SUMMARY

Bio efficacy of newer insecticides was studied against Helicoverpa armigera in chickpea. Novaluron 10 EC was found as superior against H. armigera wrt minimum number of larvae. However, flubendiamide proved significantly superior in terms of minimum pod damage (21.71%), maximum reduction over control (41.18%) and highest yield (3409.26 kg/ha). Next best chemicals with reduction over control were emamectin benzoate 5SG (9.77%), chlorantraniliprole 18.5SC (39.55%), flubendiamide 8.33 + deltamethrin 5.56SC (36.95%), novaluron 10EC (36.33%), novaluron 5.25+ indoxacarb 4.50SC (34.11%), quinalphos 25EC (32.48%) and lambda-cyhalothrin 5EC (22.08%).

SUMMARY

Termites, among the most polyphagous pests, are particularly destructive to wheat crops worldwide. They thrive in loamy or light soils and dry areas lacking adequate irrigation. Research on termite control in wheat under field conditions, focusing on seed treatment and management of standing crops through popular insecticides, is crucial. We examined the effects of insecticidal treatments on termite damage in wheat during two consecutive rabi seasons (2020-21 and 2021-22). The efficacy of the insecticides was evaluated based on plant damage, yield parameters, and cost- benefit analysis. The findings showed that the T₄ treatment (seed treatment and soil application of imidacloprid 17.8 SL after 60 DAS) resulted in the minimum plant damage (0.91%), highest grain yield (29.33 q/ha), highest straw yield (40.76 q/ha), and maximum benefit-cost ratio (2.28). This was followed by the T₆ treatment (seed treatment and soil application of fipronil 5 SC after 60 DAS) and the T₂ treatment (seed treatment and soil application of chlorpyriphos 20 EC after 60 DAS), all of which proved superior to other treatments. The T₇ treatment (soil application of fipronil 0.3 G) was moderately effective, while the T₁ treatment (seed treatment with chlorpyriphos 20 EC) was less effective.

SUMMARY

Foliar diseases (anthracnose, grey leaf spot, zonate leaf spot) and insect-pests (sorghum shoot fly, stem borer) are major restraints in the cultivation of forage sorghum. Host plant resistance is one of the alternative components to manage sorghum shoot fly, stem borer and foliar diseases. In the present study, fifty three sorghum genotypes were screened for varied levels of resistance during Kharif 2021 to 2023. Twelve genotypes viz., SPH1985, SPH 1905, SPV2704, SPV2705, SPV2797, SPV2800, SPV 2985, SPV 2587, SPV 2451, SPV 2881, SPV2886 and SPV 2887 showed resistant disease reaction to anthracnose and grey leaf spot of sorghum. Entries namely SPV2800, SPV2878, SPV 2801, SPV2886 and SPV 2804 showed least percent dead hearts caused by shoot fly, while entries SPV 2800, SPV 2801 and SPV 2886 were also promising against stem borer.

Key words: Sorghum, screening, resistance and foliar diseases

SUMMARY

The present study was conducted during the Kharif season of 2024 at the Instructional Farm, Department of Entomology, MPKV, Rahuri to evaluate the bioefficacy of selected insecticides against the fall armyworm, Spodoptera frugiperda. Six treatments, Thiamethoxam + Lambda- cyhalothrin, Spinetoram, Chlorantraniliprole, Emamectin benzoate, Lufenuron + Emamectin benzoate and an untreated controlwere planned in a Randomized Block Design with four replications. Insecticides were applied three times at 10dayintervals after the pest population reached the economic threshold level. Among the evaluated insecticides, Spinetoram 11.7% SC recorded the lowest infestation (9.77%) and showed superior performance compared to the remaining treatmentswhich exhibited 12.52 to 46.04% infestation. Chlorantraniliprole 47.85% SC and Emamectin benzoate 5% SG were the next effective treatments. Spinetoram also resulted in the highest cob yield (8.41 t/ha) and the maximum incremental cost-benefit ratio (1:6.47). The findings identify Spinetoram as the most effective and economically viable insecticidal option for sustainable management of fall armyworm in maize.

SUMMARY

The present study reports the first record of Conicobruchus albopubens (Pic) infesting stored cluster bean (Cyamopsis tetragonoloba L. Taub.) seeds from Haryana, India, along with documentation of the nature of infestation. Infested seed samples were collected from seed stores of CCSHAU, Hisar and farmer-saved seed lots from Bhiwani and Mahendergarh districts during 2025. Adult beetles were reared and identified using standard morphological taxonomic keys. The specimens were characterized by black body uniformly covered with white setae, bicoloured antennae, slender hind femur without denticles and subvertical pygidium. Larval feeding caused internal seed damage following oviposition on seed surfaces, leading to gum exudation, seed aggregation and deterioration of storage quality. This finding extends the geographical distribution of C. albopubens and highlights its potential as an emerging storage pest of guar. The study emphasizes the need for regular monitoring and appropriate management strategies to minimize post-harvest losses in guar seed storage systems.

SUMMARY

In the present study a field experiment was conducted by using 40 genotypes of Chenopodium quinoa including checks at Research Farm of MAP Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar and experimental area of Department of Plant Breeding and Genetics, PAU, Ludhiana. In the present study, wide genetic variability was observed for all the characters studied. The seed yield at Hisar (E₁) varied from 10.3 to 312.0 g/plant. Out of 40 genotypes, the genotype EC896083 recorded the highest seed yield (312.0g/plant) followed by EC896202 (275.0), EC896115 (268.3), EC896097 (250.0) and EC896111 (241.7). However, in environment E₂ (Ludhiana) the seed yield varied from 10.3 to 312.0 g/plant. Out of 40 genotypes, the genotype EC896098 recorded the highest seed yield (290.0g/plant) followed by EC-507741 (266.7), EC896209 (265.0), SSQC-1 (258.3), EC896111 (225.0), EC896215 (225.0) and EC896115 (216.7) On average basis, it was observed that the genotypes, EC896115 recorded the highest seed yield (242.5g/plant) and EC896202 (242.5) followed by EC896111 (233.4), EC896209 (233.4), EC896083 (223.5), EC896097 (221.7) and EC896212 (200.0). The seed yield was significantly and positively correlated with leaf length (0.377), leaf width (0.424), petiole length (0.541) and number of inflorescence per plant (0.340). These genotypes have good potential for yield and its contributing traits, therefore, may be utilized in the breeding programme.

SUMMARY

The application of micronutrient and their combinations were tried to improve the productivity of chickpea on sandy loam soils of Western Rajasthan during Rabi 2022-23. The experiment comprised of eight treatments in four replications and laid out in randomized block design (RBD) using cultivar CSJ 515. The maximum seed yield (1946 kg/ha) was recorded under treatment RDF + 0.5% ZnSO₄ + 0.5% FeSO₄ +0.2% B spray at flower initiation as compared to RDF (1648 kg/ha). However, the application of micro nutrient alone or in combination increased the growth and yield attributes but they were at par with RDF (10 kg N and 30 Kg P₂O₅/ha) except two sprays of 0.5% ZnSO₄ and 0.5% ZnSO₄ + 0.5% FeSO₄ +0.2% B spray at flower initiation and pod formation. The maximum net returns (69689 Rs./ha) and a benefit to cost ratio (3.17) was recorded in RDF + 0.5% ZnSO₄ + 0.5% FeSO₄ +0.2% B spray at flower initiation.
