In urban areas garden spaces are reduced in size everyday due to human impact on ecosystem. People living in urban and peri-urban areas don’t have enough space for kitchen gardening or home gardening. The only places that one can grow their own vegetables are terraces and balcony. The main aim of this study is to create awareness on all aspects of growing own organic vegetables and establishment of organic terrace garden. For the establishment of organic terrace garden, space was selected in the department of Botany, Bharathiar University, Coimbatore. The area was covered by using green shade nets. Different sizes of grow bags were selected for the cultivation of vegetables, fruits, greens and medicinal plants. The organic fertilizers and manures like vermicompost, Farm Yard Manure, panchagavya, NPK consortium were used. Neem oil was used to control the pests. Drip irrigation setup was placed in the terrace garden for irrigating the plants. The ornamental plants were planted in the hanging pots and plastic pots to beautify the environment. Students are motivated and trained for the establishment of organic terrace garden and cultivation of vegetables.

The field trials were conducted for two consecutive years during kharif, 2018 and 2019 seasons in the Regional Agricultural Research Station, Warangal, Telangana, India. The susceptible hybrid RCH-2 was grown during both the years of study. Among the treatments, significant (25.4%) reduction of aphids was recorded in neem oil, clothianidin and flonicamid sequential spray. The sequence chlorpyriphos, flonicamid and clothianidin achieved superior efficacy against jassids with 32.3% reduction over control during the two seasons. The highest reduction (25.2%) of thrips was observed in neem oil, clothianidin, flonicamid sequential spray. The incidence of whitefly was low during the experimental period, however, the highest white fly reduction (15.0%) was observed in chlorpyriphos, flonicamid, clothianidin spray. The lowest number of PBW larvae per 10 green bolls was observed in profenophos, spinetoram, chlorpyriphos+cypermethrin sequential spray that reduces up to 61.9% incidence. The lowest number of (38.5) damaged locules per 100 fully opened bolls were observed in profenophos, spinetoram, chlorpyriphos+cypermethrin sequential spray. But, the highest seed cotton yield (1414 kg ha-1) as well as benefit cost ratio (1.02) was recorded in chlorpyriphos, flonicamid, emamectin benzoate, clothianidin, indoxacarb+acetamiprid sequential spray. The study further revealed that, initial control of sucking pests menace especially jassid was crucial in deciding the cotton yield as compared to later stage pink bollworm menace. During both the years, it was noticed that during peak incidence of jassid, the treated plot with flonicamid against jassid in first instance had given highest seed cotton yield.

Acne vulgaris is a chronic dermatological inflammatory disease with symptoms like redness, comedones and blemishes appearing on face and neck. Propionobacterium acnes plays an important role in this disease. Neem oil, an ayurvedic, anti-bacterial medicine is non-comedogenic. Concealer is a type of cosmetic used to mask and camouflage blemishes and imperfections visible on skin and are available as liquid, balm, cream and stick. BB creams in cosmetics is termed as “beauty balm, blemish base, blemish balm” designed to serve as foundation, moisturizer and sunscreen all at once. The current study was to develop an aesthetic BB cream combining an anti-acne activity with concealing effect. Concentrations of upto 25 %w/w neem oil was prepared and evaluated for appearance, texture, pH, spreadability, antibacterial properties and in vitro release studies. All the formulations confirmed activity against P. acnes. Prolonged activity of neem oil observed at the end of 6 h as demonstrated in vitro

Chronic nonhealing leg ulcers are debilitating with high morbidity in a vulnerable patient population and pose a frequent clinical and socioeconomic problem. Numerous local treatment options exist, but clinical trials are rare and wound management still represents a big challenge. Recently a wound dressing based on the natural remedies Hypericum perforatum and Neem oil has been proposed for chronic wound management, but trials on nonhealing leg ulcers are missing. Uncontrolled retrospective observational case review on all patients under our supervision with chronic leg ulcers who underwent treatment with a plant-derived wound dressing based on Hypericum perforatum and Azadirachta indica (Neem) oil. It could be retrieved in a total 16 cases (11 female) with a median age of 71 years. All ulcers (7 ulcers on the leg and 9 ulcers on the feed) showed a complete healing after a median healing time of 82 days (Mean 85, range 14-180 days). No side effects occurred, medication was painless or even reduced pain. Wound dressings based on Hypericum perforatum and Neem oil are well tolerated and could be a potential additional simple treatment option in the management of non-healing leg ulcers. Prospective controlled trials are needed to confirm these observations.

Bagrada hilaris (Burmeister) is a serious pest of Brassica crops in the North-Western region of India, inflicting crop yield losses. Therefore, the present study was conducted on seasonal incidence and management of B. hilaris in Brassica juncea genotype RH 725 at farmer’s field, Kolana village, Aravalli Hills Region, Rewari, Haryana, India during Rabi, 2019-20 and 2020-21. This study laid out the trial in a randomized block design with three replications and six treatments viz., Neem Seed Kernel Extract (NSKE) @ 7%, Nimbecidine @ 0.03%, Neem oil @ 5%, NSKE @ 5%, Neem oil @ 7% and control (unsprayed). Observations on the incidence of B. hilaris showed that it appeared from 5th Standard Meteorological Week (SMW) (0.34 bugs plant-1) and attained peak during 10th SMW with 5.77 bugs plant-1. The incidence of B. hilaris exhibited significant positive correlation with maximum (r=0.852, p<0.05) and minimum (r=0.900, p<0.05) temperature, rainfall (r=0.763, p<0.05) and wind velocity (r=0.959, p<0.05). Spray of Neem oil @ 7% (83.01 %) was the most effective in reducing the B. hilaris population over control followed by NSKE @ 7% (81.48 %), while NSKE @ 5% (68.85 %) confirmed least effective. Seed yield in different treatments varied from 1440.5 kg ha-1 (NSKE @ 5%) to 1590 kg ha-1 (Neem oil @ 7%) against 1216 kg ha-1 in control. The highest incremental cost-benefit ratio was registered with NSKE @ 7% (1: 7.70) followed by Nimbecidine @ 0.03% (1: 7.41) and NSKE @ 5% (1: 6.25). The present investigation signified that the study on the seasonal incidence of B. hilaris in relation to weather parameters could provide information for planning pest control and management strategies. The botanicals could be used as eco-friendly and economical substitutes for chemical insecticides at farmer’s fields against this insect pest.

Galleria mellonella larvae feed on wax, pollen, honey and damage the combs with in active bee colonies and storage condition. Galleria mellonella larvae can bore tunnel and feed around the midrib base of the wax comb. Larvae produce silk fibers that can trap bee brood cells. Comb is completely covered with webbing and extracted matter of the larvae condition described as “Galleriasis”.  The study was carried out at Apiculture Lab of RVSKVV-ZARS-Krishi Vigyan Kendra, Morena (M.P.) during 2019-20. Different three concentration of bio-pesticides viz., Bacillus thuringiensis Kurstaki  (1, 1.5 and 2%), custard apple seed extract (2, 4and 6%) and Neem Oil (1, 2 and 3%) were used against the Galleria mellonella to assess the effect of larval mortality at 24, 48, 72 and 96 hours after treatment. There was no significant effect showed in all the treatments after 24 hours. The maximum mortality of Galleria mellonella larvae was recorded in Bacillus thuringiensis Kurstaki 2.0 percent concentration (46.67, 87.08 and 96.67%) after 48, 72 and 96 hours respectively and it was at par with custard apple seed extract 6.0 percent concentration (45.83, 85.0 and 93.75%). Neem oil 3.0 percent concentration expressed 38.33, 75.42 and 87.50 percent larval mortality after 48, 72 and 96 hours respectively. Whereas minimum mortality was noticed in Neem oil 1.0 percent at 48 hours (22.08%), at 72 hours (37.08%) and at 96 hours (56.25%) among the treatments. The higher concentration of all the three bio-pesticides was proved effectiveness against Galleria mellonella during investigation.

Indian mustard (Brassica juncea (L.) Czern.coss) is also known as sarson, rai or raya, toria or Lahi.it is a herbaceous annual plant. Mustard is the second important oilseed crop in the world after sunflower, soybean and palm oil. Alternaria blight disease caused by Alternaria brassicae (Berk.) Sacc. It has been reported from all the continents of the world. Average yield losses occur due to various pest and diseases among which Alternaria blight is an important disease. Field experiment was conducted at the research plot of the Department of Plant Pathology, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh during the rabi season of 2020-2021 to test, Effect of selected essential oils and botanicals against Alternaria blight (Alternaria brassicae (Berk.) Sacc) of mustard (Brassica juncea (Linn.) Czern and Coss), by foliar spray of certain essential oil, plant extracts and fungicide. The treatments were Neem oil @2%, Eucalyptus oil @2%, Pongamia oil @2%, Lawsonia inermis extract @15%, Chenopodium album extract @15% Mancozeb (treated check) @ 0.2% and control (untreated check). The percent disease intensity on leaves at 45, 60 and 75 DAS, number of siliquae per plant, number of seeds per siliquae, length of siliquae (cm), test weight of seed (1000 number), biological yield (gm) and seed yield were recorded. Among the treatments, maximum number of number of siliquaes (243.13), maximum number of seeds per siliquae (12.27), length of siliquae (5.16 cm), minimum disease intensity (%) (29.01 %), maximum test weight (3.57 gm), maximum yield (9.43 qt) and biological yield (24.70 gm) were recorded in the treatment T2 Eucalyptus oil @2% followed by T1 Neem oil @2%, T4 Lawsonia inermis  extract @15%, T3 Pongamia oil @2%, T5 Chenopodium extract @15%, when compared to treated check T6 Mancozeb @ 0.2% and untreated check T0. Higher gross return value (Rs. 66295), net return value (Rs. 29295), and B: C ratio (1.7:1) was found in the treatment T2 – Eucalyptus oil @2% as compared to T5–mancozeb and T0–control.
