The article presents the data on potato agrocenoses affected by Alternaria blight under influence of various factors that have a stressful effect host plant and contribute to damage crop disease. It’s established nematodes increase susceptibility disease, promoting epiphytotic development at earlier stages ontogenesis. Under conditions natural infectious load pathogens weather disease was obser...

Aqueous leaf extract of four different species of Datura viz. D.stramonium L., D. innoxia Mill.Gard, D. metal L. and D. ferox L. Amoen were tested for their antifungal activity against phytopathogenic molds in terms of mycelial growth of Alternaria solani and Fusarium oxysporum f.sp. udum causing early blight of tomato and wilt of pigeonpea respectively. The extract of Datura sp. at 5, 10, 15 a...

Leaf spot and blight disease was observed on two-year-old seedlings of Dendropanax morbifera (Korean name: Hwangchil tree) during July of 2008 in Jindo Island, Korea. Symptoms included yellow-brown to dark brown irregularly enlarged spots frequently located along the veins of leaves. The lesions were often surrounded by chlorotic haloes. Severe leaf blight and subsequent defoliation occurred wh...

We investigated the biocontrol activity of A. pullulans Dmg 30 DEP against Alternaria solani causal agent early blight. Biocontrol was tested by in vivo and ad planta. were investigating antibiosis capabilities with dual culture method, paper dish assay, two-compartment petri trapping identification volatile organic compounds (VOCs) GC-MS. Lysis examined observing clear zone formed growing yeas...

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...

Solanum khasi Clark is a shrub which yields solasodine, a steroidal alkaloid. Transplating of seedlings of S. khasianum during November was found to be favourable for development of Alternaria leaf blight followed by transplanting in December, January and February. This paper presents the findings of the investigation.

Indian Mustard that is emerged as the core oilseed crop cultivated in northern regions of India during Rabi season. Alternaria blight one most destructive pathogens for resulting huge losses quality and quantity produce. A research study was taken up to control alternaria with selected eco-friendly treatments by monitoring disease intensity yield attributes. It noted T2 – Trichoderma viride has...

Rare earth elements have been tested in control of plant diseases. Lanthanum (La) was the Alternaria solani (in vitro) and tomato early blight vivo) using concentration 0; 0.1; 0.2; 0.4 0.8 g L-1. In vitro, were diluted V8 culture medium evaluated for mycelial growth rate index (MGRI) pathogen sporulation. vivo, 24 hours after application inoculate inoculation, leaflets collected quantification...
