An undescribed species of Raffaelea earlier was shown to be the cause of a vascular wilt disease known as laurel wilt, a severe disease on redbay (Persea borbonia) and other members of the Lauraceae in the Atlantic coastal plains of the southeastern USA. The pathogen is likely native to Asia and probably was introduced to the USA in the mycangia of the exotic redbay ambrosia beetle, Xyleborus g...

Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...

Bacterial wilt (BW) is a serious disease that affects eggplant (Solanum melongena) production. Although resistance to this disease has been reported, the underlying mechanism is unknown. In this study, we identified a NAC family transcription factor (SmNAC) from eggplant and characterized its expression, its localization at the tissue and subcellular levels, and its role in BW resistance. To th...

Background The state of Espirito Santo has in the fruit growing, one of its main economical activities. One of them, the pineapple growth, represents a good economic potential to increase income and job opportunities in the state. However, diseases such as fusariosis and mealybug wilt of pineapple are responsible for the yield losses of up to 80% [1]. The mealybug wilt of pineapple is caused by...

Among the single treatments tested under in vivo addition of well decomposed FYM 20 tons per hectare as soil amendment recorded minimum wilt incidence of 3.75, 24.76 and 48.25 % at flowering, fruit formation and ripening stages of chilli crop, respectively, with 61.31 q ha fruit yield as compared to check (42.50 q ha). Dual application of Trichoderma viride 0.16 t ha + FYM 20 t ha recorded mini...

Bacterial wilt is a common disease that causes severe yield and quality losses in many plants. In the present study, we used the model Ralstonia solanacearum-Arabidopsis thaliana pathosystem to study transcriptional changes associated with wilt disease development. Susceptible Col-5 plants and RRS1-R-containing resistant Nd-1 plants were root-inoculated with R. solanacearum strains harbouring o...

Verticillium wilt of cotton is a widespread and destructive disease that is caused by the fungus pathogen Verticillium dahliae. Although no cotton cultivar is immune to the disease, some genotypes exhibit superior wilt tolerance. To gain an insight into the molecular mechanisms responsible for wilt tolerance, we employed the method of suppression subtractive hybridization (SSH) to isolate genes...

Peroxyacetic acid mixture Perosan, composed of peroxyacetic acid, hydrogen peroxide and acetic acid, was evaluated for eco-friendly management of tomato bacterial wilt by Ralstonia pseudosolanacearum. Perosan drastically suppressed in vitro growth of R. pseudosolanacearum in liquid cultures in dose- and incubation time-dependent manners. Higher perosan doses (0.1 and 1%) caused lowered pH and p...

Bacterial wilt caused by plant pathogenic Ralstonia spp. is one of the most important diseases affecting the production of many important crops worldwide. In China, a large scientific community has been dedicated to studying bacterial wilt and its causative agent, Ralstonia pseudosolanacearum and R. solanacearum. Most of their work was published in Chinese, which has hindered international comm...

Two field experiments (Spring, 1974 and 1975) were conducted on Myakka fine sand to determine the effect of lime and nitrogen source on the development of Fusarium wilt of cucumber and watermelon. The same site, with the same experimental design, was used for each experiment. In both experiments, gross yields were increased and wilt development decreased by raising the soil pH with hydrated lim...
