In 2021, a field experiment was conducted out at ICAR-Krishi Vigyana Kendra in Bengaluru Rural District, Karnataka state, India, to investigate the impact of bio-stimulants on the growth, yield, and quality of chillies (Capsicum annuum L.). The company supplied Lakshmi Hybrid Inputs Seeds Pvt. Ltd. with Chilli Hybrid seeds (LHC-1835), that were utilized to produce the seedlings. In the present investigation, the application of amino acid-based biostimulants was carried out employing a randomized complete block design with seven treatments being replicated three times and spaced 90 by 45 cm apart. The results indicated that the maximum plant height (87.80 cm), primary branches (9.13), secondary branches (18.27), root length (27.07 cm), number of fruits per plant (58.33), fruit length (16.82 cm), and fruit diameter (1.31) with less incidence of pests such as white fly, thrips and murda complex were recorded with seedling dip and foliar application of amino acid-based bio-stimulant.

Multiplex yield enhancers were evaluated in ridge gourd crops at the College of Horticulture in Bengaluru to study their impact on growth parameters, yield parameters, pest and disease incidence. The combination of bio-organic manure, secondary and micronutrients along with biostimulants and recommended dose of fertilizers showed an initial increase in the height of the plant. Treatment T13 showed the highest number of branches (1.44 and 3.11) at 30 and 60 days after planting, while treatment T4 showed the highest number of leaves. Treatment T16, which included Annapurna, Samrddhi, Organic magik, Zinc high, and Navjeevan G recorded the highest number of fruits ( 29) and yield per vine (1768.33 g). Treatment T14 demonstrated a lower percent disease index of powdery mildew at 8.52, while T5 (7.95) recorded a lower percent disease index of downy mildew. Similarly, the treatment that included Bio Jodi reduced the infestation of pests and diseases. The various multiplex yield enhancers worked variably at different stages of the crop as required. The combination of organic and chemical fertilizers works synergistically to improve the yield of the ridge gourd crop.

“…Thus, they can be utilized as components in an integrated disease management approach. However, only a few attempts have been made to evaluate these biorationals and biostimulants as management practices against insect pests in controlling viral diseases [ 53 ]. Hence, considering the research work conducted so far and the existing research gap, the present research has been undertaken to study the incidence of the disease, the molecular characterization of the virus, and the development of management strategies to reduce the incidence of PRSD.…”

Papaya ringspot virus (PRSV) is a significant threat to global papaya cultivation, causing ringspot disease, and it belongs to the species Papaya ringspot virus, genus Potyvirus, and family Potyviridae. This study aimed to assess the occurrence and severity of papaya ringspot disease (PRSD) in major papaya-growing districts of Karnataka, India, from 2019 to 2021. The incidence of disease in the surveyed districts ranged from 50.5 to 100.0 percent, exhibiting typical PRSV symptoms. 74 PRSV infected samples were tested using specific primers in RT-PCR, confirming the presence of the virus. The complete genome sequence of a representative isolate (PRSV-BGK: OL677454) was determined, showing the highest nucleotide identity (nt) (95.8%) with the PRSV-HYD (KP743981) isolate from Telangana, India. It also shared an amino acid (aa) identity (96.5%) with the PRSV-Pune VC (MF405299) isolate from Maharashtra, India. Based on phylogenetic and species demarcation criteria, the PRSV-BGK isolate was considered a variant of the reported species and designated as PRSV-[IN:Kar:Bgk:Pap:21]. Furthermore, recombination analysis revealed four unique recombination breakpoint events in the genomic region, except for the region from HC-Pro to VPg, which is highly conserved. Interestingly, more recombination events were detected within the first 1710 nt, suggesting that the 5’ UTR and P1 regions play an essential role in shaping the PRSV genome. To manage PRSD, a field experiment was conducted over two seasons, testing various treatments, including insecticides, biorationals, and a seaweed extract with micronutrients, alone or in combination. The best treatment involved eight sprays of insecticides and micronutrients at 30-day intervals, resulting in no PRSD incidence up to 180 days after transplanting (DAT). This treatment also exhibited superior growth, yield, and yield parameters, with the highest cost–benefit ratio (1:3.54) and net return. Furthermore, a module comprising 12 sprays of insecticides and micronutrients at 20-day intervals proved to be the most effective in reducing disease incidence and enhancing plant growth, flowering, and fruiting attributes, resulting in a maximized yield of 192.56 t/ha.
