Studies were conducted on Carnation (Dianthus caryophyllus L.) to find out the effect of integrated inoculation of potent native isolates of Arbuscular mycorrhizal fungi (AM fungi) and Azotobacter chroocococum with other approaches of management like cultural and biological methods in solarized soil on the incidence of wilt caused by Fusarium oxysporum f.sp. dianthi (Prill. and Del.). Initially, organic amendments, botanicals and bio-control agents were evaluated against wilt to find out the best treatments. Among amendments, neem cake was found most effective with 75.0 per cent reduction in the wilt incidence. Different fungicides, botanicals, bio-pesticides and bio-control agents were also evaluated against wilt by dip treatment of unrooted carnation cuttings. Bavistin among fungicides, Neemazal among botanicals and Trichoderma viride among bio-control agents were found effective with 100.0, 71.1 and 93.6 per cent reduction in the wilt incidence. Based on the best individual treatments, fourteen treatment combinations were evaluated in solarized and unsolarized plots for their efficacy against the disease. Among different treatments, root dip of cuttings in Bavistin (0.1%), soil amendment with Neemcake (1kg/m2), root inoculation with culture of AM fungi and A. chroococcum (5g culture/ plant) and soil application of T. viride formulation (10g/m2) in solarized soil was found most effective with 97.1 per cent reduction in the wilt incidence. This treatment combination also resulted in maximum increase of 50.97, 100.4, 39.2, 57.3, per cent in plant height, number of flowers per plant, flower size and length of flowering stem, respectively in comparison to control.

Effect of soil solarization on viability, disease incidence and incubation period of stem rot of chrysanthemum caused by R. solani

Journal of Pharmacognosy and Phytochemistry (2021)

Ankur Tyagi Harender Raj

A study conducted during 2016 at Nauni to find out the effect of soil solarization with transparent polyethylene mulch (25µm thick) was recorded on soil temperature in the earthen pots and pathogenic potential of the stem rot pathogen mixed in the soil of the earthen pots. Soil solarization increased average maximum soil temperature to 45.9 °C, in the year 2016 with an increase of 7.8 °C at 5 cm soil depth over unsolarized pots. Soil solarization for 40 days resulted in significant reduction in the potential of the pathogen to cause the disease. Soil solarization was observed on disease causing capability of the stem rot pathogen. Sclerotia of Rhizoctonia stem rot pathogen subjected to soil solarization with transparent polyethylene sheet which were put at 5 cm soil depth for 40 days lost the viability of by 88.7 per cent in comparison to unsolarized soil in the pots. Sclerotia of the stem rot pathogen subjected to soil solarization with transparent polyethylene sheet at 5 cm soil depth for 40 days increased the incubation period of the disease by 21.2 per cent i.e. symptoms were delayed and reduced the disease incidence by 46.1 per cent in comparison to unsolarized pots.

Conjoint application of bio-organic and inorganic nutrient sources for improving cropping behaviour, soil properties and quality attributes of apricot (Prunus armeniaca).

The Indian Journal of Agricultural Sciences (2010)

Vishram Singh Som Dev Sharma Pramod Kumar Satish Kumar Bhardwaj Harender Raj

The study was carried out during 2006-08 on 20-year-old 'New Castle' apricot (Prunus armeniaca L.) trees to investigate the conjoint efficacy of bio-organics used along with chemical fertilizers on cropping behaviour, soil properties and quality attributes. Conjoint application of biofertilizers 60 g/tree, vermicompost 30 kg/tree, cow urine 12.5% and 50% NPK resulted in significantly maximum bloom density (25.08%), fruit set (62.38%), yield (29.85 kg/tree), fruit firmness (7.06 kg/cm 2 ), total soluble solids (17.04 °Brix), reducing sugars (3.97%), ascorbic acid (7.29 mg/100 g) and total carotenoids (0.96 mg/100 g). This combination also significantly improved physical, chemical and biological properties of the soil rhizosphere. Available N, P and K content of rhizosphere soil was increased by 34.8, 88.3 and 16.6%, respectively. Micronutrients (Fe, Cu, Zn, Mn) were improved by 15.1, 25.3, 28.7 and 24.1% respectively. The microbial biomass pool in terms of Pseudomonas, Bacillus, Azotobacter chroococcum and Arbuscular mycorrhizal fungi increased by 208.25, 113.40, 383.50 and 442.50% respectively over control.

Pathological survey of green mould rot of Kinnow in various fruits markets and citrus growing regions of Himachal Pradesh

International Journal of Chemical Studies (2018)

K.C. Sharma Harender Raj

Kinnow is the most important fruit crop grown extensively in sub-tropical areas of Himachal Pradesh. Among different fungal post-harvest rots in Kinnow, green mould caused by Penicillium digitatum is most serious. Symptoms of the disease appeared initially as soft, watery and slightly discoloured spots on the surface of fruit rind. During the survey of the disease, incidence of green mould rot ranged between 16.5 to 27.0 per cent recorded. Average severity of disease was recorded maximum in Paonta Sahib (21.33%). While, fruit marketing yard at Theog and Dhalli had lower severity of 13.70 and 15.73 per cent, respectively.

Synergistic strategies for sustainable crop protection: Harnessing soil solarization and biofumigants to combat Damping-off pathogens in Solanaceous vegetable crops

Research Square (Research Square) (2023)

Abstract This study demonstrates the effectiveness of a biofumigants derived from cauliflower leaves and soil solarization technique in combating soil-borne pathogens namely Pythium ultimum, Fusarium oxysporum, Rhizoctonia solani and Sclerotium rolfsii causing damping-off disease in major solanaceous crops such as tomato, chilli and capsicum. Results showed that soil solarization increased the average maximum soil temperature to 41.8°C with an increase of 5.4°C at 5cm soil depth over unsolarized beds. Integration of soil solarization with cauliflower leaves as soil amendment for the period of 40 days at 5cm soil depth was found most effective in reducing the viability of P. ultimum, F. oxysporum, R. solani and S. rolfsii to 5.3, 2.6, 4.6 and 3.6 per cent in comparison to 92.6, 77.3, 83.3 and 80.3 in control respectively. With the increase in the duration of soil solarization from 15 to 40 days, the potential of the pathogens to cause the disease reduced significantly at 5cm soil depth and incidence of the damping-off reduced from 63.3 to 16.6 per cent in tomato; 66.6 to 20.0 per cent in chilli and 70.0 to 23.3 per cent in capsicum. Through this integrated approach, the viability of soil-borne pathogens can be minimized, thereby improves the overall plant health. Thus, these findings give significant evidence for the potential of soil solarization technique and plant-derived biofumigants, paving the way for a newer domain in crop protection in a sustainable manner.
