“…Green mass of the aerial part (GMAP), green root mass (GRM), dry mass of the aerial part (DMAP), and root dry mass (RDM) of sweet pepper plants inoculated with S. rolfsii and treated with T. harzianum in different forms of application. 6/7 (Pastrana et al, 2016), however, for S. rolfsii, this delivery method was less effective and less cost-effective than other control strategies (Konjengbam & Devi, 2020).…”

Soilborne pathogens are difficult to control with limited options, and it is important to seek effective alternatives for management. The objective of this study was to evaluate the effect of Trichoderma harzianum on the biological control of southern blight. The commercial product Trichodermil, containing the antagonist, was used for in vitro antagonism evaluation, followed by in vivo assays, with different forms of biocontrol application in Capsicum annuum seedlings inoculated with Sclerotium rolfsii. The biocontrol conditions used in the tests were: 1) without inoculation of the pathogen; 2) furrow spraying; 3) foliar spraying; 4) immersion of roots in spore suspension; 5) without biocontrol. The T. harzianum isolate tested produces antifungal metabolites that reduce mycelial growth and germination of the pathogen. In the in vivo tests, an effect of the application in the sowing furrow on the root mass of the plants was observed. However, none of the treatments prevented plant mortality. The biocontrol agent T. harzianum does not work as a stand-alone strategy for management of southern blight, but has potential for use in integrated management programs.

A farm testing trial (OFT) was conducted on the 13 farmers’ fields of the Mandsaur district of Madhya Pradesh to assess the most of assessing variety of Kharif onion for two consecutive years i.e. 2018-19 and 2019-20. The present study revealed that onion variety Bhima Dark Red (BDR) performed better for most of the growth parameters, yield and yield attributing traits and economic performance as well as gross and net returns compared to Bhima Super and N-53 varieties. Maximum plant height (63.72 cm), number of leaves per plant (13.17), leaf length (51.85 cm), bulb diameter (5.95 cm), fresh weight of bulb (102.53 g), cured weight of bulb (93.38 g), bulb yield (262.56 q/ha), minimum neck thickness of bulb (1.10 cm) and bolting percentage (0.70%) were observed in Bhima Dark Red. Bhima Dark Red variety recorded an additional net return of Rs. 71,541 and Rs. 198667 over Bhima Super and N-53. Highest B: C ratio was obtained with Bhima Dark Red (6.74) as compared to Bhima Super (5.47) and N-53 (3.42), respectively.

Four systemic, four non-systemic and two combined fungicides at different concentrations were tested in vitro through poison food technique against Aspergillus flavus (Link), a causal organism of afla rot of groundnut. All the fungicides with their respective concentration were found inhibitory to the radial growth of A. flavus. Among all the systemic fungicides the highest growth inhibition of 99.99 per cent was recorded with tebuconazole 25% EC at all concentration (100, 250 and 500 ppm) followed by carbendazim 50% WP at 500 ppm (99.99%), 250 ppm (85.64%) and 100 ppm (82.64%) and hexaconazole 5% EC at 500 ppm (99.99%), 250 ppm (84.75%) and 100 ppm (77.58%). Among non-systemic fungicides, the highest growth inhibition of 90.88, 86.01 and 81.19 per cent were recorded with mancozeb 75% WP at 1500, 1000 and 500 ppm concentration, respectively. Among the combined fungicides, the highest growth inhibition 99.99 per cent was recorded with Carbendazim 12% + Mancozeb 63% WP at concentrations of 1500, 1000 and 500 ppm, respectively.
