Fungicide difenoconazole is applied for field treatment to protect potato and tomato against early blight, caused by the Alternaria fungi. It is practically important to estimate the impact of difenoconazole application against late blight pathogen Phytophthora infestans (Mont.) de Bary because of early and late blight often come together on potato. Effect of fungicide difenoconazole on the rad...

Effluent from electroplating industry involved in copper plating and other metal polishing work contain various heavy metal(Cu, Fe, Ni, Pb, Mn and Zn) which have severe adverse effect on health . The present work analyzes heavy metal present in plating shops for a period of one year. Highest copper metal concentration (27.60mg/L) was observed during post monsoon at site AB-5, least copper metal...

Antifungal activity of ethanol-water extracts of four medicinal plants, cinnamon (Cinnamomum verum Presl.), anise (Pimpinella anisum L.), black seed (Nigella sativa L.) and clove (Syzygium aromaticum L. Merr. & Perry.) was investigated against pea (Pisum sativum L.) root-rot fungus Rhizoctonia solani. In vitro antifungal activity test shown a high growth inhibition at concentration (4%) of each...

in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...

In this report, the effects of two oligochitosans, i.e., oligochitosan A (OCHA) and oligochitosan B (OCHB), on control of dry rot of Zanthoxylum bungeanum (Z. bungeanum) caused by Fusarium sambucinum (F. sambucinum) were evaluated. First, both oligochitosans show desirable ability to decrease the infection of F. sambucinum. Second, the oligochitosans strongly inhibit the radial colony and subme...

the botrytis cinerea is one of the most important agents of strawberry fruit rot. in order to identify the pathogenicity potential of the isolates on fruits and the antifungal effect of anise essence on this fungus, forty one isolates of b. cinerea was collected from different areas of mazandaran province on strawberry showing symptoms of gray rot on fruits. following the purification of the fu...

potato is one of the main crops which is suffering from the great losses in storage and the most conventional method of its tuber rot is using hazardous chemicals. using antimicrobial potential of lichens can be one of the safe, green, environment friendly methods for plant diseases management. in this study, antimicrobial activity of acetone, methanol, chloroform extracts of ramalina capitaat,...

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 myce...

Experiments were carried out to test the aqueous extracts of twenty plants for their antifungal activity against Fusarium solani the causal of dry rot disease of potato. The obtained results showed a differential activity of the plant extracts against the mycelium growth. The combined leaf extracts of Lawsonia alba and stem extracts of Acacia catechu in general showed a strong enhancement in ac...

BACKGROUND Fusarium oxysporum has worldwide distribution and causes severe vascular wilt or root rot in many plants. Strains are classified into formae speciales based on their high degree of host specificity, of which multilocus sequence typing provides a fairly good estimate. AIMS The main aim of this study was to identify the causal agent of an infected potato tuber in Colombia. METHODS ...
