KP3, KA1, KB2, WB1, BA2) T (sebelum sesudah patogen), sehingga terdapat 16 perlakuan masing-masing 6 tanaman diulang sebanyak 2 kali,...

The influences of Gaeumannomyces graminis var. tritici (which causes take-all of wheat), Rhizoctonia solani AG-8 (which causes rhizoctonia root rot of wheat), Pythium irregulare, P. aristosporum, and P. ultimum var. sporangiiferum (which cause pythium root rot of wheat) on the population dynamics of Pseudomonas fluorescens 2-79 and Q72a-80 (bicontrol strains active against take-all and pythium ...

Abstract Due to global shifts in climate, studies contrasting conditions of two natural and climatic zones are particular interest: (1) subzone mixed broad-leaved forests, (2) south-steppe subzone. In the period 2019-2020, 308 plant species from 56 families were surveyed. Phytopathogens damage plants, therefore increase loss quality materials. The frequency occurrence mycoses autumn is 2-14 tim...

Ninety seven Rhizoctonia isolates were collected from different Brassica species with typical Rhizoctonia symptoms in different provinces of Vietnam. The isolates were identified using staining of nuclei and sequencing of the rDNA-ITS barcoding gene. The majority of the isolates were multinucleate R. solani and four isolates were binucleate Rhizoctonia belonging to anastomosis groups (AGs) AG-A...

The present study was conducted to detect and identify seed-borne pathogenic fungi in some soybean varieties their effect on seed germination. Six of samples viz.JS 95-60, JS 97-52, RSC 10-46, 10-71, CG Soya-1 local variety were selected for the experiment. Twelve mycoflora viz. Aspergillus flavus, niger, Alternaria spp., Cladosporium Curvularia Rhizopus Trichoderma Rhizoctonia Nigrospora Macro...

Rhizoctonia solani causes crown rot of sugar beets, a severe disease that has destroyed up to 60% of the plants in a test field in western Nebraska. Laetisaria arvalis, a natural hyperparasite of Rhizoctonia spp., was isolated from fields in western Nebraska. To test for the potential for biological control of R. solani, in November 1980 (following harvest) we applied various combinations of a ...
