Acetamiprid 20SP, spinosad 45SC, fenpyroximate 5EC, emamectin benzoate 5SG, fipronil 80WG, spiromesifen 22.9SC, diafenthiuron 50WP, acephate 75 SP and dimethoate 30EC were included. Among these, fipronil 80WG and spiromesifen 22.9SC were found superior with least incidence (0.98 and 1.04 thrips/ leaf, respectively) and 75.6 and 74.1% reduction over untreated control, respectively. Spiromesifen 22.9SC led to maximum reduction in leaf curl and fruit curl (84.6 and 83.1%, respectively) with maximum chlorophyll content in leaves and green chilli yield (93.85 q/ ha).

Approximately 5 kg potatoes of each genotype were kept inside perforated plastic containers under ambient temperature for this study. Rottage of tubers on number and weight basis were recorded at 30, 60, 75 and 90 days. Similarly sprouting of tubers in different genotypes was recorded at 75 and 90 days. It was observed that the percentage of tuber rottage on weight basis at the end of storage period (90 days) varied from 2.5% in Kufri Ashoka to 65.1% in Kufri Sinduri. There was also wide variation among different genotypes for sprouting at 75 and 90 days. Five genotypes did not sprout even at 90 days under storage at ambient temperature.

Insecticides are commonly employed to control this pest, but their use often escalates production costs and fosters pesticide resistance. Identifying insect-resistant rice genotypes and their resistance mechanisms is crucial for successful pest management. New sources of resistance providing long-lasting protection against leaffolder can be identified by studying the morphobiochemical characteristics of different rice genotypes. This study explored the role of various morphological traits of certain genotypes that confer resistance. Different biochemical constituents like soluble protein, phenol, total soluble sugar and enzymes viz., peroxidase, polyphenol oxidase and catalase were assessed spectrophotometrically in all infested and uninfested genotypes along with standard resistant (TKM6) and susceptible (TN1) checks. Leaffolder damage was negatively significant with pla...

Realizing the importance and nutritional superiority of millets, they are considered as nutri-cereals. Finger millet (Ragi) Eleusine coracana Gaertn is the most widely cultivated one among the small millet group. Ragi crop is grown generally in tribal dominated areas of Odisha. Finger millet pink stem borer, Sesamia inferens Walker (Noctuidae; Lepidoptera) is one of the most important insect pest of finger millet during Rabi season in Odisha. Among the eco-friendly pest management practices, the identification of pest resistant cultivars is an economical, easy and sustainable strategy which is very essential to increase the production and productivity. An experiment was conducted at CPR, Berhampur of Odisha University of Agriculture and Technology (OUAT) for screening of finger millet (Ragi) genotypes against stem borer incidence during Rabi, 2012-13 and Rabi, 2013-14. Twenty nine finger millet genotypes were included in the test. The genotypes, PRM 9002, KOPN 933, OEB 28, RAU 8 and Champabati recorded less stem borer incidence both in tillering(<10%) stage and panicle stage(<5%). Among the tested genotypes OEB-28 recorded tallest plant (68.2 cm height), highest number of tillers (2.32 plant-1), longest finger length (7.0 cm), highest grain yield (19.5 q/ha) and straw yield (2.39 t/ha).

Under the umbrella of All India Co-ordinated Small Millet Improvement Project (AICSMIP) the experiment was conducted on varietal screening of finger millet crop against major insect pests and population dynamics of natural enemies during Kharif 2012 at Centre for Pulse Research (CPR), Berhampur, Odisha. Twenty eight entries of initial varietal trial (IVT) along with two local check varieties were included in the experiment. From the observations recorded it was observed that no major insect pests were affecting finger millet crop. During the early growth stage grasshoppers were defoliating the leaves. Among sucking insects only aphid infestation was marked. The observations on subsequent days noticed the naturally occurring predators like spiders and coccinellid predators. The fingers of Ragi provide a p...
