This review discusses the bioefficacy of natural products (derived from neem and other tropical trees) which have been used against insect pests and diseases attacking forest trees in India. These products are effective, cheaper and eco-friendly and act as antifeedant, repellent, sterility inducing, toxic or regulate insect growth. Integration of these products in forest pest management strategies would enhance the sustainability of forests and prevent the deterioration of wood quality. © 2010 Northeast Forestry University and Springer-Verlag Berlin Heidelberg.

Minor food crops, often known as “poor man's crops,” are currently neglected or underutilized and have become extinct or rare. These crops can, however, contribute substantially to nutritional security in poor communities as they contain essential and trace elements and thrive in harsh climatic and poor soil conditions and show tolerance to water stress, weeds, pests, and diseases. Genetic improvement for food value is therefore needed so as to minimize hunger, malnourishment, and underfeeding. This would be possible with regional and international cooperation for intensive studies, development, and extension. © 2014, Copyright © Taylor & Francis Group, LLC.


Neem-based products including traditional preparations and formulations have been used extensively for the control of insect pests attacking agricultural crops. Content of phytochemicals extracted from different parts of the neem plant varies considerably due to abiotic and biotic factors from collection of the raw material to extract preparation and product formulation. Likewise, effectiveness of crude or synthesized material used in the field or laboratory may be influenced by storage conditions, content of active ingredient (especially azadirachtin), insect species and its growth stage, type of formulation and synergism of products with other control measures. In this paper, the direct and indirect actions of neem phytochemicals on insect pests are described and practical implications for future pest control strategies are discussed. © 2014 Elsevier Ltd.

Crop Protection | Year: 2012

Medicinal plants are attacked regularly by insects, mites, nematodes, bacteria, fungi and viruses. Leaf and seed extracts in water (5-10%), seed cakes (250 kg ha-1), crude oils (0.5-3%) or essential oils (3000 ppm) have been effectively used to control inter alia, the sap sucking pests, foliar diseases and root-knot nematodes. Traditional and commercial products, especially those derived from neem (Azadirachta indica A. Juss.) leaf or kernel, are common in medicinal crops. Since use of plant products including allelochemicals resulted in reasonably effective, ecofriendly and cheaper pest and disease management, and crude extracts are easy to prepare, they may be integrated in crop protection strategies to enhance global exploration of medicinal plants. © 2012 Elsevier Ltd.

Host plants of domesticated silkworms in tropical countries are attacked by an array of insect pests, disease pathogens and nematodes. In order to reduce resulting plant damage, chemicals have been extensively used. In recent years, products extracted/isolated from 47 plant species have been tested as replacements for or to minimize the use of hazardous chemicals. Bioefficacy of the extract in water or chemical solvent, crude seed/leaf oil, and cake is discussed, and integrated management of major and occasional pests and plant diseases is proposed in sericultural plants in order to produce chemical-free foliage. © 2015, Northeast Forestry University and Springer-Verlag Berlin Heidelberg.

The extent and impact of the adoption of improved technology by cotton farmers was assessed during the 2003, 2004 and 2005 crop seasons in the Nagpur and Wardha districts in Maharashtra (central India). The package of improved practices consisted mainly of recommended cultural practices, including the timely application of recommended doses of plant nutrients, the management of water, insect pests and plant diseases in rainfed/dry land, and irrigated cultivation. Precautionary measures for avoiding any possible admixture of genotypes and contamination with dust, dry leaves, pieces of plastic, etc during storage were adopted. The data in project fields compared with non-project/farmers' fields in 164 villages showed a reduction of up to 60% in the cost of plant protection in rainfed cultivation in the Wardha district. In both districts, increases of 20-46% in yield of seed cotton in rainfed and 22-52% in irrigated cultivation, and significant improvement in lint quality were noted. Overall, there was a net profit of Rs5,802- 7,343/ha (US$145-184), or 47-115% in rainfed and Rs6,438-7,561 (US$161-189), or 53-55%, in irrigated cultivation in project fields over non-project fields. These tangible benefits were achieved through awareness programmes held in the project villages on the practicality and cost-effectiveness of improved technology.


The application methods used for the plant-derived products in agricultural crops include seed treatment, mulching of fresh plant material, drenching, trunk injection, soil application of oil cakes and foliar application of extracts. The products derived from neem (Azadirachta indica) have been extensively studied due to their multiple modes of action in insects (antifeedant, deterrent, growth regulator, toxic), plant pathogens (inhibition of spore germination and growth) and nematodes (restriction to root penetration and gall formation). In this review, application methods used singly or integrated with other methods are discussed while considering their practicality and impact on bio-efficacy of the plant-derived products against insects, mites, nematodes and plant pathogens in developing and less-developed countries. Also, the standardization of application methods and equipment is emphasized. © 2016 Springer Science+Business Media Dordrecht

Food security in India is adversely affected by several abiotic, biotic, and sociopolitical situations. The current position may worsen in the future if timely and appropriate actions are not planned and executed. The pressure of human population and land for cultivation, climate change, government policies of public distribution and marketing of food grains, and lack of a participatory approach-all are contributing to slow down the availability of foods. Also, crop productivity seems to be very much unsustainable. The situation has to be remedied by all possible means and citizens must be assured of food security. This review summarizes several strategies for crop production and food distribution and emphasizes the need for a second Green Revolution. © 2011 Copyright Taylor and Francis Group, LLC.

Chemical pesticides are used extensively in gardens and glasshouses to deter or kill insects, nematodes, and various pathogens, and to maintain the quality of flowers required for export or local retail marketing. Since flowers without chemical residues are preferred by customers, alternatives to artificial (man-made) chemicals are being sought. At present, crude plant extracts and oils have been exploited in traditional preparations, and more recently formulated products, especially those based on neem (Azadirachta indica A. Juss.), are available locally at the village level. The potential benefits include economic and environmental aspects, as well as their comparable efficacy. It is hoped that further research and development will result in an increased number of natural plant products being recommended and used in floriculture in the future.
