Phytophthora infestans is a late blight-causing oomycetes pathogen. It rapidly evolves and adapts to the host background new fungicide molecules within few years of their release, most likely because predominance transposable elements in its genome. Frequent applications fungicides cause environmental concerns. Here, we developed target-specific RNA interference (RNAi)-based molecules, along with nanoclay carriers, that when sprayed on plants are capable effectively reducing blight...
Abstract Late blight of potato is considered to be the most devastating problem causing severe yield losses in worldwide. Among different management strategies, use resistant cultivars viable option, but non‐availability enough quantity quality seed materials forces farmers grow susceptible with proper fungicide scheduling. Therefore, present study, chemical control using has been attempted newer molecules cultivar along a as positive control. All tested fungicides were found safe, and no...
Abstract The potato tuber moth, Phthorimaea operculella (Zeller), is a serious pest of and other commercial crops belonging to the Solanaceae family. In recent years, it has become an emerging problem in potato-growing regions Nilgiri hills southern India. It responsible for reduced quality quantity marketable potatoes. this regard, development eco-friendly control method management moth urgently required. Therefore, present study, virulence Steinernema cholashanense CPRSUS01 originally...
The potato cyst nematodes are the most wilful and difficult to manage pests of crop. Due regulatory considerations potential risk involved in environmental health hazards, options for controlling this nematode becoming increasingly limited. Among available management options, trap antagonistic crops offer viable alternative PCN species. Therefore present experiments were conducted determine effect locally crop, Solanum sisymbriifolium against nematodes. Initially, S. was evaluated its crop...
Potatoes are an important source of food for millions people worldwide. Biotic stresses, notably late blight and potato cyst nematodes (PCN) pose a major threat to production worldwide, knowledge genes controlling these traits is limited. A genome-wide association mapping study was conducted identify the genomic regulators biotic prediction accuracy worked out using GBLUP model selection (GS) in panel 222 diverse accessions. The phenotype data on resistance two PCN species (Globodera pallida...
Phytophthora. infestans is a well known late blight causing oomycetes pathogen. It evolves and adapts to the host background new fungicide molecules rapidly within few years of their release, may be due predominance transposable elements in its genome. Frequent huge applications fungicides cause environmental concerns. Here we developed target specific RNA interference based molecules, that are capable effectively reducing infection. cDNA microarray expression data was used for selection...
The potato originated in southern Peru and north-western Bolivia (South America). However, native accessions have also been cultivated India for many years. Late blight, caused by the fungus Phytophthora infestans, is most devastating disease, while cyst nematode (Globodera spp.) (PCN) another economically significant quarantine-requiring pest India. In this study, we generated a new Indian collection of 94 collected from different parts These were screened against late blight resistance...
Potato cyst nematode is the most devastating pest and one of important problem in potato production India as well worldwide. Recently, govt. kept quarantine regulations Jammu Kashmir, Himachal Pradesh Uttarakhand besides Tamil Nadu which shows seriousness this problem. In absence host can survive a protective hard cyst. Under favourable environmental crop conditions infects roots gets their nourishment for development reproduction. As result plant yellowing stunted growth ultimately cause...
Potato cyst nematode (PCN) is considered to be the most devastating pest causing major yield losses in potato worldwide. Resistant cultivars would effective strategy control PCN however, they may not posses enough resistance all pathotypes of PCN. Therefore breeding programme should focus on developing varieties with horizontal which can achieved by using parental lines multiple resistant genes. Hence, present study was conducted characterize phenotypic and genotypic against also an attempt...
The present study investigated the relative transmission efficiency of Potato Leaf Roll Virus (PLRV) by two aphid species on potato. Five aviruliferous aphids both were allowed to acquire PLRV from virus infected potato plant for 96 hrs (Acquisition Access Period) then transferred oneweek old microplants variety Kufri Jyoti and feed hr (Inoculation in order inoculate virus. was terminated spraying imidacloprid 18.5 SL @ 0.03%, plants incubated one month at 26±2°C. tested presence after...
Quarantine species of potato cyst nematodes (PCN), Globodera rostochiensis and G. pallida, were reported from Nilgiris during 1961. The studies carried out at ICAR-CPRS, Muthorai, Ooty ICAR-CPRI, Shimla 2015–17. To investigate the distribution PCN, soil samples collected growing areas identified based on morphological criteria ITS-1 region. Molecular characterization using region specific primers revealed presence pure population in 50% samples, pallida 10.7% mixed 28.6% absence both...
