Management ofBittergourd yellow mosaic virus(BGYMV) by using virus inhibiting chemical, biocontrol agents, antiviral principles (AVP) and insecticide

Abstract

Bitter gourd Yellow Mosaic Virus (BGYMV) is a Whitefly transmitted geminivirus. BGYMV causes yellow mosaic disease in bitter gourd. This disease attains significance because the virus causing this disease is capable of attacking the crop at all stages. There was a severe yield loss in bitter gourd plants due to the infection of BGYMV. Bitter gourd plants treated with Bougainvillea spectabilis challenge inoculated with BGYMV reduced the disease incidence and increased the plant growth. In the above treatment the disease incidence was 33.33% at 75 Days After Sowing (DAS). But in the inoculated untreated control the disease incidence was 100% at 75 DAS. The mean maximum plant height was 92.24 cm in plants inoculated at 65 DAS. Bougainvillea spectabilis treated plants challenge inoculated with BGYMV showed an increased activity of peroxidase, polyphenoloxidase and phenol content from 4 Days After Inoculation (DAI) to 12 DAI. The activity of all the enzymes was reduced from 16 DAI in all the treatments.

Biochemical Alterations in Different Pigeon Pea Genotypes due to Sterility Mosaic Disease

“…Similar results reported by Chatterjee and Ghosh (2008) in Mestha against yellow vein mosaic disease. Rajinimala et al, (2009) and Anuradha et al, (2015) also discovered similar results in bitter gourd against yellow mosaic virus, in banana against bunchy top virus.…”

Plant Growth-Promoting Rhizobacteria (PGPR) as Biocontrol Agents for Viral Protection

“…BGYMV, being a Geminiviridae family member (Begomovirus genus), is a disease-causing virus causing an effect on the loss of yield due to vector whitefly, Bemisia tabaci. To control the disease, initiation of systematic infection resistance method in the bitter gourd crop counter to BGYMV is used (Rajinimala et al 2009). The infection rate has reliably decreased at 45 days after planting DAS by seed treatment with P. fluorescens and P. chlororaphis, and further, it is essentially diminished at 75 DAS contrasted with immunized control plants (untreated) (Rajinimala et al 2009).…”

UTILIZATION OF PLANT EXTRACTS TO SUPPRESS Squash Mosaic Virus INFECTION ON RIDGED GOURD (Luffa acutangula [L.Roxb])

“…It is indicated that BS and AS have a positive effect on plant growth. Similarly, bitter gourd plants treated with B. spectabilis (BS) challenge inoculated with bitter gourd yellow mosaic virus (BGYMV) reduced the disease incidence and increased plant growth (Rajinimala et al, 2009). Salicylic acid is known as an inducer of plant defense responses against pathogens.…”

“…The protein's mode action to suppress virus infection in plants is through activation of antiviral by ribosome-inactivating proteins (RIPs) and ISR (Vivanco et al, 1999). Plant extracts able to suppress the infection of viruses such as Cucumber mosaic virus (CMV), Tobacco mosaic virus (TMV), Tomato mosaic virus (ToMV), Tomato spotted wilt virus (TSWV), Potato virus Y (PVY), Potato virus X (PVX), Potato leafroll virus (PLRV), Potato tuber spindle viroid (PSTVd), Cucumber green mottle mosaic virus (CGMMV), Turnip mosaic virus (TuMV), Bitter gourd yellow mosaic virus (BGYMV) and Bean common mosaic virus (BCMV) (Balasarawathi et al, 1998;Balasubrahmanyam et al, 2000;Baranwal & Verma, 1997;Damayanti & Panjaitan, 2014;Deepthi et al, 2007;Gholizadeh et al, 2004;Hersanti, 2004;Kubo et al, 1990;Kumalasari et al, 2015;Kurnianingsih & Damayanti, 2012;Madhusudhan et al, 2011;Rajinimala et al, 2009;Sharma et al, 2007). The effectiveness of plant extracts to suppress the virus infection is depends on the virus species.…”
