Actinomycetes are a group of filamentous bacteria that play an important role in the management of plant-parasitic nematodes. Certain species of actinomycetesproduce secondary metabolites that exhibit nematicidal properties, which contribute to nematode management. Actinomycetes control nematodes either directl...
Plant-parasitic nematodes are one of the significant obstacles to the crop production.They are widely distributed and associated with almost all the major agriculture andhorticulture crops and pose a sustainable threat to global food security. These nematodesreduce yields (up to 60%)...
Fusarium is one of the important genera of plant parasitic fungi responsible for causing wilt disease in Soybean. The present study was conducted to identify the virulent isolate of the pathogen and to assess their pathogenicity in Soybean cv. Basara. About 10 different Fusarium...
Microbes play a vital role in influencing the quality and health of soil and plants. Several studies had led to understanding of diversity and structure in the plant rhizosphere: linking with Soil Microbial diversity to Modern Agriculture, amrita gupta et.al (2022); Influence...
Castor is an economically important non-edible oilseed crop grown in tropical and sub-tropical regions of the world and India is the leading producer of castor sharing 65% of world castor growing area (0.75 million ha) with more than 85% of world’s castor product...
Neem enrichment extract (NEE) was used at different concentrations viz., 0, 2.5, 5 and 10% to check its effect on second stage juveniles of Meloidogyne spp. Root knot nematode bio-assay in Petri Plates as well as in pot culture experiments were carried out with NEE.The...
Reniform nematode, Rotylenchulus reniformis is an important nematode associated with castor influencing the productivity of the crop. Efficacy of the leaf extract of Tinospora cordifolia at different concentrations viz., 0.1, 0.5, 1.0, 2.0, 5.0, 10.0 and 20% against the nematode juven...
The cryptic nature of nematodes in Nilgiris has led to their underexplored status, primarily due to the major focus on the Golden Cyst Nematode (GCN), Globoderarostochiensis, infesting potatoes. Moreover, nematodes are abundant creatures on Earth, occupying various feeding and ...
Contour basin irrigation layouts are used in Australia for sequential cultivation of rice and other crops on soils with low infiltration rates. Multiple interconnected basins through gates installed in the check banks and backflow at the inlet end are unique features of cont...
The development of a two-dimensional simulation model for single regular shape ~rectangular! contour basin irrigation layout in southeast Australia is reported in a companion paper. Contour basin layouts as used in Southeast Australia are often irregular in shape and laid out as&...
Impact of elevated CO2 on the rice brown planthopper (BPH), Nilaparvata lugens (Stal.) population and rice yield was assessed in open-top chambers during kharif 2010 and 2011. Brachypterous females laid more eggs (324.3 ± 112.3 eggs/female) on the rice plants exposed&...

The underlying determinants of yield gaps need to be understood for making appropriate policy prescriptions to increase production in the short-run and to eliminate or reduce yield gaps between research station, on-farm demonstration and farmer’s fields. Suitable technologies extend...
The rural youth are disoriented and clueless in the face of lack of income generating and employment opportunities. The problems of young men and women, as well as their vision and aspirations are essential elements of the challenges facing today’s societies and future ...
Abundant biological diversity of India is more vulnerable to the invasion of new insects. The entry of invasive insects is increased across the globe due to the liberalization of trade and increased movement of human beings across the continents. There are 23 different ...

A study was conducted to evaluate the efficacy of 108 rhizobacterial isolates collected from different Oilseed rhizospheres against the wilt pathogen, Fusarium oxysporum f.sp. ricini and reniform nematode, Rotylenchulus reniformis under in vitro conditions. Among the 108 isolates tested, four iso...
Arthropod -related disorders cause signi-ficant health problems to humans, do-mestic animals and wildlife. In addition to causing direct damage by feeding, they act as vectors in transmitting dis-eases. In India, knowledge being gener-ated on insects of economic importance affecting animals and...
A laboratory experiment was carried out to identify optimum formulation medium and temperature for storage of Paecilomyces lilacinus based on spore viability. Paecilomyces lilacinus spores were produced on PDA. paddy grain. sorghum grain and tapioca broth, fonnulated on coconut eoir &...
N Talc and pesta granule formulations of P. lilacinus spores, obtained from solid and liquid media, at 12, 10, 8 and 6 per cent moisture levels were evaluated for their spore viability and tbeir field efficacy, singly and in combination with neem cake against ...
Not: Variability in virulence among entomopathogenic nematodes, Heterorhabditis indica, H. bacteriophora and Steinernema abbasi, was studied for lethality, foraging behaviour in response to host volatiles, thermal requirements (degree-days), recyclability, persistence and field efficacy against Turfgrass Sod&...
Gynaikothrips microchaetus Ananthakrishnan and Jagadish (1969) was described from Dharwar in Karnataka, and until now has been known only from southern India (Ananthakrishnan & Sen 1980). The original description was based on an unspecified number of syntypes, with no depositary i...
