However, limited research has been conducted on SHD management using trunk injection delivery systems in Gilgit-Baltistan, Pakistan. In this study, the efficacy of individual (Bordeaux mixture (BM), Capparis spinosa (CP), Mentha piperita (MP), Artemisia vulgaris; (AV) and in combination (BM + MP, BM + CP, BM + AV) of BM and plant extracts treatments were evaluated against SHD. The experiment was conducted in the apricot orchards during 2022-23 as a complete randomized block design under factorial arrangement. The analysis of variance showed significant (P ≤ 0.5) variation in SHD incidence among the treatments. Among individual treatments, BM was the most effective against SHD with 27.4% incidence, followed by AV (39.8%), whereas CP and MP were moderately efficacious (means: 43.03% and 43.14%, respectively). The control treatment showed extremely high disease occurrence (73.77%). Moreover, the highest effectiveness was found in the combination treatments. BM + MP reduced the disease incidence rate to 29.67%, followed by BM + CP (47.32%), which provided a more stable form of disease suppression. Hence, BM alone and in combination with plant extracts effectively reduce SHD. These results highlight the potential of plant-based trunk injection treatments for SHD management, with BM + MP offering the most effective control.

They are rich in essential nutrients, (sugars, fibers, amino acids, vitamins, and minerals), health promoting phytochemicals (phenolics compounds, flavonoids, carotenoids and tannins) and minerals. Berberry spices are a valuable medicinal shrub grown in Asia and Europe. Berberry have a distinct position due to many traditional pharmacological uses. The physio-chemical and phytochemical analyses of berberry (B. Calliobotrys B. orthobotrys B. psedumbellata) fruit were carried out to determine its nutritional and phytochemical constituents. The different parameters which were observed during the studies were, pH (3.91, 3.52 and 3.33), TSS, (20.22, 18.18 and 15.56 ⁰ Brix) titrateable acidity (2.26, 2.18 and 1.36% citric acid), ash (0.79, 1.05 1.13%) , moisture (80.47, 74.96 and 80.13%), total sugars (14.98, 12.44 and 12.99 %) reducing sugars (9.00, 7.23and 7.68) non-reducing sugars 6.10, 5.45 and 5.95% ) crude protein (...

This study was aimed to determine the levels of selected heavy metals i.e. cadmium (Cd), chromium (Cr), copper (Cu) manganese (Mn),
and nickel (Ni) in various sources such as drinking water, vegetables, and soil in districts Ghizer and Gilgit, Pakistan. Human health risks were assessed using deterministic indices, a probabilistic approach, and multi
variate analysis. The determinations were carried out by pectrophotometrically (AAS-700, Perkin Elmer, USA) following the standard procedures for heavy metal levels. The mean concentration was recorded as Cd 0.036 mg/L, Cr 0.076 mg/L, and Ni 0.394 mg/L, respectively. It revealed an exceeded level for Cd (0.03 mg/L) and Cr (0.07
mg/L) against the safe limits in drinking water of Gilgit and Ghizer. The highest hazard quotient (HQ) was recorded as Cd 3000, Cr 3863.33, Cu 21.7, Mn 45.71, and Ni 22.35 for children regarding the consumption of
vegetables from district Ghizer. Whereas higher HQ values were recorded for adults regarding consumption of vegetables from district Gilgit. A hazard index (HI) indicates significant non-carcinogenic health risks (HI > 1) in Ghizer and Gilgit drinking water and vegetables. Gilgit soil HI values exceeded more than one due to dermal contact, while HI > 1 due to oral and dermal exposure in Ghizer. Furthermore, drinking water samples and
vegetables from both districts showed cancer risk (CR) > 1 × 10–4. The cumulative lifetime cancer risk (CR) was observed as 88.61 and 65.61 for adults whereas 2. 98 and 0.38 for children pertaining to vegetable consumption from Ghizer and Gilgit. It was found that the lifetime cancer risk (LCR) for Ghizer was higher than that for Gilgit, based on soil dermal and oral contact. Monte Carlo Simulation revealed adverse health risks in children as compared to adults. As a result of exposure to toxic metals, drinking water and vegetable consumption have higher cancer-causing risks. Therefore, we recommend that both districts implement strict monitoring regulations for drinking water and vegetables.

levels of harmful metals in drinking water, vegetables, and soil can accumulate in the body,
leading to serious health issues. In Gilgit-Baltistan, Pakistan, the prevalence of cancer is
notably high, and heavy metals are considered among the possible risk factors. In this
study, the distribution of heavy metals, e.g., Cd, Mn, Cu, Cr, and Ni, in the drinking water,
vegetables, and soil in the Gilgit and Skardu Districts was assessed. A geo-accumulation
index was combined with a deterministic technique to examine potential carcinogenic and
non-carcinogenic impacts on human health. Cr and Ni levels in drinking water exceeded
the permissible limits from both districts. Drinking water had a HQ > 1 for Cd, Cr, Ni, and
Mn, posing significant non-carcinogenic health effects. The lifetime cancer risk (LCR) by
drinking water for Cd, Cr, and Ni in Gilgit (0.0087, 0.55, and 0.0048) and Skardu (0.071, 0.21,
and 0.014) indicated a considerable cancer risk (>1 × 10−4
) for adults. The cancer risk for
vegetable intake was observed within the safe limit, while LCR_ingetsion > LCR_dermal
and LCR_inhalation for the soil samples in both regions. These findings highlight the need
for regular monitoring, enhanced waste management, and advanced purification methods
to reduce cancer risk, lower heavy metal contamination, and safeguard public health in
the region.

There are many biotic and abiotic threats to its production. Amongst them the black scurf disease caused by Rhizoctonia solani is the major constraint. In order to assess black scurf of potato a comprehensive survey was carried out in four main valleys of the region consisting of 24 villages. The survey revealed that valley wise mean disease prevalence was high in Bagrote (63.85±9.06) and low in Haramosh (45.40±14.62). Maximum mean disease incidence and severity were recorded in Hoper valley while least disease incidence appeared in Haramosh and severity in Bagrote valley. Production practices as risk factor were assessed through a questionnaire. The majority of farmers performed activities in field that were supportive to the black scurf epidemics, such as, use of pits for storage of late harvested potato tuber for growing in next season, table potato, lack of general awareness about black scurf, not maintaining proper depth of sowing, irrigation, harvesting time and crop rotation. In vitro efficacy of three fungicides at different concentrations i.e. 50, 100, 150 and 200 ppm were tested against Rhizoctonia solani isolates. Results indicated that increase of fungicide concentration significantly inhibited the mycelial growth of respective isolates. However, sensitivity reaction of each of isolates against each fungicide was also differential. Fungicide ridomil gold and mencozeb showed more toxic effect against the fungus compared to vitavax.

In this investigation Desi and Kabuli varieties were compared for these oligosaccharides and phenolic compounds. Furthermore, the effect of different processing and cooking methods such as soaking, cooking and germination in the reduction of these antiphysiological factors were are also studies. Maximum tannic acid (0.90 ± 0.20%) was observed in Parbat and C-44 while minimum (0.60 ± 0.04%) in Karak-2. Stachyose contents ranged between 1.10 ± 0.05 (Karak-3) to 1.42 ± 0.02% (Parbat) while raffinose was 0.63 ± 0.05(Karak-3) to 0.81 ± 0.02% (Dasht). The highest tannic acid content was reduced up to 50% in C-44 by cooking of 72 hours germinated seeds. Stachyose and raffinose contents were completely removed after 72 hours germination. Present studies revealed that cooking after germination is the most effective method to reduce the anti-nutritional factors of chickpea. Individually, soaking and cooking also contributed to the loss of the same factors but to a lesser extent.
