Fortification of mulberry leaf with egg albumen and its impact on commercial characteristics of Silkworm (Bombyx mori L.) was conducted at College of Temperate Sericulture Mirgund SKUAST-K during spring 2017. The silkworm double hybrid (CSR6 × CSR26) × (CSR2 × CSR27) was reared on mulberry leaves fortified with aqueous egg albumen solution daily once during fourth and fifth instar. Four different concentrations of egg albumen viz., 5%, 10%, 15% and 20% were tested. Egg albumen improved all the rearing and cocoon characteristics of the silkworm. T5 (20% egg albumen) significantly improved all the parameters registering lowest total larval duration, highest weight of ten mature larvae, cocoon weight, shell weight and shell ratio of 25.33 days, 57.96g, 2.32g, 52.65cg and 22.52% respectively.

One of the main obstacles to feeding the world is the fungal leaf spot disease, which has a negative impact on plants' photosynthetic areas and significantly lowers crop quality and output. To manage fungi that pose a serious hazard to both humans and the environment, various chemical fungicides are utilized. The goal of the current study was to determine whether local isolates of three Trichoderma spp. (Trichoderma viride, Trichoderma harzianum, and Trichoderma asperellum) had any antagonistic effects in vitro against the pathogenic fungi Alternaria alternata, Fusarium solani, Fusarium oxysporum, Aspergillus flavus, Aspergillus sydowii, and Alternaria sp. Trichoderma viride showed the greatest growth inhibition against all of the tested pathogenic fungi, followed by Trichoderma harzianum and Trichoderma asperellum. It was shown that all three Trichoderma species strongly inhibited the mycelial growth of fungal pathogens. Compared to other isolated fungi, Trichoderma species inhibited Alternaria alternata mycelial growth more, whereas in Fusarium oxysporum least amount of mycelial growth inhibition was observed. These findings imply that Trichoderma species can function as an effective biocontrol agent against the fungi responsible for tomato leaf spot disease.

The present studies on the evaluation of different bivoltine silkworm (Bombyx mori L.) breeds on survival against Nuclear Polyhedrosis Virus (Grasserie), under temperate climatic conditions was carried out at College of Temperate Sericulture, SKUAST-Kashmir, Mirgund. Preliminary evaluation of ten silkworm genotypes viz., APS4, APS8, CS6, CSR2, CSR4, DUN-6, DUN-22, NB4D2, SH6 and SANISH8 revealed that APS8 and NB4D2 breed possessed highest tolerance while, CSR2 and CSR4 were highly susceptible to BmNPV Inoculation @ 20,000 PIB'S. The silkworm CSR4 showed drastic decrease in survival rate of (37.33%) in susceptible breed. However in tolerant breed APS8 recorded the survival rate of (72.67%). The maximum pupation rate of 91.36 per cent was recorded in case of NB4D2 and minimum pupation rate of 82.41 per cent was recorded in CSR2.
