Diseases of ginger and their control with Trichoderma harzianum
TLDR
A biocontrol agent, T.harzianum, isolated from Sikkim was found effective in control of Ginger diseases substantially and the specific chemicals, targeted to particular pathogens ensured the involvement of different pathogens as well as effectiveness of chemicals on control of ginger was diseases.Abstract:
Ginger ( Zingiber officina/e Rosc.), is the second most important cash crop of Sikkim. Diseases are important production constraints and often associated with Ralstonia ( Pseudomonas) solanacearum, Pythium spp., Fusarium oxysporum and Praty/enchus coffeae. Pathogenicity experiments conducted, showed the involvement of Pythium sp (soft rot), Fusarium oxysporum (dry rot) and R.solanacearum ( wilt) and also noticed that, Praty/enchus coffeae increased the severity of infection along with F.oxysporum. From the indirect pathogenicity experiments, the specific chemicals, targeted to particular pathogens ensured the involvement of different pathogens as well as effectiveness of chemicals on control of ginger was diseases. A biocontrol agent, T.harzianum, isolated from Sikkim was found effective in control of ginger diseases substantially.read more

The Effect of Soil Physico-chemical Properties on Rhizome Rot and Wilt Disease Complex Incidence of Ginger Under Hill Agro-climatic Region of West Bengal
TL;DR: Soil having weak acidic reaction with OC percent greater than 2.25 was observed to have the lower average incidence of the disease and organic carbon content and pH of the ginger soil contributed significantly in the prediction of ginger rhizome rot and wilt disease complex incidence with negative correlation.

Selective Isolation of Species of Phytophthora from Natural Soils on an Improved Antibiotic Medium
Peter H. Tsao,Gilberto Ocana +1 more
TL;DR: Most species of Phytophthora do not exist in soil as mycelia, but chiefly as non-mycelial propagules, and so it became apparent why Phytphthora could not be recovered from soil whenever selective media containing pimaricin at 100 p.p.m. were used.

Cross inoculation studies of pseudomonas solana-cearum from ginger
TL;DR: A wilt pathogen of ginger was shouwn to be a weakly virulent form of Pseudomonas - solanacearum, which failed to cause wilt symptoms on tomato, tobacco, or groundnuts; the pathogen was easily recovered from inoculation sites on these plants.
