Evaluation of root-knot nematode disease control and plant growth promotion potential of biofertilizer Ning shield on Trichosanthes kirilowii in the field

Abstract

Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51.08%. Ning shield could also promote the growth of T. kirilowii in the field by increasing seedling emergence, height and the root weight. The results showed that the Ning shield could enhance the production yield up to 36.26%. Ning shield could also promote the plant growth by increasing the contents of available nitrogen, phosphorus, potassium and organic matter, and increasing the contents of leaf chlorophyll and carotenoid pigment. Moreover, Ning shield could efficiently enhance the medicinal compositions of Trichosanthes, referring to the polysaccharides and trichosanthin. Therefore, Ning shield is a promising biofertilizer, which can offer beneficial effects to T. kirilowii growers, including the plant growth promotion, the biological control of root-knot disease and enhancement of the yield and the medicinal quality.

Insights into the Role of Streptomyces hydrogenans as the Plant Growth Promoter, Photosynthetic Pigment Enhancer and Biocontrol Agent against Meloidogyne incognita in Solanum lycopersicum Seedlings

“…They observed that plants treated with S. antibioticus strain M7 showed an enhancement in the levels of pigments due to triggered photosynthetic activities of plants. Moreover, a study reported by Jiang, et al [ 61 ], also revealed that Trichosanthes kirilowii plants infested with nematodes showed an increase in pigment levels upon microbial inoculations. Another study reported by Khanna, et al [ 57 ] suggested that stimulatory effects in their photosynthetic apparatus are due to microbe mediated upregulation in the enzymes responsible for pigment synthesis.…”

Combination of agricultural waste compost and biofertilizer improves yield and enhances the sustainability of a pepper field

“…B. subtilis SM21 is able to colonize and form a biofilm on tomato root surface and control plant disease ( Chen et al., ; Wang et al., ). XY21 was selected for controlling tomato bacterial wilt caused by Ralstonia solanacearum ( Xue et al., ) The consortium generates synergistic activity in controlling different plant diseases such as cotton Verticillium wilt and root‐knot nematode disease ( Yang et al., 2014; Jiang et al., ), and promotes plant resistance to chilling stress ( Wang et al., ). The control efficiency of both pre‐ and post‐harvest disease and the growth promotion, influence on pepper fruit yield and quality, as well as on soil fertility were determined in the present study.…”

Determination of the genus Meloidogyne species and study of their impact on the market gardening in the area of Bamako, Mali

“…They are by far the most formidable, polyphagous that attack the majority of crops resulting in a significant decline in yield. This crop loss has been estimated globally at 14% per year (Groover and Lawrance, 2018), 15-25% or even 75% in some cases according to Jiang et al (2018) great power of multiplication allowing them to quickly invade the roots of the plants on which they cause galls. In terms of money, Phani et al (2017) have estimated the damage caused by these nematodes globally to 173 million Dollars by year.…”
