in vitro and greenhouse studies were conducted to investigate the possibility of an interaction between two systemic insecticides of: thiodicarb (larvin df 80) and imidacloprid (guacho sw 70), and seedling disease organisms of: rhizoctonia solani, fusarium moniliforme and pythium ultimum. when in vitro concentrations of imidacloprid and thiodicarb were applied, a fungistatic activity occurred. ...

UNLABELLED Potatoes are cultivated in southwest Greenland without the use of pesticides and with limited crop rotation. Despite the fact that plant-pathogenic fungi are present, no severe-disease outbreaks have yet been observed. In this report, we document that a potato soil at Inneruulalik in southern Greenland is suppressive against Rhizoctonia solani Ag3 and uncover the suppressive antifung...

some plant extracts have been reported to exhibit antimicrobial properties. plant based pesticides appear to be an alternative for the synthetic pesticides because of their less dangerous impacts. the objective of this study was to assess the inhibitory activity of brassica napus water extract on mycelial growth of six phytopathogenic fungi rhizoctonia solani, phythophtora drechseleri, pythium ...

Two field isolates of Rhizoctonia solani were isolated from infected paddy plants in Malaysia. These isolates were verified via ITS-rDNA analysis that yielded ~720 bp products of the ITS1-5.8S-ITS4 region, respectively. The sequenced products showed insertion and substitution incidences which may result in strain diversity and possible variation in disease severity. These strains showed some re...

Present experiment was conducted at College of Horticulture, Bengaluru (KA) during year 2017–18 to study the cultural, morphological and biochemical variations among isolates pathogen Alternaria solani, causal agent early blight disease in tomato. The results revealed variation collected from different regions Karnataka state, India with regard colony characteristics viz., colour, mycelial grow...

Essential oils from four plants, i.e. geranium, rosa, lemon and mint were tested for their activity in vitro and in vivo against Rhizoctonia solani and Fusarium oxysporum f. sp. phaseoli, the cause of root rot and wilt of beans. In vitro, they were found to have an inhibitory effect against the mycelial growth of R. solani and F. oxysporum f. sp. phaseoli. Complete inhibition in fungal growth w...

Neofusicoccum parvum and Rhizoctonia solani are fungal pathogens with an increasing incidence in young grapevine plants. In this study, the antagonistic potential of some strains genus Trichoderma isolated from against these was investigated at laboratory greenhouse levels. In-plate confrontation assays showed that selected could inhibit mycelial growth both taxa, being more effective N. parvum...

The effectiveness of Clonostachys rosea against Verticillium wilt (Verticillium dahliae) and early blight (Alternaria solani) diseases, as the two most important problems in tomato cultivation with significant economic losses, was determined. It determined that C. effective on A. solani V. dahliae suppressed mycelial growth. Also, wheat grains inoculated to plants at 20 g, 30 40 g concentration...

Cotton is one of the most important fibre plants with much more products being manufactured from it than most other fibre . Apart from fibre, it is used for explosives, cottonwool, etc, and the seed is used principally for the manufacture of oil, soap, animal feed and fertilizers, producing practically no waste. To determine the effective sawdust concentration to inhibit the growth of Rhizocton...
