Current study undertaken to find out the insecticidal properties of essential oils extracted from two local plants namely Jasmine Jasminum grandiflorum (Fam. Oleaceae) and Basil Ocimum basilicum Var, (Fam. Lamiaceae) against two of major stored insects (Tribolium castaneum, and Rhyzopertha dominica). Results showed that for T. castaneum basil absolute had the strongest contact effect at all exposure periods of exposure with LC50 of (2690.0, 2270.0 and 1735.0 mg/kg) after 24, 48 and 120 h of exposure, respectively. Also showed that all tested essential oils had an effect on adults of R. dominica. However, basil absolute had the strongest effect with LC50 of (489.8 and 842.7 mg/kg) after 48 and 24 h of exposure, respectively. Based on LT50 values for T. castaneum basil absolute had the strongest effect with LT50 of 0.34 h, However for R. dominica all tested essential oils had an effect and with the highest concentration (5000 mg/kg) basil absolute had the strongest effect with LT50 of 6.60 h. The results show that all tested essential oils had an inhibition effect on T. castaneum at all concentrations. With the highest concentration (7500 mg/kg) basil oil had the strongest effect with 100% reduction. The results show that all tested essential oils had the same inhibition effect on R. dominica at all concentrations with 100% reduction.
This study has the objective to standardize the optimal nutritional and physical parameters associated with the growth and sporulation of fungal biological control agent named C. rosea. Among the six isolates of biocontrol agent, TNAU CR 01 was used in the present study. The effects of different substrates amended on nutritional medium were tested for the growth of fungal mycelium by petri plate method. Different temperature range was maintained to found the optimal environmental set up for improving the growth in BOD incubator. The pH range from acidic to alkaline was tested for their role in increasing the biomass and conidial production of C. rosea under liquid cultural condition.

The aim of the study was to find out the dissipation rate of the emamectin benzoate residues in garden bean pods. Insecticides were sprayed at the farmers’ holding located at Naraseepuram, Coimbatore during the year 2022 (March to April) and the collected samples were processed and analysed in the laboratory. An effective modified QuEChERS method was developed and validated to estimate the emamectin residues in Ultra High Performance Chromatography. A good linearity with R2>0.99 was achieved with the Limit of Quantification as 0.05 mg/kg. Relative standard deviation was below 5 % for the recoveries obtained (95.77 to 97.21 %). The residues persisted upto 7 and 10 days after treatment for recommended (11 g a.i./ha) and double the recommended doses (22 g a.i./ha), respectively. The half-life of emamectin in garden bean was calculated as 1.83 days for recommended dose and 2.38 days for double the recommended dose.
Botanical products are the best alternative to chemical insecticides to minimize the negative impact. In this work, Cinnamomum zeylancium essential oils (Laurales: Lauraceae) and Elettaria cardamomum (Zingiberales: Zingiberaceae) were evaluated to determine toxicity, repellent and detrimental effects on progeny of Sitophilus granarius (linnaques) (Coleoptera: Curculiondae) and Tribolium confusum (jacquelindu val) (Coleoptera: Tenebrionidae). Furthermore, to assess grain weight loss percentage. Chemical analysis of the testing materials was conducted using a GC-MS method to recognize the main components of the tested materials which probably had the toxic effect. The obtained results showed that, the two essential oils at all concentrations have higher repellent effect on T. confusum than S. granarius. Elettaria Cardamomum is an effective toxic and repellent agent against the two tested insects at all concentrations. Elettaria cardamomum LC50 values 2.18, 8.96 ml/kg compared to 5.15, 12.97 ml/kg for C. zeylanicum against S. granarius and T. confusum respectively. However, T. confusum is more tolerant. In addition, the two botanical oils inhibited the emerged adults and reduced the weight loss of grains. Chemical analysis of essential oils of C. zeylancium and E. cardamomum revealed that the majority of them was Cinnamaldhyde (63.13%) and a-terpinayl-acetate (47.64%) for C. zeylancium and E. cardamomum respectively.
Production of conventional puddled transplanted rice is facing severe constraints because of water and labor scarcity and climatic changes. Direct Seeded Rice (DSR) is a feasible alternative with good potential to save water, reduce labor requirement, mitigation of green house gases (GHGs) emission and adaptability to climate risks. Considering its importance, an exploratory study was carried out in Haryana state during 2020-21 with an objective to examine the acceptance of DSR cultivation technology and constraints faced by farmers during its acceptance. Present study was conducted in Haryana during 2020 & 2021, Selecting 2 districts randomly, two blocks were selected randomly, from each selected district, further two villages from each selected block and then twenty farmers from each selected village were selected at random. Thus, a total of 160 farmers were selected for the study. The primary data were obtained through personal interview method using a structured interview schedule. Findings of the study revealed that majority of the farmers belonged to middle age group having medium size of farm, educated up to secondary school, medium category of mass media exposure, economic motivation, most of them, i.e. 88.20 per cent belonged to Low to Medium category of The overall adoption of DSR cultivation. However, very serious constraints in acceptance of DSR technology were viz., infestation of weeds, inadequate knowledge of DSR, occurrence of rain before germination, unwillingness to change and non-availability of DSR machine at the time of sowing, etc. The correlation and regression of different variables, i.e. education, land holding, availability of farm equipments, mass media exposure, extension contact, economic motivation, risk orientation and innovativeness exhibited positive and significant correlation with adoption level of DSR technology at 0.05 level of probability.
