project was to examine the risk of Phytophthora spread through nursery and trade practices. Close to 4000 water and root samples were collected from plant nurseries located across the UK over a three-year period. Approximately half of the samples tested positive for Phytophthora DNA using a metabarcoding approach with 63 Phytophthora species identified across nurseries, including quarantine-regul

Abstract:

Phytophthora is a genus of microorganisms that cause devastating dieback and root-rot diseases in thousands of plant hosts worldwide. The economic impact of Phytophthora diseases on crops and native ecosystems is estimated to be billions of dollars per annum. These invasive pathogens are extremely difficult to control using existing chemical means, and the effectiveness of the few treatments available is being jeopardized by increasing rates of resistance. There is an urgent need to identify new chemical treatments that are effective against Phytophthora diseases. Natural products have long be

Abstract:

Plant diseases caused by Phytophthora species will remain an ever increasing threat to agriculture and natural ecosystems. Phytophthora literally means plant destroyer, a name coined in the 19th century by Anton de Bary when he investigated the potato disease that set the stage for the Great Irish Famine. Phytophthora infestans, the causal agent of potato late blight, was the first species in a genus that at present has over 100 recognized members. In the last decade, the number of recognized Phytophthora species has nearly doubled and new species are added almost on a monthly basis. Here we p

Abstract:

Rotting diseases caused by pathogens can result in losses for farmers of sweet oranges (Citrus sinensis). Natural control is necessary to reduce the side effects of the use of chemical fungicides. The purpose of this study was to find out the interaction between pathogenic fungi (Phytophthora sp) with antagonist mushrooms (Trichoderma sp) in Petri cups and to know the effectiveness of antagonistic fungi (Trichoderma sp) in inhibiting the growth of pathogenic fungi (Phytophthora sp) with dual culture tests. Antagonist test with dual culture method is conducted on PDA pH 5 media by measuring the

Abstract:

Black pod rot is the most economically important disease of cocoa in Malaysia which is mainly caused by a highly polyphagous Phytophthora species, called Phytophthora palmivora. The fungus could attack all parts of the cocoa plant organs and caused various diseases at any growth stage from seedling until the mature stages, especially during raining season. The application of synthetic fungicides has been widely recommended to manage the disease but their repeated use had led to other problems such as environmental, human health and development of fungicide resistance issues.

Abstract:

A severe rot of sugar beet roots was observed in the Amyndeon area of Greece during summer 1998. Infected plants initially showed a temporary wilt, which became permanent, and finally died. Slightly diseased roots showed necrotic spots toward the base, whereas more heavily diseased roots showed a more extensive wet rot that extended upward. Feeder roots also were infected and reduced in number because of decay. Rotted tissue was brown with a distinguishing black margin. In most of the isolations, carried out on potato dextrose agar (PDA), the pathogen obtained was identified as Phytophthora cr

Abstract:

Three damaging soybean diseases, Sclerotinia stem rot caused by a fungus Sclerotinia sclerotiorum (Lid.) de Bary, Phytophthora root rot caused by a fungus Phytophthora sojae, and soybean cyst nematode (Heterodera glycines Ichinohe), are destructive to soybean growth and yield and cause huge economic losses. Biocontrol is an effective way to control soybean diseases with the advantage of being environmentally friendly and sustainable. To date, few reviews have reported the control of these three soybean diseases through biocontrol measures. In this review, the biological characteristics of the

Marine oomycetes have recently been shown to be concurrently infected by (−)ssRNA viruses of the order Bunyavirales. In this work, even higher virus variability was found in a single isolate of Phytophthora condilina, a recently described member of Phytophthora phylogenetic Clade 6a, which was isolated from brackish estuarine waters in southern Portugal. Using total and small RNA-seq the full RdRp of 13 different potential novel bunya-like viruses and two complete toti-like viruses were detected.

This research shows that the severity of Phytophthora root and crown rot of cucumber caused by Phytophthora capsici was suppressed significantly in cucumber transplants produced in a composted cow manure-amended mix compared with those in a dark sphagnum peat mix.

The discovery of disease suppression in certain bark composts increased the interest in using compost as growing substrate to control root rot diseases caused by Phytophthora cinnamomi. Disease suppression mechanisms include antibiosis, competition, hyperparasitism, and induced systemic resistance. Although abiotic factors may influence disease suppression, the latter is often based on microbial interactions—the two common mechanisms being general for pythium (Pythium spp.) and phytophthora root rot (Phytophthora spp.) and specific for rhizoctonia (Rhizoctonia solani).
