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...

Verticillium wilt is a vascular disease of cotton. The causal fungus, Verticillium dahliae, secretes elicitors in culture. We have generated approximately 1,000 5'-terminal expressed sequence tags (ESTs) from a cultured mycelium of V. dahliae. A number of ESTs were found to encode proteins harboring putative signal peptides for secretion, and their cDNAs were isolated. Heterologous expression l...

copper sulfate is one of the most important pollutant in aquaculture systems. the aim of the present study was of the histopathological changes of some organs of common carp. copper sulphate can be considered as a toxic agent for fish.the effect of copper sulphate at 0. 0 1 mg/l as a constant bath was studied on common carp (cyprinus carpio) weighing about 100g. at 19±1°c for one month. tissue ...

The most devastating disease of tomato is bacterial wilt (BW) caused by Ralstonia solanacearum which occur in hot and humid areas of Pakistan. Control of bacterial wilt is difficult, because the pathogen is soil-borne and has a wide host range. There is a need to establish resistance against this pathogen through biotechnological approaches. As a first step, infected tomato leaf samples were co...

the present study aims to report a case of conjunctival necrosis and scleritis due to a subtenon injection of triamcinolone acetonate. a 15-year-old boy received a subtenon injection of triamcinolone acetonate after a pars plana vitrectomy due to an intraocular foreign body. seven days later, conjunctival necrosis and scleritis appeared at the site of injection. no improvement was seen after se...

Bacterial wilt is a vascular wilt disease caused by Xanthomonas translucens pv. poae that infects Poa annua, a grass that is commonly found on golf course greens throughout the world. Bacterial wilt causes symptoms of etiolation, wilting, and foliar necrosis. The damage is most prevalent during the summer and the pathogen can kill turf under conditions optimal for disease development. Fifteen i...
