The present review paper focused on the control of plant diseases by using neem kernel extract. For so many years farmers are extract for pests and in plants Atharvaveda they stated that effectively works diseases. It was controlled seed-borne soil-borne pathogens. early blight wilt tomatoes cowpea. Powdery mildew disease can be Neem has medicinal properties Ayurveda (the ancient book medicine)...

A study was conducted to evaluate the effectiveness of three selected botanicals namely leaf extract of Neem (Azadirachta indica), Debdaru (Polyalthia longifolia) and datura (black) (Datura metel) along with Bavistin (Carbendazim) and BAU-biofungicide (Trichoderma harzianum) against leaf spot disease (tikka) of groundnut caused by Cercospora arachidicola and Cercosporidium personatum at the Fie...

the director of chemistry research at AgriDyne, the products have been accepted very well by growers, and the company continues to receive many requests for the products. Although the neem seems to have endless possibilities, there are some disadvantages that need to be overcome. According to the NRC study, "the truth is that despite all its properties and promise, some impediments must be over...

Induction of systemic resistance by neem cake (Azadirachta indica) and endophytic Pseudomonas aeruginosa, a plant growth promoting bacterium, was evaluated in cotton (Gossypium hirsutum L.) under salinity stress and fungal infection. The combination of biocontrol agent and organic matter induced tolerance against fungal infection (Macrophomina phaseolina) and salinity stress (EC= 17.3 dS, m) by...

The purpose of this study was to compare the antibacterial properties of Azadirachta indica (neem) or Curcuma longa (turmeric) against Enterococcus faecalis with those of 5% sodium hypochlorite or 2% chlorhexidine as root canal irrigants in vitro. The activity of neem, chlorhexidine, sodium hypochlorite, or turmeric against E. faecalis was measured on agar plates using the agar diffusion method...

The present study was designed to investigate the effect of Azadirechta indica (Neem) leaf extract on restraint-induced behavioral deficits and changes in serotonin metabolism in rats. Exposure to a single stress decreased food intake, growth rate and elicited anxiogenic-like behavior on an elevated plus maze. Prior administration of neem leaf extract @ 1 ml/kg for 5 days attenuated stress indu...

The efficacy of different concentrations of aqueous neem leaf extract (3.12 to 50 mg/mL) on growth and citrinin production in three isolates of Penicillium citrinum was investigated under laboratory conditions. Mycotoxin production by the isolates was suppressed, depending on the concentration of the plant extract added to culture media at the time of spore inoculation. Citrinin production in f...

abstract in recent decades the use of environmentally friendly biological and non-chemical materials for the control of plant pests has found good position. due to this reason the effect of some plant extracts (kernel extract of azadirachta indica with 1:12.5, fruit extract of chinaberry, fruit extract of iranian lilac and leaf extract of chinaberry with 1:3 with water), cotton seed oil and nee...

This study presents larvicidal effect of neem (Azadirachta indica) and karanja (Pongamia glabra) oil encapsulated calcium alginate beads (individuals and combination) against mosquito species (Aedes aegypti). Studies were conducted by combining these two oils with and without converting into alginate based encapsulation formulation. Combination (30% neem oil and 70% karanja oil) was found to be...

The Present studies was carried to evaluate the antimicrobial activity against soil microbes which causes corrosion on buried metal in acidic mediated soil by agar well diffusion using aqueous and ethanol extract of Neem leaves. These plants were subjected to solvent extraction with water and ethanol on increasing the polarity to identify and isolate the antimicrobial active materials. Crude aq...
